19.33 Btu / GSF / Degree-Day (°F)

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.

Electricity use, baseline year (report kWh):

	kWh	MMBtu
Imported electricity	19,879,616 Kilowatt-hours	67,829.25 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems)	65,734 Kilowatt-hours	224.28 MMBtu

Stationary fuels and thermal energy, baseline year (report MMBtu):

	MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy	104,670.10 MMBtu
Imported steam, hot water, and/or chilled water	0 MMBtu

Total site energy consumption, baseline year:

172,723.63 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

2,433,813 Gross square feet

Baseline period

Start and end dates of the baseline year (or 3-year period):

	Start date	End date
Baseline period	July 1, 2017	June 30, 2018

A brief description of when and why the energy consumption baseline was adopted:

Source energy

Source-site ratio for imported electricity:

3.14

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	0.07 MMBtu per square foot	0.13 MMBtu per square foot
Baseline year	0.07 MMBtu per square foot	0.13 MMBtu per square foot

Metric used in scoring for Part 2

Percentage reduction in total source energy consumption per unit of floor area from baseline:

0.37

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.
