The Forrestal Building, which stands as the centerpiece of the Energy Department's headquarters complex, has recently undergone a change that will save the U.S. taxpayers an estimated $600,000 every year.
"Through the installation of the new chiller plant, we're saving money on our air conditioning bills with more efficient equipment while providing much more reliable air conditioning to our critical facilities", said Peter O'Konski, director for the department's Office of Administration. "That's good for our environment, our customers, and our bottom line."
The chiller plant was constructed through an Energy Savings Performance Contract, a public-private partnership that allowed the department to apply industry best practices and use private financing for the project. The financing costs are recovered from energy savings.
The partnership is also ushering in improvements like LED exterior lights, steam trap repairs and a variable air volume system that are expected to save $59.5 million in the long term. For the complete story, see the DOE Energy Blog .
