Description

The present invention relates to a double-skin structure of a building.

Conventionally, a double-skin structure of a building having an inner side surface material arranged on the indoor side and an outer surface material arranged on the outdoor side of the inner side surface material at intervals is known. In the conventional double-skin structure, the vision part and the spandrel part of the outer surface material are arranged with a single piece of glass, float glass is used for the outer surface material, and Low-E glass is used for the vision part of the inner side surface material. The outside air load was reduced (insulated) with the double glazing that had been used (see Patent Document 1).

Japanese Unexamined Patent Publication No. 2015-214788

However, in the conventional double-skin structure, Low-E glass was used for the inner side surface material in order to reduce the load on the outside air (to secure the indoor environment of the perimeter part) as described above, but the product cost is high. There was a problem.

On the other hand, in the double-skin structure, if both the outer surface material and the inner surface material use a surface material having low heat insulating performance such as float glass, the outside air load cannot be reduced and the indoor environment (particularly the perimeter part) affects the cooling. / There was a risk that the heating efficiency would decrease.
Against this background, in recent years, it has been desired to realize a double-skin structure that can optimally secure an indoor environment.

Therefore, the present invention has been made in view of the above circumstances, and an object of the present invention is to provide a double-skin structure of a building in which an indoor environment can be suitably secured.

In the double-skin structure of the building of the present invention, an inner surface material provided on the outer wall portion of the building and arranged on the indoor side and an outer surface material arranged on the outdoor side of the inner side material at intervals are provided. In the double-skin structure of the building provided, the horizontal partition extending in the horizontal direction so as to partition the hollow layer between the inner side surface member and the outer surface member, and the horizontal partition portion adjacent to each other in the vertical direction. The enclosed hollow layer is provided with an air-conditioned air supply unit that supplies air-conditioned air in the room and discharges carbon dioxide in the room to the outside. A ventilation unit and an opening / closing mechanism for opening and closing the outdoor ventilation unit are provided , and the outer surface material is made of a single-plate float glass and the inner side surface material is made of double glazing made of float glass. It is a feature.

According to the double-skin structure of the building of the present invention, the hollow layer between the inner side surface material and the outer surface material is provided with an conditioned air supply unit that supplies conditioned air in the room, and the horizontal partition portion that partitions the hollow layer is outdoors. It is equipped with a ventilation unit and its opening / closing mechanism.
Therefore, if the hollow layer and the outside are communicated by the opening / closing mechanism and the indoor air-conditioned air is supplied to the hollow layer by the air-conditioned air supply unit, the inside of the hollow layer can be ventilated by the air-conditioned air, and the inside of the hollow layer can be ventilated by the air-conditioned air. Can be maintained at a temperature corresponding to the temperature of.

As a result, the temperature difference between the room (perimeter portion) and the hollow layer can be reduced or eliminated, and the indoor environment of the perimeter portion can be suitably secured. Further, since a predetermined amount of the conditioned air in the room can be discharged to the outside through the hollow layer, the energy efficiency can be improved and the conditioned air can be effectively discharged to the outside.

At that time, the air in the hollow layer that has been raised or lowered by the sunlight or the outside air temperature can be replaced with air-conditioned air. Moreover, since the horizontal section that divides the hollow layer up and down is equipped with an outdoor ventilation section, the air that stays in the vicinity of the horizontal section due to the temperature rising and falling in the hollow layer can be removed. It can be efficiently discharged outdoors.

Further, since the air-conditioned air supplied into the hollow layer is discharged to the outside through the outdoor ventilation unit, it is not necessary to circulate the temperature-adjusted air in the hollow layer to the air-conditioning equipment to perform air-conditioning. Moreover, it is necessary to discharge a part of the conditioned air to the outside in order to keep the carbon dioxide concentration in the room below a predetermined value. Therefore, the conditioned air may be supplied from the conditioned air supply unit to the hollow layer and discharged to the outside, and the conditioned air can be effectively discharged to the outside through the hollow layer.

