Los Angeles Unified School District's Helen Bernstein High School

BACKGROUND

The Helen Bernstein High School is a high performance-designed facility, incorporating sustainable and energy-efficient design and construction standards into its site, water, energy, materials, indoor environmental quality, and operations. The Los Angeles Unified School District (LAUSD) selected the facility to undergo an energy efficiency upgrade that is expected to result in a source energy savings of 28 percent and a cost savings of $137,000 annually.

More

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

In 2003, LAUSD’s Board of Education passed a resolution entitled “Sustainability and the Design and Construction of High Performance Schools” directing that the design of all new schools and modernization projects incorporate and meet green building criteria from the Collaborative for High Performance Schools (CHPS).

Opening in 2008, Bernstein High School is one of over 120 LAUSD schools certified as part of CHPS. The facility serves over 700 students and staff across 339,600 square feet and includes classrooms, library, gymnasium, office, and auditorium building. The campus also provides an extensive open area with athletic fields and swimming pool facilities.
