Water management and rainwater harvesting.

Introduction of a system that retains rainwater on the building site and reduces the outflow of rainwater as much as possible!

The "rainwater retention" indicated by the Japan Architectural Institute's environmental standards is a significant point because it emphasizes the necessity of efforts for flood control and disaster prevention. "Flood control rainwater retention" is a system that retains rainwater on the building site and reduces the amount of rainwater that flows out as much as possible. Of the 120m2 rooftop, 20m2 does not enter the underground tank but flows through a small above-ground tank to the infiltration pipe. Gravel is laid around the building to promote as much infiltration and evaporation as possible.