As a result, the indoor environment of the perimeter portion adjacent to the hollow layer can be suitably secured via the inner side surface material. As a result, it is possible to efficiently maintain the indoor temperature stably by utilizing the heat of the conditioned air discharged from the room to the outside in order to maintain the indoor environment.
Therefore, according to the present invention, it is possible to provide a double-skin structure of a building capable of effectively discharging conditioned air to the outside while appropriately securing an indoor environment.

In the present embodiment, the horizontal partition 30 is provided at a position facing the floor slab 15 of each floor, and the hollow layer 23A of the upper floor 19A and the hollow layer 23B of the lower floor 19B are partitioned by the horizontal partition 30. ing.

Further, the hollow layer 23 is provided with a plurality of vertical members 24 extending in the vertical direction at intervals in the horizontal direction. The vertical member 24 of the present embodiment is a mullion and does not partition the hollow layer 23. The vertical member 24 may partition the hollow layer 23 in the left-right direction.

Further, the communication passage 34 is provided with an opening / closing mechanism 35 for opening and closing the communication passage 34.

In the present embodiment, there are two types of outdoor ventilation units 31, and one of the outdoor ventilation units 31 is provided in the horizontal section 30.

The upper floor horizontal section 30A and the lower floor horizontal section 30B are arranged on the same floor so that the numbers or the opening areas of the outdoor ventilation ports 32 are substantially equal. For example, as shown in FIG. 3, in the same layer, one horizontal section 30 is provided between a pair of vertical members 24, 24 adjacent to each other in the horizontal direction, and here, the horizontal section 30A for the upper floor and the lower floor are provided. Horizontal compartments 30B are arranged alternately. In other words, the term "substantially equal" as used herein means that when the upper floor horizontal compartment 30A and the lower floor horizontal compartment 30B are all formed to have the same size (volume), the number of installations thereof is approximately the same. It means that they are the same. In addition, when the shapes of the horizontal section 30A for the upper floor and the horizontal section 30B for the lower floor are different (or when the shape must be different from the others depending on the installation location), "substantially equal" means the upper part. It means that the total opening area of the outdoor ventilation port 32 of the horizontal section 30A for the floor and the total opening area of the outdoor ventilation port 32 of the horizontal section 30B for the lower floor are substantially equivalent.

In the present embodiment, as further shown in FIG. 2, a plurality of horizontal compartments 30 arranged vertically at intervals between the pair of vertical members 24, 24 are provided with outdoor ventilation portions 31 of different types. The upper floor horizontal section 30A and the lower floor horizontal section 30B are arranged alternately in the vertical direction.
That is, the space of the hollow layer 23 is partitioned by the horizontal compartments 30 (30A, 30B) as shown by the alternate long and short dash line in FIG.

As shown in FIG. 4, in the horizontal section 30A for the upper floor, the outdoor ventilation port 32 of the outdoor ventilation section 31 is continuously provided in the garage 27 arranged so as to face the outdoor 14. The hollow layer ventilation port 33 is arranged upward so as to face the hollow layer 23 on the upper floor.

As shown in FIG. 5, in the lower floor horizontal section 30B, the outdoor ventilation port 32 of the outdoor ventilation section 31 is connected to the gallery 27 arranged so as to face the outdoor 14. The hollow layer ventilation port 33 is arranged downward so as to face the hollow layer 23 on the lower floor. The communication passage 34 is a flow path that communicates the outdoor ventilation port 32 on the gallery 27 side and the hollow layer ventilation port 33 on the hollow layer 23 side. The communication passage 34 is configured to rise upward from the outdoor ventilation port 32, extend horizontally from the upper end, descend downward from the tip on the indoor side, and open to the hollow layer 23 on the lower floor.
The communication passage 34 is provided with an opening / closing mechanism 35 for opening / closing the communication passage 34. The opening / closing mechanism 35 is configured to be able to open / close between the outdoor ventilation port 32 and the hollow layer ventilation port 33 by operating the valve body 36.

