Description

Technical Field

[0001] The present invention relates to the field of architecture, and in particular to an extremely low specific surface area building provided with a strip-shaped viewing platform. Background Art

[0002] Under the building design specifications, the structural design of a building must meet the rigid constraints of natural ventilation and lighting indicators.

[0003] In order to make the building meet the restrictive requirements of natural lighting and ventilation, designers must adopt technical measures such as multiple separate buildings, thinning the thickness of single buildings, and setting up recessed lighting and ventilation structures to achieve north-south transparency in the building, and to make the kitchen and bathroom windows face outward, to ensure sufficient natural lighting and ventilation.

[0004] However, the adoption of technical measures such as multiple separate buildings, thinning the thickness of single buildings, and installing special recessed lighting and ventilation structures will inevitably lead to large facade areas of each building and small effective building areas, which is ultimately reflected in the indicator of specific surface area, that is, the large specific surface area of the building.

[0005] The volume ratio of a building group is the ratio of the total building area on the ground to the total land area of the building group, which reflects the space utilization coefficient and the degree of crowding. The specific surface area of a building is the ratio of the total surface area of the building to the total building area, which is a core indicator reflecting the energy characteristics and structural characteristics of the building. A large specific surface area of a building means a large surface area and a unit building area (1m2). 2 ) is one of the fundamental reasons for the large average surface area, high building energy consumption, large consumption of exterior wall materials, complex construction technology, low overall volume ratio of the building complex and high housing prices.

[0006] High housing prices and high building energy consumption are two major problems that have been criticized in the real estate industry.

[0007] Land prices are certainly the driving force behind high housing prices, but the floor area ratio is a hedging factor for housing prices. A low floor area ratio will further increase housing prices, while a high floor area ratio will lower housing prices.

[0008] The high energy consumption of buildings is certainly related to the performance of wall insulation materials and building energy equipment such as air conditioners, but the floor area ratio and building specific surface area are also hedging factors. If the floor area ratio is high and the building specific surface area is small, the average external wall surface area per unit building area of the building is small, the energy exchange with the environment is weak, and the building energy consumption is low; conversely, if the floor area ratio is low and the building specific surface area is large, the average external wall surface area per unit building area of the building is large, the energy exchange with the environment is strong, and the building energy consumption is high.

[0009] At present, the building complex volume ratio index and building specific surface area index are constrained by existing planning specifications and architectural design specifications, which restricts the innovative development of buildings, especially large and extra-large buildings.

[0010] Promoting major innovations in building design technology and supporting technologies, breaking through the constraints of existing planning and building design codes, significantly increasing the plot ratio of building clusters and significantly reducing the specific surface area of buildings, while paying attention to and meeting the reasonable demands of the people inside the buildings to go outdoors, approach nature, and get close to nature, is the only choice to solve the two major problems of high housing prices and high energy consumption that have been much criticized in the real estate industry.

[0024] The specific surface area of the building is the ratio of the outer surface area of the building to the above-ground building area of the building. Preferably, the specific surface area of the building is preferably on the order of 10 -1 m 2 / m 2 order of magnitude or 10 -1 m 2 / m 2 or less order of magnitude.

[0025] Compared with the prior art, the present invention has the following technical effects:

[0026] 1. Meet the experience of the interaction between residents and the environment

[0027] In the present invention, a viewing platform is arranged at the edge of each floor of a building with an extremely low specific surface area, extremely low energy consumption, extremely high floor area ratio, and super-large scale, which meets the experience requirements of flat-floor residents to get out of their cramped living spaces, get close to nature, and interact with the environment. It also provides a landscape fitness track for flat-floor residents;

[0028] The viewing platform arranged at the edge of each floor of the present invention, as a shared space for all residents of the entire floor, also breaks the situation where residents in traditional residential buildings live in isolation from each other, which is conducive to enhancing the communication and cooperation between residents and cultivating and building harmonious neighborhood relations.

[0029] 2. Greatly save land, building materials and energy

[0030] The present invention adopts an overall cubic structure for the building, sets a plurality of super-large floors inside the overall cubic structure, and arranges townhouses or other functional unit spaces on each of the super-large floors, which can greatly increase the building floor area ratio from about 5.0 in traditional residential communities to more than 15.0, so as to realize intensive land use for buildings, greatly save land, and provide a good living space for ordinary people under high land price conditions.

