The length of the cantilevered overhangs of the cantilevered roof plates was calculated to prevent midday summer sun from directly entering the building. The overlapping plates act as light shelves that bounce the natural light into the building. This provides occupants with an abundance of diffuse natural light throughout and saves energy as less artificial lighting is required. The saddle shape of the five main roof plates was derived to collect water as well as provide optimum tilt angles for the integrated solar panels. The collected storm runoff water is used to flush the toilets and irrigate the minimal landscaping surrounding the building.