The opening / closing mechanism 35 in the outdoor ventilation section 31 of the upper floor horizontal section 30A and the lower floor horizontal section 30B may be opened / closed manually or automatically. In the form, it is configured to be opened and closed according to the operating condition of the air conditioning equipment in the room 13.
Further, the opening / closing mechanism 35 is configured to open / close according to the outside air temperature when the air conditioning equipment in the room 13 is stopped.

The air-conditioning equipment is provided with an air conditioner (not shown) that takes in air and outside air from the room 13, exchanges heat, and blows them out into the room 13, and is provided in a hollow layer 23 surrounded by horizontal compartments 30 adjacent to each other in the vertical direction. The conditioned air supply unit 25 for supplying the conditioned air of 13 is provided.

The conditioned air supply unit 25 takes in the conditioned air in the room 13 from, for example, a ventilation port (exhaust port) arranged in the ceiling panel 16 and pumps it by a pressure feeding means such as a ventilation fan and a duct 26 to form an inner side surface member 21. It is configured to supply to the hollow layer 23 from the supply opening 28 provided above. The duct 26 is provided with a damper (not shown) so that the damper is opened when the air conditioner is operating (during air conditioning) and closed when the air conditioner is stopped. That is, the air conditioning air is supplied to the hollow layer 23 when the air conditioner is operated, and the air in the room 13 is not supplied to the hollow layer 23 when the air conditioner is stopped. When the air conditioner is started, the ventilation fan provided in the duct 26 is also started at the same time to supply cold air and warm air to the hollow layer 23. When the operation is stopped, the ventilation fan is stopped and the damper is closed. It is configured as follows. It is not necessary to install the damper and the ventilation fan described above, and the opening / closing timing of the damper and the operation timing of the ventilation fan can be adjusted as appropriate.

Next, the operation of the double-skin structure 11 of the building 10 having such a configuration will be described.
FIG. 6 is a diagram for explaining the operation during the heating operation, FIG. 7 is a diagram for explaining the operation during the cooling operation, FIG. 8 is a diagram for explaining the operation when the operation of the air conditioner is stopped in the summer and the intermediate period, and FIG. 9 is a diagram for explaining the operation when the operation of the air conditioner is stopped. It is a figure explaining the operation when the operation of an air conditioner is stopped in winter.

First, when the air-conditioning equipment is in the heating operation in winter, as shown in FIG. 6, the room 13 is supplied with air-conditioned air for heating having a temperature higher than the outside air temperature. A part of the conditioned air can be supplied from the chamber 13 to the hollow layer 23 from the duct 26 by the conditioned air supply unit 25 via, for example, a ventilation fan (not shown).
On the other hand, in the hollow layer 23, since the operating condition of the air conditioning equipment is heating operation, the opening / closing mechanism 35 of the upper floor horizontal compartment 30A is open and the opening / closing mechanism of the lower floor horizontal compartment 30B is open according to this operating condition. The opening and closing drive is performed so that the 35 is in the closed state. Therefore, in the hollow layer 23, the upper floor 19A side is closed, and the lower floor 19B side is communicated with the outdoor 14 by the communication passage 34.

