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 2019-20 academic year include:

-Central Plant Open House Tours during 2019's 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.
-Before winter break, sent out a campus-wide e-mail to encourage holiday shut down of un-needed appliances and lights.
-During March Race to Reduce Month, conducted a Take the Stairs Campaign to draw attention to taking the stairs (instead of the elevator) as an energy conservation measure.
-The Office of Sustainability hosts annual energy competitions for Housing residents to encourage them to reduce their electricity (Phase I residents) and natural gas (Phase II residents) use as they are sub-metered for those utilities.


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 is also participating in a California Energy Commission case-study which is providing funding that is currently retrofitting two major campus buildings (Welch Hall and the Loker Student Union) 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.

Additional documentation to support the submission:
---

CSUDH replaced natural gas absorption chillers with electric chillers and one large natural gas boiler with eight small condensing staged boilers in 2019 and was able to achieve a 57% reduction in natural gas. This innovative project earned a statewide best practice award in Energy Demand at the CA Higher Ed Sustainability Conference.
