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

The CSU community is actively encouraged to take the following actions:

Enable energy saving computer settings.
Switch off the monitor when you step away from your computer.
Utilize electronic agendas, syllabi, course materials, and filing options.
Switch off the lights when you leave your office, classroom or conference room.
Dress for the weather! Put on a sweater before you turn up the heat.
Take the stairs instead of the elevator.
Utilize the Holiday Energy Saving Checklist.


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

CSU has a JCI Metasys campus wide Building Automation System controlling in excess of 24,000 points including space temperatures, season, CO2 concentration, etc.


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

The Campus-Wide Energy Conservation Program included an exterior LED lighting upgrade project which provided for complete retrofits and replacements of parking lot lighting, parking garage lighting, and walkway and sidewalk lighting throughout the entire campus, totaling nearly 1,700 new exterior LED fixtures. This project resulted in utility savings, increased efficiency and improved optical control. LED lighting upgrades happen on a continual basis as new fixtures are needed and as funding allows. Utility program rebates are captured and reinvested in lighting upgrades.

The Office of the University Architect includes LED guidelines in their A/E specifications document.

LIGHTING
265000.1 General Specifications: A. All new lighting designs shall incorporate only LED luminaires.


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

The CSU Administration Center utilizes geothermal heating.


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

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

CSU invested $52M in energy conservation measures such as LED lighting, high efficiency fume hoods, improved utility metering, HVAC upgrades, and a new high efficiency chilled water plant as part of the Campus-Wide Energy Conservation Program. This program was funded through guaranteed energy and maintenance savings.

Energy misers installed on vending machines reduce electricity consumption of the machines by 41% annually. 70 energy misers were installed during FY 2016. They utilize occupancy sensors to power down the machines when the surrounding area is vacant thus reducing operating costs and greenhouse gas emissions.
