However, because the temperature inside the structure and the temperature outside the structure are different, an energy loss problem arises between the inside and outside of the structure. 【0025】 To solve the above problem, an insulating layer is provided between the interior and exterior of the structure. However, due to heat conduction between the insulating layer and the exterior of the structure, the temperature of the insulating layer approaches the temperature of the exterior of the structure. Therefore, the degree of discrepancy between the temperature of the insulating layer and the temperature inside the structure becomes large, making it difficult to solve the above problem. 【0026】Further improvements could be made to incorporate an insulating layer with low thermal conductivity, or to increase the thickness of the insulating layer. However, incorporating an insulating layer with low thermal conductivity and increasing its thickness incurs high costs. As a result, the cost of the insulating layer itself would exceed the cost of energy loss. Furthermore, there are limits to how low the thermal conductivity of the insulating layer can be, making it difficult to solve the above problems simply by incorporating an insulating layer with low thermal conductivity. Below, an example embodiment of an equipment system that contributes to solving the above problems will be described. 【0027】 <Premise> The following premise for the embodiment is explained below. Front means the negative Z direction, back means the Z direction, left means the negative X direction, right means the X direction, down means the negative Y direction, and up means the Y direction. Depth is the length in the Z direction. Width is the length in the X direction. Height is the length in the Y direction. 【0028】 An oblique view is a view from diagonally above.

The greenhouse 10 mainly consists of a front wall 11, a left side wall 12, a right side wall 13, a rear wall 14, and a ceiling 15. 【0036】 The front wall 11, the left wall 12, the right wall 13, and the rear wall 14 are vertical walls erected approximately perpendicular to the ground T. The front wall 11, the left wall 12, the right wall 13, the rear wall 14, and the ceiling 15 are components that are in contact with the outside O. 【0037】An entrance / exit D is provided in the front wall 11. The entrance / exit D is an entrance from the outside O to the inside I1. The entrance / exit D is also an exit from the inside I1 to the outside O. The entrance / exit D may be a structure that can be opened and closed (opening / closing opening) or a structure that is open (opening). The left wall 12, the right wall 13, and the ceiling 15 are not provided with windows or entrance / exit D. 【0038】 The ceiling 15 faces the ground T and is connected to the front wall 11, the left side wall 12, the right side wall 13, and the rear wall 14. The shape of the ceiling 15 is curved, but it may also be flat. 【0039】 An opening V is provided in the center of the ceiling 15 in the X direction. The opening V is located vertically above the vertical center of the greenhouse 10. The opening V is an opening through which air A flows from the inside I1 to the outside O. A ventilation device (not shown) is provided in the opening V. The ventilation device is a device that drives air A from the inside I1 to the outside O. 【0040】 The ceiling 15 is a first component. The first component is a component of the greenhouse 10 that is in contact with the outside O and is provided with an opening V. 【0041】 The front wall 11, the left side wall 12, the right side wall 13, and the rear wall 14 are second components. The second components are components of the greenhouse 10 that are in contact with the outside O and do not have openings V. 【0042】 The area of ​​the ground T opposite the ceiling 15 is enclosed by the front wall 11, the left side wall 12, the right side wall 13, the rear wall 14, and the ceiling 15, thereby forming the interior I1. 【0043】 (2-2) Figure 3 is a perspective view showing the detailed configuration of equipment 100. Figure 4 is a front view showing the detailed configuration of equipment 100. Figure 5 is a rear view showing the detailed configuration of equipment 100. Figure 6 is a left side view showing the detailed configuration of equipment 100. Figure 7 is a right side view showing the detailed configuration of equipment 100. Figure 8 is a top view showing the detailed configuration of equipment 100. Equipment 100 mainly consists of a first member 101, a second member 102A, a second member 102B, a filler material 103A, and a filler material 103B. 【0044】 (2-2-1) First member The first member 101 is a member provided at a distance d1, which is the distance between the ceiling 15 and the first member 101, from the ceiling 15. The length of the first interval d1 is 2 cm or more and 10 cm or less, but is not limited thereto. The first interval d1 is substantially equally spaced over substantially the entire area between the first member 101 and the ceiling 15 where the first interval d1 is formed. 【0045】 The shape of the first member 101 is curved. The first member 101 is provided so as to face the opening V and substantially the entire area of the ceiling 15. The first member 101 has four end portions: a left end portion 101L, a right end portion 101r, a front end portion 101f, and a rear end portion 101b. 【0046】 The first member 101 is connected to the upper end portion 102Au at the left end portion 101L. The first member 101 is connected to the upper end portion 102Bu at the right end portion 101r. The first member 101 is connected to the filler 103A at the front end portion 101f. The first member 101 is connected to the filler 103B at the rear end portion 101b. At all the end portions of the first member 101, the first interval d1 is not communicated with the outside O. 【0047】 (2-2-2) Second member The second member 102A is a member provided at a distance d2, which is the distance between the left side wall 12 and the second member 102A, from the left side wall 12. The second interval d2 is substantially equally spaced over substantially the entire area between the second member 102A and the left side wall 12 where the second interval d2 is formed. The second interval d2 is substantially equally spaced with the first interval d1. 【0048】 The shape of the second member 102A is plate-like. The second member 102A is provided so as to face an area of more than half of the left side wall 12. The second member 102A has four end portions: an upper end portion 102Au, a front end portion 102Af, a rear end portion 102Ab, and a lower end portion 102Ad. 【0049】The second member 102A is connected to the left end 101L at its upper end 102Au. Therefore, the first interval d1 and the second interval d2 are in communication at the upper end 102Au and the left end 101L. The second member 102A is connected to the filler material 103A at its front end 102Af. The second member 102A is connected to the filler material 103B at its rear end 102Ab. The second member 102A is not connected to any other components of the equipment 100 at its lower end 102Ad. Therefore, the second interval d2 is in communication with the outside O at its lower end 102Ad. The second interval d2 is in communication with the outside O vertically below the vertical center of the greenhouse 10. 【0050】 The second member 102B is provided with a second interval d3 between the right side wall 13 and the second member 102B, which is the distance between the right side wall 13 and the second member 102B. The second interval d3 is approximately equal in length across substantially the entire area between the second member 102B and the right side wall 13 where the second interval d3 is formed. The second interval d3 is approximately equal in length to the first interval d1 and the second interval d2. 【0051】 The second member 102B has a plate-like shape. The second member 102B is provided so as to face more than half of the area of ​​the right side wall 13. The second member 102B has four ends: an upper end 102Bu, a front end 102Bf, a rear end 102Bb, and a lower end 102Bd. 【0052】 The second member 102B is connected to the right end 101r at its upper end 102Bu. Therefore, the first interval d1 and the second interval d3 are in communication at the upper end 102Bu and the right end 101r. The second member 102B is connected to the filler material 103A at its front end 102Bf. The second member 102B is connected to the filler material 103B at its rear end 102Bb. The second member 102B is not connected to any other components of the equipment 100 at its lower end 102Bd. Therefore, the second interval d3 is in communication with the outside O at its lower end 102Bd. The second interval d3 is in communication with the outside O vertically below the vertical center of the greenhouse 10. 【0053】The configuration of the second member 102A is the same as that of the second member 102B. Since the opening V is located in the center of the ceiling 15 in the X direction, the shortest distance from the lower end 102Ad to the opening V and the shortest distance from the lower end 102Bd to the opening V are the same. 【0054】 Furthermore, a mesh-like member may be provided at the second interval d2 at the lower end 102Ad and the second interval d3 at the lower end 102Bd to prevent the entry of animals (birds, insects, etc.). 【0055】 (2-3) Filler The filler 103A fills the first gap d1 at the front end 101f so that the first gap d1 is not in communication with the outside O. The filler 103A fills the second gap d2 at the front end 102Af so that the second gap d2 is not in communication with the outside O. The filler 103A fills the second gap d3 at the front end 102Bf so that the second gap d3 is not in communication with the outside O. 【0056】 The filler material 103B fills the first gap d1 at the rear end 101b so that the first gap d1 is not connected to the outside O. The filler material 103B fills the second gap d2 at the rear end 102Ab so that the second gap d2 is not connected to the outside O. The filler material 103B fills the second gap d3 at the rear end 102Bb so that the second gap d3 is not connected to the outside O. 【0057】 The shape of the filler material 103A and filler material 103B is elongated and U-shaped. The filler material 103A and filler material 103B are pre-processed so that they can be fitted into the first gap d1, the second gap d2, and the second gap d3. Alternatively, the filler material 103A and filler material 103B may be formed by later filling the first gap d1, the second gap d2, and the second gap d3 with expanded polystyrene or expanded urethane, etc. 【0058】 Filler material 103A and filler material 103B fill the first gap d1 at all ends of the first member 101 except for the left end 101L where the first gap d1 and the second gap d2 are connected, and the right end 101r where the first gap d1 and the second gap d3 are connected. 【0059】(3) The flow of air A from the interior I1 in the airflow equipment system 1 will be explained. The air conditioner supplies air A, which is warmer than the outside O, to the interior I1. The ventilation device is driven to circulate air A. Figure 9 is a schematic diagram of the equipment system 1 showing the flow of air A. 【0060】 As the ventilation device is activated, air A flows into the opening V inside I1 (not shown). Air A is drawn into the opening V by the ventilation device (not shown). Air A is blown out by the ventilation device into the first gap d1 between the opening V and the first member 101 (not shown). 【0061】 The second gap d2 is connected to the outside O at its lower end 102Ad. The second gap d3 is connected to the outside O at its lower end 102Bd. Therefore, the air pressure in the second gaps d2 and d3 is close to the atmospheric pressure of the outside O. On the other hand, the air pressure in the first gap d1 is higher than atmospheric pressure because air A is blown out from the opening V. Therefore, the air pressure in the first gap d1 is higher than the air pressure in the second gaps d2 and d3. 【0062】 Due to the pressure difference, the air A blown out from the opening V flows toward the lower end 102Ad or the lower end 102Bd. The air A blown out from the opening V flows toward the first interval d1 at the left end 101L or the right end 101r. 【0063】 The air A that flows through the first gap d1 at the left end 101L flows to the second gap d2 at the lower end 102Ad. From the second gap d2 at the lower end 102Ad, the air A flows to the outside O. The air A that flows to the outside O is warmer than the outside O. Therefore, the air A that flows to the outside O flows upward from the lower end 102Ad. 【0064】 The air A that flows through the first gap d1 at the right end 101r flows to the second gap d3 at the lower end 102Bd. From the second gap d3 at the lower end 102Bd, the air A flows out to the outside O. The air A that flows out to the outside O is warmer than the outside O. Therefore, the air A that flows out to the outside O flows upward from the lower end 102Bd. 【0065】Almost the entire area of ​​the ceiling 15 is enveloped by air A flowing through the first interval d1. More than half of the left wall 12 is enveloped by air A flowing through the second interval d2. More than half of the right wall 13 is enveloped by air A flowing through the second interval d3. Therefore, the interior I1 is enveloped by air A flowing through the first interval d1, the second interval d2, and the second interval d3. 【0066】 The second member 102A is enveloped by air A flowing upward from its lower end 102Ad in the outside O. In other words, more than half of the left wall 12 is enveloped by air A flowing upward from its lower end 102Ad in the outside O. The second member 102B is enveloped by air A flowing upward from its lower end 102Bd in the outside O. In other words, more than half of the right wall 13 is enveloped by air A flowing upward from its lower end 102Bd in the outside O. Therefore, the interior I1 is enveloped by air A flowing upward from its lower end 102Ad in the outside O and air A flowing upward from its lower end 102Bd in the outside O. 