This is the sixth in a series of sustainability case studies developed by the Center for Climate and Energy Solutions.
As two of the largest property owners and managers in the country, the Defense Department and the General Services Administrative have a compelling interest in reducing energy use in buildings. The Pentagon’s annual tab to power the roughly 300,000 buildings in its portfolio runs nearly $4 billion.
But what if some of the best new energy-saving technologies never get off the drawing board? By using federal facilities to test real-world performance, Defense and GSA are helping to bridge the "technology valley of death" that prevents many innovations from moving to commercialization. In return, they expect to cut costs as well as improve reliability at their facilities.
Defense’s Environmental Security Technology Certification Program’s installation energy test bed initiative has supported more than 70 projects since it began in 2009. GSA’s Green Proving Ground, which started a year later, has initiated testing of more than 20 energy-saving technologies.
Following a similar format, both programs:
The programs differ mainly in the stage of development of the technologies they test. The Pentagon’s initiative focuses on technologies that are often at a pre-commercial stage. GSA’s program focuses on underutilized existing technologies and new technologies that are just entering commercial markets.
The programs cover a wide range of technologies, including smart microgrids, energy storage, and advanced metering, sensors and controls.
For example, at Fort Detrick, Md., the Army will test a hybrid electricity generation system that integrates DC-connected bulk energy storage with solar photovoltaic power sources. The objective is to enhance installation energy security, reduce dependence on grid-supplied power, and reduce energy costs.
GSA’s Green Proving Ground is testing a plug load technology at six federal sites that tracks the amount of electricity consumed by workspace electronics, including computers, task lights and printers. The system shows building occupants how their behavior contributes to overall building energy use. Plug loads are estimated to account for 15 to 35 percent of total building energy consumption.
By helping to move new energy-saving technologies into the marketplace, these programs could have a substantial payoff for the government and society at large.
