A brief description of when and why the energy consumption baseline was adopted:
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.
Source-site ratio for imported electricity:
3
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 | 0.13 MMBtu per square foot | 0.24 MMBtu per square foot |
Percentage reduction in total source energy consumption per unit of floor area from baseline:
45.98

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
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:
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 80% 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." A third field is currently under construction and will come online with the new Noorda Engineering Building in 2022. 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 Lind Lecture, and Lindquist Hall.
A brief description of co-generation employed by the institution:

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
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. Efficiency projects are often identified and implemented through these efforts.
Also, WSU is also in the process of converting all buildings over to all-electric heat pump based HVAC systems. Approximately 25% of WSU's gross square footage has been converted over to these variable refrigerant flow (VRF) HVAC systems. VRF HVAC systems allow heat to be shared between spaces. These VRF buildings are then tied into our ground source fields (discussed above) via the campus chilled water plant.