【0067】 (4) Features (4-1) The equipment 100 includes a first member 101 which is a component of the structure that is in contact with the outside O of the structure and is provided with an opening V through which air A flows from the inside I1 of the structure to the outside O, and is provided with a first member 101 which is a first interval d1 which is a distance from the first component. The first member 101 is provided so as to face the opening V and more than half of the area of ​​the first component so that air A flows from the inside I1 to the outside O through the first interval d1. 【0068】 In structures, ventilation is carried out to remove odors, mites, mold spores, dust, viruses, bacteria, allergens, smoke, and other pollutants by circulating air from the inside to the outside of the structure. Ventilation is also carried out in structures to regulate temperature, humidity, carbon dioxide concentration, and oxygen concentration. In particular, in greenhouses where plants are cultivated, ventilation is carried out to supply plants with an appropriate amount of carbon dioxide. 【0069】The equipment 100 includes a first member 101 that is positioned to face the opening V and more than half of the ceiling 15. Air A flows through a first gap d1 formed in more than half of the ceiling 15. The temperature of air A from the interior I1 is close to the temperature of the interior I1. The thermal conductivity of air A is lower than that of a tangible insulating layer. Because air A is flowing, the time for heat conduction between air A and the outside O is short. Even when heat conduction occurs between air A and the outside O, the heat-conducted air A flows to the outside O. 【0070】 More than half of the ceiling 15 is enveloped by a flow of air A, which is at a temperature close to that of the interior I1 and has a lower thermal conductivity than tangible objects. In other words, an insulating layer is formed between more than half of the ceiling 15 and the outside O by the flow of air A. Therefore, energy loss between the outside O and the interior I1 is suppressed by the flow of air A. The equipment 100 can achieve energy savings in the interior I1 of the greenhouse 10. 【0071】 Furthermore, the equipment 100 utilizes the airflow A generated by ventilation. Therefore, when using an insulating layer made of a tangible material with low thermal conductivity, the equipment 100 can form an insulating layer with higher cost performance compared to when a thick insulating layer made of a tangible material is used. 【0072】 Furthermore, the equipment 100 can be attached externally to the existing greenhouse 10 and does not occupy the internal space I1. 【0073】 (4-2) The equipment 100 is provided such that the first member 101 faces the opening V and substantially the entire area of ​​the first component so that air A flows from the inside I1 to the outside O through the first gap d1. 【0074】 A thermal insulation layer is formed between the ceiling 15 and the outside O by the flow of air A. As a result, the equipment 100 can achieve energy savings in the interior I1 of the greenhouse 10. 【0075】 (4-3) The facility 100 is equipped with a ventilation device at the opening V that drives air A from the inside I1 to the outside O. 【0076】In environments where there is little difference between the air pressure inside and outside a structure, natural ventilation is difficult. As a result, airflow slows down, and air stagnates in some areas. This makes it difficult to suppress energy loss between the inside and outside of the structure. 【0077】 The opening V is equipped with a ventilation device that drives air A through it. The air A in the first interval d1 flows widely and quickly due to the ventilation device. Therefore, even in environments where there is little difference between the air pressure inside I1 and the air pressure outside O, the equipment 100 can suppress energy loss between the inside I1 and the outside O. Consequently, the equipment 100 can achieve energy savings in the inside I1 of the greenhouse 10. 【0078】 (4-4) The equipment 100 further includes filler material 103A and filler material 103B that fill the first gap d1 at at least one substantially end of the first member 101 so that the first gap d1 is not in communication with the outside O. 【0079】 At the front end 101f and the rear end 101b, the first gap d1 is not in communication with the outside O. Therefore, air A is unlikely to flow through the front end 101f and the rear end 101b. Air A flows to the left end 101L or the right end 101r, where the first gap d1 is not filled. The equipment 100 can form an air A flow in a predetermined direction and form a heat insulating layer of a predetermined nature. Thus, the equipment 100 can achieve energy savings on the interior I1 of the greenhouse 10. 【0080】 (4-5) The equipment 100 has a first interval d1 which is approximately equal in length over almost the entire area where the first interval d1 is formed. 【0081】 Therefore, the flow of air A in the first interval d1 becomes less turbulent. The time during which heat conduction occurs between air A and the outside O is also shortened. Even when heat conduction occurs between air A and the outside O, the heat-conducted air A flows quickly to the outside O. Consequently, the equipment 100 can achieve energy savings in the interior I1 of the greenhouse 10. 【0082】(4-6) The equipment 100 is a first component that does not have a window, an entrance from the outside O to the inside I1, or an exit from the inside I1 to the outside O. 【0083】 If the first component is provided with at least one of a window, an inlet, and an outlet, the first member must be provided so as to avoid the areas of the window, inlet, and outlet. As a result, the shape of the first member may be distorted, and turbulence may occur in the first gap between the first member and the first component. 【0084】 The first member 101 is installed facing the ceiling 15, which does not have windows or entrances D. The first gap d1 is not distorted in shape by the windows and entrances D, and is less likely to generate turbulence. Therefore, the equipment 100 can achieve energy savings in the interior I1 of the greenhouse 10. 【0085】 (4-7) The equipment 100 further comprises a second member 102A provided at a distance of a second interval d2 from a second component, which is a structural component that is in contact with the outside O and does not have an opening V. The equipment 100 further comprises a second member 102B provided at a distance of a second interval d3 from the second component. The second member 102A is provided such that the first interval d1 and the second interval d2 are in communication with each other so that air A flows from the inside I1 to the outside O through the first interval d1 and the second interval d2. The second member 102B is provided such that the first interval d1 and the second interval d3 are in communication with each other so that air A flows from the inside I1 to the outside O through the first interval d1 and the second interval d3. 【0086】 Therefore, the equipment 100 can form an insulating layer not only at the first interval d1, but also at the second intervals d2 and d3. Consequently, the equipment 100 can achieve energy savings in the interior I1 of the greenhouse 10. 【0087】(4-8) The equipment 100 further includes filler material 103A and filler material 103B to fill the first gap d1 at at least one substantially end of the first member 101 so that the first gap d1 is not in communication with the outside O. Filler material 103A and filler material 103B fill the first gap d1 at all substantially ends of the first member 101 except for the substantially end of the first member 101 where the first gap d1 is in communication with the second gap d2 or the second gap d3. 【0088】 Therefore, all the air A in the first gap d1 flows to the outside O through the second gap d2 or the second gap d3. The equipment 100 can form an insulating layer with widely and rapidly flowing air A in the second gap d2 and the second gap d3. Thus, the equipment 100 can achieve energy savings in the interior I1 of the greenhouse 10. 【0089】 (4-9) The equipment 100 has a first interval d1, a second interval d2, and a second interval d3 that are approximately equal in length. 【0090】 If the first and second intervals are not equal in length, the airflow from the first to the second interval can become turbulent. In facility 100, the first interval d1, the second interval d2, and the second interval d3 are approximately equal in length. Therefore, the airflow A from the first interval d1 to the second interval d2 and the airflow A from the first interval d1 to the second interval d3 are less likely to become turbulent. Consequently, facility 100 can achieve energy savings in the interior I1 of the greenhouse 10. 【0091】 (4-10) The equipment 100 comprises a plurality of second members (second member 102A, second member 102B). When the second intervals (second interval d2, second interval d3) at the approximate ends of each plurality of second members (second member 102A, second member 102B) are in communication with the outside O, the shortest distance from the approximate ends of each plurality of second members (second member 102A, second member 102B) to the opening V is approximately the same. 【0092】 Even if multiple second members are provided, if the airflow is unevenly distributed across some of the second members, it becomes difficult to form an insulating layer over the other second members. As a result, energy loss across the other second member cannot be suppressed. 【0093】 The shortest distance from the lower end 102Ad to the opening V and the shortest distance from the lower end 102Bd to the opening V are approximately the same. Air A flows without bias towards either the second gap d2 in the second member 102A or the second gap d3 in the second member 102B. Equipment 100 can form an insulating layer covering both the second member 102A and the second member 102B. Therefore, equipment 100 can achieve energy savings in the interior I1 of the greenhouse 10. 【0094】 (4-11) The opening V of the equipment 100 is located approximately vertically above the approximate vertical center of the structure. The second intervals d2 and d3 are located approximately vertically below the approximate vertical center of the structure and communicate with the outside O. 【0095】 If the opening from which air is blown into the second interval is close to the location from which air flows out of the second interval, the air can be immediately blown out of the opening. As a result, the air does not flow throughout the entire area of ​​the second interval, and a wide and fast-flowing insulating layer of air is not formed. 【0096】 The opening V is located vertically above the vertical center of the greenhouse 10. On the other hand, the second intervals d2 and d3 are located vertically below the vertical center of the greenhouse 10 and communicate with the outside O. Air A flows from vertically above where the opening V is located to vertically below where it communicates with the outside O. Air A flows widely and quickly through the first interval d1, the second interval d2, and the second interval d3. Therefore, the equipment 100 can achieve energy savings in the interior I1 of the greenhouse 10. 【0097】 The second intervals d2 and d3 communicate with the outside O vertically below the vertical center of the greenhouse 10. When the interior I1 is heated, the air A flowing to the outside O is warmer than the outside O. The air A that flows to the outside O flows upward. The upward-flowing air A envelops the greenhouse 10 from the outside of the second members 102A and 102B. The equipment 100 can form a double insulation layer on the left wall 12 and the right wall 13. Therefore, the equipment 100 can achieve energy savings on the interior I1 of the greenhouse 10. 【0098】 (5) Modifications: The following descriptions will focus on the differences from the first embodiment, omitting explanations of points similar to those in the first embodiment. 【0099】 (5-1) Modification 1A (5-1-1) The structural equipment 100 may further include a second member 102C. The rear wall 14 is not provided with windows and entrances D. Figure 10 is a perspective view showing the detailed configuration of the equipment 100. Figure 11 is a rear view showing the detailed configuration of the equipment 100. The equipment 100 mainly comprises a first member 101, a second member 102A, a second member 102B, a second member 102C, and a filler material 103A. 【0100】 (5-1-1-1) The first member 101 is connected to the upper end 102Cu at its rear end 101b. At all ends of the first member 101, the first interval d1 is not in communication with the outside O. 【0101】 (5-1-1-2) The second member 102A is connected to the left end 102CL at its rear end 102Ab. The second member 102B is connected to the right end 102Cr at its rear end 102Bb. 【0102】 The second member 102C is provided with a second interval d4 between the rear wall 14 and the second member 102C, which is the distance between the rear wall 14 and the second member 102C. The second interval d4 is approximately equal in length across substantially the entire area between the second member 102C and the rear wall 14 where the second interval d4 is formed. The second interval d4 is approximately equal in length to the first interval d1, the second interval d2, and the second interval d3. 