A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

The Office of Sustainability, Center for Sustainability, Parking & Transportation Services, and Associated Students host campus events related to energy efficiency during Sustainability Month and Earth Week. Recent events include: Titan Clean Air Day, The Future of Energy, Planting Seeds of Resilience, and the Green Career Panel. Throughout the year, campus departments share energy saving tips on social media platforms via Instagram, Facebook, and Twitter.

The Office of Sustainability offers sustainability tours upon request which includes energy efficient features including the solar canopies, green buildings, solar powered ConnecTables, LED lighting, electric vehicle charging stations, campus electric fleet, and the Trigeneration Plant.

In Fall 2021, The Office of Sustainability worked with students from Chemistry 492 on a project related to researching renewable energy for the campus such as green hydrogen.

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

At the Central Plant, an Allen Bradley Balance of Plant (BOP) energy management system monitors and controls the production side of the operation. Plant operators reference an energy dashboard to monitor the output of PV, tri-generation, and So Cal Edison electricity resources to ensure the program is maximizing the lower cost PV and tri-gen components while maintaining a small (200kW) Edison import to obtain the best value for the university. Hot and chilled thermal energy storage tanks are charged via absorption chillers (which operate off the tri-gen waste heat) or a variable speed electric chiller which is operated when we have excess PV energy or during overnight hours when Edison electric rates are at their lowest.

Campus HVAC and lighting is controlled via an Andover BMS program. HVAC equipment and lighting is scheduled on/off. Office and classroom HVAC is controlled between 68F (heating set point) and 76F (cooling set point). Economizer controls are incorporated where applicable (office and non-laboratory class rooms). In 2017, the library HVAC system was upgraded and now uses a trim and respond control sequence to maximize HVAC energy efficiency. The trim and response control sequence is now standard for all new construction and renovation.

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

The campus has exterior LEDs along with parking lots, parking structures, pedestrian areas, and building exteriors. In 2016, the campus completed a campus wide retrofit, converting 25 watt T8s to LEDs. Savings from this project was 4 Million kWh. Over 90% of the campus now has LED lighting. Most recently, the campus upgraded the Gymnasium lighting to LED to meet NCAA standards.

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

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

CSUF has a 4.6 MW natural gas powered turbine generator feeding waste heat to (2) absorption machines. The machines make both heating hot water and chilled water that is stored in the campus' thermal energy storage tanks for use during peak periods.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:

In 2019, the campus replaced ten rooftop packaged AC units with air-source heat pumps with Seasonal Energy Efficiency Ratio (SEER) of 16 and above. Two new DC fast charging electric vehicle stations were installed behind the College of Business and Economics to replace two outdated EV chargers. In 2020, campus added 500 kW PV system on top of the Eastside Parking Structure 2.

Additional documentation to support the submission:

Based on the GHG report in OP-1, we used a CO2 factor of 3.56E-04 tons/kWh for Purchased Electricity. This factor was provided to us by Southern California Edison, our electricity provider.

This credit includes information for the Main Fullerton Campus. Locations within the institutional boundary not included in this credit are the Grand Central Arts Center in Santa Ana, Fullerton Arboretum, the Desert Studies Center in Zyzzyx, and the President's house. The reason for this is these locations are run via separate operations.