[0031] The present invention adopts an overall regular cubic or nearly regular cubic structure for the building, sets a plurality of super-large floors inside the regular cubic or nearly regular cubic overall structure, and arranges townhouses on each of the super-large floors, cancels the protrusions and recesses on the outer facades of multiple single traditional residential buildings under the condition of equal building area, thus greatly saving exterior wall building materials, reducing the construction process difficulty and construction time, and greatly reducing the construction cost.

[0032] The present invention adopts the overall structure of a building in the shape of a regular cube or close to a regular cube. Multiple super-large flat floors are arranged within the overall structure of the regular cube or close to the regular cube. Townhouses are set on each super-large flat floor, so that the specific surface area index of the whole building is reduced to an extremely low level, presenting the architectural characteristics of ultra-large volume, ultra-high plot ratio, and extremely low specific surface area. The external wall area for the building to exchange energy with the environment per unit floor area of the residence, that is, the area of the building receiving environmental heat radiation in summer and emitting heat radiation to the environment in winter, is reduced to the lowest level, constructing a truly green and low-carbon building, greatly saving the building energy consumption which has become one of the three major main forces of the total social energy consumption and accounts for as high as 20%. In high-latitude regions, more than 3 / 4 of the heating and ventilation energy consumption of the residence can be saved, which is of great significance for reducing the total social carbon emissions.

[0033] 3. The secondary scenery and lighting conditions index inside the building is superior to the natural environment

[0034] In terms of specific single living conditions of human beings, the artificial secondary environment is superior to the original ecological environment, and this value judgment has been verified many times: multi-story and high-rise concrete residences are superior to caves, tap water is superior to the original ecological river water and groundwater, and flush toilets are superior to latrines; especially after the emergence of energy technologies such as artificial fire and air conditioners, cooked food at high temperature is superior to eating raw, semiconductor lighting is superior to sunlight radiation, the air-conditioning wind after cooling and dehumidifying in summer is superior to the environmental hot wind, and floor heating in winter is superior to open fires in the wild.

[0035] A space, as long as it can keep out wind and rain, can provide clean fresh air, suitable lighting, clean drinking water and sanitary hot water, stable electricity and network signals, and can smoothly discharge dirty air, excrement and garbage, it is a livable residence.

[0036] For a building with a strip-shaped viewing platform and an extremely low specific surface area according to the present invention, the effects of indoor fresh air replacement and the treatment, discharge and diffusion of dirty air and kitchen fumes all reach the extreme. The indicators such as temperature and humidity, oxygen content, cleanliness, noise, light intensity and light softness of the secondary artificial scenery and lighting environment inside the building are all superior to the original natural environment; and there are no more mosquito troubles in the residence; new technologies and new products for residences such as real-time external scene images introduced into the building, air-flow closed-loop circulation dehumidifying drying heat pumps, gas-free electric kitchens, and semiconductor cold light source lighting can also be introduced to create secondary climate conditions and living conditions that originate from the natural environment and are higher than the natural environment.

[0037] 4. High strength of the building

[0038] The present invention adopts an overall cubic structure for a building, with multiple extra-large flat floors arranged within the overall cubic structure. Townhouses are set on each of the extra-large flat floors, and a grid-like composite building system is constructed in an integrated manner of columns (or shear walls) - main beams - secondary beams - floor slabs, significantly enhancing the overall strength and seismic performance of the building structure, and effectively eliminating the problem of external wall leakage that widely exists in traditional buildings of the same floor area.

[0055] The following will combine Figures 1 to 14 A building with a ribbon - shaped viewing platform and an extremely low specific surface area provided by the present invention will be described in detail. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation manners and specific operation processes are given. However, the protection scope of the present invention is not limited to the following embodiments, and those skilled in the art can modify and polish it without changing the spirit and content of the present invention.

[0056] Embodiment 1

[0057] A building with a ribbon - shaped viewing platform and an extremely low specific surface area provided by the present invention has a foundation of an extremely low specific surface area building.

[0058] A building with a ribbon - shaped viewing platform and an extremely low specific surface area of the present invention adopts an air - isolation structure with multiple flat layers in the vertical direction and multiple aisles in the horizontal direction, which is derived from two architectural physics concepts of "building specific surface area" and "double - low and double - super building" refined by the present invention.

