A brief description of when and why the energy consumption baseline was adopted:
The baseline year 2013/14 was adopted to fulfill reporting needs for CSU Sustainability reporting needs and is a year with the most complete data to measure against.
Source-site ratio for imported electricity:
Total energy consumption per unit of floor area:
Site energy | Source energy | |
Performance year | 0.05 MMBtu per square foot | 0.09 MMBtu per square foot |
Baseline year | 0.06 MMBtu per square foot | 0.12 MMBtu per square foot |
Percentage reduction in total source energy consumption per unit of floor area from baseline:

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
The Energy, Utilities and Sustainability team works to educate the campus population on energy efficiency in a variety of ways.
Students:
- Engage students during SLO days summer orientation about energy efficient and green living in the dorms.
-Annual dorm energy competitions provide education and awareness around managing temperatures, taking short showers and turning off lights.
Staff/ Faculty:
- Dedicated module as part of new employee orientation to teach basic conservation awareness and whom to contact for issues.
A brief description of energy use standards and controls employed by the institution:
Cal Poly's High Performance Building Policy sets standards including a requirement to exceed Title 24-2019 by 30%, and to exceed the current version of Title 24 by 10%. Cal Poly also requires all new buildings to be built to LEED Gold standards.
CSU Executive Order 987 governs how campuses utilize utility funding. Cal Poly may not utilize utility funds to cool spaces below 78 degrees or heat them above 68.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
In 2021, Cal Poly completed a retrofit of all exterior lighting, including street lights with LEDs. All new construction is being specified with LED lighting. In 2023, the Kennedy Library will be retrofitted to LED lighting, which as the largest building on campus, will provide energy and demand savings.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Cal Poly does not have any geothermal systems, largely due to bedrock sub-surface. Cal Poly has a robust tree canopy, with many trees intentionally planted to reduce summer heat gain.
A brief description of co-generation employed by the institution:
Cal Poly has 1 co-generation plant on campus, a 250 kW V-12 reciprocal engine in the Poly Canyon Housing complex. This plant generates electricity and provides roughly half the heating needs of the entire complex, including an adjacent swimming pool.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
Cal Poly and CSU procurement policies mandate that ENERGY STAR certified appliances.
Cal Poly is in the middle of scoping what is being called the "DEEP energy project" to retrofit all older buildings with energy efficient lighting, DDC controls, and new air handlers/ coils. With a tentative scope of upwards of $200 million dollars, this should significantly improve the EUI of campus.
