[Technical field]

[0001] The present invention relates to buildings. [Background technology]

[0002] 2. Description of the Related Art In buildings such as buildings and houses having multiple floors, it is common for each floor to be cooled by air conditioning equipment provided on each floor (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-89080 [Patent Document 2] Special Publication No. 2014-519012 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the cooling system for buildings as described above does not provide sufficient energy conservation for the entire building. In particular, buildings with multiple floors and large spaces consume a lot of energy for cooling in the summer, so sufficient energy conservation is required.

[0005] The present invention has been made in consideration of the above points, and one of its objects is to provide a building that is capable of cooling a large space while saving energy. [Means for solving the problem]

[0006] A building according to one embodiment of the present invention has an atrium that connects multiple floors vertically and cooling vents that spray cool air upward from the floor of each floor, and the multiple floors with the atrium have a first floor equipped with a cooling vent and a second floor located below the first floor and not equipped with a cooling vent.

[0007] According to this aspect, by providing a cooling port on the first floor with an atrium that sprays cold air upward from the floor, it is possible to mainly cool the space where people move (the space from the floor to the height of the people) without cooling the entire space of the first floor, thereby saving energy. Furthermore, since the building has a first floor with an atrium and a cooling port, and a second floor located below the first floor and not equipped with a cooling port, the cold air from the first floor can be sent through the atrium to the second floor below, and the second floor can be cooled with that cold air. This provides a building that can cool a large space while saving energy.

[0008] In the above aspect, the first floor may be made up of multiple floors, and may have an upper floor and a lower floor that is lower than the upper floor, and the lower floor may have a floor portion that protrudes toward the atrium side more than the floor portion of the upper floor.

[0009] In the above aspect, the first floor may be made up of multiple floors, and may have an upper floor and a lower floor that is lower than the upper floor, and the upper floor may have a floor portion that protrudes toward the atrium side more than the floor portion of the lower floor.

[0010] In the above aspect, the lower floor may be located directly below the upper floor.

[0011] In the above aspect, the atrium may have an atrium section on each floor, and at least some of the atrium sections on floors that are adjacent to each other vertically may be configured so that their horizontal center positions are offset from each other.

[0012] In the above embodiment, the second floor may be the bottom floor.

[0013] In the above aspect, the first floor may have a partition wall erected vertically at the floor edge facing the atrium.

[0014] In the above embodiment, the partition wall may have a height of 110 cm or more and 180 cm or less.

[0015] In the above embodiment, the multiple floors include an entrance floor having an entrance hall, and the second floor directly above the entrance floor and the third floor directly above the second floor are first floors, and the second floor has a floor section that protrudes toward the atrium side more than the floor section of the third floor, and the protruding length of the floor section of the second floor relative to the floor section of the third floor may be smaller for the floor section on the entrance hall side than for the floor section on the opposite side across the atrium from the entrance hall.

[0016] In the above embodiment, the multiple floors include an entrance floor having an entrance hall, and directly above the entrance floor there are multiple first floors, and the multiple first floors may be formed in a stepped manner on the opposite side of the atrium from the entrance hall so that the floors of the floors closer to the entrance floor protrude toward the atrium.

[0017] In the above embodiment, the entrance level may be the second level. Effect of the Invention

[0018] According to the present invention, it is possible to provide a building capable of cooling a large space in an energy-efficient manner. [Brief description of the drawings]

[0019] [Figure 1] FIG. 1 is a schematic diagram showing a cross section of a building for explaining the structure of the building in accordance with the present embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] An example of a preferred embodiment of the present invention will now be described with reference to the drawings. Fig. 1 is a schematic diagram showing a vertical section of a building 1 according to this embodiment.

[0021] The building 1 has multiple floors, for example, four floors 1F, 2F, 3F, and 4F. The building 1 has an atrium 10 that vertically connects the four floors 1F to 4F. The atrium 10 is provided, for example, near the center of the building 1, not at the end in the horizontal direction.

