PURPOSE:To save cooling and heating energy and effectively utilize the ground surface by constructing an underground conical structure, providing a water reservoir on the bottom part thereof, and storing rainwater between a circumferential wall part and a story part to utilize it. CONSTITUTION:The ground surface is conically excavated down to form the circumferential wall 12 of an underground structure 10. Story structures 16 consisting of radially extending beams 18 and story plates 20 supported by the beams 18 are constructed in the inner part of the circumferential wall 12, and a reservoir 25 is constructed on the bottom part. Spaces having a prescribed interval are provided between the circumferential wall 12 and the outer edges of the story plates 20 to utilize the natural lighting to each layer and the collection of rainwater to the reservoir 25. Cooling and heating energy is saved by the circulation of the rainwater stored in the reservoir 25 and the utilization of the ground heat, and the ground surface can be also effectively utilized. |
