Amber worked together with the DC Fire & Emergency Medical Services Department to install up to 35,000 square feet of Aqualok Cool Green panels on 3 DC Engine Companies. The project was funded in part by an Innovative Stormwater and Nutrient Reduction (ISNR) grant to DC F&EMS from the Chesapeake Bay Stewardship Fund administered by the National Fish and Wildlife Foundation (NFWF).
Aqualok panels were installed at Engine Company 12, Engine Company 7 and the Fleet Maintenance Building to monitor stormwater quantity and quality reductions as well as any reductions in energy usage. An initial report on Engine 12 after one year showed electrical consumption down 15% at Engine 12 during cooling degree days in comparison with a comparable station that did not install a green roof. This would equate to a 5% annual reduction in electric consumption.
In addition to the rooftop panels, Amber has installed Aqualok ground-level bioswales. Each 170 gallon bioswale will treat 1" of storm water for 250 s.f. of roof area. Units may also be joined together to treat a impervious area.