【0103】 The second member 102C has a plate-like shape. The second member 102C is provided so as to face more than half of the area of ​​the rear wall 14. The second member 102C has four ends: an upper end 102Cu, a left end 102CL, a right end 102Cr, and a lower end 102Cd. 【0104】The second member 102C is connected to the rear end 101b at its upper end 102Cu. Therefore, the first interval d1 and the second interval d4 are in communication at the upper end 102Cu and the rear end 101b. The second member 102C is connected to the rear end 102Ab at its left end 102CL. The second member 102C is connected to the rear end 102Bb at its right end 102Cr. The second member 102C is not connected to any other components of the equipment 100 at its lower end 102Cd. Therefore, the second interval d4 is in communication with the outside O at its lower end 102Cd. The second interval d4 is in communication with the outside O vertically below the vertical center of the greenhouse 10. 【0105】 Furthermore, a mesh-like member to prevent animals from entering may be provided at the second interval d4 in the lower end portion 102Cd. 【0106】 (5-1-1-3) Filler material Filler material 103A fills the first gap d1 at the front end 101f, excluding the left end 101L where the first gap d1 and the second gap d2 are connected, the right end 101r where the first gap d1 and the second gap d3 are connected, and the rear end 101b where the first gap d1 and the second gap d4 are connected. 【0107】 (5-1-2) Airflow The flow of air A from the interior I1 to the exterior O through the second gap d2 or second gap d3 is the same as in the first embodiment, so the explanation will be omitted. The flow of air A from the interior I1 to the exterior O through the first gap d1 and the second gap d4 will be explained. The air conditioner supplies warmer air A from the exterior O to the interior I1. The ventilation device is driven to circulate air A. Figure 12 is a schematic diagram of the equipment system 1 showing the flow of air A. 【0108】 As the ventilation device is activated, air A flows into the opening V inside I1 (not shown). Air A is drawn into the opening V by the ventilation device (not shown). Air A is blown out by the ventilation device into the first gap d1 between the opening V and the first member 101 (not shown). 【0109】The second interval d4 is in communication with the outside O at its lower end 102Cd. Therefore, the pressure in the second interval d4 is close to the atmospheric pressure of the outside O. The pressure in the first interval d1 is higher than the pressure in the second interval d4. 【0110】 Due to the pressure difference, the air A blown out from the opening V flows towards the lower end 102Cd. The air A blown out from the opening V flows into the first gap d1 at the rear end 101b. 【0111】 The air A that flows through the first gap d1 at the rear end 101b flows to the second gap d4 at the lower end 102Cd. From the second gap d4 at the lower end 102Cd, the air A flows to the outside O. The air A that flows to the outside O is warmer than the outside O. Therefore, the air A that flows to the outside O flows upward from the lower end 102Cd. 【0112】 More than half of the area of ​​the rear wall 14 is enclosed by the air A flowing through the second interval d4. Therefore, the interior I1 is enclosed by the air A flowing through the second interval d4. 【0113】 The second member 102C is enveloped by air A flowing upward from the lower end 102Cd in the external environment O. In other words, more than half of the area of ​​the rear wall 14 is enveloped by air A flowing upward from the lower end 102Cd in the external environment O. Therefore, the interior I1 is enveloped by air A flowing upward from the lower end 102Cd in the external environment O. 【0114】 (5-2) Modification 1B (5-2-1) The structural equipment 100 may further include a second member 102D. The rear wall 14 is not provided with windows and an entrance D. Figure 13 is a perspective view showing the detailed configuration of the equipment 100. Figure 14 is a front view showing the detailed configuration of the equipment 100. The equipment 100 mainly comprises a first member 101, a second member 102A, a second member 102B, a second member 102C, a second member 102D, and a filler material 103C. The following explanation will be omitted for points that are the same as in Modification 1A. 【0115】 (5-2-1-1) The first member 101 is connected to the upper end 102Du at its front end 101f. At all ends of the first member 101, the first interval d1 is not in communication with the outside O. 【0116】 (5-2-1-2) The second member 102A is connected to the left end 102DL at its front end 102Af. The second member 102B is connected to the right end 102Dr at its front end 102Bf. 【0117】 The second member 102D is provided with a second interval d5 between the front wall 11 and the second member 102D, which is the distance between the front wall 11 and the second member 102D. The second interval d5 is approximately equal in length across substantially the entire area between the second member 102D and the front wall 11 where the second interval d5 is formed. The second interval d5 is approximately equal in length to the first interval d1, the second interval d2, the second interval d3, and the second interval d4. 【0118】 The shape of the second member 102D is plate-like. The second member 102D is provided so as to face more than half of the area of ​​the front wall 11. The second member 102D is provided so as not to face the entrance / exit D. The second member 102D has five ends: an upper end 102Du, a left end 102DL, a right end 102Dr, a lower end 102Dd, and a U-shaped end 102Dc. The U-shaped end 102Dc is the end of the second member 102D that is close to the entrance / exit D and is U-shaped. 【0119】 The second member 102D is connected to the front end 101f at its upper end 102Du. Therefore, the first interval d1 and the second interval d5 are in communication at the upper end 102Du and the front end 101f. The second member 102D is connected to the front end 102Af at its left end 102DL. The second member 102D is connected to the front end 102Bf at its right end 102Dr. The second member 102D is not connected to any other components of the equipment 100 at its lower end 102Dd. Therefore, the second interval d5 is in communication with the outside O at its lower end 102Dd. The second interval d5 is in communication with the outside O vertically below the vertical center of the greenhouse 10. The second member 102D is connected to the filler material 103C at its U-shaped end 102Dc. 【0120】 Furthermore, a mesh-like member to prevent animals from entering may be provided at the second interval d5 at the lower end portion 102Dd. 【0121】(5-2-1-3) The filler material 103C fills the second gap d5 at the U-shaped end 102Dc so that the second gap d5 is not in communication with the outside O. 【0122】 The shape of the filler material 103C is elongated and U-shaped. The filler material 103C is pre-processed so that it fits into the second gap d5. The filler material 103C may also be a component formed by later filling the second gap d5 with expanded polystyrene or expanded urethane. 【0123】 (5-2-2) Airflow The flow of air A from the interior I1 to the exterior O through the second gap d2 or second gap d3 is the same as in the first embodiment, so the explanation is omitted. The flow of air A from the interior I1 to the exterior O through the second gap d4 is the same as in Modification 1A, so the explanation is omitted. The flow of air A from the interior I1 to the exterior O through the first gap d1 and the second gap d5 will be explained. The air conditioner supplies warmer air A to the interior I1 than the air outside O. The ventilation device is driven to circulate air A. Figure 15 is a schematic diagram of the equipment system 1 showing the flow of air A. 【0124】 As the ventilation device is activated, air A flows into the opening V inside I1 (not shown). Air A is drawn into the opening V by the ventilation device (not shown). Air A is blown out by the ventilation device into the first gap d1 between the opening V and the first member 101 (not shown). 【0125】 The second interval d5 is connected to the outside O at its lower end 102Dd. Therefore, the atmospheric pressure in the second interval d5 is close to the atmospheric pressure of the outside O. The atmospheric pressure in the first interval d1 is higher than the atmospheric pressure in the second interval d5. 【0126】 Due to the pressure difference, the air A blown out from the opening V flows towards the lower end 102Dd. The air A blown out from the opening V flows into the first gap d1 at the front end 101f. 【0127】The air A that flows through the first gap d1 at the front end 101f flows to the second gap d5 at the lower end 102Dd. From the second gap d5 at the lower end 102Dd, the air A flows out to the outside O. The air A that flows out to the outside O is warmer than the outside O. Therefore, the air A that flows out to the outside O flows upward from the lower end 102Dd. 【0128】 The front wall 11 is surrounded by air A flowing through the second interval d5. Therefore, the interior I1 is surrounded by air A flowing through the second interval d5. 【0129】 The second member 102D is enveloped by air A flowing upward from its lower end 102Dd in the external environment O. In other words, the front wall 11 is enveloped by air A flowing upward from its lower end 102Dd in the external environment O. Therefore, the interior I1 is enveloped by air A flowing upward from its lower end 102Dd in the external environment O. 【0130】 <Second Embodiment> (1) Overall Configuration Hereinafter, explanations of the similarities between the first and second embodiments will be omitted, and the differences between the first and second embodiments will be explained in detail. Figure 16 is a schematic diagram showing the overall configuration of the equipment system 2. The equipment system 2 mainly comprises a livestock shed 20, an air conditioner (not shown), and equipment 200. 【0131】 (1-1) Inside the livestock shed 20, I2, livestock L are raised. Livestock L are chickens, but are not limited to chickens. The detailed configuration of the livestock shed 20 will be described later. 【0132】 The facility system 2 may also include, instead of the livestock barn 20, any of the following: a greenhouse (such as greenhouse 10), a hothouse, a mushroom cultivation facility, a plant factory (such as plant factory 60), a land-based aquaculture farm, a warehouse (such as warehouse 30), a data center (such as data center 40), a commercial building, an industrial building, an agricultural building, or a residential building (such as house 50). 【0133】 (1-2) Air conditioners Air conditioners perform air conditioning of the interior I2. Examples of air conditioning include cooling, heating, ventilation, air purification, dehumidification, and humidification. 【0134】(1-3) Equipment Equipment 200 is equipment that forms an insulating layer with air A flowing from the inside I2 to the outside O of the livestock barn 20. The detailed configuration of equipment 200 will be described later. 【0135】 (2) Detailed configuration (2-1) Figure 17 of the livestock shed is a perspective view showing the detailed configuration of the livestock shed 20. The livestock shed 20 mainly consists of a front wall 21, a left side wall 22, a right side wall 23, a rear wall 24, and a ceiling 25. 【0136】 The front wall 21, the left wall 22, the right wall 23, and the rear wall 24 are vertical walls erected approximately perpendicular to the ground T. The front wall 21, the left wall 22, the right wall 23, the rear wall 24, and the ceiling 25 are components that are in contact with the outside O. 【0137】 An opening V is provided in the center of the left wall 22 and the right wall 23 in the Z direction. The opening V is located vertically above the vertical center of the livestock shed 20. The opening V is an opening through which air A flows from the inside I2 to the outside O. A ventilation device (not shown) is provided in the opening V. The ventilation device is a device that drives air A from the inside I2 to the outside O. 【0138】 The ceiling 25 faces the ground T and is connected to the front wall 21, the left side wall 22, the right side wall 23, and the rear wall 24. The shape of the ceiling 25 is such that it rises in the Y direction from the left and right ends toward the center in the X direction. The shape of the ceiling 25 may be curved or flat. 【0139】 The left wall 22 and the right wall 23 are first components. The first components are components of the livestock shed 20 that are in contact with the outside O and are provided with an opening V. 【0140】 The front wall 21, the rear wall 24, and the ceiling 25 are second components. The second components are components of the livestock shed 20 that are in contact with the outside O and do not have openings V. 【0141】 The area of ​​the ground T opposite the ceiling 25 is enclosed by the front wall 21, the left wall 22, the right wall 23, the rear wall 24, and the ceiling 25, thereby forming the interior I2. 【0142】An entrance / exit D is provided in the front wall 21. Windows and entrance / exit D are not provided in the left wall 22, the right wall 23, or the ceiling 25. 【0143】 (2-2) Figure 18 is a perspective view showing the detailed configuration of equipment 200. Figure 19 is a front view showing the detailed configuration of equipment 200. Figure 20 is a rear view showing the detailed configuration of equipment 200. Figure 21 is a left side view showing the detailed configuration of equipment 200. Figure 22 is a right side view showing the detailed configuration of equipment 200. Figure 23 is a top view showing the detailed configuration of equipment 200. Equipment 200 mainly consists of a first member 201A, a first member 201B, a second member 202, a filler material 203A, and a filler material 203B. 