• Copernicus Garage lighting: 700 (150watt HPS)fixtures were replaced with 100 watt MH
• Welte Garage lighting: 216 (150 watt HPS) fixtures were replaced with 8 foot 4 lamp fluorescents, approximately 112 watts per fixture
• Combined average savings for two garages is approximately 4,000 kWh per month
• Square D Monitoring: provides the ability to monitor each buildings electrical load
• Infrared motion sensor lighting controls: Installed in various portions of campus to include hallways, classrooms, etc.

We will continue to:– Investigate any and all incentive programs
available– Research additional retro-commissioning and
continue with persistent strategies on existing retro-commissioning projects
– Educate and involve the campus community in energy conservation and sustainability efforts
– Stay committed to meeting the goals and efforts in the University’s Climate Action Plan
