By being supported, the eaves 13a can be projected further to the south side than the protruding portion 20 of the second floor portion 20, so that the installation surface of the solar panel 15 is provided on the south side roof surface 13. , It is possible to expand to a wider area.

  Further, this makes it possible to effectively block the sunlight incident on the projecting portion 22 of the second floor portion 20 by the eaves 13a, for example, in the severe summer sunlight, and to the first floor portion 30. Incident sunlight can be effectively shielded by the projecting portion 22 and the eaves 13a of the second floor portion 20, and for example, when the solar radiation in the winter is mild, the second floor portion 20 projects. Sunlight can be taken into the protruding portion 22 and the first floor portion of the second floor portion 20 so as to be hidden under the eaves 13a of the portion 22 and the south side roof surface 13, so it is cooler in summer By creating a warmer indoor environment in winter, it is possible to effectively reduce power consumption due to air conditioning and contribute to addressing environmental problems.

  Furthermore, since the balcony part 23 is provided in the protrusion part 22 and the balcony part 23 is covered by the south side roof surface 13, the depth part of the balcony part 23 and the eaves 13a of the south side roof surface 13 are provided. By deepening, it becomes possible to improve the solar radiation shielding effect especially in summer.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, the main roof provided above the top floor portion does not necessarily have to be a gable roof, but is arranged on the north side, such as a dormitory roof, on the south side with the south side roof surface arranged on the south side across the roof building. Other roof shapes including the north side roof surface may be used. The building may be a three-story or higher building. The building may be other various buildings other than the residential building part.