【0144】 (2-2-1) The first member The first member 201A is provided with a first interval d6 between the left side wall 22 and the first member 201A, which is the distance between the left side wall 22 and the first member 201A. The length of the first interval d6 is 2 cm or more and 10 cm or less, but is not limited thereto. The first interval d6 is approximately equal in length over substantially the entire area between the first member 201A and the left side wall 22 where the first interval d6 is formed. 【0145】 The shape of the first member 201A is plate-like. The configuration of the first member 201A is the same as that of the first member 201B. The first member 201A is provided so as to face the opening V and more than half of the area of ​​the left side wall 22. The first member 201A has four ends: an upper end 201Au, a front end 201Af, a rear end 201Ab, and a lower end 201Ad. 【0146】 The first member 201A is connected to the left end 202L at its upper end 201Au. The first member 201A is connected to the filler material 203A at its front end 201Af. The first member 201A is connected to the filler material 203B at its rear end 201Ab. The first member 201A is not connected to any other components of the equipment 200 at its lower end 201Ad. Therefore, the first gap d6 is in communication with the outside O at its lower end 201Ad. The first gap d6 is in communication with the outside O vertically below the vertical center of the livestock shed 20. 【0147】The first member 201B is provided with a first interval d7 between the right side wall 23 and the first member 201B, which is the distance between the right side wall 23 and the first member 201B. The first interval d7 is approximately equal in length across substantially the entire area between the first member 201B and the right side wall 23 where the first interval d7 is formed. The first interval d7 is approximately equal in length to the first interval d6. 【0148】 The first member 201B has a plate-like shape. The first member 201B is provided so as to face the opening V and more than half of the area of ​​the right side wall 23. The first member 201B has four ends: an upper end 201Bu, a front end 201Bf, a rear end 201Bb, and a lower end 201Bd. 【0149】 The first member 201B is connected to the right end 202r at its upper end 201Bu. The first member 201B is connected to the filler material 203A at its front end 201Bf. The first member 201B is connected to the filler material 203B at its rear end 201Bb. The first member 201B is not connected to any other components of the equipment 200 at its lower end 201Bd. Therefore, the first gap d7 is in communication with the outside O at its lower end 201Bd. The first gap d7 is in communication with the outside O vertically below the vertical center of the livestock shed 20. 【0150】 Furthermore, a mesh-like member to prevent animals from entering may be provided at the first interval d6 and the first interval d7 at the lower end portion 201Bd. 【0151】 (2-2-2) The second member The second member 202 is a member provided with a second interval d8 between the ceiling 15 and the second member 202, which is the distance between the ceiling 15 and the second member 202. The second interval d8 is approximately equal in length across substantially the entire area between the second member 202 and the ceiling 15 where the second interval d8 is formed. The second interval d8 is approximately equal in length to the first interval d6 and the first interval d7. 【0152】 The second member 202 has four ends: a left end 202L, a right end 202r, a front end 202f, and a rear end 202b. 【0153】The second member 202 is connected to the upper end 201Au at its left end 202L. Therefore, the first interval d6 and the second interval d8 are in communication at both the left end 202L and the upper end 201Au. The second member 202 is connected to the upper end 201Bu at its right end 202r. Therefore, the first interval d7 and the second interval d8 are in communication at both the right end 202r and the upper end 201Bu. The second member 202 is connected to the filler material 203A at its front end 202f. The second member 202 is connected to the filler material 203B at its rear end 202b. At all ends of the second member 202, the second interval d8 is not in communication with the outside O. 【0154】 The shape of the second member 202 is such that it rises in the Y direction from the left end 202L and the right end 202r toward the center in the X direction. The second member 202 is installed so as to face substantially the entire area of ​​the ceiling 15. 【0155】 (2-3) Filler The filler material 203A fills the first gap d6 at the front end 201Af so that the first gap d6 is not in communication with the outside O. The filler material 203A fills the first gap d7 at the front end 201Bf so that the first gap d7 is not in communication with the outside O. The filler material 203A fills the second gap d8 at the front end 202f so that the second gap d8 is not in communication with the outside O. 【0156】 The filler material 203B fills the first gap d6 at the rear end 201Ab so that the first gap d6 is not in communication with the outside O. The filler material 203B fills the first gap d7 at the rear end 201Bb so that the first gap d7 is not in communication with the outside O. The filler material 203B fills the second gap d8 at the rear end 202b so that the second gap d8 is not in communication with the outside O. 【0157】 The shape of the filler material 203A and filler material 203B is elongated and U-shaped. The filler material 203A and filler material 203B are pre-processed so that they can be fitted into the first interval d6, the first interval d7, and the second interval d8. Alternatively, the filler material 203A and filler material 203B may be formed by later filling the first interval d6, the first interval d7, and the second interval d8 with expanded polystyrene or expanded urethane, etc. 【0158】 (3) Airflow The flow of air A from the interior I2 will be explained. The air conditioner supplies warmer air A from the outside O to the interior I2. The ventilation device is driven to circulate air A. Figure 24 is a schematic diagram of the equipment system 2 showing the flow of air A. 【0159】 As the ventilation device is activated, air A flows into the opening V inside I2 (not shown). Air A is drawn into the opening V by the ventilation device (not shown). Air A is blown out by the ventilation device into the first gap d6 between the opening V and the first member 201A and the first gap d7 between the opening V and the first member 201B (not shown). 【0160】 The first gap d6 is connected to the outside environment O of atmospheric pressure at the lower end 201Ad. The first gap d7 is connected to the outside environment O of atmospheric pressure at the lower end 201Bd. Therefore, the air A blown out from the opening V flows through the first gap d6 at the lower end 201Ad and the first gap d7 at the lower end 201Bd. 【0161】 At the lower end 201Ad, air A flows from the first gap d6 to the outside O. Also, at the lower end 201Bd, air A flows from the first gap d7 to the outside O. The air A that flows to the outside O is warmer than the outside O. The air A that flows to the outside O flows upward from the lower end 201Ad or the lower end 201Bd in the outside O. 【0162】 The second member 202 does not face the opening V. The air pressure at the second interval d8 is lower than the air pressure at the first intervals d6 and d7 from which air A is blown out of the opening V. Therefore, the air A blown out of the opening V flows from the first interval d6 to the second interval d8, and also flows from the first interval d7 to the second interval d8. 【0163】The air A flowing from the first interval d6 to the second interval d8 and the air A flowing from the first interval d7 to the second interval d8 collide near the center of the second member 202 in the X direction. Because the air A collides and is compressed, the air pressure at the second interval d8 near the center of the second member 202 in the X direction becomes higher. The air pressure at the second interval d8 near the center of the second member 202 in the X direction is higher than the air pressure at the second interval d8 at the left end 202L and the right end 202r. Therefore, the air A near the center of the second member 202 in the X direction flows to the second interval d8 at the left end 202L and the right end 202r. 【0164】 The air A that flows through the second interval d8 at the left end 202L flows through the first interval d6 at the lower end 201Ad. The air A that flows through the second interval d8 at the right end 202r flows through the first interval d7 at the lower end 201Bd. At the lower end 201Ad, the air A flows from the first interval d6 to the outside O. Also at the lower end 201Bd, the air A flows from the first interval d7 to the outside O. The air A that flows to the outside O is warmer than the outside O. The air A that flows to the outside O flows upward from the lower end 201Ad or the lower end 201Bd at the outside O. 【0165】 More than half of the left wall 22 is enveloped by air A flowing through the first interval d6. More than half of the right wall 23 is enveloped by air A flowing through the first interval d7. Almost the entire ceiling 25 is enveloped by air A flowing through the second interval d8. Therefore, the interior I2 is enveloped by air A flowing through the first interval d6, the first interval d7, and the second interval d8. 【0166】 The first member 201A is enveloped by air A flowing upward from its lower end 201Ad in the outside O. In other words, more than half of the area of ​​the left wall 22 is enveloped by air A flowing upward from its lower end 201Ad in the outside O. The first member 201B is enveloped by air A flowing upward from its lower end 201Bd in the outside O. In other words, more than half of the area of ​​the right wall 23 is enveloped by air A flowing upward from its lower end 201Bd in the outside O. Therefore, the interior I2 is enveloped by air A flowing upward from its lower end 201Ad in the outside O and air A flowing upward from its lower end 201Bd in the outside O. 【0167】 (4) Features (4-1) The opening V of the equipment 200 is located approximately vertically above the approximate vertical center of the structure. The first interval d6 and the first interval d7 are in communication with the outside O, located approximately vertically below the approximate vertical center of the structure. 【0168】 Air A flows from vertically above where the opening V is provided, and vertically downward where it communicates with the outside O. Air A flows widely at the first intervals d6 and d7, forming a wide insulating layer. Therefore, the equipment 200 can achieve energy savings in the interior I2 of the livestock barn 20. 【0169】 The first intervals d6 and d7 communicate with the outside O vertically below the vertical center of the barn 20. When the interior I2 is heated, the air A flowing to the outside O is warmer than the outside O. The air A that flows to the outside O rises. The air A flowing upwards envelops the barn 20 from the outside of the first member 201A or the first member 201B. The equipment 200 can form a double insulation layer on the left wall 22 and the right wall 23. Therefore, the equipment 200 can achieve energy savings on the interior I2 of the barn 20. 【0170】 (5) Modifications: The following descriptions will omit explanations of points similar to those in the second embodiment and will focus on the differences from the second embodiment. 【0171】 (5-1) Modification 2A (5-1-1) The structural equipment 200 may further include a first member 201C. An opening V is provided in the rear wall 24. Figure 25 is a perspective view showing the detailed configuration of the livestock shed 20. Figure 26 is a perspective view showing the detailed configuration of the equipment 200. Figure 27 is a rear view showing the detailed configuration of the equipment 200. The equipment 200 mainly comprises a first member 201A, a first member 201B, a first member 201C, a second member 202, and a filler material 203A. 【0172】 (5-1-1-1) The first member 201A is connected to the left end 201CL at its rear end 201Ab. The first member 201B is connected to the right end 201Cr at its rear end 201Bb. 【0173】The first member 201C is provided with a first interval d9 between the rear wall 24 and the first member 201C, which is the distance between the rear wall 24 and the first member 201C. The first interval d9 is approximately equal in length across substantially the entire area between the first member 201C and the rear wall 24 where the first interval d9 is formed. The first interval d9 is approximately equal in length to the first interval d6, the first interval d7, and the second interval d8. 【0174】 The first member 201C has a plate-like shape. The first member 201C is provided so as to face the opening V and more than half of the area of ​​the rear wall 24. The first member 201C has four ends: an upper end 201Cu, a left end 201CL, a right end 201Cr, and a lower end 201Cd. 【0175】 The first member 201C is connected to the rear end 202b at its upper end 201Cu. The first member 201C is connected to the rear end 201Ab at its left end 201CL. The first member 201C is connected to the rear end 201Bb at its right end 201Cr. The first member 201C is not connected to any other components of the equipment 200 at its lower end 201Cd. Therefore, the first gap d9 is in communication with the outside O at its lower end 201Cd. The first gap d9 is in communication with the outside O vertically below the vertical center of the livestock shed 20. 【0176】 Furthermore, a mesh-like member to prevent animals from entering may be provided at the first interval d9 in the lower end portion 201Cd. 