DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1
Next, the building 100 of Embodiment 1 of this invention is demonstrated based on drawing.
[0031]
1 and 2 are views showing a building 100 according to Embodiment 1 of the present invention.
[0032]
First, the structure will be described. The building 100 according to the first embodiment of the present invention includes a foundation 10, a main body 20 assembled on the base 10, a roof 30 covering the main body 20, and a roof 30. The solar power generation panels 40 and 40a are configured to receive the power generated by the solar power generation panels 40 and 40a.
[0033]
As for the frame main body 20, the south side lower shed part and the north side two-story part are united, for example. In the example shown in FIG. 2, the south side lower floor is the living room 21, the north side two-story part has a kitchen 22 in contact with the living room 21 on the first floor, and a washroom 23 on the north side of the kitchen 22. Has a master bedroom 24.
[0034]
The living room 21 has, for example, a ceiling 21b that is close to the roof and has the same gradient so as to have an atrium space 21a with a ceiling height for a later-described downed roof. The living room 21 has a sweep-out window 21c facing south, a window 21d between the main bedroom 24 and a skylight 21e.
[0035]
The roof 30 is composed of upper floor roofs 31, 31a, 31b of a two-story part and a lower floor roof 32 of the lower part. The upper floor roof 31 is provided on both sides with the ridge 33 as a boundary, and the upper floor roof on the south side. 31 and the lower-floor roof 32 constitute a roof 34 that is continuously lowered from the ridge 33 to the eaves 35 on the same surface.
[0036]
Adjacent to the upper floor roof 31 of this thatched roof 34, another upper floor roof 31a having the same surface or a step is provided, and the upper floor roof 31b is provided on the opposite side through the ridge 33 of the upper floor roof 31. Is provided. A balcony 25 that is open to the outdoors is provided adjacent to the other upper-floor roof 31a and the lower-floor roof 32 of the thatched roof 34.
[0037]
In order to effectively use the solar power generation, the solar power generation panel 40 is laid on the roof 30. This solar power generation panel 40 is standardized, for example, presents a rectangular plate with a length of 1577 mm and a width of 783 mm, or a rectangular plate with a half length, and solar cells (not shown) are disposed therein, The power generation amount per one photovoltaic power generation panel 40 is, for example, about 0.171 kW.
[0038]
The thatched roof 34 covers almost the entire area from the ridge 33 to the eaves 35 as a photovoltaic power generation panel, for example, a photovoltaic panel 40a having a full length that is half the normal length and a photovoltaic power generation having a normal full length. Four panels 40 are laid in a column, and this is laid in a row in six rows.
[0039]
The other upper-floor roof 31a and upper-floor roof 31b are also arranged in consideration of an arrangement in which as many solar power generation panels 40 as possible can be laid. A space 36 is formed around the roof 30 on which the photovoltaic power generation panels 40 are laid. The vacant space 36 is generally generated in a larger area when the upper-floor roofs 31, 31a, 31b and the lower-floor roof 32 are separated from each other or are not the same surface but are independent.
[0040]
Therefore, it is possible to reduce the useless empty space 36 as much as possible by using the thatched roof 34 or by making the upper-floor roof 31 and the other upper-floor roof 31a adjacent to each other on the same plane. That is, the photovoltaic power generation panel 40 can be arranged continuously at the position of the empty space 36 that would be possible if it was singly, and can be laid effectively.
[0041]
Moreover, if it is not a thatched roof but a large upper floor roof having the same area, the floor area on the second floor increases, the total floor area increases, and the entire roof becomes higher. In contrast, in this embodiment, the floor area is not increased more than necessary, and the height of the roof is suppressed, so that workability and safety during construction and maintenance are good.
[0042]
In the first embodiment, one of the many photovoltaic power generation panels 40 is made of a window glass with good translucency except for the solar battery, and here is a skylight 21e that can be opened and closed. Below the lower-floor roof 32, the building 100 is provided with an atrium space 21a and a skylight 21e provided on the lower-floor roof 32 for daylighting the atrium space 21a. The lighting and ventilation to the atrium space 21a and the living room 21 are made from the skylight 21e, the discharge window 21c, and the like, and the main bedroom 24 is similarly made through the window 21d.
