DFC energy conservation measures environmental assessment
The Denver Federal Center (DFC) is a 570-acre campus open to the public and located along U.S. Route 6 in Lakewood, Colorado, approximately eight miles west of downtown Denver. The DFC is one of the largest contiguous parcels of land in Lakewood that is owned by a single entity. The DFC was acquired in 1941 by the federal government for the purpose of small arms ammunition production. After World War II, the ammunition plant was closed, and the buildings were converted to office, research, and administrative use by a number of federal agencies. The DFC continues to serve numerous federal agencies to this day.
The purpose of the proposed project is to decarbonize and electrify the DFC as much as possible, utilizing clean on-site renewable energy generation and electrification solutions. The proposed project is needed to meet the objectives of GSA’s National Deep Energy Retrofit Program by cutting grid-purchased energy use by approximately 75% and water use by approximately 29% across the DFC. As noted above, the DFC was constructed in the 1940s and relies heavily on energy that is generated from nonrenewable sources. The proposed project would modernize energy infrastructure at the DFC, reduce lifecycle operating costs, and mitigate risk associated with future fossil-fuel price volatility.
GSA will draft an environmental assessment (EA) for the proposed project in compliance with the National Environmental Policy Act. Currently, two action alternatives are being considered in the EA. The first alternative would use a centralized geothermal bore field co-located with a solar photovoltaic (PV) array. The second alternative would use decentralized geothermal bore fields adjacent to each building receiving geothermal heating and cooling. Both alternatives would install the solar PV array in the southeast quadrant of the DFC.
The public scoping period closed on Monday, December 4, 2023.
