Total energy consumption (all sources, excluding transportation fuels), performance year :
Total clean and renewable electricity generated on site during the performance year and for which the institution retains or has retired the associated environmental attributes:
A brief description of on-site renewable electricity generating devices :
SOU currently has SOU has seven solar arrays on campus, totaling 392.24 kW of solar capacity. SOU's first solar array was installed on the Hannon Library in 2000. The 6kw solar array consists of 24 solar panels. In January 2019, SOU expanded on this system, adding an additional 55.65 kW of solar to the site. In total, the university has 1,435 solar panels on-site, including SolarWorld and Canadian Solar panels. Each individual system ranges in size from 23.8 kW to 82.5 kW. More information is available at https://inside.sou.edu/sustainable/energy.html.
Non-electric renewable energy generated on-site, performance year:
A brief description of on-site renewable non-electric energy devices:
SOU's Dining Hall and McLoughlin Residence Hall each have solar hot water systems installed to augment the natural gas domestic water heating. The system on McLoughlin Hall consists of an array of 16 flat plate solar collectors mounted on the roof, facing due south with a tilt of approximately 15 degrees from horizontal. Each solar collector is 48"x122". Total solar collector absorber area is 597.3 square feet. Efficiency of the collectors is 60.7%. The collectors are piped together on a glycol loop piped to a heat exchanger. The system has two 500 gallon solar preheat storage tanks.
The solar hot water system on the Dining Hall consists of an array of 8 flat plate solar collectors mounted on the roof, facing due south with a tilt of approximately 15 degrees from horizontal. Each solar collector is 48"x122". Total solar collector absorber area is 321.2 square feet. Efficiency of the collectors is 66.2%. The collectors are piped together on a glycol loop piped to a heat exchanger.
Total clean and renewable electricity generated by off-site projects that the institution catalyzed and for which the institution retains or has retired the associated environmental attributes, performance year:
A brief description of off-site, institution-catalyzed, renewable electricity generating devices:
Total third-party certified RECs, GOs and/or similar renewable energy products (including renewable electricity purchased through a utility-provided certified green power option) purchased during the performance year:
A brief description of the RECs, GOs and/or similar renewable energy products, including contract timeframes:
Through the student-initiated Green Fund, SOU formerly purchased RECs to offset 100% of the electricity consumed on campus and carbon offsets to offset 100% of the natural gas consumed on campus from the Bonneville Environmental Foundation. The RECS and carbon offsets purchased by B-E-F for SOU were from Green-e Energy certified wind energy facilities located in North America. In 2013, students voted to modify use of the Green Fund to offset 100% of the university's water use and fund renewable energy projects on campus, discontinuing purchase of RECs and carbon offsets in an effort to make our efforts more localized.
