Documentation to support the performance year energy consumption figures reported above:
A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Website, interaction with campus, Sustainability Coordinator, articles, promoting energy conservation
A brief description of energy use standards and controls employed by the institution:
Night setbacks, equipment scheduling, occupancy sensors, energy recovery, LED lighting, demand controlled ventilation, variable frequency drives, envelope commissioning, LEED Construction
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
The standard across campus is LED lighting. Therefore all new lighting will be LED and in some cases existing lighting is being retrofitted to LED.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
We have a solar wall to preheat outside air at the Stanley J Marshall Practice Courts, solar panels for electricity at four locations, ground source heat pumps at McCrory Gardens Visitor Center
A brief description of co-generation employed by the institution:
SDSU does not employ co-generation methods
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
SDSU only allows energy star equipment when available; all new construction follows LEED standards; remodels include high efficiency equipment

Data source(s) and notes about the submission:
Baseline year data utilizes a 3-year average (FY12, FY13, & FY14).
Performance year data utilizes a 3-year average (FY20, FY21, & FY22). A three year average was also used for the building space statistics. While the healthcare and energy intensive space floor areas stayed the same, the lab floor area changed over the three years which is why this number and the gross floor area are different from PRE 4.
