A brief description of the carbon sinks, including vendor, project source, verification program and contract timeframes (as applicable):

The only offsets generated by WSU are via the on campus composting program. Estimated tons of CO2 equivalent are provided by SIMAP.

Adjusted net GHG emissions 12,929.86 Metric Tons of CO2 Equivalent 25,340.20 Metric Tons of CO2 Equivalent

Start and end dates of the performance year and baseline year (or three-year periods):
Performance year Baseline year

A brief description of when and why the GHG emissions 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.

A brief description of the institution’s GHG emissions reduction initiatives:

WSU has an aggressive energy efficiency and GHG emissions reduction program. In 2009, the University had an investment-grade audit completed by AMERESCO and all of the projects identified by the audit have been completed. Some of those initial projects included insulating the chilled water and steam lines throughout the district heating and cooling tunnels, upgrading to high efficiency florescent bulbs across all of campus, installing VFDs and upgrading motors, improving building insulation and glazing, and improving automation and controls.

WSU is now implementing its second wave of energy efficiency and renewable energy projects. For example, WSU is 80% of the way finished with an entire university-wide LED upgrade (both interior and exterior lights). And for the past six years, WSU has been completing full mechanical system upgrades on existing buildings to transition the building over to all-electric, high coefficient of performance variable refrigerant flow systems with Energy Recovery Ventilation systems. Two large ground source well fields have also been constructed on the Ogden campus and are tied into the campus chilled water loop. Utilizing VRF systems allows heat to be shared within buildings and coupling that technology with ground source systems, tied into the central chilled water plant, allows for heat to be shared between buildings as well. Therefore the need for simultaneous heating and cooling is eliminated and significant energy is saved. About 25% of campus has been converted to this system to date.

This strategy allows WSU to electrify its buildings and and eliminate the need for natural gas. Then the university will look to source that electricity from renewable sources. WSU has several small solar projects on campus but the largest project, a 1.85 MW array, was completed two years ago on the Davis Campus. This array provides all of the electricity that the Davis Campus needs. WSU also completed its largest solar array on the Ogden campus this past year.