For example, when the air conditioning air for heating operation is supplied to the hollow layer 23 from the duct 26 in a state where the room 13 has reached a predetermined temperature, the opening / closing mechanism 35 of the horizontal compartment 30B for the lower floor is closed, so that the air conditioning is performed. Air gradually accumulates in the upper part of the hollow layer 23, and the air cooled by the outside air in the hollow layer 23 moves below the hollow layer 23 and continues from the hollow layer ventilation port 33 of the horizontal compartment 30A for the upper floor. It moves to the outdoor ventilation port 32 through the passage 34, and is discharged from the garage 27 to the outdoor 14.
As a result, warm air accumulates around the vision portion of the hollow layer 23, and the vision portion of the hollow layer 23 can be maintained warmer than the outside air temperature, while the air cooled by the outside air is discharged from the garage 27 to the outside. .. Therefore, since the temperature difference between the chamber 13 and the hollow layer 23 can be reduced, the hollow layer does not have to have a high heat insulating specification such as Low-E double glazing filled with krypton gas for the inner side surface material 21. By warming 23, the heating efficiency of the room 13 can be improved. Of course, if the inner side surface material 21 has a high heat insulation specification, the heating efficiency is further improved.

As a result, the hollow layer 23 is maintained in a temperature state higher than the outside air temperature by the heating air while preventing an increase in the carbon dioxide concentration in the room 13, and the temperature environment of the room 13 (perimeter portion) can be suitably secured. it can.

Next, when the air-conditioning equipment is in the cooling operation in the summer, as shown in FIG. 7, the air-conditioned air having a cooling temperature lower than the outside air temperature is supplied to the room 13. A part of the conditioned air is supplied from the duct 26 to the hollow layer 23 near the ceiling panel 16 which is the upper part of the hollow layer 23 by the conditioned air supply unit 25 from the room 13 via, for example, a ventilation facility. The conditioned air supply unit 25 may be provided with, for example, a damper (not shown) so that the timing and amount of supply of the conditioned air to the hollow layer 23 can be adjusted.
On the other hand, in the hollow layer 23, since the operating condition of the air conditioning equipment is cooling operation, the opening / closing mechanism 35 of the upper floor horizontal compartment 30A is closed and the opening / closing mechanism of the lower floor horizontal compartment 30B is closed according to this operating condition. The opening and closing drive is performed so that the 35 is in the open state. Therefore, in the hollow layer 23, the lower floor 19B side is closed, and the upper floor 19A side is communicated with the outdoor 14 by the communication passage 34.

In this state, when air-conditioned air for cooling operation is supplied to the upper part of the hollow layer 23 from the duct 26, the warmed air in the hollow layer 23 moves upward and reaches the outdoor ventilation port 32 via the communication passage 34. Since the opening / closing mechanism 35 of the horizontal section 30A for the upper floor is in the closed state after being discharged, the cold air supplied from the duct 26 accumulates below the hollow layer 23. Then, warmed air accumulates above the cold air accumulated in the hollow layer 23, but moves from the hollow layer ventilation port 33 of the lower floor horizontal section 30B to the outdoor ventilation port 32 through the communication passage 34. It is released to the outside from the gallery 27. Therefore, since cold air is collected in the vision portion of the hollow layer 23 by the temperature difference ventilation, the temperature difference between the hollow layer 23 and the room 13 can be reduced, and the cooling efficiency is improved.

As a result, the hollow layer 23 is maintained in a temperature state lower than the outside air temperature by the cooling air while preventing an increase in the carbon dioxide concentration in the room 13, and the temperature environment of the room 13 (perimeter portion) can be suitably secured. it can.

Next, as shown in FIG. 8, when the air conditioning equipment is stopped in the summer and the intermediate period (for example, at night), the air conditioning air is not supplied to the room 13. Further, the air conditioning air supply unit 25 is also stopped, and air is not supplied from the duct 26 to the hollow layer 23.
On the other hand, in the hollow layer 23, since the operation status of the air conditioning equipment is stopped, the opening / closing mechanism 35 of the upper floor horizontal compartment 30A is open and the opening / closing mechanism of the lower floor horizontal compartment 30B is open according to the outside air temperature. 35 is also driven to open and close so as to be in the open state. Therefore, in the hollow layer 23, both the lower floor 19B side and the upper floor 19A side are communicated with the outside by the communication passage 34. Regarding the drive of the opening / closing mechanism 35, a predetermined threshold value may be set with respect to the outside air temperature, and if the threshold value or more is set, the two opening / closing mechanisms 35 may be set to be in the open state together. Alternatively, as another method, the temperature difference between the outside air temperature and the room temperature may be measured, and the opening / closing mechanism 35 may be set to be driven according to the temperature difference.

