Hawai'i Public Housing Authority has selected Ameresco Pacific Energy to provide energy services and energy-related capital improvements at its 67 Federal sites throughout the state.

The services and improvements will be designed to reduce energy and water use as well as related costs, the HPHA said in a news release.

Potential savings are conservatively estimated at up to $40-80 million cumulatively over the next 20 years if all recommended energy projects are implemented.

"The potential for energy and cost savings under this comprehensive program is enormous," said David J. Anderson, executive vice president of Ameresco Pacific Energy.

"Hawai'i has one of the larger housing authorities in the country, therefore it is in the state's best interest to explore the benefits of implementing an aggressive energy conservation plan. We applaud the state's efforts and are proud to be a part of the team."

Many housing authorities across the U.S. have implemented similar energy savings contracts, which are supported by the U.S. Department of Housing and Urban Development.