【0177】 (5-1-1-2) The second member 202 is connected to the upper end 201Cu at its rear end 202b. Therefore, the first interval d9 and the second interval d8 are in communication at the rear end 202b and the upper end 201Cu. At all ends of the second member 202, the second interval d8 is not in communication with the outside O. 【0178】(5-1-2) Airflow The flow of air A from the interior I2 to the exterior O through the first gap d6 or the first gap d7 is the same as in the second embodiment, so the explanation is omitted. The flow of air A from the interior I2 to the exterior O through the first gap d9 will be explained. The air conditioner supplies warmer air A to the interior I2 than the air outside O. The ventilation device is driven to circulate air A. Figure 28 is a schematic diagram of the equipment system 2 showing the flow of air A. 【0179】 As the ventilation device is activated, air A flows into the opening V inside I2 (not shown). Air A is drawn into the opening V by the ventilation device (not shown). Air A is blown out by the ventilation device into the first gap d9 between the opening V and the first member 201C (not shown). 【0180】 The first gap d9 is connected to the outside air O at atmospheric pressure at the lower end 201Cd. Therefore, the air A blown out from the opening V flows into the first gap d9 at the lower end 201Cd. At the lower end 201Cd, the air A flows from the first gap d9 to the outside air O. The air A that flows to the outside air O is warmer than the outside air O. The air A that flows to the outside air O flows upward from the lower end 201Cd. 【0181】 The atmospheric pressure at the second interval d8 is lower than the atmospheric pressure at the first interval d9, from which air A is blown out of the opening V. Therefore, air A blown out of the opening V also flows from the first interval d9 to the second interval d8. 【0182】 Air A flowing from the first interval d9 to the second interval d8 collides with other air A near the center of the second member 202 in the Z direction. Because the air A collides and is compressed, the air pressure at the second interval d8 near the center of the second member 202 in the Z direction becomes higher. The air pressure at the second interval d8 near the center of the second member 202 in the Z direction is higher than the air pressure at the second interval d8 at the rear end 202b. Therefore, the air A near the center of the second member 202 in the Z direction flows to the second interval d8 at the rear end 202b. 【0183】At the rear end 202b, the air A that flows through the second gap d8 flows through the first gap d9 at the lower end 201Cd. At the lower end 201Cd, the air A flows from the first gap d9 to the outside O. The air A that flows to the outside O is warmer than the outside O. At the outside O, the air A that has flowed to the outside O flows upward from the lower end 201Cd. 【0184】 More than half of the area of ​​the rear wall 24 is enclosed by the air A flowing through the first interval d9. Therefore, the interior I2 is enclosed by the air A flowing through the first interval d9. 【0185】 The first member 201C is enveloped by air A flowing upward from the lower end 201Cd in the external environment O. In other words, more than half of the area of ​​the rear wall 24 is enveloped by air A flowing upward from the lower end 201Cd in the external environment O. Therefore, the interior I2 is enveloped by air A flowing upward from the lower end 201Cd in the external environment O. 【0186】 (5-2) Modification 1B (5-2-1) The structural equipment 200 may further include a first member 201D. An opening V is further provided in the front wall 21. Figure 29 is a perspective view showing the detailed configuration of the livestock shed 20. Figure 30 is a perspective view showing the detailed configuration of the equipment 200. Figure 31 is a front view showing the detailed configuration of the equipment 200. The equipment 200 mainly includes a first member 201A, a first member 201B, a first member 201C, a first member 201D, a second member 202, and a filler material 203C. The following explanation will be omitted for points that are the same as in Modification 2A. 【0187】 (5-2-1-1) The first member, the first member 201A, is connected to the left end 201DL at its front end 201Af. The first member 201B is connected to the right end 201Dr at its front end 201Bf. 【0188】 The first member 201D is provided with a first interval d10, which is the distance between the front wall 21 and the first member 201D, from the front wall 21. The first interval d10 is approximately equal in length across substantially the entire area between the first member 201D and the front wall 21 where the first interval d10 is formed. The first interval d10 is approximately equal in length to the first interval d6, the first interval d7, the first interval d9, and the second interval d8. 【0189】 The first member 201D is plate-shaped. The first member 201C is provided so as to face the opening V and the front wall 21. The first member 201D has five ends: an upper end 201Du, a left end 201DL, a right end 201Dr, a lower end 201Dd, and a U-shaped end 201Dc. The U-shaped end 201Dc is the end of the first member 201D that is close to the entrance / exit D and is U-shaped. 【0190】 The first member 201D is connected to the front end 202f at its upper end 201Du. The first member 201D is connected to the front end 201Af at its left end 201DL. The first member 201D is connected to the front end 201Bf at its right end 201Dr. The first member 201D is not connected to any other components of the equipment 200 at its lower end 201Dd. Therefore, the first gap d10 is in communication with the outside O at its lower end 201Dd. The first gap d10 is in communication with the outside O vertically below the vertical center of the livestock shed 20. The first member 201D is connected to the filler material 203C at its U-shaped end 201Dc. 【0191】 Furthermore, a mesh-like member to prevent animals from entering may be provided at the first interval d10 at the lower end portion 201Dd. 【0192】 (5-2-1-2) The second member 202 is connected to the upper end 201Du at its front end 202f. Therefore, the first interval d10 and the second interval d8 are in communication at the front end 202f and the upper end 201Du. At all ends of the second member 202, the second interval d8 is not in communication with the outside O. 【0193】 (5-2-1-3) The filler material 203C fills the first gap d10 at the U-shaped end 201Dc so that the first gap d10 is not in communication with the outside O. 【0194】 The shape of the filler material 203C is elongated and U-shaped. The filler material 203C is pre-processed so that it fits into the first gap d10. The filler material 203C may also be a component formed by later filling the first gap d10 with expanded polystyrene or expanded urethane. 【0195】 (5-2-2) Airflow The flow of air A from the interior I2 to the exterior O through the first gap d6 or the first gap d7 is the same as in the second embodiment, so the explanation is omitted. The flow of air A from the interior I2 to the exterior O through the first gap d9 is the same as in Modification 2A, so the explanation is omitted. The flow of air A from the interior I2 to the exterior O through the first gap d10 will be explained. The air conditioner supplies warmer air A to the interior I2 than the air outside O. The ventilation device is driven to circulate air A. Figure 32 is a schematic diagram of the equipment system 2 showing the flow of air A. 【0196】 As the ventilation device is activated, air A flows into the opening V inside I2 (not shown). Air A is drawn into the opening V by the ventilation device (not shown). Air A is blown out by the ventilation device into the first gap d10 between the opening V and the first member 201D (not shown). 【0197】 The first gap d10 is connected to the outside O, which is at atmospheric pressure, at the lower end 201Dd. Therefore, the air A blown out from the opening V flows into the first gap d10 at the lower end 201Dd. At the lower end 201Dd, the air A flows from the first gap d10 to the outside O. The air A that flows to the outside O is warmer than the outside O. The air A that flows to the outside O flows upward from the lower end 201Dd. 【0198】 The front wall 21 is surrounded by air A flowing through the first interval d10. Therefore, the interior I2 is surrounded by air A flowing through the first interval d10. 【0199】 The first member 201D is enveloped by air A flowing upward from its lower end 201Dd in the external environment O. In other words, the front wall 21 is enveloped by air A flowing upward from its lower end 201Dd in the external environment O. Therefore, the interior I2 is enveloped by air A flowing upward from its lower end 201Dd in the external environment O. 【0200】<Third Embodiment> (1) Overall Configuration Hereinafter, we will omit explanations of the similarities between the first and third embodiments and will focus on explaining the differences between the first and third embodiments.

The second member 302 is not connected to other components of the equipment 300 at its front end 302f and rear end 302b. Therefore, the second interval d13 is in communication with the outside O at the front end 302f and rear end 302b. The second interval d13 is in communication with the outside O vertically above the vertical center of the warehouse 30. 【0223】 Furthermore, a mesh-like member to prevent animals from entering may be provided in the second gap d13 between the front end 302f and the rear end 302b. 【0224】 (2-3) Filler material Filler material 303A fills the first gap d11 at the front end 301Af so that the first gap d11 is not in communication with the outside O. Filler material 303B fills the first gap d11 at the rear end 301Ab so that the first gap d11 is not in communication with the outside O. 【0225】 The filler material 303C fills the first gap d12 at the front end 301Bf so that the first gap d12 does not communicate with the outside O. The filler material 303D fills the first gap d12 at the rear end 301Bb so that the first gap d12 does not communicate with the outside O. 【0226】 The filler materials 303A, 303B, 303C, and 303D are elongated in shape. Filler materials 303A and 303B are pre-processed so as to fit into the first gap d11. Filler materials 303C and 303D are pre-processed so as to fit into the first gap d12. Filler materials 303A and 303B may be formed by later filling the first gap d11 with expanded polystyrene or polyurethane foam. Filler materials 303C and 303D may be formed by later filling the first gap d12 with expanded polystyrene or polyurethane foam. 【0227】 The equipment 300 may further include a filler material (not shown) to fill the second gap d13 at the rear end 302b or the second gap d13 at the front end 302f. In this case, the second gap d13 at the rear end 302b or the front end 302f is not in communication with the outside O. 【0228】 (3) The flow of air A from the interior I3 in the airflow equipment system 3 will be explained. The air conditioner supplies air A, which is colder than the outside O, to the interior I3. The ventilation device is driven to circulate air A. Figure 41 is a schematic diagram of the equipment system 3 showing the flow of air A. 【0229】 As the ventilation device is activated, air A flows into the opening V inside I3 (not shown). Air A is drawn into the opening V by the ventilation device (not shown). Air A is blown out by the ventilation device into the first gap d11 between the opening V and the first member 301A and the first gap d12 between the opening V and the first member 301B (not shown). 【0230】 The second interval d13 is in communication with the outside O at its front end 302f and rear end 302b. Therefore, the air pressure in the second interval d13 is close to the atmospheric pressure of the outside O. On the other hand, the air pressure in the first intervals d11 and d12 is higher than atmospheric pressure because air A is blown out from the opening V. The air pressure in the first intervals d11 and d12 is higher than the air pressure in the second interval d13. 【0231】 Therefore, the air A blown out from the opening V flows to the first gap d11 at the upper end 301Au and the first gap d12 at the upper end 301Bu. The air A that flows to the first gap d11 at the upper end 301Au flows to the second gap d13 at the left end 302L. The air A that flows to the first gap d12 at the upper end 301Bu flows to the second gap d13 at the right end 302r. The air A flowing from the second gap d13 at the left end 302L and the air A flowing from the second gap d13 at the right end 302r collide at the second gap d13 near the center of the second member 302 in the X direction. 【0232】Air A that collides with the second gap d13 near the center in the X direction of the second member 302 flows to the second gap d13 at the front end 302f or the rear end 302b. Air A flows from the second gap d13 at the front end 302f or the rear end 302b to the outside O. Air A that flows to the outside O is colder than the outside O. Therefore, the air A that flows to the outside O flows downward from the front end 302f and the rear end 302b. 【0233】 Almost the entire area of ​​the left wall 32 is enveloped by air A flowing through the first interval d11. Almost the entire area of ​​the right wall 33 is enveloped by air A flowing through the first interval d12. Almost the entire area of ​​the ceiling 35 is enveloped by air A flowing through the second interval d13. Therefore, the interior I3 is enveloped by air A flowing through the first interval d11, the first interval d12, and the second interval d13. 【0234】 The front wall 31 is surrounded by air A flowing downward from the front end 302f in the outside O. The rear wall 34 is surrounded by air A flowing downward from the rear end 302b in the outside O. Therefore, the interior I3 is surrounded by air A flowing downward from the front end 302f in the outside O and air A flowing downward from the rear end 302b in the outside O. 