[0022] The first floor (1F) is an entrance floor, and has an entrance hall 31 with a door 30 serving as the building entrance. The entrance hall 31 is connected to the atrium 10 without any partition.

[0023] The second floor 2F, the third floor 3F, and the fourth floor 4F are provided with cooling vents 40 that blow cool air upward from the floors of the floors. In this embodiment, the second floor 2F, the third floor 3F, and the fourth floor 4F correspond to the first floor provided with a cooling vent in the present invention.

[0024] A large number of cooling vents 40 are provided on the floor of a space that is open to at least the atrium 10 on each of the 2nd to 4th floors. The cooling vents 40 may also be provided on the floor of a room that is separated from the atrium 10 on each of the 2nd to 4th floors. The cooling vents 40 are made of, for example, a porous floorboard and a porous carpet tile. The cooling devices 50 are provided under the floors of each of the 2nd to 4th floors. The cooling vents 40 are configured to blow cold air sent from the cooling devices 50 on each of the 2nd to 4th floors through the floor and above the floor. The cooling devices 50 are not particularly limited, but may be, for example, air conditioners. The number and arrangement of the cooling devices 50 are not particularly limited.

[0025] The first floor 1F is not provided with the above-mentioned cooling vent 40. Note that, for example, in the perimeter area near the windows of each of the floors 1F to 4F, a device that blows cool air from the ceiling or the like other than the floor, different from the cooling vent 40, may be provided. The first floor 1F corresponds to the second floor in the present invention that does not have a cooling vent.

[0026] Each of the second to fourth floors has partition walls 60, 61, 62 erected vertically on the edge of the floor facing the atrium 10. The partition walls 60 to 62 have a height of, for example, 110 cm to 180 cm from the floor surface.

[0027] The second floor 2F has a front floor section 70 located on the entrance hall 31 side of the atrium 10, and a back floor section 71 located on the opposite side of the entrance hall 31 with respect to the atrium 10, for example, along the first horizontal direction X. The first horizontal direction X is a direction along the traffic line from the entrance hall 31 toward the atrium 10. The second floor 2F also has floor sections 72 on both sides of the atrium 10 in the second horizontal direction Y. The second horizontal direction Y is a direction perpendicular to the first horizontal direction X. The cooling vents 40 are provided in the front floor section 70, the back floor section 71, and the floor section 72, respectively. The partition wall 60 is provided at the tip of the front floor section 70, the back floor section 71, and the floor section 72 on the atrium 10 side.

[0028] The third floor 3F has a front floor section 80 located on the entrance hall 31 side of the atrium 10, for example along the first horizontal direction X, and a back floor section 81 located on the opposite side of the entrance hall 31 from the atrium 10. The third floor 3F also has floor sections 82 on both sides of the atrium 10 in the second horizontal direction Y. Cooling vents 40 are provided in the front floor section 80, the back floor section 81, and the floor section 82, respectively. Partition walls 61 are provided at the ends of the front floor section 80, the back floor section 81, and the floor section 82 on the atrium 10 side.

[0029] The fourth floor 4F has a front floor section 90 located on the entrance hall 31 side of the atrium 10, and a back floor section 91 located on the opposite side of the entrance hall 31 with respect to the atrium 10, for example, along the first horizontal direction X. The fourth floor 4F also has floor sections 92 on both sides of the atrium 10 in the second horizontal direction Y. The cooling vents 40 are provided in the front floor section 90, the back floor section 91, and the floor section 92, respectively. The partition walls 62 are provided at the tips of the front floor section 90, the back floor section 91, and the floor section 92 on the atrium 10 side. The fourth floor 4F has a ceiling section 93 through which external light from the building 1 is taken in. The ceiling section 93 is provided in a position corresponding to the atrium 10 (above the atrium 10). The ceiling section 93 through which external light is taken in may be a part or all of the ceiling of the atrium 10.

[0030] A rear floor portion 81 on the third floor 3F has a protruding portion 81a that protrudes further toward the void 10 than a rear floor portion 91 on the fourth floor 4F directly above. A length L1 of the protruding portion 81a of the rear floor portion 81 is 5m or more.

