Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 100,338 MMBtu 99,521 MMBtu
Electricity from on-site renewables 1,662 MMBtu 1,509 MMBtu
District steam/hot water (sourced from offsite) 0 MMBtu 0 MMBtu
Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) 115,798 MMBtu 120,462 MMBtu
Total 217,798 MMBtu 221,492 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year Jan. 1, 2017 Jan. 1, 2018
Baseline Year Jan. 1, 2012 Jan. 1, 2013

A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 3,134,598 Gross square feet 2,925,322 Gross square feet

Source-site ratio for grid-purchased electricity:

Total building energy consumption per unit of floor area:
Performance Year Baseline Year
Site energy 0.07 MMBtu per square foot 0.08 MMBtu per square foot
Source energy 0.14 MMBtu per square foot 0.15 MMBtu per square foot

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

Degree days, performance year (base 65 °F / 18 °C):
Degree days (see help icon above)
Heating degree days 2,778 Degree-Days (°F)
Cooling degree days 2,379 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 87,934 Square feet
Healthcare space 13,013 Square feet
Other energy intensive space

EUI-adjusted floor area, performance year:
3,449,120 Gross square feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
12.24 Btu / GSF / Degree-Day (°F)

Documentation (e.g. spreadsheet or utility records) to support the performance year energy consumption figures reported above:

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):

Chico State Green Campus Program

Who we are:

We are a student group working out of the Institute for Sustainable Development focused on promoting resource conservation and environmental stewardship to the Chico State Campus Community.

How we do this:

We do this by implementing creative student-led energy and water efficiency projects and by engaging the campus community in conservation campaigns and outreach events.

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):

Through the campus EMS system, as well as a campus wide scheduling program for classes and events, the central plant references this information to determine when building temperatures are allowed to go outside the posted range. This also allows operators to curtail building fans to reduce power consumption.

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

Yes, two classrooms have been modified to include LED lighting in existing recessed can lights. Several exterior lights are being upgraded to LED lights as well.

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


A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):


A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):
