Two Technologies Proven Effective in GSA Test Beds

Currently, plug loads account for approximately 25% of electricity use in office buildings and lighting for 39%. GSA found that advanced power strips with schedule-based power controls reduced workstation plug loads by an average of 26% in the eight buildings in which they were tested. The lighting study evaluated workstation-specific systems with dimmable ballasts and occupancy sensors, which across five buildings reduced lighting energy use by 27%–63%.

GSA has announced a number of upcoming tests in the Green Proving Ground program, including glazing retrofit coatings and solar thermal collectors. For more information, see www.gsa.gov/gpg.