[0031] The rear floor portion 71 on the second floor 2F has a protruding portion 71a that protrudes further toward the atrium 10 than the rear floor portion 81 on the third floor 3F directly above. The length L2 of the protruding portion 71a of the rear floor portion 71 is 5m or more. For example, the length L1 of the protruding portion 81a and the length L2 of the protruding portion 71a may be the same, or one of them may be longer.

[0032] The front floor section 90 on the fourth floor 4F has a protruding section 90a that protrudes further toward the atrium 10 than the front floor section 80 on the third floor 3F directly below. The length L3 of the protruding section 90a of the front floor section 90 is 5m or more. The front floor section 90 on the fourth floor 4F protrudes further toward the atrium 10 than the front floor section 70 on the second floor 2F.

[0033] The front floor portion 70 on the second floor 2F has a protruding portion 70a that protrudes further toward the void 10 than the front floor portion 80 on the third floor 3F directly above. The length L4 of the protruding portion 70a of the front floor portion 70 is 1 m or more.

[0034] A length L4 of the protruding portion 70a of the front floor portion 70 relative to the front floor portion 80 is smaller than a length L2 of the protruding portion 71a of the rear floor portion 71 relative to the rear floor portion 81. In other words, the rear floor portion 71 on the second floor 2F protrudes further relative to the floor portion on the third floor 3F than the front floor portion 70.

[0035] The rear floor section 91 of the fourth floor 4F, the rear floor section 81 of the third floor 3F, and the rear floor section 71 of the second floor 2F are formed in a stepped shape so that the floor sections closer to the first floor 1F protrude toward the atrium 10.

[0036] The atrium 10 has atrium sections 10a, 10b, 10c, and 10d on each of the floors 1F to 4F. The atrium sections 10b to 10d on the second floor 2F to the fourth floor 4F have centers that are offset from each other at least in the first horizontal direction X. The center of the atrium section 10b on the second floor 2F is the center between the front floor section 70 and the rear floor section 71 in the first horizontal direction X, the center of the atrium section 10c on the third floor 3F is the center between the front floor section 80 and the rear floor section 81 in the first horizontal direction X, and the center of the atrium section 10d on the fourth floor 4F is the center between the front floor section 90 and the rear floor section 91 in the first horizontal direction X.

[0037] The opening area forming the atrium 10d surrounded by floors 90, 91, 92 on the fourth floor 4F in plan view, the opening area forming the atrium 10c surrounded by floors 80, 81, 82 on the third floor 3F in plan view, and the opening area forming the atrium 10b surrounded by floors 70, 71, 72 on the second floor 2F in plan view may have the same shape and size, or may have different shapes and sizes. The opening areas forming each of the atriums 10a to 10d in plan view may have a polygonal shape such as a square, or may have a circular or elliptical shape.

[0038] Stairs 100, 101, 102 are provided in the exposed portions of the floors of the 1st to 4th floors in the atrium 10 for moving between adjacent upper and lower floors. The first staircase 100 connects the floor of the atrium 10a on the 1st floor 1F to the protruding portion 71a of the rear floor 71 on the 2nd floor 2F. The second staircase 101 connects the protruding portion 71a of the rear floor 71 on the 2nd floor 2F to the floor 82 on the 3rd floor 3F. The third staircase 102 connects the protruding portion 81a of the rear floor 81 on the 3rd floor 3F to the floor 92 on the 4th floor 4F.

[0039] Next, a cooling method for the building 1 configured as described above will be described. For example, on the second floor 2F to the fourth floor 4F, cold air A supplied from the cooling device 50 is ejected upward from the cooling vent 40 in the floor. The cold air A is ejected at a flow rate (pressure) sufficient to reach a height of about a person's height. On the second floor 2F to the fourth floor 4F, the cold air A on each of the floors 2F to 4F is temporarily blocked by the partition walls 60 to 62 and is stored in the space inside the partition walls 60 to 62. Note that on the first floor 1F, there is no cooling vent 40, so cold air does not eject from the floor.

