Over fifty percent of Concordia's electricity is provided by renewable energy through Moorhead Public Service. Hydroelectric power is generated from dams along the Missouri River. Wind power is acquired from turbines in Rugby, N.D. and Worthington, Marshall and Odin, Minn.
The college is actively investigating the possibility of increasing this percentage by investing in solar energy. In 2014, a solar audit of the campus was completed by Dragonfly, which identified Knutson Campus Center and Olson Forum as the best locations for roof-top solar panels. An analysis of the financial and logistical issues in underway in the hope that a solar array can be installed within the next 12-18 months.
Monitoring and Reducing Energy Use
Facilities Management spends substantial time and effort on identifying opportunities to improve building performance so as save energy while increasing occupancy comfort.
Electric meters have been installed on most building and are connected to an online Building Dashboard, enabling students and others to track electricity usage by building and to see the results of energy saving measures.
Some of what Facilities Management has done:
- Moved to using variable frequency drives on fan and pump motors (energy savings of 18%)
- Retrofitted fluorescent light fixtures in Olson Forum (reduce consumption by 42%)
- Replaced incandescent lights with fluorescent and LED fixtures in the theater
- Replaced old windows and doors
- Replaced inefficient temperature controls
- Installed motion sensors for lighting
- Upgrades to the Heating and Cooling Plant to reduce the amount of energy to heat campus buildings by 20-30% per year.
