Background

Santee Education Complex opened in July 2005 as the first new four-year high school for the Los Angeles Unified School District (LAUSD) in over 35 years. The 338,000-square-foot educational complex serves over 1,940 students and 145 staff, and operates as one of the highest energy-consuming facilities compared to the district’s average. In 2014, the Energy Use Index (EUI) for Santee Education Complex was around 130 kBtu/sq. ft.

More

Santee Education Complex is a high school facility located in the Central Los Angeles area. The complex includes classrooms, a library, a gymnasium, offices, and an auditorium building. The campus also has an extensive central open area with athletic fields and a competition-size pool.

LAUSD is the second-largest school district in the United States, with over 1,200 K-12 schools and centers within 720 square miles, serving approximately 640,000 students.

Solutions

In order to reach LAUSD’s 20 percent energy consumption reduction goal by 2024, targeted savings measures that were identified by a recently completed investment grade audit at the facility will be implemented through the Proposition 39* program. The efficiency opportunities identified include interior and exterior lighting upgrades, occupancy sensor installation, an energy management system upgrade, retro-commissioning the set points and operating schedule for the domestic hot water pump, efficient domestic water heater and boiler upgrades, and variable frequency drive (VFD) installation on water pumps. By June 2017, LAUSD anticipates savings of 33 kBtu/sq. ft., which equals a 25 percent EUI reduction.


1Proposition 39 is a state program providing funding to local educational agencies for improving energy efficiency and creating clean energy jobs.
