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

The University is working with a Building Analytics System company called SkySpark to get all the meters within the university academics and housing networked. All the buildings within the university are sub-metered to study their individual performance and energy consumption. The data is made available to the students where they can work on different projects to come up with better solutions in reducing the energy load of the buildings.


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

Sonoma State University is in the process of deploying public-facing energy dashboards in high visibility areas as well as holding our first housing energy competition. The efforts will be expanded and with more enhanced communications to help educate and engage our students, faculty, staff, and our entire community.


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

Some of the University building's lighting systems have been retrofitted to LED lights. 5% of parking lots have been switched to LED lighting and is currently working on retrofitting the remaining parking lots. There is an upcoming building renovation project which will have all the lighting systems retrofitted to LED.
The university is also working with a lighting control system company to install motion sensors.


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

in 2000 Sonoma State University built the Environmental Technology Center, which is a model for low energy consumption accomplished through passive solar, active shade louvers, and other strategies employed to not only be a model but an ongoing educational tool.