[0040] Thereafter, for example, the cold air A on the fourth floor 4F passes over the partition wall 62, flows into the atrium 10, and descends through the atrium 10. The cold air A on the back floor 91 on the fourth floor 4F falls onto the protruding portion 81a of the back floor 81 on the third floor directly below, cooling the protruding portion 81a. The cold air A on the front floor 90 on the fourth floor 4F descends through the atrium 10 to the first floor 1F. This cold air A falls passing near the center in the first horizontal direction X of the atrium 10c on the third floor 3F and near the center in the first horizontal direction X of the atrium 10b on the second floor 2F.

[0041] The cold air A on the third floor 3F passes over the partition wall 61, flows into the atrium 10, and descends through the atrium 10. The cold air A on the rear floor 81 on the third floor 3F, together with the cold air A that falls from the rear floor 91 on the fourth floor 4F, falls onto the protruding part 71a of the rear floor 71 on the second floor directly below, cooling the protruding part 71a. A part of the cold air A on the front floor 80 on the third floor 3F falls onto the protruding part 70a of the front floor 70 on the second floor 2F directly below, cooling the protruding part 70a. A part of the cold air A on the front floor 80 on the third floor 3F descends through the atrium 10 to the first floor 1F. This cold air A passes through the space below the protruding part 90a of the front floor 90 on the fourth floor 4F directly above.

[0042] The cold air A on the second floor 2F passes over the partition wall 60, flows into the atrium 10, and falls through the atrium 10. The cold air A on the back floor 71 of the second floor 2F falls to the first floor 1F directly below, together with the cold air A that has fallen from the back floor 81 of the third floor 3F, and cools the first floor 1F. The cold air A on the front floor 70 of the second floor 2F falls to the first floor 1F directly below, together with the cold air A that has fallen from the front floor 80 of the third floor 3F, and cools the first floor 1F. The cold air A on the first floor 1F is supplied to the entrance hall 31, etc.

[0043] According to this embodiment, by providing cooling vents 40 on the second floor 2F to the fourth floor 4F, through which cold air A is sprayed upward from the floor, it is possible to mainly cool the space where people move (the space from the floor surface to the height of the person) without cooling the entire space on the second floor 2F to the fourth floor 4F, thereby saving energy. Furthermore, since the building 1 has an atrium 10, the second floor 2F to the fourth floor 4F equipped with cooling vents 40, and the first floor 1F not equipped with cooling vents 40, the cold air A on the second floor 2F to the fourth floor 4F can be sent through the atrium 10 to the first floor 1F below, and the cold air A can be used to cool the first floor 1F below. This allows the large space of the building 1 to be cooled in an energy-efficient manner.

[0044] The second floor 2F to the fourth floor 4F have cooling openings 40, and the lower second floor 2F and third floor 3F have protruding parts 81a, 71a of the rear floor parts 81, 71 that protrude further toward the atrium 10 than the rear floor part 91 of the upper fourth floor 4F. This allows the cold air A from the cooling opening 40 on the fourth floor 4F to cool the protruding parts 81a, 71a of the lower floors, while also cooling the first floor 1F which does not have a cooling opening 40. In particular, the protruding part 81a of the third floor 3F directly below is cooled effectively.

[0045] The second floor 2F to the fourth floor 4F have cooling ports 40, and the fourth floor 4F has a protruding portion 90a of the front floor portion 90 that protrudes toward the atrium 10 side more than the front floor portions 80, 70 of the third floor 3F and the second floor 2F below. In this case, the edges of the front floor portions 80, 70 of the third floor 3F and the second floor 2F, which are difficult for the cold air A from the cooling port 40 of the fourth floor 4F to reach, can be appropriately cooled by the cold air A from the cooling port 40 of the third floor 3F and the second floor 2F. In particular, the edges of the front floor portion 80 of the third floor 3F directly below are effectively cooled. In addition, since the cold air A of the fourth floor 4F easily descends directly to the first floor 1F through the atrium 10, the first floor 1F, which does not have a cooling port 40, can be effectively cooled.

