Part 1
This credit is based on energy inputs from offsite sources and electricity produced by onsite renewables. When the institution purchases one fuel and uses it to produce heat and/or power, you should enter only what is purchased. For example, if the institution purchases natural gas to fuel a CHP system and produce steam and electricity, only the purchased natural gas should be reported.
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 100,958 MMBtu | 135,837 MMBtu |
| Electricity from on-site renewables | 5,278 MMBtu | 0 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) | 128,603 MMBtu | 180,575 MMBtu |
| Total | 234,839 MMBtu | 316,412 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |
| Performance Year | July 1, 2016 | June 30, 2017 |
| Baseline Year | July 1, 2006 | June 30, 2007 |
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):
FY 2007 is the year that WSU became an ACUPCC signatory and made the commitment to become a carbon neutral campus. This is the year we have used as our baseline for all of our ACUPCC reports and all internal reporting.
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area of building space | 3,072,262 Gross square feet | 2,469,079 Gross square feet |
Source-site ratio for grid-purchased electricity:
3.14
Total building energy consumption per unit of floor area:
| Performance Year | Baseline Year | |
| Site energy | 0.08 MMBtu per square foot | 0.13 MMBtu per square foot |
| Source energy | 0.15 MMBtu per square foot | 0.25 MMBtu per square foot |
Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
40.31

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):
WSU's Energy & Sustainability Office manages the Green Department Certification Program which is a voluntary, incentive-based program, with the aim of improving sustainability practices and behaviors in energy efficiency, purchasing, transportation, etc. Approximately 30% of campus is actively involved in this program and is reducing their energy consumption. The Energy & Sustainability Office is working to recruit the rest of campus.
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
During business hours we have a heating set point of 70 degrees and a cooling set point of 74 degrees. When the buildings are unoccupied we have a heating set point of 55 degrees and a cooling set point of 83 degrees. Most campus buildings operate on building timers using the BAS (Building Automation System). The main campus uses Johnson Control's Metasys, and the Davis Campus uses Atkinson's Staeffa Talon.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LEDs are the current campus standard. All new buildings are built with LEDs and WSU is currently in the process of replacing all existing lights with LEDs. Approximately 40% of campus has been upgraded.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
WSU currently has two ground source well fields; one located underneath a parking lot and another located beneath the "Quad." These ground source fields interface with water-cooled variable refrigerant flow (VRF) system which allow energy exchange between rooms, between areas of buildings, between buildings, and ultimately between the campus and the earth. Buildings currently connected to the ground source system include Tracy Hall, Wattis Business, Miller Administration, Marriot Health (north), Campus Services, the Library and Lindquist Hall.
A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
N/A
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):
As of fall 2013 WSU has started recommissioning at least two buildings per year. Buildings with the poorest EUIs and largest number of occupant complaints have the highest priority for recommissioning. WSU employs two full time in-house staff who are responsible for commissioning and re-commissioning efforts.
