GSA and Defense Move Energy-Saving Innovations Off the Drawing Board


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:

  • Use open solicitations to identify potential technologies to be tested.
  • Select emerging technologies that have the greatest potential for delivering energy savings and enhanced energy security and reliability.
  • Include careful documentation of baseline data and detailed monitoring and verification of costs and effectiveness.
  • Provide credible, detailed information about product performance that is critical to the technology’s future success in the marketplace.

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.

    Federal Government spending on ‘obsolete technology’ continues to increase. Supporting the twin pillars of improved digital service delivery for citizens on the one hand, and the increasingly optimized and flexible working practices for federal employees on the other, are neither easy nor inexpensive tasks. This whitepaper explores how federal agencies can leverage the value of existing agency technology assets while offering IT leaders the ability to implement the kind of employee productivity, citizen service improvements and security demanded by federal oversight.

    MIT Technology Review: Flash Storage As a Strategic IT Asset For the first time in decades, IT leaders now consider all-flash storage as a strategic IT asset. IT has become a new operating model that enables self-service with high performance, density and resiliency. It also offers the self-service agility of the public cloud combined with the security, performance, and cost-effectiveness of a private cloud. Download this MIT Technology Review paper to learn more about how all-flash storage is transforming the data center.