[0059] The present invention defines the "specific surface area of a building" as "the ratio of the external surface area of a building to the above - ground building area of the building", and its essence is the external surface area evenly distributed per unit building area, with the unit of m 2 / m 2, is a dimensionless physical quantity and can be a core indicator reflecting the energy characteristics and structural characteristics of buildings. If the specific surface area of a building is large, the external surface area evenly distributed per unit building area is large, resulting in high building energy consumption, more consumption of external wall materials, complex construction technology, and low overall plot ratio of the building complex. Conversely, if the specific surface area of a building is small, the external surface area evenly distributed per unit building area is small, leading to low building energy consumption, less consumption of external wall materials, relatively simple construction technology, and high building plot ratio.

[0060] If the specific surface area, which is the core indicator of the energy characteristics and structural characteristics of a building, is extremely low, the building generally also has the characteristics of extremely low energy consumption, extremely high plot ratio, and extremely large volume. The present invention defines such buildings as "double-low and double-exceeding buildings".

[0061] The specific surface area of a building is the ratio of the total external surface area to the total volume of the building and is a core indicator reflecting the energy characteristics and structural characteristics of the building. A large specific surface area of a building means that the external surface area evenly distributed per unit volume of the internal space of the building is large, which is one of the fundamental reasons for high building energy consumption, more consumption of external wall materials, complex construction technology, low overall plot ratio of the building complex, and high housing prices.

[0062] Ordinary buildings have a rectangular outer contour and three-dimensional dimensions of length, width, and height. Taking a special case of a cube in a cuboid as an example, the specific surface area indicators of cube buildings of different scales are listed as follows

[0063]

[0064]

[0065] The above table shows that the specific surface area of a cube building is inversely proportional to the first power of the side length. When the side length increases from 3m to 30m and 300m respectively, its specific surface area decreases from 2 / m 2 to 0.6 and 0.06m 2 / m 2 .

[0066] The specific surface area of a building, as the ratio of the total external surface area to the total building area, is the external surface area per unit building area (1m 2The external surface area evenly distributed, that is, the area of energy exchange with the environment evenly distributed per unit building floor area within the building, namely the external surface area of the building where per unit building floor area within the building evenly distributes the heat radiation and heat convection received from the environment in summer and the heat radiation and heat convection emitted to the environment in winter. Therefore, the specific surface area is a building physical quantity reflecting the energy characteristics and structural characteristics of the building. The lower this value is, the better. The lower the specific surface area, the weaker the energy exchange intensity between the internal space of the building and the environment; and to make this value low, the building must have a large volume; because the total surface area of the building is proportional to the square of the building linear dimension, and the total building floor area is proportional to the cube of the linear dimension, so the specific surface area, which is the ratio of the total surface area of the building to the total building floor area, is inversely proportional to the linear dimension to the first power: the larger the building linear dimension, the lower the specific surface area; the smaller the building linear dimension, the higher the specific surface area.

[0067] Under the current technical conditions, the specific surface area of ordinary buildings is in the order of 1.0 m 2 / m 2 ; when the specific surface area of the building is reduced to 10 -1 m 2 / m 2 order of magnitude, that is, when only 0.1 m 2 of the external surface area is evenly distributed to the internal building floor area, it necessarily has the structural and energy characteristics of "ultra-high floor area ratio, ultra-large volume, and extremely low energy consumption". 2

[0068] Please refer to Figures 1 to 14 , the building with a ribbon-shaped viewing platform and extremely low specific surface area provided by the present invention is a large-volume or ultra-large-volume building, and its specific surface area is of the order of 10 -1 m 2 / m 2 order of magnitude or below 10 -1 m 2 / m 2 order of magnitude; the building adopts an air isolation structure with multiple flat layers 1 arranged vertically and multiple air passages arranged on each flat layer 1. The building includes several such flat layers 1. The flat layer 1 includes a connected functional space area and an edge area. There are several functional space unit groups arranged in the functional space area, and there are several air-filled passages arranged between several functional space unit groups, that is, several functional space unit groups are separated by air. Each functional space unit group includes at least one functional space unit 11;

[0069] The edge area is arranged outside the functional space area, and a ribbon-shaped viewing platform 12 is arranged in the edge area. The viewing platform is a transparent space, and the viewing platform 12 is communicated with the passage 13. The ribbon-shaped viewing platform 12, as a shared space for all members of the entire flat layer, allows all members to walk out of the office (residence), view the scenery by the window, and contact the environment.

[0070] The strip-shaped viewing platform 12 can be independent. Independent small spaces equal in number to the number of households on the same floor can be partitioned by the strip-shaped viewing platform 12 near the window. It can be in the form of booths for independent use by each household.

