"---" indicates that no data was submitted for this field

Figures needed to determine total building energy consumption:
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:

Total building energy consumption per unit of floor area:
Performance Year Baseline Year
Site energy 0.08 MMBtu / GSF 0.13 MMBtu / GSF
Source energy 0.15 MMBtu / GSF 0.25 MMBtu / GSF

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 5,655 Degree-Days (°F)
Cooling degree days 1,145 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 30,001 Square Feet
Healthcare space 7,941 Square Feet
Other energy intensive space

EUI-adjusted floor area, performance year:
3,175,989 Gross Square Feet

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

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):


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.
