Solar Panels Shine Bright Light on Energy Efficiency at CMS Facility
GSA recently completed an energy savings project at the Centers for Medicare and Medicaid (CMS) in Woodlawn, MD. The project included installation of new high efficiency boilers and chillers, replacement of the existing lighting with new high performance lighting, full roof restoration including an ENERGY STAR cool roof coating, installation of 875 kilowatt (kW) of roof mounted solar panels, and installation of two covered walkways that include another 240 kW of solar electricity. The overall intent is to reduce energy consumption and provide the facility with clean, renewable energy.
The renovations have greatly benefited both GSA and CMS, through reduced energy consumption, increased heating and cooling reliability, and more comfortable and efficient lighting throughout the facility. The facility’s solar photovoltaic (PV) arrays are among GSA’s top five largest PV array installations in the country. These sustainable upgrades help instill a sense of pride in the building tenants as a significant portion of the energy that they use comes from renewable energy.
PV canopies were creatively designed and constructed in the parking lot to both provide a structure for the solar panels, as well as weather protection for tenants walking from the parking lot to the building. The PV canopy structure also served as a location to install battery charging stations for electric vehicles. This new walkway is constructed using pavers composed of 96% recycled tires providing a comfortable and environmentally friendly walking surface.
In addition to the solar energy produced and used at the CMS facility, the PV system has been registered with the state of Maryland and is producing excess energy in the form of solar renewable energy credits. GSA sells these credits, currently worth $150,000 to $200,000 per year, and receives revenue from the utility company.
GSA continues to pursue similar projects that will produce cost and energy savings for federal agencies and American taxpayers.
