A brief description of when and why the energy consumption baseline was adopted:

Archived energy usage data is available from fiscal year 1999-2000 forward in response to the California State University (CSU) Executive Order 785 (2001) mandated Energy Conservation Goal and reporting requirements.

A brief description of energy use standards and controls employed by the institution:

Per CSU Executive Order 987 (2006), "Purchased energy resources on CSU facilities will not be used to heat above 68 [degrees] F or cool below 78 [degrees] F. Domestic hot water temperatures will not be set above 115 [degrees] F. These limits will not apply in areas where other temperature settings are required by law or by specialized needs of equipment or scientific experimentation."


A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

Exterior lighting for buildings, parking lots, walkways, and streets on both campuses were retrofit in 2013/14 to LED fixtures with automated dimmable and daylight scheduling.

Interior lighting was retrofit from T12 to T8 fluorescent ballasts and lamps was completed in 2007 on San Bernardino campus, and automated occupancy bi-level controls installed in all major stairwells. Beginning in 2010, targeted interior areas are being retrofit to LED as remodeling or replacements are required.


A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

In this warm climate, passive solar heating is not a functional design feature. Shaded or recessed windows and reduced southern exposure is utilized in building designs to help minimize heat load in warm months.


A brief description of co-generation employed by the institution:

Fully operational in Fall 2013, the San Bernardino campus is now home to a 1.4 MW cogeneration fuel cell power plant owned and operated by Southern California Edison. The plant supplies waste heat to the central heating system for the campus.