【0235】 (4) The characteristic equipment 300 has an opening V located approximately vertically below the approximate vertical center of the structure. The second interval d13 is located approximately vertically above the approximate vertical center of the structure and communicates with the outside O. 【0236】 Air A flows from vertically below where the opening V is provided, vertically upward where it communicates with the outside O. Air A flows widely in the first interval d11, the first interval d12, and the second interval d13, forming a wide insulating layer. Therefore, the equipment 300 can achieve energy savings in the interior I3 of the warehouse 30. 【0237】The second interval d13 communicates with the outside O vertically above the vertical center of the warehouse 30. When the interior I3 is cooled, the air A flowing to the outside O is colder than the outside O. The air A that flows to the outside O flows downwards. The downward-flowing air A envelops the warehouse 30 from the outside of the front wall 31 and the rear wall 34. The equipment 300 can also form an insulating layer on the front wall 31 and the rear wall 34. Therefore, the equipment 300 can achieve energy savings on the interior I3 of the warehouse 30. 【0238】 (5) Modifications: The following descriptions will focus on the differences from the third embodiment, omitting explanations of points similar to those in the third embodiment. 【0239】 (5-1) Modification 3A (5-1-1) The structural equipment 300 may further include a first member 301C. An opening V is provided in the rear wall 34. Figure 42 is a perspective view showing the detailed configuration of the warehouse 30. Figure 43 is a perspective view showing the detailed configuration of the equipment 300. Figure 44 is a rear view showing the detailed configuration of the equipment 300. The equipment 300 mainly comprises a first member 301A, a first member 301B, a first member 301C, a second member 302, a filler material 303A, and a filler material 303C. 【0240】 (5-1-1-1) The first member 301A is connected to the left end 301CL at its rear end 301Ab. The first member 301B is connected to the right end 301Cr at its rear end 301Bb. 【0241】 The first member 301C is provided with a first interval d14 between the rear wall 34 and the first member 301C, which is the distance between the rear wall 34 and the first member 301C. The first interval d14 is approximately equally spaced throughout substantially the entire area between the first member 301C and the rear wall 34 where the first interval d14 is formed. The first interval d14 is approximately equally spaced with the first interval d11, the first interval d12, and the second interval d13. 【0242】 The first member 301C has a plate-like shape. The first member 301C is provided so as to face the opening V and substantially the entire area of ​​the rear wall 34. The first member 301C has four ends: an upper end 301Cu, a left end 301CL, a right end 301Cr, and a lower end 301Cd. 【0243】The first member 301C is connected to the rear end 302b at its upper end 301Cu. The first member 301C is connected to the rear end 301Ab at its left end 301CL. The first member 301C is connected to the rear end 301Bb at its right end 301Cr. The first member 301C is in contact with the ground T at its lower end 301Cd. At all ends of the first member 301C, the first gap d14 is not in communication with the outside O. 【0244】 (5-1-1-2) The second member 302 is connected to the upper end 301Cu at its rear end 302b. Therefore, the first interval d14 and the second interval d13 are in communication at the rear end 302b and the upper end 301Cu. 【0245】 (5-1-2) The flow of air A from the interior I3 in the airflow equipment system 3 will be described below. Points that are the same as the airflow of air A in the third embodiment will be omitted from the explanation. The air conditioner supplies cool air A from the outside O to the interior I3. The ventilation device is driven to circulate air A. Figure 45 is a schematic diagram of the equipment system 3 showing the flow of air A. 【0246】 As the ventilation device is activated, air A flows into the opening V inside I3 (not shown). Air A is drawn into the opening V by the ventilation device (not shown). Air A is blown out by the ventilation device into the first gap d14 between the opening V and the first member 301C, etc. (not shown). 【0247】 The second interval d13 is in communication with the outside O at the front end 302f. Therefore, the pressure in the second interval d13 is close to the atmospheric pressure of the outside O. The pressure in the first interval d14 is higher than the pressure in the second interval d13. 【0248】 The air A blown out from the opening V flows to the first gap d14 at the upper end portion 301Cu. The air A that has flowed to the first gap d14 at the upper end portion 301Cu flows to the second gap d13 at the rear end portion 302b. The air A flowing from the second gap d13 at the rear end portion 302b collides with other air A at the second gap d13 near the center of the second member 302 in the X and Z directions. 【0249】Air A that collides with the second gap d13 near the center of the second member 302 in the X and Z directions flows to the second gap d13 at the front end 302f. Air A then flows from the second gap d13 at the front end 302f to the outside O. Air A that flows to the outside O is colder than the outside O. Therefore, the air A that flows to the outside O flows downward from the front end 302f at the outside O. 【0250】 Almost the entire area of ​​the left wall 32 is enveloped by air A flowing through the first interval d11. Almost the entire area of ​​the right wall 33 is enveloped by air A flowing through the first interval d12. Almost the entire area of ​​the ceiling 35 is enveloped by air A flowing through the second interval d13. Almost the entire area of ​​the rear wall 34 is enveloped by air A flowing through the first interval d14. Therefore, the interior I3 is enveloped by air A flowing through the first interval d11, the first interval d12, the second interval d13, and the first interval d14. 【0251】 The front wall 31 is surrounded by air A flowing downward from the front end 302f in the outside O. Therefore, the interior I3 is surrounded by air A flowing downward from the front end 302f in the outside O. 【0252】 (5-2) Modification 1B (5-2-1) The structural equipment 300 does not need to include the second member 302. Figure 46 is a perspective view showing the detailed configuration of the equipment 300. The equipment 300 mainly comprises a first member 301A, a first member 301B, a filler material 303A, a filler material 303B, a filler material 303C, and a filler material 303D. 【0253】 (5-2-1-1) The first member 301A is not connected to any other components of the equipment 300 at its upper end 301Au. Therefore, the first interval d11 is in communication with the outside O at its upper end 301Au. The first interval d11 is in communication with the outside O vertically above the vertical center of the warehouse 30. 【0254】 The first member 301B is not connected to any other components of the equipment 300 at its upper end 301Bu. Therefore, the first gap d12 is in communication with the outside O at its upper end 301Bu. The first gap d12 is in communication with the outside O vertically above the vertical center of the warehouse 30. 【0255】Furthermore, a mesh-like member to prevent animals from entering may be provided at the first interval d11 at the upper end portion 301Au and at the first interval d12 at the upper end portion 301Bu. 【0256】 The equipment 300 may further include the first member 301C of the modified example 3A. In this case, the equipment 300 mainly comprises the first member 301A, the first member 301B, the first member 301C, the filler material 303A, and the filler material 303C. 【0257】 (5-2-2) The flow of air A from the interior I3 in the airflow equipment system 3 will be explained. The air conditioner supplies cool air A from the outside O to the interior I3. The ventilation device is driven to circulate air A. Figure 47 is a schematic diagram of the equipment system 3 showing the flow of air A. 【0258】 As the ventilation device is activated, air A flows into the opening V inside I3 (not shown). Air A is drawn into the opening V by the ventilation device (not shown). Air A is blown out by the ventilation device into the first gap d11 between the opening V and the first member 301A and the first gap d12 between the opening V and the first member 301B (not shown). 【0259】 The air pressure at the first interval d11 at the upper end 301Au and the air pressure at the first interval d12 at the upper end 301Bu are close to atmospheric pressure because they are in communication with the outside O. Therefore, the air A blown out from the opening V flows to the first interval d11 at the upper end 301Au and to the first interval d12 at the upper end 301Bu. 【0260】 Air A flows to the outside O from the first gap d11 at the upper end 301Au and the first gap d12 at the upper end 301Bu. The air A that flows to the outside O is colder than the outside O. Therefore, the air A that flows to the outside O flows downward from the upper end 301Au or the upper end 301Bu in the outside O. 【0261】 Almost the entire area of ​​the left wall 32 is enclosed by air A flowing through the first interval d11. Almost the entire area of ​​the right wall 33 is enclosed by air A flowing through the first interval d12. Therefore, the interior I3 is enclosed by air A flowing through the first interval d11 and the first interval d12. 【0262】 The left wall 32 is surrounded by air A flowing downward from its upper end 301Au in the outside O. The right wall 33 is surrounded by air A flowing downward from its upper end 301Bu in the outside O. Therefore, the interior I3 is surrounded by air A flowing downward from both its upper end 301Au and its upper end 301Bu in the outside O. 【0263】 (5-2-3) The characteristic equipment 300 has an opening V located approximately vertically below the approximate vertical center of the structure. The first interval d11 and the first interval d12 communicate with the outside O approximately vertically above the approximate vertical center of the structure. 【0264】 Air A flows from vertically below where the opening V is provided, and vertically upward where it communicates with the outside O. Air A flows widely at the first intervals d11 and d12, forming a wide insulating layer. Therefore, the equipment 300 can achieve energy savings in the interior I3 of the warehouse 30. 【0265】 The first intervals d11 and d12 communicate with the outside O vertically above the vertical center of the warehouse 30. When the interior I3 is cooled, the air A flowing to the outside O is colder than the outside O. The air A that flows to the outside O flows downwards. The downward-flowing air A envelops the warehouse 30 from the outside of the left wall 32 and the right wall 33. The equipment 300 can form a double insulation layer around the left wall 32 and the right wall 33. Therefore, the equipment 300 can achieve energy savings in the interior I3 of the warehouse 30. 【0266】 <Fourth Embodiment> (1) Overall Configuration Hereinafter, explanations of the similarities between the first and fourth embodiments will be omitted, and the differences between the first and fourth embodiments will be explained in detail. Figure 48 is a schematic diagram showing the overall configuration of the equipment system 4. The equipment system 4 mainly comprises a data center 40, an air conditioner (not shown), and equipment 400. 【0267】 (1-1) Data Center Servers S are installed in internal I4 on the first floor of data center 40 and internal I5 on the second floor of data center 40. The detailed configuration of data center 40 will be described later. 【0268】The facility system 4 may also include, instead of the data center 40, any of the following: a greenhouse (such as greenhouse 10), a hothouse, a mushroom cultivation facility, a plant factory (such as plant factory 60), a land-based aquaculture farm, a livestock barn (such as livestock barn 20), a warehouse (such as warehouse 30), a commercial building, an industrial building, an agricultural building, or a residential building (such as house 50). 【0269】 (1-2) Air conditioners Air conditioners provide air conditioning for internal I4 and internal I5. Examples of air conditioning include cooling, heating, ventilation, air purification, dehumidification, and humidification. 【0270】 (1-3) Equipment Equipment 400 is equipment that forms an insulating layer with air A flowing from the interior I4 and interior I5 to the exterior O of the data center 40. The detailed configuration of equipment 400 will be described later. 【0271】 (2) Detailed Configuration (2-1) Data Center Figure 49 is a perspective view showing the detailed configuration of the data center 40. The data center 40 mainly consists of a front wall 41, a left side wall 42, a right side wall 43, a rear wall 44, and a ceiling 45. 【0272】 The front wall 41, the left wall 42, the right wall 43, and the rear wall 44 are vertical walls erected approximately perpendicular to the floor surface F. The front wall 41, the left wall 42, the right wall 43, the rear wall 44, and the ceiling 45 are components that are in contact with the outside O. 【0273】 The right wall 43 does not have windows or an entrance / exit D. Multiple openings V are provided vertically below the vertical center of the right wall 43. In other words, the openings V are provided vertically below the vertical center of the data center 40. The openings V are openings through which air A flows from the interior I4 to the exterior O. Ventilation devices (not shown) are provided in the openings V. The ventilation devices are devices that, by drive, flow air A from the interior I4 to the exterior O. 