Dr. Fassman-Beck’s Living Laboratory for Stormwater Green Infrastructure (GI) is a research and demonstration site on the Stevens Institute of Technology campus. With 47 individual GI systems, custom-built from the ground up to measure real-world results, the Living Laboratory is dedicated to engineering GI solutions for urban stormwater challenges. The Living Laboratory’s current inventory includes 4 bioretention planters, 38 pilot-scale green roof systems (plus 2 “conventional” pilot-scale roofs), and 3 rain gardens, along with ~100 sensors. Generating quantitative hydrologic and water quality performance data to advance GI design, modeling, and policy is at the heart of the Living Laboratory. Multi-disciplinary efforts engage Software Engineers for Big Data manipulation and Stevens’ Center for Innovation in Engineering Science and Education to engage the next generation of sustainable development professionals via K-12 STEM education initiatives.

Stevens and the Living Laboratory is a Regional Center of Living Architecture Excellence, in partnership with the Green Infrastructure Foundation and Green Roofs for Healthy Cities.
