Amber is working 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 had been 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 have already been installed at Engine Company 12, Engine Company 7 and the Fleet Maintenance Building. We are monitoring stormwater quantity and quality reductions as well as 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 equates to a 5% annual reduction in electric consumption.
In addition to the rooftop panels, we have installed Aqualok ground-level bioswales. Each 170 gallon bioswale will treat 1" of storm water for 300 s.f. of roof area. Units can be joined together to treat a impervious area.