【0274】 The opening V is connected on the side of the interior I4 to a duct (not shown) that communicates with interiors I4 and I5. Therefore, the air A flowing through the opening V is air from interiors I4 and I5. 【0275】The ceiling 45 is approximately parallel to the floor surface F and is connected to the front wall 41, the left side wall 42, the right side wall 43, and the rear wall 44. 【0276】 The right side wall 43 is a first component. The first component is a component of the data center 40 that is in contact with the outside O and is provided with an opening V. 【0277】 The front wall 41, the left side wall 42, the rear wall 44, and the ceiling 45 are second components. The second components are components of the data center 40 that are in contact with the outside O and do not have an opening V. 【0278】 The area of ​​the floor surface F is enclosed by the front wall 41, the left side wall 42, the right side wall 43, the rear wall 44, and the ceiling 45, thereby forming interiors I4 and I5. 【0279】 (2-2) Figure 50 is a perspective view showing the detailed configuration of the equipment 400. Figure 51 is a front view showing the detailed configuration of the equipment 400. Figure 52 is a rear view showing the detailed configuration of the equipment 400. Figure 53 is a left side view showing the detailed configuration of the equipment 400. Figure 54 is a right side view showing the detailed configuration of the equipment 400. Figure 55 is a top view showing the detailed configuration of the equipment 400. The equipment 400 mainly consists of a first member 401, a filler material 403A, and a filler material 403B. 【0280】 (2-2-1) The first member 401 is a member provided with a first interval d15 between the right side wall 43 and the first member 401, from the right side wall 43. The length of the first interval d15 is 2 cm or more and 10 cm or less, but is not limited thereto. The first interval d15 is approximately equal in length over substantially the entire area between the first member 401 and the right side wall 43 where the first interval d15 is formed. 【0281】 The first member 401 has a plate-like shape. The first member 401 is provided so as to face the opening V and substantially the entire area of ​​the right side wall 43. The first member 401 has four ends: a front end 401f, a rear end 401b, a lower end 401d, and an upper end 401u. 【0282】The first member 401 is connected to the filler material 403A at its front end 401f. The first member 401 is connected to the filler material 403B at its rear end 401b. The first member 401 is in contact with the ground T at its lower end 401d. The first member 401 is not connected to any other components of the equipment 400 at its upper end 401u. Therefore, the first gap d15 is in communication with the outside O at its upper end 401u. The first gap d15 is in communication with the outside O vertically above the vertical center of the data center 40. 【0283】 Furthermore, a mesh-like member to prevent animals from entering may be provided at the first interval d15 in the upper end portion 401u. 【0284】 (2-2-2) Filler material 403A fills the first gap d15 at the front end 401f so that the first gap d15 is not in communication with the outside O. Filler material 403B fills the first gap d15 at the rear end 401b so that the first gap d15 is not in communication with the outside O. 【0285】 The filler material 403A and filler material 303B have an elongated shape. Filler material 403A and filler material 403B are pre-processed so that they can be fitted into the first gap d15. However, filler material 403A and filler material 403B may also be formed by later filling the first gap d15 with expanded polystyrene or expanded urethane, etc. 【0286】 Of the four ends of the first member 401, the end furthest from the opening V is the upper end 401u. Filler material 403A fills the first gap d15 at the front end 401f. Filler material 403B fills the first gap d15 at the rear end 401b. The ground T prevents the first gap d15 at the lower end 401d from communicating with the outside O. Therefore, filler materials 403A and 403B prevent the first gap d15 at all ends of the first member 401 except the upper end 401u, which is furthest from the opening V, from communicating with the outside O. 【0287】 Furthermore, the equipment system 3 may also include equipment in a configuration similar to that of equipment 300, positioned to face at least one of the left wall 42 and the rear wall 44. 【0288】 (3) The flow of air A from interior I4 and interior I5 in the airflow equipment system 4 will be explained. The air conditioner supplies air A that is colder than the outside O to interior I4 and interior I5. The ventilation device is driven to circulate air A. Figure 56 is a schematic diagram of the equipment system 4 showing the flow of air A. 【0289】 As the ventilation device is activated, air A flows through the duct to the opening V in interiors I4 and I5 (not shown). Air A is drawn into the opening V from the duct by the ventilation device (not shown). Air A is blown out by the ventilation device into the first gap d15 between the opening V and the first member 401 (not shown). 【0290】 The air pressure at the first interval d15 at the upper end portion 401u is close to atmospheric pressure because it is in communication with the outside O. Therefore, the air A blown out from the opening V flows into the first interval d15 at the upper end portion 401Au. The air A flows from the first interval d15 at the upper end portion 401Au to the outside O. The air A that flows to the outside O is colder than the outside O. Therefore, the air A that flows to the outside O flows downward from the upper end portion 401Au. 【0291】 Almost the entire area of ​​the right wall 43 is enveloped by the air A flowing through the first interval d15. Therefore, the interiors I4 and I5 are enveloped by the air A flowing through the first interval d15. 【0292】 The right side wall 43 is surrounded by air A flowing downward from the upper end 401Au in the outside O. Therefore, the interior I4 and interior I5 are surrounded by air A flowing downward from the upper end 401Au in the outside O. 【0293】 (4) In the feature equipment 400, at all approximate ends of the first member 401 except for the approximate end of the first member 401 that is furthest from the opening V, the filler material 403A and filler material 403B fill the first gap d15 so that the first gap d15 is not in communication with the outside O. 【0294】When an opening from which air is blown into a first interval is close to a point from which air flows out of the first interval to the outside, the air is immediately blown out of the opening. As a result, air does not flow widely in the first interval, and a wide insulating layer is not formed. 【0295】 Of the ends of the first member 401, all ends except the upper end 401u, which is furthest from the opening V, are not in communication with the outside O. Air A is blown out from the opening V and flows to the first gap d15 at the upper end 401u, which is furthest from the opening V. Air A flows widely at the first gap d15, forming a wide thermal insulation layer. Therefore, the equipment 400 can achieve energy savings in the interior I4 and interior I5 of the data center 40. 【0296】 <Fifth Embodiment> (1) Overall Configuration Hereinafter, we will omit explanations of the similarities between the first and fifth embodiments and will focus on the differences between the first and fifth embodiments. Figure 57 is a schematic diagram showing the overall configuration of the equipment system 5. The equipment system 5 mainly comprises a house 50, an air conditioner (not shown), and equipment 500. 【0297】 (1-1) Housing Housing 50 is a house or part of a house used for the residence of person H. The detailed configuration of housing 50 will be described later. 【0298】 The facility system 5 may, instead of a house 50, include any of the following: a greenhouse (such as greenhouse 10), a hothouse, a mushroom cultivation facility, a plant factory (such as plant factory 60), a land-based aquaculture farm, a livestock barn (such as livestock barn 20), a warehouse (such as warehouse 30), a data center (such as data center 40), a commercial building, an industrial building, an agricultural building, or a residential building. 【0299】 (1-2) Air conditioners Air conditioners perform air conditioning of the interior I6. Examples of air conditioning include cooling, heating, ventilation, air purification, dehumidification, and humidification. 【0300】 (1-3) Equipment Equipment 500 is equipment that forms an insulating layer with air A flowing from the interior I6 to the exterior O of the house 50. The detailed configuration of equipment 500 will be described later. 【0301】(2) Detailed configuration (2-1) House drawing 58 is a perspective view showing the detailed configuration of the house 50. The house 50 mainly consists of a front wall 51, a left side wall 52, a right side wall 53, a rear wall 54, and a ceiling 55. 【0302】 The front wall 51, the left wall 52, the right wall 53, and the rear wall 54 are vertical walls erected approximately perpendicular to the floor surface F. The front wall 51, the left wall 52, the right wall 53, the rear wall 54, and the ceiling 55 are components that are in contact with the outside O. 【0303】 An entrance / exit D is provided in the front wall 51. Entrance / exit D is an entrance from the outside O to the inside I6. Entrance / exit D is also an exit from the inside I6 to the outside O. Windows W are provided in the left wall 52 and the rear wall 54. 【0304】 An opening V is provided in the right wall 53. The opening V is an opening through which air flows from the interior I6 to the exterior O. A ventilation device (not shown) is provided in the opening V. The ventilation device is a device that, when driven, flows air A from the interior I6 to the exterior O. The right wall 53 does not have a window W or an entrance / exit D. 【0305】 The ceiling 55 faces the floor surface F and is connected to the front wall 51, the left side wall 52, the right side wall 53, and the rear wall 54. 【0306】 The right wall 53 is a first component. The first component is a component of the house 50 that is in contact with the outside O and is provided with an opening V. 【0307】 The front wall 51, the left side wall 52, the rear wall 54, and the ceiling 55 are second components. The second components are components of the house 50 that are in contact with the outside O and do not have openings V. 【0308】 The interior I6 is formed when the area of ​​the floor surface F is surrounded by the front wall 51, the left side wall 52, the right side wall 53, the rear wall 54, and the ceiling 55. 【0309】(2-2) Figure 59 is a perspective view showing the detailed configuration of the equipment 500. Figure 60 is a front view showing the detailed configuration of the equipment 500. Figure 61 is a rear view showing the detailed configuration of the equipment 500. Figure 62 is a left side view showing the detailed configuration of the equipment 500. Figure 63 is a right side view showing the detailed configuration of the equipment 500. Figure 64 is a top view showing the detailed configuration of the equipment 500. The equipment 500 mainly consists of a first member 501 and four support bases Su. 【0310】 (2-2-1) The first member 501 is a member provided with a first interval d16 between the right side wall 53 and the first member 501, from the right side wall 53. The length of the first interval d16 is 2 cm or more and 10 cm or less, but is not limited thereto. The first interval d16 is approximately equal in length over substantially the entire area between the first member 501 and the right side wall 53 where the first interval d16 is formed. 【0311】 The first member 501 has a plate-like shape. The first member 501 is provided so as to face the opening V and substantially the entire area of ​​the right side wall 53. The first member 501 has four ends: a front end 501f, a rear end 501b, an upper end 501u, and a lower end 501d. 【0312】 The first member 501 is not connected to other components of the equipment 500 at its front end 501f, rear end 501b, and upper end 501u. Therefore, the first gap d16 is in communication with the outside O at its front end 501f, rear end 501b, and upper end 501u. The first member 501 is in contact with the ground T at its lower end 501d. 【0313】 Furthermore, a mesh-like member to prevent animals from entering may be provided in the first interval d16 between the front end 501f, the rear end 501b, and the upper end 501u. 【0314】 (2-2-2) Support bases The support bases Su are provided at each corner of the first member 501 and support the first member 501. The support bases Su are fixed to the right side wall 53. 【0315】The equipment 500 does not necessarily have to be equipped with a support base Su. In this case, the first member 501 is fixed to the ground T. The equipment system 5 may also further include equipment similar in configuration to equipment 500, facing at least one of the left wall 52 and the rear wall 54. 【0316】 (3) The flow of air A from the interior I6 in the airflow equipment system 5 will be explained. The air conditioner supplies warmer or cooler air A to the interior I6 than the exterior O. The ventilation device is driven to circulate air A. Figure 65 is a schematic diagram of the equipment system 5 showing the flow of air A. 【0317】 As the ventilation device is activated, air A flows into the opening V inside I6 (not shown). Air A is drawn into the opening V by the ventilation device (not shown). Air A is blown out by the ventilation device into the first gap d16 between the opening V and the first member 501 (not shown). 