[0071] The strip-shaped viewing platform 12 can also be shared, connecting the independent small spaces of multiple households.

[0072] As an embodiment, please refer to Figure 1 , the edge area is wound 360° around the outside of the functional space area, and the shape of the viewing platform 12 is an annular strip. In this embodiment, the independent small spaces of multiple households can be connected and joined into a strip, surrounding the main body of the building. The members on the same floor, as experiencers, can walk through the entire annular strip-shaped viewing platform and experience the building environment 360°.

[0073] As another embodiment, please refer to Figure 2 , the shape of the viewing platform 12 is not an annular strip, but a strip-shaped strip, that is, the edge area is provided at at least one end of the functional space area.

[0074] Preferably, an edge area is provided at each of the two ends of the functional space area. In this embodiment, some tea tables and chairs 14 can also be placed on the strip-shaped strip-shaped viewing platform 12 to enclose several leisure areas as places for carrying out cultural, sports and entertainment activities.

[0075] The strip-shaped viewing platform 12 also serves as an indoor fitness landscape runway for all household members on the same floor, with a closed structure, avoiding the invasion of wind, frost, rain, snow, heat and cold on the experiencers, and improving the comfort of fitness exercise.

[0076] The strip-shaped viewing platform 12 is also open. Through the glass window, the strip-shaped viewing platform is integrated with the environment.

[0077] In the present invention, the building adopts a fresh air system 2. The fresh air system 2 sends fresh outside air into each functional space unit 11 on each floor and discharges the polluted air in each functional space unit 11 to the outside of the building.

[0078] In the present invention, the building is provided with an oil fume treatment layer and an oil fume and polluted air discharge layer.

[0079] The building of the present invention can be a residential house, an office building, a hotel, etc., without limitation here. Therefore, the functional space unit 11 can be an office, a meeting room, a storage room, a reading room, a laboratory, a lounge, a residence, etc.

[0080] The advantages of the building with a strip-shaped viewing platform and an extremely low specific surface area according to the present invention are:

[0081] 1. Meet the experience of the interaction between residents and the environment

[0082] In the present invention, viewing platforms are arranged at the edges of each floor of a building with an extremely low specific surface area, extremely low energy consumption, extremely high plot ratio, and extremely large volume, which meet the experience needs of flat-floor residents to get out of their cramped living spaces, get close to nature, and interact with the environment. A landscape fitness track is also provided for flat-floor residents;

[0083] The viewing platforms arranged at the edges of each floor of the present invention, as the shared space for all the residents on the entire floor, also break the situation where residents in traditional residential buildings keep to themselves, which is conducive to enhancing the communication and cooperation among residents and cultivating and building harmonious neighborhood relations.

[0084] 2. Greatly save land, building materials and energy

[0085] The present invention adopts an overall cubic structure for the building. Multiple super-large flat floors are arranged within the overall cubic structure, and row houses or other functional unit spaces are arranged on each super-large flat floor. The building plot ratio can be greatly increased from about 5.0 in traditional residential communities to more than 15.0, thereby realizing intensive land use for buildings, greatly saving land, and providing excellent living spaces for ordinary people under high land price conditions.

[0086] The present invention adopts an overall regular cubic or near-regular cubic structure for the building. Multiple super-large flat floors are arranged within the overall regular cubic or near-regular cubic structure, and row houses are arranged on each super-large flat floor. The protrusions and recesses on the outer facades of multiple single traditional residential buildings under the condition of equal building area are cancelled, thereby greatly saving building materials for the exterior wall, reducing the construction process difficulty and construction time, and greatly reducing the construction cost.

[0087] The present invention adopts an overall regular cubic or near-regular cubic structure for the building. Multiple super-large flat floors are arranged within the overall regular cubic or near-regular cubic structure, and row houses are arranged on each super-large flat floor, which reduces the overall specific surface area index of the building to an extremely low level, presenting the architectural characteristics of an extremely large volume, extremely high plot ratio, and extremely low specific surface area. The exterior wall area for the building to exchange energy with the environment per unit floor area of the residence, that is, the area for the building to receive environmental heat radiation in summer and emit heat radiation to the environment in winter, is reduced to the lowest level, constructing a truly green and low-carbon building, greatly saving building energy consumption which has become one of the three major main forces of the total social energy consumption and accounts for as high as 20%. In high-latitude regions, more than 3 / 4 of the heating and ventilation energy consumption of residences can be saved, which is of great significance for reducing the total social carbon emissions.

