Salem Keiser Audits  – Salem Keiser School District – Salem, Oregon

 

Energy Analysis / SB 1149 School Energy Audits

 

Solarc has conducted numerous energy audits on individual schools and systems within the Salem Keiser school district.  Auditing efforts have involved three phases of work.  These audits were done for the Senate Bill 1149 (SB1149) program administered by the Oregon Department of Energy (ODOE). The SB1149 program collects a portion of the 3% public purpose charge from Portland General Electric (PGE) and PacifiCorp customers to help schools implement energy efficiency upgrades.

 

In the initial phase, Solarc teamed up with the Salem Keiser School District and the Lane Community College Energy Management Program to perform audits on (7) Elementary and Middle Schools in Salem, Oregon.  Solarc employees were teamed with student interns from the Energy Management Program to perform these audits.  The goal of these audits was not only to provide Salem Keizer School District with quality energy analysis to acquire SB1149 funding for energy projects but also to help teach the future energy professionals with real world experience.

 

In follow-up phases of work, Solarc worked directly with the district to conduct audits on individual HVAC units at Sprague High School, and conduct target audits for energy efficiency elements within bond-funded improvement projects at Candalaria Elementary School, Englewood Elementary School, Hoover Elementary School, Kennedy Elementary School, Stephens Middle School, Waldo Middle School, and McNary High School.
