Total energy consumption (all sources, transportation fuels excluded), performance year:
607,779.81 MMBtu

Clean and renewable energy from the following sources::
Performance Year
Option 1: Clean and renewable electricity generated on-site during the performance year and for which the institution retains or has retired the associated environmental attributes 941 MMBtu
Option 2: Non-electric renewable energy generated on-site 0 MMBtu
Option 3: 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 0 MMBtu
Option 4: Purchased third-party certified RECs and similar renewable energy products (including renewable electricity purchased through a certified green power purchasing option) 60,777.98 MMBtu

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

NAU has a 163 kW photovoltaic farm on its south campus.
The system was donated by APS provides up to 20 percent of the electricity for the LEED Platinum Applied Research and Development (ARD) building. The system was down for part of 2013 so our "energy generated" MMBtu is a conservative estimate.

NAU has a 2.4 kW SkyStream wind turbine turbine next to the ARD building.

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 70 percent of the domestic hot water is provided by 102 solar thermal panels on the building's roof. This renewable energy source exceeds six percent of the total building energy usage.

A brief description of off-site, institution-catalyzed, renewable electricity generating devices:

A brief description of the RECs and/or similar renewable energy products:

NAU buys 10% from APS's Green Energy Program.