[0043]
According to this configuration, a sufficient amount of power generation is ensured without increasing the floor area, and a space with a ceiling height is formed under the lower floor roof 32, so that brightness as well as a feeling of opening can be enjoyed.
[0044]
Further, another upper-floor roof 31a is provided adjacent to the upper-floor roof 31 of thatched roof 34, and is opened to the outdoors adjacent to the other upper-floor roof 31a and lower-floor roof 32 of thatched roof 34. The balcony 25 is provided, and the solar panel 40 is also laid on the other upper-floor roof 31a. Therefore, the balcony 25 can be secured while increasing the amount of power generation. Since it is easy to climb from 25 to the roof 30, workability and safety during construction and maintenance are further improved.
[0045]
Second Embodiment of the Invention
Next, the building 200 according to the second embodiment of the present invention will be described.
[0046]
3 to 7 are diagrams showing a building 200 according to the second embodiment of the present invention. Note that portions that are the same as or equivalent to those in the first embodiment will be described with the same reference numerals.
[0047]
First, the structure will be described. The building 200 according to the second embodiment of the present invention is mainly composed of a foundation 10 and a frame main body 120 assembled on the foundation 10. Among these, the main body 120 includes a first-floor portion 130 configured by combining first-floor room units 131 and 132 as a plurality of building units, two-floor room units 141 and 142 and a balcony unit as a plurality of building units. 143 and the like, and a roof unit 151, 152, etc. that constitute a stepped roof 150 that covers the upper part of the second floor 140 is mainly configured.
[0048]
Here, the two-story room units other than the south-side two-story room unit 142 have a horizontal upper surface, whereas the south-side two-story room unit 142 has an upper surface inclined along the gradient of the first roof 160. Here, a roof panel 153 constituting the eaves side portion of the first roof 160 is provided continuously with the roof unit 152.
[0049]
That is, the upper part of the room inside the second-floor room unit is partitioned by the eaves side portion of the roof 160 to be equal to or less than the standard height and as an inclined surface.
[0050]
A solar power generation panel 40 is also laid on the upper surface of the roof panel 153.
[0051]
Of these, the stepped roof 150 is mainly composed of a first roof 160 having the same gradient angle and a south flow direction, and a second roof 170 having a north flow direction. The upper end edge 160a of one roof 160 is positioned directly above the upper end edge of the second roof.
[0052]
That is, the first roof 160 extends upward from the intersection (S in FIG. 7) with the extension line V of the second roof 170.
[0053]
And, from the ridge 160b of the first roof 160 to the eaves 160c, except for the upper part of the balcony unit 143, there are a total of 36 photovoltaic panels 40... It is laid.
[0054]
The total output of these photovoltaic power generation panels 40 is about 6.16 kw, and has an output that can almost cover the utility cost of a standard family of four with only photovoltaic power generation.
[0055]
Then, as shown in FIG. 7, the extension line V from the upper edge 170 a of the second roof 170 is closer to the upper edge 160 a of the first roof 160 than the position S where the first roof 160 intersects. Further, the photovoltaic power generation panel 40 is extended and laid.
[0056]
Furthermore, in the second embodiment, a roof vertical wall surface 180 is formed that hangs down from the upper end edge 160a of the first roof 160 and reaches the upper end edge 170a of the second roof 170. And the opening part 181 for ventilation is formed in the roof part vertical wall surface 180 of this Embodiment 2, and the exhaust-heat ventilation fan or the ventilation window 182 is provided.
[0057]
In the second embodiment, a balcony 190 including the balcony unit 143 is provided in the vicinity of the lower end 160 c of the first roof 160.
[0058]
Next, the operation of the building 200 of the second embodiment will be described.
[0059]
In the second embodiment, the photovoltaic power generation panels 40 are laid over almost the entire area of the uneven roof 150 of the building 200 from the ridge 160b to the eaves 160c of the first roof 160.
