Project overview: 

The School of International Service (SIS) at American University created an integrated site and multiuse building that work together to produce a more sustainable environment for the university. The site was previously an impervious parking lot, but now works to recycle and filter all stormwater on the site. This is accomplished by collecting water from the building roof in a cistern for recycling to use in the building toilets. Stormwater detained on the site is reduced and filtered through green roofs, bioretention, and vegetated buffers. The building has also earned a LEED® Gold rating. A variety of outdoor seating opportunities were included to help facilitate interactions between students, faculty, staff, and guests. Other sustainable features include xeriscape planting, edible plants, LED lighting, and no irrigation.
