Solar Arrays How Solar Energy Works on the DFC The Solar Field Arrays send electricity to the inverter, then the transformer and finally the medium voltage grid before being sent to the DFC Substation. The Solar Roofs on the DFC buildings as well as the Solar Carports also send electricity to the inverter, then the transformer and finally the medium voltage grid before being sent to the DFC Substation. The electricity at the DFC Substation is then sent to the Bi-Directional Meter and finally the utility grid.
Sustainability at the DFC The General Services Administration is leading by example when it comes to sustainability. These projects are some of the many environmentally responsible products and technologies being implemented across the Denver Federal Center (DFC) campus.
Pervious Concrete Parking Lot Reduces storm water runoff. Recharges groundwater aquifers Reduces snow and ice in vehicle parking areas By capturing storm water and allowing it to seep into the ground, pervious concrete is instrumental in recharging Groundwater, reducing storm water runoff, and meeting U.S. Environmental Protection Agency (EPA) storm water regulations.
Carports with Solar Arrays Reduces the urban heat island effect so buildings don't use as much fuel for air conditioning. Keeps automobiles cooler so they don't use as much fuel for air conditioning Generates energy from the sun.
