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.
| kWh | MMBtu | |
| Imported electricity | 39,214,701 Kilowatt-hours | 133,800.56 MMBtu |
| Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) | 0 Kilowatt-hours | 0 MMBtu |
Stationary fuels and thermal energy, baseline year (report MMBtu):
| MMBtu | |
| Stationary fuels used on-site to generate electricity and/or thermal energy | 180,575 MMBtu |
| Imported steam, hot water, and/or chilled water | 0 MMBtu |
Total site energy consumption, baseline year:
Baseline year building space

| Baseline period | July 1, 2006 | June 30, 2007 |
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 energy
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 |

Optional Fields
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 50% 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. More information abou the program can be found here: https://www.weber.edu/sustainability/green-department.html
A brief description of energy use standards and controls employed by the institution:
WSU employs three full time controls technicians who oversee and maintain our BAS (Building Automation System). The Ogden campus uses Johnson Control's Metasys, and the Davis Campus uses Atkinson's Staeffa Talon. All lighting is on occupancy sensors and all major equipment is scheduled by the Controls team for when the buildings are occupied and are programmed to operate with efficiency in mind.
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 three ground source well fields on the Ogden campus with plans to construct 3-4 more over the next 15 years. 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. Over 33% of WSU's square footage has been transitioned over to Variable Refrigerant Flow systems and WSU completed a strategic plan in 2020 which provides the roadmap for converting the rest of WSU's square footage so that campus buildings are all-electric and capable of sourcing their energy from renewable sources.
A brief description of co-generation employed by the institution:
N/A
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 one to 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 (VRF). Approximately 33% 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.
When it comes to sourcing equipment and applicances, EnergySTAR certified products are the campus standard.
