Innovative Water Conserving Design Features
The butterfly roof stands out as the most memorable design element of the building. As stated previously, the dramatic roof shape functions not only to collect rainwater, but to educate– by raising awareness of the preciousness of water as a vital resource.
At the center of the butterfly roof valley, a large “cricket” helps channel water out towards both the east and west ends of the building, where the flow is then captured into large collection funnels, and then directed into the landscaping. The plant life which relies on this water includes the deciduous vines which play an active role in shading the building during the summer cooling season.