【0318】 The air pressure at the first interval d16 between the upper end 501u, the front end 501f, and the rear end 501b is close to atmospheric pressure because it is in communication with the outside O. Therefore, the air A blown out from the opening V flows into the first interval d16 between the upper end 501u, the front end 501f, and the rear end 501b. The air A then flows from the first interval d16 between the upper end 501u, the front end 501f, and the rear end 501b to the outside O. 【0319】 Almost the entire area of ​​the right wall 53 is enveloped by the air A flowing through the first interval d16. Therefore, the interior I6 is enveloped by the air A flowing through the first interval d16. 【0320】 (4) The characteristic equipment 500 has a first interval d16 that communicates with the outside O at multiple approximate ends of the first member 501. 【0321】 The air pressure at the end connected to the outside O is close to atmospheric pressure. When there are multiple ends connected to the outside O, the air A blown out from the opening V forms multiple airflows directed toward the multiple ends with lower air pressure. Therefore, the equipment 500 can ventilate smoothly through multiple approximate ends while forming an insulating layer with the air A. 【0322】<Sixth Embodiment> (1) Overall Configuration Hereinafter, we will omit explanations of the similarities between the first embodiment and the sixth embodiment, and will focus on explaining the differences between the first embodiment and the sixth embodiment. Figure 66 is a schematic diagram showing the overall configuration of the equipment system 6. The equipment system 6 mainly comprises a plant factory 60, an air conditioner (not shown), and equipment 600. 【0323】 (1-1) Plant factory A plant factory 60 is a building in which plants P are cultivated. Inside the plant factory 60, racks R are provided I7. Plants P are cultivated on racks R. Plants P are either planted in soil (not shown) on racks R or immersed in nutrient solution (not shown) on racks R. The detailed configuration of the plant factory 60 will be described later. Behind the plant factory 60 is a structure 69. 【0324】 The equipment system 6 may also include, instead of the plant factory 60, any of the following: a greenhouse (such as greenhouse 10), a hothouse, a mushroom cultivation facility, a land-based aquaculture farm, a livestock barn (such as livestock barn 20), a warehouse (such as warehouse 30), a data center (such as data center 40), a commercial building, an industrial building, an agricultural building, or a residential building (such as house 50). 【0325】 (1-2) Air conditioners Air conditioners perform air conditioning of the interior I7. Examples of air conditioning include cooling, heating, ventilation, air purification, dehumidification, and humidification. 【0326】 (1-3) Equipment Equipment 600 is equipment that forms an insulating layer with air A flowing from the inside I7 to the outside O of the plant factory 60. The detailed configuration of equipment 600 will be described later. 【0327】 (2) Detailed configuration (2-1) Plant factory diagram 67 is a perspective view showing the detailed configuration of the plant factory 60. The plant factory 60 mainly consists of a front wall 61, a left side wall 62, a right side wall 63, a rear wall 64, and a ceiling 65. 【0328】 The front wall 61, the left wall 62, the right wall 63, and the rear wall 64 are vertical walls erected approximately perpendicular to the floor surface F. The front wall 61, the left wall 62, the right wall 63, the rear wall 64, and the ceiling 65 are components that are in contact with the outside O. 【0329】 An opening V is provided in front of the center in the Z direction of the right wall 63. In other words, the opening V is provided in front of the center in the Z direction of the plant factory 60. The opening V is an opening through which air A flows from the interior I7 to the exterior O. A ventilation device (not shown) is provided in the opening V. The ventilation device is a device that drives air A from the interior I7 to the exterior O. The right wall 63 does not have a window or an entrance / exit D. 【0330】 The ceiling 65 faces the floor surface F and is connected to the front wall 61, the left wall 62, the right wall 63, and the rear wall 64. 【0331】 The right side wall 63 is a first component. The first component is a component of the plant factory 60 that is in contact with the outside O and is provided with an opening V. 【0332】 The front wall 61, the left side wall 62, the rear wall 64, and the ceiling 65 are second components. The second components are components of the plant factory 60 that are in contact with the outside O and do not have an opening V. 【0333】 The interior I7 is formed when the area of ​​the floor surface F is surrounded by the front wall 61, the left side wall 62, the right side wall 63, the rear wall 64, and the ceiling 65. 【0334】 (2-2) Figure 68 is a perspective view showing the detailed configuration of equipment 600. Figure 69 is a front view showing the detailed configuration of equipment 600. Figure 70 is a rear view showing the detailed configuration of equipment 600. Figure 71 is a left side view showing the detailed configuration of equipment 600. Figure 72 is a right side view showing the detailed configuration of equipment 600. Figure 73 is a top view showing the detailed configuration of equipment 600. Equipment 600 mainly consists of a first member 601, a filler material 603A, and a filler material 603B. 【0335】 (2-2-1) The first member The first member 601 is a member provided with a first interval d17 between the right side wall 63 and the first member 601, from the right side wall 63. The length of the first interval d17 is 2 cm or more and 10 cm or less, but is not limited thereto. The first interval d17 is approximately equal in length over substantially the entire area between the first member 601 and the right side wall 63 where the first interval d17 is formed. 【0336】 The first member 601 has a plate-like shape. The first member 601 is provided so as to face the opening V and substantially the entire area of ​​the right side wall 63. The first member 601 has four ends: a front end 601f, an upper end 601u, a lower end 601d, and a rear end 601b. 【0337】 The first member 601 is connected to the filler material 603A at its front end 601f. The first member 601 is connected to the filler material 603B at its upper end 601u. The first member 601 is in contact with the ground T at its lower end 601d. The first member 601 is not connected to any other components of the equipment 600 at its rear end 601b. Therefore, the first gap d17 is in communication with the outside O at its rear end 601b. 【0338】 Of the four ends of the first member 601, the end closest to the structure 69 is the rear end 601b. A mesh-like member to prevent animal intrusion may be provided at the first interval d17 at the rear end 601b. 【0339】 (2-2-2) Filler material Filler material 603A fills the first gap d17 at the front end portion 601f so that the first gap d17 is not in communication with the outside O. Filler material 603B fills the first gap d17 at the upper end portion 601u so that the first gap d17 is not in communication with the outside O. 【0340】 The shape of the filler material 603A and filler material 603B is that of an elongated plate-like member. The filler material 603A and filler material 603B are pre-processed so that they can be fitted into the first gap d17. Alternatively, the filler material 603A and filler material 603B may be formed by later filling the first gap d17 with expanded polystyrene or expanded urethane, etc. 【0341】 The structure 69 faces the rear end 601b. At the rear end 601b, the first interval d17 communicates with the outside O. Therefore, the structure 69 faces the first interval d17. 【0342】Of the four ends of the first member 601, the end closest to the structure 69 is the rear end 601b. Filler material 603A fills the first gap d17 at the front end 601f. Filler material 603B fills the first gap d17 at the upper end 601u. The ground T prevents the first gap d17 at the lower end 601d from communicating with the outside O. Therefore, filler materials 603A and 603B prevent the first gap d17 at all ends of the first member 601 except the rear end 601b, which is closest to the structure 69, from communicating with the outside O. 【0343】 Furthermore, the equipment system 6 may also include equipment in a configuration similar to that of equipment 600, positioned to face at least one of the left wall 62 and the rear wall 64. 【0344】 (3) The flow of air A from the interior I7 in the airflow equipment system 6 will be explained. The air conditioner supplies warmer or cooler air A to the interior I7 than the outside O. The ventilation device is driven to circulate air A. Figure 74 is a schematic diagram of the equipment system 6 showing the flow of air A. 【0345】 As the ventilation device is activated, air A flows into the opening V inside I7 (not shown). Air A is drawn into the opening V by the ventilation device (not shown). Air A is blown out by the ventilation device into the first gap d17 between the opening V and the first member 601 (not shown). 【0346】 The air pressure at the first interval d17 at the rear end 601b is close to atmospheric pressure because it is in communication with the outside O. Therefore, the air A blown out from the opening V flows into the first interval d17 at the rear end 601b. The air A flows from the first interval d17 at the rear end 601b to the outside O. The air A that flows to the outside O collides with the structure 69. The air A that collides with the structure 69 flows between the plant factory 60 and the structure 69. 【0347】 Almost the entire area of ​​the right wall 63 is enveloped by the air A flowing through the first interval d17. Therefore, the interior I7 is enveloped by the air A flowing through the first interval d17. 【0348】The plant factory 60 is enveloped by the air A flowing between the plant factory 60 and the structure 69. Therefore, the interior I7 is enveloped by the air A flowing between the plant factory 60 and the structure 69. 【0349】 (4) The characteristic equipment 600 is such that, at all approximate ends of the first member 601 except for the approximate end of the first member 601 that is in the shortest distance from another structure 69 facing the first interval d17, the filler material 603A and filler material 603B fill the first interval d17 so that the first interval d17 is not in communication with the outside O. 【0350】 Therefore, the air A flowing from the first gap d17 to the outside O flows between the plant factory 60 and the structure 69. The air A forms an insulating layer between the plant factory 60 and the structure 69. Thus, the equipment 600 can achieve energy savings in the interior I7 of the plant factory 60. 【0351】 <Seventh Embodiment> (1) Configuration A facility system of any embodiment from the first to sixth embodiments and their respective modifications, wherein at least one of the following is provided: a solar panel is provided on at least a part of the first member; a solar panel is provided in place of at least a part of the first member; a solar panel is provided on at least a part of the second member; or a solar panel is provided in place of at least a part of the second member. 【0352】 Figure 75 is a schematic diagram showing the overall configuration of the equipment system 7. Figure 75 shows an example in which the position of the opening V is changed to the ceiling from the equipment system of the second embodiment, and solar panels SP are provided on at least a part of the first member. The equipment system 7 is not limited to the example shown in Figure 75. 【0353】 A solar panel SP is a panel that can generate electricity using sunlight as an energy source. The solar panel SP is installed so that its surface (the side that receives sunlight) faces the outside O. A solar panel SP may also be a collection of smaller solar panels. 【0354】(2) Characteristics: Solar panels use sunlight as an energy source and convert a portion of it into electrical energy. However, thermal energy that is not converted into electrical energy is generated from the solar panel. To improve the power generation efficiency of the solar panel, it is necessary to cool the solar panel. 【0355】 In the equipment system 7, the air flowing through at least one of the first and second intervals flows to the back of the solar panel SP (the back of the surface that receives sunlight). If the temperature of this air is lower than the temperature of the back of the solar panel SP, the air will cool the solar panel SP due to thermal convection, etc. 【0356】 In particular, during periods when thermal energy tends to accumulate in the solar panels SP, the temperature difference between the air flowing from inside the equipment and the temperature on the back of the solar panels SP can become larger. Therefore, the efficiency of cooling the solar panels SP by this air increases. 【0357】 Furthermore, the higher the temperature of the solar panels SP becomes compared to the internal temperature of the equipment, the greater the force that pulls air from inside the equipment from at least one of the first and second intervals. This is because as the temperature increases, the density decreases and the pressure decreases. Therefore, the equipment system 7 improves the ventilation and insulation capacity of the equipment while also increasing the cooling efficiency for the solar panels SP. 【0358】 While embodiments of this disclosure have been described above, it should be understood that various modifications to the form and details are possible without departing from the spirit and scope of this disclosure as described in the claims. 【0359】 The equipment relating to this disclosure can be used industrially according to the embodiments of this disclosure. 【0360】 100 Equipment A Air O External V Opening
