Description

  The present invention relates to a building in which an intermediate floor is provided above a part of a floor of a specific floor, and a lower portion of the intermediate floor is a storage space having a ceiling height of 0.9 m to 1.4 m.

In recent years, with the development of air conditioning equipment, air conditioning equipment is used for air conditioning. Therefore, in a building such as a house, in order to enhance the air conditioning effect, to prevent indoor and outdoor air from entering and exiting, to prevent indoor heat from leaking to the outside, and to reduce energy loss in the air conditioning inside the building Highly airtight and highly heat-insulated buildings with high indoor airtightness and heat insulation are used.
On the other hand, such a highly airtight and highly insulated building blocks ventilation and exit of the indoor and outdoor air, and therefore requires sufficient ventilation. Therefore, in order to ventilate a highly airtight and highly insulated building, a central ventilator that collectively ventilates a plurality of partitioned spaces such as a room in the building is used (for example, see Patent Document 1).
Japanese Patent Laid-Open No. 11-344253

However, when such a ventilator is used, there is a problem that the installation of the ventilator is costly and a lot of energy is consumed. For this reason, especially in the season when the climate is good, such as spring and autumn, open the windows and doors of each room and introduce outside air into the building without using the air conditioning equipment and ventilation equipment as described above. Natural ventilation is performed by replacing the internal air.
However, because warm air has the property of rising, warm air accumulates near the ceiling of each room simply by opening the windows and doors in each room, making it difficult to ventilate efficiently. It was. For this reason, development of the technique which can perform natural ventilation efficiently in buildings, such as a house, was desired.

  The subject of this invention aims at providing the building which can perform natural ventilation efficiently.

In the first aspect of the invention, for example, as shown in FIGS. 1 to 3, an intermediate floor 30 is provided above a part of the floor 20 of the specific floor 1 a, and the ceiling height is below the intermediate floor 30. In the building 1 which is a storage space 3 of 0.9m to 1.4m,
