NAU is committed to lowering our carbon footprint in order to create a more sustainable future for our campus and community. Through the purchasing and utilization of renewable, we are offsetting some of the negative externalities that result from our fossil fuel use and doing our part to support America’s transition to a clean energy economy. The campus is currently using renewable wind and solar technologies and is investigating opportunities to utilize the vast ponderosa pine forests around us for biomass electricity or heat production.

Solar PV – San Francisco Garage Accordion Closed
NAU’s electric utility, APS, is providing tens of thousands in annual subsidies to help make the project feasible. The Green Fund is contributing $1,000,000 a year for 10 years to advance contribute to the effort.
Install Date: April, 2017
Solar Air Heaters – Property Surplus Accordion Closed
NAU’s first on-campus solar thermal air panel system was installed in 2014 through a Green Fund proposal. The six-panel system was installed on the south side of the Property Surplus warehouse. The wall-mounted system is 24 feet wide by 8 feet high and can generate more than 40,000 BTUs per hour of fossil-free heat energy. This single installation reduces CO2e by over 3 tons per year.

Solar Hot Air and Solar PV at Construction Management Accordion Closed
Solar PV – South Field Accordion Closed
NAU’s solar field on-campus was generously donated by NAU’s utility company, APS. The system was installed in 2007 to accompany the LEED Platinum certification of the Applied Research and Development building. The 163-kilowatt photovoltaic system is designed to supply at least 20 percent of the ARD building’s electrical needs. The system originally tracked the sun east to west to maximize efficiency but the tracking system stopped working in 2012. In January of 2015 an engineering class submitted a Green Fund proposal to optimize the angle of the panels and put them at a 5 percent east facing slant. That effort should help to improve efficiency by at least 20%.
Solar PV – International Pavilion Accordion Closed
Located on the roof of the NAU International Pavilion is a 35 kw solar panel array system. The building was designed to use less electricity than what can be generated from the solar array. What this means is the building will use less energy than what it can produce which will allow more power into the power grid for other uses on campus. The pavilion is the first NAU academic building to have a solar power system and is targeted for NetZero or better energy use performance.

Solar Hot Water – ARD & HLC Accordion Closed
NAU’s LEED Gold Health and Learning Center (HLC) and the LEED Platinum Applied Research and Development (ARD) buildings both have hot water heating systems.
The HLC system is 102 panels, 5300 sq ft and supplies 70% of the HLC hot water use (6% of total building energy).
The ARD has 2 panels and helps to heat water for the shower and bathrooms.
Solar Wall – Distance Learning Accordion Closed
When project architect Burns Wald-Hopkins Shambach Architects started work on the new Distance Learning Facility at Northern Arizona University in Flagstaff, AZ, they were targeting a LEED® silver rating. In order to achieve this LEED® status they implemented a variety of green technologies. The most prominent green technology being a south-facing SolarWall® solar air heating system. The SolarWall® system was chosen because it provides fresh solar heated ventilation air in the winter, and acts as a shading screen during the summer. The SolarWall® system provides exceptional air quality for the classrooms, faculty offices, and a new television studio that make up the new building. The SolarWall® system also qualifies for up to 6 LEED® points.

Wind – HRM, ARD, and Solar Shack Accordion Closed
The campus has multiple wind turbines; one 2.4 kWh in front of the Hotel and Restaurant Management (HRM) building, one 2.4 kWh turbine next to the Applied Research and Development (ARD) building, two smaller turbines at the Solar Shack (NAU’s renewable energy testing facility). The data from all of these turbines is used in NAU engineering courses and by K-12 schools around the country.

Renewable Energy Credits Accordion Closed
What is a Renewable Energy Credit (REC)? Watch the U.S. EPA’s short video on “RECs: Making Green Power Possible”
The U.S. Environmental Protection Agency has designated NAU as the Conference Champion in EPA’S College & University Green Power Challenge!

In 2013, NAU began purchasing 10% of it’s electricity from APS’s Green Choice program
In 2015, we began purchasing 15% of our annual electricity from 3Degrees.
The Green-e certified projects we are supporting are from 100% wind farms.
