Description

  The present invention relates to a building.

  For example, Patent Document 1 describes a conventional building. In this building, the interior space surrounded by the outer skin (the “outer skin” in the same document) is divided into an interior room (the “room” in the same document) on the center side of the building and a perimeter room (the “double” in the same document). The skin space ") is partitioned into an openable / closable inner skin (" inner skin "in the same document) so that people can come and go.

  In the above-mentioned conventional building, the top skin on the roof of the perimeter room on the top floor can be provided with a translucent solar panel.

JP 2006-291626 A

  However, in the above-mentioned conventional building, the sunlight that is inserted into the perimeter room is blocked by the blinds, and at the same time, the view from the room to the outside is blocked, and the view from the room tends to be impaired. On the other hand, when the blind of the perimeter room is opened, heat is applied to the perimeter room due to the insertion of sunlight, and the energy saving performance is reduced.

  Moreover, in the said conventional building, since a solar panel can be provided only in a rooftop, the restrictions of the electric power generation amount by a solar panel became large. For example, even if a solar panel is attached to the outer wall in order to eliminate this restriction, the opening area is reduced, and a disadvantage that the view from the room to the outdoors is blocked is newly generated. For this reason, it has been difficult to efficiently create energy using sunlight.

  In view of the above circumstances, it has been desired to provide a building that can realize excellent energy saving and high efficiency energy generation while securing a view from the indoor side and securing more installation space for solar panels.

The building of the present invention
An indoor space surrounded by an outer skin is a building partitioned into an interior room on the center side of the building and a perimeter room on the outer periphery side of the building in a state where people can come and go by an openable inner skin,

A solar panel provided on the upper surface of the buttock,
The upper surface of the buttock or the outer skin is provided with an outdoor opening that communicates an outdoor space and a panel back space located on the back side of the solar panel in the inner space of the buttock,
The indoor space is provided with an indoor opening that allows the indoor space and the panel back space to communicate with each other via the internal space and the ceiling pocket of the perimeter room.

According to the present invention, by providing the collar, energy can be created by increasing the installation space of the solar panel using the upper surface of the collar while reducing the thermal load of the perimeter room and the interior room. .
Thus, since the solar panel is provided on the upper surface of the buttock, the outdoor view of the perimeter room is not obstructed by the solar panel, and the solar panel can be installed in a manner that does not impair the view.
And the heat (radiation heat and heat accompanying power generation) of the solar panel is released to the panel back space located directly behind the solar panel in the inner space of the buttock.
In the panel back space from which the heat of the solar panel is released, an upward flow of air is generated by the heat, and this upward flow leads from the indoor opening communicating with the indoor space to the outdoor opening through the internal space including the panel back space. It is possible to generate an air flow. Thereby, natural ventilation of the indoor space (for example, perimeter room in summer etc.) using sunlight can be performed. As a result, air-conditioning costs such as cooling the indoor space can be reduced and energy saving can be improved.
Further, the heat of the solar panel that has escaped to the back space of the panel is supplied to the indoor space through the internal space including the back space of the panel and the indoor opening, thereby heating the indoor space (for example, heating of the interior room in winter) It is possible to do. Thereby, the indoor space using sunlight can be heated. As a result, air-conditioning costs such as heating the indoor space can be reduced, and energy saving can be improved.
Furthermore, since the solar panel can be provided not only on the rooftop of the building but also on the eaves of each floor, the amount of power generated by the solar panel can be sufficiently secured. In addition, the solar panel heat is actively released to other places through the panel back space as described above, so the solar panel is cooled efficiently and the power generation efficiency of the solar panel is good. Can be maintained. Thereby, highly efficient energy creation using sunlight is realizable.

It is preferable that a light duct provided between the daylighting unit and the interior room via the internal space and the ceiling pocket and for guiding sunlight taken from the daylighting unit to the interior room is preferably provided. It is.

  According to this structure, sunlight is taken in from the lighting part provided in the upper surface of the collar part, and the taken-in sunlight is guide | induced to an interior room with an optical duct. Thereby, it becomes possible to perform the illumination by the sunlight in an interior room, and can improve the energy-saving property of an interior room.

In the present invention,
It is preferable that the solar panel, the outdoor opening, and the daylighting unit are provided on the upper surface of the flange in a state in which the solar panel, the outdoor opening, and the daylighting unit are arranged in this order from the outdoor side. .

According to this configuration, since the solar panel is located at a location where it protrudes from the outer skin to the outside, it is easy for the solar panel to hit sunlight, and it is easy to secure the amount of power generated by the solar panel. can do.
Furthermore, when the daylighting unit approaches the interior room side, the duct length of the light duct is shortened, and the light amount loss of sunlight in the light duct can be suppressed.

The intermediate period is between the summer period and the winter period, for example, the spring period, the autumn period, and the like. In the intermediate period, the solar mid-sea altitude is lower and the solar radiation angle is smaller than in the summer.

  In the intermediate period, for example, the outer sash 4 is opened and the inner sash 5 is opened. Thereby, the air in the outdoor space 33 can be directly taken into the inner chamber 2 through the opened outer sash 4 and the opened inner sash 5. Moreover, sunlight can be taken in from the lighting part 19 and can be guide | induced to the inner chamber 2 through the optical duct 20 grade | etc.,.

  Then, the opening / closing mechanism 35 of the indoor opening 21 is opened. Due to the temperature difference between the air in the panel back space 29 and the air in the outer chamber 3 that is warmed by the heat of the solar panel 16, the generation of an upward flow of air in the panel back space 29 is promoted. Thereby, ventilation of the outer chamber 3 can be performed efficiently. Moreover, it becomes possible to escape the heat | fever of the solar panel 16 efficiently by this, and the fall of the power generation efficiency of the solar panel 16 can be suppressed.

[About usage in winter]
FIG. 6 shows an example of winter usage.
In winter, the solar mid-sea altitude is lower and the solar radiation angle is smaller than in the intermediate period.

  In winter, for example, the outer sash 4 is closed and the inner sash 5 is closed. Thereby, the outer chamber 3 becomes a double skin space sandwiched between the outer sash 4 and the inner sash 5. In the winter, sunlight that is not shielded by the buttocks 15 also enters the outer room 3. For this reason, the outer chamber 3 is warmed like a greenhouse. Moreover, sunlight can be taken in from the lighting part 19 and can be guide | induced to the inner chamber 2 through the optical duct 20 grade | etc.,.

  Then, the opening / closing mechanism 35 of the indoor opening 21 is closed. The heat released from the solar panel 16 to the panel back space 29 from the panel back space 29 in the chamber 17 through the heat recovery path P by the heat recovery mechanism (not shown) in the indoor space 1 of the other floor. 2 is sent. Thereby, heating of the inner chamber 2 of the indoor space 1 on another floor can be performed using the heat of the solar panel 16.