In this state, outside air flows in from the outdoor ventilation port 32 of the horizontal section 30A for the upper floor through the communication passage 34 and is taken into the hollow layer 23, and the relatively warm air in the hollow layer 23 becomes an updraft. It moves above the hollow layer 23, flows from the hollow layer ventilation port 33 of the lower floor horizontal section 30B to the outdoor ventilation port 32 through the communication passage 34, and is discharged from the garage 27 to the outside. As a result, the outside air flows into the hollow layer 23 and the air inside the hollow layer 23 is moved, so that the temperature rise of the hollow layer 23 can be suppressed.

Next, as shown in FIG. 9, when the air conditioning equipment is stopped in winter (for example, at night), the air conditioning air is not supplied to the room 13. Further, the air conditioning air supply unit 25 is also stopped, and air is not supplied from the duct 26 to the hollow layer 23.
On the other hand, in the hollow layer 23, since the operation status of the air conditioning equipment is stopped, the opening / closing mechanism 35 of the upper floor horizontal compartment 30A is closed and the opening / closing mechanism of the lower floor horizontal compartment 30B is closed according to the outside air temperature. 35 is also driven to open and close so as to be in a closed state. Therefore, the hollow layer 23 does not communicate outdoors with both the lower floor 19B side and the upper floor 19A side closed.

In this state, since the air in the hollow layer 23 comes into contact with the outside air via the outer surface material 22, the temperature inside the hollow layer 23 may decrease, but on the other hand, the air in the hollow layer 23 is on the inner surface. It is in contact with the indoor air via the material 21.
As a result, the temperature drop of the hollow layer 23 can be suppressed, and the temperature drop of the room 13 (perimeter portion) can be suppressed.

According to the double-skin structure 11 of the building 10 of the present embodiment as described above, the air-conditioned air supply unit 25 that supplies the air-conditioned air of the room 13 to the hollow layer 23 between the inner side surface material 21 and the outer surface material 22 is provided. The horizontal partition 30 for partitioning the hollow layer 23 is provided with an outdoor ventilation port 32 and a hollow layer ventilation port 33, a communication passage 34 communicating these, and an opening / closing mechanism 35 thereof.
Therefore, if the hollow layer 23 and the outdoor 14 are communicated with each other by the opening / closing mechanism 35 and the conditioned air in the room 13 is supplied to the hollow layer 23 by the conditioned air supply unit 25, the inside of the hollow layer 23 can be filled with the conditioned air. , The inside of the hollow layer 23 can be maintained at a temperature corresponding to the temperature of the conditioned air.

For example, at the time of heating, the temperature inside the hollow layer 23 tends to decrease because the outdoor 14 is lower than the indoor 13, but the hollow layer 23 is exhausted while supplying the conditioned air for heating from the indoor 13 to the hollow layer 23. It is possible to suppress the temperature drop. On the other hand, at the time of cooling, the temperature of the outdoor 14 tends to rise because the temperature of the outdoor 14 is higher than that of the indoor 13, but the temperature of the hollow layer 23 rises because the air conditioning air for cooling is supplied to the hollow layer 23 from the indoor 13 and exhausted. Can be suppressed.
Further, since the hollow layer 23 is configured to exhaust air from below to the outside 14 during heating and exhausts to the outside 14 from above during cooling, the hollow layer 23 exchanges indoor and outdoor air. The inside can be a buffer space.
As a result, the temperature difference between the indoor 13 and the hollow layer 23 adjacent to each other via the inner side surface member 21 can be reduced or eliminated, and the temperature environment of the indoor 13 (perimeter portion) can be suitably secured. ..

