Total energy consumption (all sources, excluding transportation fuels), performance year :
3,539,388 MMBtu

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:
25,350 MMBtu

A brief description of on-site renewable electricity generating devices :

Photovoltaic Panels at the NC Botanical Garden-
84 photovoltaic panels generate nearly 8% of the building’s electricity from sunlight. PV panels on the Bell Tower Parking Deck generate enough electricity to illuminate the stairwells.

A 1,000 kilowatt generator at Carolina North converts gas from the Orange County landfill into electricity for the grid. The University sells the electricity to Duke Energy and plans to ultimately use the waste heat for buildings at Carolina North. Also, in 2015, additional photovoltaic panels (20 kW) were installed on the Graham Memorial Student Union.


Non-electric renewable energy generated on-site, performance year:
0 MMBtu

A brief description of on-site renewable non-electric energy devices:

Solar Thermal Panels at Morrison Residence Hall- 172 panels mounted on the roof of all four building wings provide heat to the domestic hot water and building heating system. The residence hall’s plumbing system draws first on solar-heated water from a 6,000 gallon storage tank and adds steam-heated water when needed.

Geothermal wells at NC Botanical Garden- geothermal wells provide efficient heating and cooling. Twenty-six wells are 500 feet deep, four wells are 400 feet deep, and four wells are 100 feet deep. More than five miles of loop “plumbing” brings the earth’s 55 degrees Fahrenheit temperature to the surface.


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:
0 MMBtu

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:
0 MMBtu
