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 :
We have:
2 Installations of solar hot air heaters
3 Solar PV installations
2 Solar hot water installations
4 wind turbines
Non-electric renewable energy generated on-site, performance year:
A brief description of on-site renewable non-electric energy devices:
ARD's building solar thermal pre-heats water for kitchen and bathroom sinks.
At the Health and Learning Building 35 percent of the domestic hot water is provided by 51 solar thermal panels on the building's roof. This renewable energy source exceeds three percent of the total building energy usage.
We have two innovative solar hot air heating systems and a solar wall system: http://nau.edu/Green-NAU/Renewable/
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:
2015: 15%, unbundled RECs starting in Nov. of 2015