[0046] The atrium 10 has atrium sections 10a to 10d on the respective floors 1F to 4F, and at least the atrium sections 10b to 10d on the second floor 2F to the fourth floor 4F that are vertically adjacent to each other are configured so that the center positions in the first horizontal direction X are offset from each other. This allows, for example, the centers of the atrium sections 10b, 10c on the lower floors 2F and 3F to be cooled by the cold air A descending from the atrium section 10d on the upper fourth floor 4F, and the entire building can be cooled uniformly.

[0047] Since the floor not provided with the cooling vent 40 is the lowest floor, the first floor 1F, the cool air A can be appropriately supplied to the first floor 1F which does not have the cooling vent 40. This allows the entire building to be appropriately cooled.

[0048] The second floor 2F to the fourth floor 4F, which have cooling vents 40, have partition walls 60 to 62 erected vertically at the floor edges facing the atrium 10, so that it is possible to prevent the cold air A from the cooling vents 40 on each floor from flowing into the atrium 10 before the floor is sufficiently cooled. Also, the cold air A can be sent to the atrium 10 from a high position by the height of the partition walls 60 to 62. As a result, the building 1 can be cooled efficiently.

[0049] Since the partition walls 60 to 62 have a height of 110 cm to 180 cm, the cool air is mainly collected in the area where people are moving, and the area can be cooled intensively. As a result, energy saving is promoted.

[0050] Length L4 of protruding portion 70a of front floor portion 70 relative to front floor portion 80 on the entrance hall 31 side is shorter than length L2 of protruding portion 71a of rear floor portion 71 relative to rear floor portion 81 on the opposite side of entrance hall 31. For this reason, the entrance hall 31 side has a structure in which cool air A from the third floor 3F, in addition to cool air A from the second floor 2F, easily falls into the entrance hall 31. As a result, the entrance hall 31, where there is a lot of movement of people, can be effectively cooled.

[0051] Additionally, the rear floor section 91 of the fourth floor 4F, the rear floor section 81 of the third floor 3F, and the rear floor section 71 of the second floor 2F are formed in a stepped shape so that the floor sections on the floors closer to the first floor 1F, which is the entrance floor, protrude toward the atrium 10. This allows cool air A to flow smoothly toward the entrance hall 31, making it possible to effectively cool the entrance hall 31 where a lot of people move around.

[0052] Generally, the amount of energy required for cooling increases on the entrance floor, especially in summer. In this embodiment, the first floor 1F, which is the entrance floor, does not have a cooling vent 40, and the first floor 1F can be sufficiently cooled, which further promotes energy conservation.

[0053] Although the preferred embodiment of the present invention has been described above with reference to the accompanying drawings, the present invention is not limited to such an example. It is clear that a person skilled in the art can come up with various modified or altered examples within the scope of the ideas described in the claims, and it is understood that such examples also naturally belong to the technical scope of the present invention.

[0054] For example, the structure of the building 1 is not limited to that of the above embodiment. The building 1 may have a basement floor. The building 1 does not have to have four floors, but may have two or more floors. The building 1 may have three or more floors, or five or more floors. The atrium 10 does not have to connect all floors of the building 1, but may connect some floors of the building 1. The floors having the cooling vent 40 are not limited to the second floor 2F to the fourth floor 4F. The floors having the cooling vent 40 may be one or more floors. The floors not having the cooling vent 40 are not limited to the first floor 1F. The floors not having the cooling vent 40 may be one or more floors. The structure in which the floors of the second floor 2F to the fourth floor 4F protrude in the first horizontal direction X is also not limited to that of the above embodiment. The direction in which the floors of the floors of the floors 2F to 4F protrude relative to the floors of the other floors may be the second horizontal direction Y, not limited to the first horizontal direction X. [Industrial Applicability]

[0055] The present invention is useful in providing a building capable of cooling a large space with energy saving. [Explanation of symbols]
