Part 2. Reduction in source energy use per unit of floor area
Baseline year energy consumption
STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.
| kWh | MMBtu | |
| Imported electricity | 16,961,920 Kilowatt-hours | 57,874.07 MMBtu |
| Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) | 0 Kilowatt-hours | 0 MMBtu |
Stationary fuels and thermal energy, baseline year (report MMBtu):

| Stationary fuels used on-site to generate electricity and/or thermal energy | 98,760.70 MMBtu |
| Imported steam, hot water, and/or chilled water | 0 MMBtu |

A brief description of when and why the energy consumption baseline was adopted:
This baseline is when AASHE STARS reporting began (also before adoption of the Clean Energy Optimization Pilot program with Southern California Edison/most aggressive greenhouse gas reduction efforts began).

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Energy efficiency behaviors are regularly included in sustainability outreach campaigns and communications. A few specific examples from the 2022 calendar year include:
-Central Plant Open House Tours during October Sustainability Month to help campus users gain a better appreciation of campus energy use as well as regular class tours of the Central Plant tunnels upon request by faculty.
-In fall 2022, sent out a campus-wide "Shut the Door" reminder to encourage users to keep doors closed to preserve HVAC set temperature.

A brief description of energy use standards and controls employed by the institution:
LED lighting with Enlighted occupancy sensors that allow occupancy/vacancy sensing and integrated controls are the campus standard for lighting retrofits and installation.
Central Plant also has automated building controls for HVAC delivery, Pelican thermostats, and other technology to ensure ongoing monitoring and commissioning.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Enlighted with LED lighting technologies are the campus-wide standard and are installed in all retrofitted classrooms and new construction.
The campus also participated in a California Energy Commission case-study which provided funding to completely retrofit two major campus buildings (Welch Hall and the LaCorte Hall building) with all LED lighting.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
CSUDH replaced natural gas absorption chillers with electric chillers and one large natural gas boiler with eight small condensing staged boilers in May 2019. While the energy savings were significant (57% reduction in natural gas), there was also a significant cooling tower water savings from the reduced thermal load resulting in 2.8 million gallons per year in water savings.
CSUDH is one of the participants in the Clean Energy Optimization Pilot, which provides funding for all behind-the-meter efforts to reduce energy consumption/greenhouse gas.
