Description

  The present invention relates to a building provided with a daylighting structure portion that can efficiently perform daylighting and ventilation from an atrium.

  A building is known in which a ventilated portion is provided inside the building so that daylighting and ventilation can be effectively performed (for example, see Patent Document 1). If the atrium space is high enough to reach the ceiling or attic, the atrium will be formed in the living area beyond the moderate height that gives it a spacious and open feeling. It becomes impossible to use effectively, and a useless space is generated in the atrium.

For this reason, for example, the floor on the second floor is raised to form a floor height room, the first floor ceiling directly below this floor height room is raised, and the floor height room is used as the middle third floor. In addition, there is also disclosed a building in which a space directly above the atrium portion can be used effectively by using a room immediately below the middle third floor as a room with an atrium portion (see, for example, Patent Document 2).
