Ameresco, an energy efficiency and renewable energy company, has secured an energy performance contract (EPC) worth $30m to deliver energy savings for the San Francisco Housing Authority (SFHA) over a period of 20 years.

Under this contract, Ameresco will implement energy saving measures like new lighting upgrades, plumbing fixtures, boilers, water heaters, furnaces, decentralized heating fixtures, cogeneration, improved energy management systems and building ventilation, and new windows at some sites.

The energy and water conservation project, which will reach 37 developments and over 5,000 units throughout SFHA, is expected to deliver annual savings of approximately $3.5m in energy costs and save the authority over $60m during the 20-year contract term.

Construction on the energy saving project funded through the American Recovery and Reinvestment Act is anticipated to begin in January, 2011, and will take two years to complete, thereby improving the quality of the facilities, and saving SFHA a considerable amount of money with no up-front costs.
