A 165,000 gallon storage tank, created by repurposing an old firearm target range in the basement, allows rainwater to be stored and re-used for toilet flushing, irrigation, and mechanical cooling tower makeup water. The tank also supports another project goal: mitigating the negative effects of urban runoff. In addition, the water collecting “canopy” supports a 180-kW solar array that provides 4% of the building‘s total energy.
