Mitigation
Reduce Operational Energy
Reduce the energy demand of irrigation systems
Options
…by using building water (like air conditioning condensate).
…by capturing stormwater or recycling on-site water for later use.
…by choosing a gravity-fed drip system rather than a pump-powered system.
Case Study
Reduction of water inputs is key to ration a scarce resource, but creative reuse also reduces the energy demand inherent in water delivery. At Orange Mall, at the center of the Arizona State University campus, Colwell Shelor was able to harness air conditioning condensate—a waste product—as a hyper local irrigation source. The student pavilion generates about 1,000 gallons of water between the peak use months of June-September and is delivered via sculptural brass pipes from the roof area.