[0088] 3. The secondary scenery conditions index inside the building is better than the natural environment

[0089] In terms of specific individual living conditions of humans, the artificial secondary environment is superior to the original ecological environment, and this value judgment has been verified many times: multi-story and high-rise concrete residences are superior to caves, tap water is superior to the original ecological river water and groundwater, and flush toilets are superior to latrines; especially after the emergence of energy technologies such as artificial fire and air conditioners, cooked food at high temperatures is superior to eating raw meat and drinking blood, semiconductor lighting is superior to sunlight radiation, the air-conditioning wind after cooling and dehumidifying in summer is superior to the ambient hot wind, and floor heating in winter is superior to open fires in the wild.

[0090] A space, as long as it can keep out wind and rain, can provide clean fresh air, suitable lighting, clean drinking water and sanitary hot water, stable electricity and network signals, and can smoothly discharge dirty air, excrement and garbage, it is a livable residence.

[0091] The present invention relates to a building with an extremely low specific surface area provided with a strip-shaped viewing platform. The indoor fresh air replacement and the treatment and discharge diffusion effect of dirty air and kitchen fumes have reached the extreme. The temperature and humidity, oxygen content, cleanliness, noise, light intensity, light softness and other indicators of the secondary artificial scenery environment inside the building are all superior to the original natural environment; and there are no more mosquito troubles in the residence; new technologies and new products such as real-time outdoor scene images, air-flow closed-loop circulation dehumidifying drying heat pumps, gas-free electric kitchens, and semiconductor cold light source lighting can also be introduced into the building to create secondary climate conditions and living conditions that originate from the natural environment and are superior to the natural environment.

[0139] Embodiment 7

[0140] The present invention does not limit the number of functional space units included in a functional space unit group. In this embodiment, taking the functional space unit group including four functional space units as an example, the main parameters of the building are as follows:

[0141] Total land area: 17500 m 2 ; Greening rate: 60%; Building land area: 6988.6 m 2 ;

[0142] The overall shape of the building is nearly a regular cube. The column spacing of the building structure is 10 m in the north - south direction and 7 m in the east - west direction; the floor height is 3 m, the total floor height above the ground is 40 floors, 120 m. The side length of the flat floor in the north - south direction is 84.2 m, the side length in the east - west direction is 83 m, and the total area of the flat floor is 6988.6 m 2 ; Total building area: 333,000 m 2 (including two basement floors);

[0143] Each flat floor is composed of 4 flat - floor modules. The southeast, northeast, southwest, and northwest sub - modules are bounded by the north - south central passage; each module is centered on the vertical passage composed of the elevator and stairs in this module, and includes 2 groups of 4 rows of 16 sets of residences, including two housing type structures of 8.2 m * 7 m and 10 m * 7 m; in the 10 m * 7 m structural unit, a 1.8 m horizontal air supply duct is separated to set up the 8.2 m * 7 m small - sized housing type.

[0144] Total number of households: 2560; Total number of people: 8960;

[0145] Plot ratio: 16.0; Total specific surface area: 0.195 m 2 / m 2 ;

[0146] Fresh air volume: According to 3.5 people per household, each person needs 30 m of fresh air per hour 3, during holidays, everyone stays indoors all day and night. Gas is prohibited for cooking activities, and only electric cookers can be used. The fresh air consumption for cooking is calculated by referring to 0.5 times the fresh air volume per person. Accordingly, the maximum fresh air demand for a flat floor in 24 hours is measured to be 242,000 m 3 , that is, 10,000 m 3 / h; The maximum fresh air demand for the entire 40-story large-scale residential building in 24 hours is 9.68 million m 3 , that is, 400,000 m 3 / h;

[0147] Fresh air pretreatment heat load: According to the calculation of reducing the outdoor fresh air of the building by 20°C for cooling and dehumidification in summer and heating the fresh air by 20°C in winter and the above fresh air volume, the maximum fresh air pretreatment heat load required for a flat floor is 67 kw;

[0148] According to the conversion of the cop of the refrigeration device (heat pump) being 3.0, the power consumption for fresh air pretreatment of each flat floor is 22.3 kw, and the maximum power consumption required for fresh air pretreatment of the entire building is 892 kw; The maximum daily fresh air pretreatment energy consumption per person is 2.4 kwh; Considering factors such as no need for cooling and dehumidification or heating in spring and autumn seasons and family members leaving home for work, the annual average fresh air energy consumption per person is less than half of the above value, that is, less than 1.2 kwh / day.

