Between 2010 and 2012 the Energize program, made possible by a federal grant, the Energy Efficiency and Conservation Block Grant (EECBG) established as part of the American Recovery and Reinvestment Act of 2009 (ARRA) had several areas of focus. The Office of Sustainability managed this grant and a State Energy Program grant for public building retrofits in partnership with several other County divisions.
Initiatives include partnering with Energy Trust of Oregon to provide close to $1 million cash incentives for energy efficiency retrofits of homes and businesses. We collaborated with Clean Energy Works Oregon to offer low interest loans and rebates for weatherization projects in Clackamas County. Public buildings had energy assessments and energy efficiency upgrades have been completed on several of them (see below). Active solar electric systems are in place on the Development Services and Brooks Buildings.

In recent years the County has reduced energy use per employee in its buildings and continued its commitment to energy efficient facilities. As funds are available, Facilities Management upgrades buildings with more efficient equipment for lighting, heating and cooling or in sealing the buildings. Three of the largest county facilities were constructed or renovated substantially with energy savings in mind, including one LEED Gold certified building (the Development Services Building), one LEED Silver certified building (the Public Services Building) and the recently-renovated Brooks Building slated to meet LEED. The Public Services and Development Services Buildings also received Energy Star status in 2012.
Several of the county’s more than 50 buildings have benefited from energy-efficiency upgrades. In the last three years at least 19 projects in 15 buildings have helped to reduce energy use. The Facilities Management division used these grants in 2010 - 2012 to upgrade several buildings with efficient lighting, new insulation, boilers, and windows.
The following table summarizes improvements made in 9 buildings in 2011 with grant funding from the State Energy Program. The total cost of the projects was approximately $430,000, and estimated annual savings from these projects is approximately $75,000. The estimated return on investment is less than 6 years for buildings that are likely to remain in service for decades more. In the near term, these projects allowed the county to hire local contractors and keep staff electricians.