[0060]
Since the upper edge 160a of the first roof 160 is positioned higher than the upper edge 170a of the second roof 170, the area of the first roof 160 increases, and the photovoltaic power generation panel 40 is installed. The area to be generated can be increased, and sufficient power generation can be obtained.
[0061]
For example, for comparison, in the first embodiment, the photovoltaic power generation panel 40a laid on the most ridge side has a length in the flow direction that is approximately half that of the standard photovoltaic power generation panel 40, and the power generation amount is also compared. In the second embodiment, the photovoltaic power generation panels 40... Laid most on the ridge side can also be used with a standard length in the flow direction, and the amount of power generation can be increased.
[0062]
Here, a single-flow roof that consists only of a south-facing roof further increases the south-facing roof area, but the top edge of the roof becomes too high, and it is easy to conflict with laws and regulations, and the appearance is also monotonous. End up.
[0063]
Furthermore, without increasing the floor area of the building 200, the extension line V from the upper edge 170 a of the second roof 170 is higher than the position S where the first roof 160 intersects the upper edge of the first roof 160. The area where the photovoltaic power generation panel 40 is extended and installed can be increased to the edge 160a side.
[0064]
Moreover, although the balcony unit 143 is provided in the vicinity of the lower end of the first roof 160 to secure the balcony 190 from which sufficient lighting can be obtained, the number of the photovoltaic power generation panels 40 in the vicinity of the eaves is reduced by four. Nevertheless, since the area where the photovoltaic power generation panels 40 are installed is increased in the first roof 160 of the uneven roof 150, a sufficient power generation amount can be secured.
[0065]
Further, in the building 200 according to the second embodiment, the second-floor room unit 142 on the south side has an upper surface that is inclined along the gradient of the first roof 160. The roof panel unit 153 constituting the eaves side portion of the roof 160 is installed, and the photovoltaic power generation panel 40 is also laid on the upper surface of the roof panel 153.
[0066]
The upper part of the room inside the second-floor room unit 142 is sectioned as an inclined surface below the standard height.
[0067]
For this reason, it is possible to increase the area of the roof, that is, the installable area of the photovoltaic power generation panels 40, while suppressing the height of the roof.
[0068]
Furthermore, in this Embodiment 2, the opening part 181 for ventilation is formed in the said roof part vertical wall surface 180, and the exhaust-heat ventilation fan or the ventilation window 182 is provided.
[0069]
For this reason, it is possible to further improve the cooling and heating efficiency with good ventilation. Therefore, even when power tends to be insufficient during cooling and heating, unnecessary cooling and heating can be reduced by ventilation, and electric power can be sufficiently supplied without increasing the floor area of the building.
[0070]
Other configurations and operational effects are the same as or equivalent to those of the first embodiment, and thus description thereof is omitted.

  More, ChangeThe air-conditioning efficiency can be further improved with good tempering. Therefore, even when power tends to be insufficient during cooling and heating, the power can be sufficiently supplied without increasing the floor area of the building.
[0104]
  Also,in frontSince the upper part of the storage room is defined as an inclined surface below the standard height, the area of the roof, that is, the area where the photovoltaic power generation panel can be installed can be increased while suppressing the height of the roof.
[0105]
  And,in frontThe second roof is flush with the first roof, and the eaves of the first roof and the eaves of the second roof are located on the same straight line. Without increasing the area, increase the area of the roof, that is, the area where the photovoltaic power generation panel can be installed
Can do.
[0106]
Further, since the second roof is flush with the first roof, no step is generated in the roof portion. For this reason, a shade part does not arise by a level | step difference, but can improve the power generation efficiency of a photovoltaic power generation panel.
[0107]
  More,in frontSince the eaves of the second roof can be provided above the balcony provided on the outdoor side of the second outer wall, the area of the roof, that is, the installation of the photovoltaic power generation panel can be further increased without increasing the floor area. A practically beneficial effect that the possible area can be increased is exhibited.