[0149] In this embodiment, for a building with a very low specific surface area provided with a strip-shaped viewing platform, during the operation process, in addition to the fresh air pretreatment energy consumption, there is also the air-conditioning energy consumption of the residents.

[0150] For a building with a very low specific surface area provided with a strip-shaped viewing platform in this embodiment, please refer to Figures 1 to 5 As shown, there are multiple air isolation layers in the vertical direction; 16 functional space unit groups are set on each flat floor. These 16 functional space unit groups are independent of each other, and there are air aisles between them, thus creating an air-separated physical structure with multiple vertical layers and multiple horizontal air aisles; In the air heat exchange process of this embodiment, all three ways of air convection heat transfer, heat conduction, and heat radiation are playing roles. However, due to the effects of multiple vertical air isolation layers and multiple horizontal air isolation aisles in the building, these three heat transfer methods are very weak, thus significantly reducing the air-conditioning energy consumption of the residents compared with traditional residences.

[0151] In the air convection heat transfer of this embodiment, since the fresh air volume is still very small relative to the large-scale building, there is only 10,000 m 3 / h for each flat floor, that is, 3 m 3 / s. Except for the relatively fast air flow velocity at the fresh air inlet and the dirty air outlet, the fresh air flow velocity in the main space of the building is very small, only 10 -2At the m / s level, similar to the air microclusters confined in the pores of lightweight foam materials, in a static or quasi-static state with an approximate speed of zero, air convection heat transfer can be ignored;

[0152] For the air heat conduction in this embodiment, since the thermal conductivity of air at room temperature is 0.024 W / (m·K), which is only 4.4% of 0.54 W / (m·K) of water, it is also very weak; in fact, in terms of heat conduction, air is a poor conductor of heat. The excellent insulation effects of various foamed materials such as polyurethane foam boards, aerated concrete blocks for walls, and even cotton-padded jackets and quilts all come from the air bubbles with heat insulation properties in these materials;

[0153] For the air thermal radiation in this embodiment, except for the relatively strong thermal radiation (heat absorption) between the exterior facade of the building and the ambient atmosphere due to the large temperature difference in summer and winter, the air thermal radiation inside the building is also very weak.

[0154] Based on the above analysis, for a building with a ribbon-shaped viewing platform and an extremely low specific surface area in this embodiment, the average annual per capita fresh air energy consumption is less than 1.2 kWh / day; at the same time, since this embodiment adopts an extremely large volume and nearly cube-shaped structure, it has a significant energy-saving effect for buildings with an extremely low specific surface area; and due to the air isolation physical structure with multiple horizontal layers vertically arranged in the building in this embodiment and multiple air passages arranged horizontally in each horizontal layer, during the operation process, the air heat convection, heat conduction, and thermal radiation inside the building are all very weak. In short, the energy exchange between each household and the environment is further reduced; for each household in each functional space unit group of each horizontal layer in this embodiment, the self-heat release of the indoor residents and cooking heating in winter can compensate for the weak heat leakage of the residence to the environment to maintain the indoor temperature, and in summer, only the self-heat release of the residents, cooking heating, and the extremely low heat leakage from the environment need to be removed to maintain the indoor temperature. As a result, the air-conditioning energy consumption of the households in this embodiment is significantly reduced by more than 3 / 4 compared with that of traditional residences. The energy-saving amplitude and effect are far beyond the reach of the energy-saving amplitude and effect achieved by improving the thermal insulation performance of building materials and the performance of air-conditioning and heating ventilation equipment.

[0155] The present invention adopts a vertical multi-layer and horizontal multi-air passage air isolation physical structure with multiple flat layers arranged vertically and multiple air passages arranged in each flat layer. Starting from the concepts of the specific surface area of a building and a double-low and double-super building, it breaks through the existing building design specifications, adopts excellent artificial ventilation technology to replace traditional natural ventilation, solves the ventilation problems of large-scale and ultra-large-scale buildings, that is, the problems of fresh air entering and dirty air exhausting, realizes the technical goals of increasing the three-dimensional scale of the building, increasing the building volume, reducing the specific surface area, and increasing the floor area ratio, makes the design and construction of "double-low and double-super" buildings with extremely low specific surface area, extremely low energy consumption, extremely high floor area ratio, and ultra-large scale a reality, and makes green residences desired by ordinary families within reach under the background of high land prices.
