As UM continues to address deferred maintenance and pursue energy savings, energy conservation projects provide the double benefit of reducing our emissions footprint and reducing utilities expenses. Below is a short list of some of the energy and water conservation projects that have been recently completed or are in progress.

Adams Center Arena Lighting

Dimmable LED luminaires and wireless lighting controls were used to bring down ROI and allow for multiple scene settings, so the full output of the lighting system wasn't being used when it was not needed. Replacing existing metal halide luminaires in the arena and arena seating areas took the energy use from 78.81 kW to 20.73 kW, resulting in a savings of 58.08 kW when the lights are at full output. There is further savings through the dimmed scene settings and the use of vacancy sensors within the arena to automatically shut the lights off when the space is not in use.

Adams Center Auxiliary Gyms

This project is on order and has not been completed, but switching out the existing (56) 1000W metal halide high bay luminaires with high efficiency LEDs, the aux gyms have gone from 61.6kW installed down to 18.7 kW. Wireless controls and dimming have been added for additional savings.

Irrigation Automation adjacent to Forestry building

Slated for May 2021, the turf area between University Hall, Forestry, and the Mansfield Library will receive updated and automated irrigation that will reduce water waste. By installing new fixtures, valves, and irrigation timers, watering can occur at night and can be customized to prevent overspray.

Lighting and Technology Improvements in Pantzer Hall

UM completed a full LED and controls retrofit for all of Pantzer Hall, using a mix of wireless controls to add occupancy and vacancy sensing in common rooms and areas, while also using the advantages of LEDs to add dimming into all dorm rooms. This is an additional energy savings as most users will set the dim level where they prefer it, then turn lights on and off at that level throughout their use of the space. Previous lighting load for the building was 61.4 kilowatts and the new LED load is 21.1 kW, for a reduction of 40.3 kW. Further savings will be realized through updated controls.

Urey Lecture Hall

UM completed a full LED and controls retrofit using high efficacy dimmable LED products and wireless occupancy and vacancy sensors to save additional energy. Replacing existing halogen fixtures in the space also significantly reduced the cooling load for the space. The initial lighting energy was 19.79 kilowatts, and is now 2.96 kilowatts, with a reduction of almost 17kW for one lecture hall!