In other words, the air in the hollow layer 23, which rises or falls in temperature due to sunlight, outside air temperature, or the like, can be replaced with air-conditioned air. Moreover, since the outdoor ventilation port 32 and the hollow layer ventilation port 33 are provided in the horizontal section 30 that divides the hollow layer 23 vertically, the temperature rises or falls in the hollow layer 23. The air staying in the vicinity of the horizontal compartment 30 can be efficiently discharged to the outdoor 14.

Further, since the conditioned air supplied into the hollow layer 23 is discharged from the hollow layer ventilation port 33 through the communication passage 34 to the outdoor ventilation port 32 to the outdoor 14, the air after the temperature in the hollow layer 23 is adjusted is used as the air conditioning equipment. There is no need to circulate and air-condition.
Moreover, according to the Building Sanitation Management Law, it is necessary to discharge a part of the conditioned air to the outdoors 14 in order to keep the carbon dioxide concentration in the room 13 below a predetermined value. Therefore, by supplying the conditioned air that must be discharged from the conditioned air supply unit 25 to the hollow layer 23 and discharging it to the outdoor 14, the temperature of the hollow layer 23 can be easily and efficiently adjusted, and the discharged conditioned air can be adjusted. It can be used effectively.

As a result, the temperature difference between the hollow layer 23 adjacent to each other via the inner side surface member 21 and the room 13 (perimeter portion) can be reduced. As a result, in order to maintain the environment of the indoor 13 (perimeter part), the heat energy of the conditioned air discharged from the indoor 13 to the outdoor 14 is effectively used, and the outdoor 14 does not have to have the inner side material 21 with high heat insulation specifications. It is possible to suppress the inflow and outflow of heat from the air conditioner, and it is possible to efficiently maintain the indoor temperature in a stable manner.

In the present embodiment, by providing the above configuration, single plate glass or float glass is used as the outer surface material 22, and double glazing composed of two float glasses is used as the inner side surface material 21. Even if a low face material (glass) is used, the indoor environment can be preferably secured. In other words, it is not necessary to improve the heat resistance (heat insulating property) of the inner side surface material 21 and the outer surface material 22 due to the sunlight and the outside air temperature, and the load on the air conditioner does not increase.

Therefore, according to the double-skin structure 11 of the building of the present embodiment, it is easy to efficiently maintain the indoor temperature stably while suppressing the cost. Further, float glass can be used for the inner side surface material 21 and the outer surface material 22, and the appearance and the appearance from the indoor side can be improved. Further, the outer surface material 22 can be arranged without being separated into the vision portion and the spandrel portion, and the appearance can be improved in that respect as well.
In other words, by maintaining the hollow layer 23, which is easily affected by the outside air, at an appropriate temperature in summer or winter, the energy used for the air conditioner for cooling / heating the room 13 can be saved, and the outer surface material 22 can be used. And the heat insulating property or heat resistance of the inner side surface material 21 does not have to be a high-performance fitting.

Further, according to the double-skin structure 11 of this embodiment, the horizontal partition portion 30A for the upper floor where the hollow layer ventilation port 33 is formed only on the upper floor and the lower floor where the hollow layer ventilation port 33 is formed only on the lower floor. The floor horizontal compartments 30B and the floor horizontal compartments 30B are arranged substantially evenly on the same floor. Therefore, when the horizontal section 30A for the upper floor and the horizontal section 30B for the lower floor are provided substantially evenly, the air that has risen in temperature in the hollow layer 23 is exhausted from the upper floor 19A side of the hollow layer 23. However, even when the air that has been lowered and lowered in the hollow layer 23 is exhausted from the lower floor 19B side, it can be exhausted in the same manner. Therefore, the air conditioning equipment can be operated stably during both heating and cooling.

