The Iowa Energy Center in Ames has won a competitive $500,000 award from the U.S. Department of Defense that will be used to demonstrate energy-efficient strategies at five Iowa Army National Guard facilities. The award, the first Defense Department funding to be received by the Iowa Energy Center, was one of just 10 awards made nationally from 21 proposals that were selected for full evaluation. The center will partner with the Iowa Army National Guard and Taylor Engineering LLC to demonstrate a ventilation system control strategy developed at the Iowa Energy Center's Energy Resource Station in Ankeny. The project will validate whether the technology could be used in Defense Department facilities nationwide, which would save an estimated $49.4 million in energy costs annually.
