Description

  The present invention relates to a microclimate design building that effectively uses a microclimate, and more particularly, to a microclimate design building excellent in ventilation and exhaust heat.

  Traditionally, traditional houses, such as thatched roof houses, have used organic energy to form organic and continuous buildings. In traditional private houses, it has been important to control the natural wind by planting a mansion forest around the building that creates the coolness of winter windbreaks and transpiration of trees in summer. In addition, in a structure with pillars and beams like a traditional private house, it is possible to easily secure the entrance and exit of the wind by providing a large opening such as a shoji and door that can be moved freely. It was possible to guide the wind into the room and spend it comfortably.

On the other hand, in recent years, buildings such as houses have been improved in heat insulation and airtightness in order to spend summer and winter comfortably. For example, in a unit type building formed by combining a plurality of building units, there is one in which an opening for ventilation is provided in a structural material constituting a framework of the unit type building (see Patent Document 1). In this unit type building, in addition to the air from the gaps between the building units, a lot of air is taken in from the opening provided in the structural material, so that ventilation and exhaust heat inside the building are sufficiently performed.

  However, there is a problem that the inside and outside of the building are shut off by improving the heat insulating and airtight performance, and only the indoor environment is controlled by the equipment that depends on resource energy. As a result, we were able to have a comfortable and convenient living environment, but the consumption of household energy has more than doubled in the last 30 years, which has a major impact on the global environment. Yes. In addition, depending on the equipment, the inhabitant's internal environment is not adapted to the homogeneous indoor environment, and health problems such as cooling disease have been pointed out.

  Therefore, it is desirable that the house can coexist with the natural environment by effectively utilizing natural energy without compromising comfort and convenience, and supplementing parts that cannot be supplemented with equipment.

  An object of the present invention is to provide a microclimate design building capable of improving the ventilation and exhaust heat action and effectively reducing resource energy and electric power consumption by effectively using natural energy.

  A microclimate design building that takes in air from the outside and exhausts the air from the upper floor or roof, with multiple openings on the lower floor of the building and positions away from the openings on the lower floor And a wind tunnel provided on the ceiling of the lower floor, and a heat exhaust tower provided on the roof of the building, and an air flow passage is continuously formed by the rail, the wind tunnel, and the heat exhaust tower. In addition, the direction in which the opening is located corresponds to the summer main wind direction in the area where the building is built.

  According to the present invention as described above, by effectively using natural energy, it is possible to improve ventilation and exhaust heat action and to reduce resource energy and power consumption. That is, outside air is taken in from the opening, and the outside air flows into the living rooms of the building from the balustrade. Also, because the bamma, the wind tunnel, and the exhaust heat tower continuously form an air flow passage, the heat trapped in the room passes through the wind tunnel from the bam and passes through the exhaust heat tower by natural convection. Heat is exhausted to the outside. In other words, since the entrance and exit of the wind are provided, the resident can improve the comfort by obtaining a feeling of airflow, can suppress the use of equipment such as cooling as much as possible, and is also good for the internal environment It becomes.

  Preferably, at least one of the plurality of openings is a ground window, and the ground window and the space have an opening / closing function. When formed in this way, the building is excellent in heat insulation and airtightness, and can comfortably spend the winter. In other words, opening the opening (ground window) and the space in summer is effective for ventilation and exhaust heat, and closing the opening (ground window) and the space in winter ensures airtightness and releases heat. It becomes possible to make it a structure without. In addition, since the opening is a ground window installed on the lower side of the wall, even when opening the ground window to take in outside air, it has a structure that takes privacy into consideration without worrying about the external line of sight. ing.

  It is desirable that the direction in which the opening is present corresponds to the summer main wind direction in the area where the building is built. When it does in this way, ventilation and exhaust heat can be performed effectively. That is, the wind varies depending on the climatic characteristics of the region. Therefore, the opening can effectively take wind into the living room from the opening by making it correspond to the main wind direction of the area where the building is built.

  As described above, according to the present invention, natural energy can be effectively used to improve ventilation and exhaust heat action and to reduce resource energy and power consumption.

The positional relationship between the ground window 10 and the space 12 is located on a diagonal line, and the ground window 10 is provided with an open window 13 that can be opened and closed. In addition, the space 12 is provided with a rotary door.

  Therefore, it can be set as the structure where external air is taken in from the ground window 10 and the external air flows into each room of the building from the balustrade 12. In addition, the building is excellent in heat insulation and airtightness, and can be comfortably spent in winter. That is, opening the ground window 10 and the rail 12 in the summer is effective for ventilation and exhaust heat, and closing the ground window 10 and the rail 12 in the winter ensures airtightness and does not release heat. It becomes possible. Furthermore, since the ground window 10 is installed on the lower side of the wall, it has a privacy-friendly structure without worrying about the external line of sight even when the ground window 10 is opened to take in outside air. Yes.

  As shown in FIG. 5, a wind tunnel 14 is provided on the ceiling of the living room 4. The wind tunnel 14 is formed with an opening 14b so that air passes vertically from the first floor to the second floor, and the air is discharged from the heat exhaust tower 15 to the outside. That is, the house T has a continuous air flow in which the outside air taken in from the ground window 10 passes through the balustrade 12, flows into the living room 4 and the like, and is discharged from the exhaust heat tower 15 to the outside via the wind tunnel 14. A road is formed.