Further, according to the double-skin structure 11 of the present embodiment, the horizontal compartments 30A for the upper floors and the horizontal compartments 30B for the lower floors are alternately arranged in the same floor, so that the hollow layer formed only on the upper floors. The ventilation port 33 and the hollow layer ventilation port 33 formed only on the lower floor can be surely provided substantially equal on the upper floor side and the lower floor side of the hollow layer 23.

Further, according to the double skin structure 11 of the present embodiment, even if a plurality of hollow layers 23 are partitioned in the vertical direction, the horizontal compartments 30A for the upper floor and the horizontal compartments 30B for the lower floor are alternately arranged in the vertical direction. Therefore, the hollow layer ventilation port 33 formed only on the upper floor side and the hollow layer ventilation port 33 formed only on the lower floor side are surely placed on the upper floor 19A side and the lower floor 19B side of the hollow layer 23. Can be provided substantially equivalent to. As a result, the same ventilation can be achieved regardless of whether the air is exhausted from the upper floor 19A side during cooling or the lower floor 19B side during heating.

Further, according to the double-skin structure 11 of the present embodiment, two types of horizontal compartments 30 are set: the horizontal compartment 30A for the upper floor and the horizontal compartment 30B for the lower floor. Since only one opening / closing mechanism 35 is arranged in one horizontal section 30, the control for driving the opening / closing mechanism 35 can be simplified and the cost can be suppressed.

In the double-skin structure 11 of the present embodiment, the opening / closing mechanism 35 opens / closes according to the operating status of the air-conditioning equipment in the room 13, so that, for example, during cooling, the communication passage 34 of the horizontal compartment 30A for the upper floor is closed and the lower floor is closed. The communication passage 34 of the horizontal compartment 30B is opened, and the conditioned air in the room 13 is supplied from the conditioned air supply unit 25 to the hollow layer 23. As a result, while the air cooled by the air conditioner is accumulated in the hollow layer 23, the air in the hollow layer 23 whose temperature has risen due to the sunlight or the outside air temperature can be easily discharged to the outdoor 14 from above, and the hollow layer 23 and the indoor 13 ( The temperature difference with the perimeter part) can be reduced.

On the other hand, at the time of heating, the communication passage 34 of the lower floor horizontal division 30B is closed, the communication passage 34 of the upper floor horizontal division 30A is opened, and the conditioned air in the room 13 is supplied from the air conditioning air supply unit 25 to the hollow layer 23. can do. As a result, the air in the hollow layer 23, which has been cooled by the outside air temperature and whose temperature has dropped, can be easily discharged to the outdoor 14 from below, and the temperature difference between the hollow layer 23 and the indoor 13 (perimeter portion) can be reduced.
Therefore, the temperature difference between the hollow layer 23 and the room 13 can be easily reduced during both heating and cooling, and the room temperature can be kept stable.

Further, in the double skin structure 11 of the present embodiment, when the air conditioning equipment in the room 13 is stopped, the opening / closing mechanism 35 opens / closes according to the outside air temperature. Therefore, when the outside air temperature is high, for example, the upper floor horizontal It can be set to open the communication passage 34 of the division portion 30A and the communication passage 34 of the horizontal division portion 30B for the lower floor. As a result, the air in the hollow layer 23 whose temperature has risen due to the outside air temperature can be discharged from above the hollow layer 23 to the outdoor 14, and the temperature rise in the indoor 13 (perimeter portion) can be suppressed.

On the other hand, when the outside air temperature is low, for example, the communication passage 34 of the upper floor horizontal section 30A and the communication passage 34 of the lower floor horizontal section 30B can be set to be closed. As a result, it is possible to suppress the outside air from directly entering the hollow layer 23, and it is possible to suppress the temperature drop in the hollow layer 23. As a result, the temperature drop in the room 13 (perimeter portion) can be suppressed.
Therefore, the temperature difference between the hollow layer 23 and the room 13 can be reduced as much as possible regardless of whether the outside air temperature is high or low, and the indoor environment can be suitably secured.
