POWERHOUSE 18,500 PPHBOILERS

• Planning for the Energy Center commenced in the early 1990s to respond to problems with the aging and undersized campus heating system

• Provides all heating, cooling, hot water and some electricity for the campus

• Staffed by CCSU on a 24/7 basis since the Fall of 2004

• Equipment in the Energy Center

FUEL CELLFUEL CELL

• 1,400 kW Direct Fuel Cell power plant was installed in the Fall 2011 and delivering power by January 1, 2012

• Minimum electrical capacity 1,303 kW . Minimal steam capacity 1,600 lb/hr with three modes of operation.

• Grid Connected Mode (with or without existing E.C. generators)

• Grid Independent Mode (without the utility grid) MICRO GRID

• Island Hot Standby Mode (powering its own parasitic loads)

FUEL CELL FUEL CELL

• Phase 1 (completed October 2011): Consisted of energy efficient improvement measures to Copernicus Hall, and Vance Academic Center. Implementation cost $164,166.00. Total energy savings $111,592.00 with a 1.5 year payback. Additional incentive through CEEF, $3,753.50 when project was closed out.

• Phase 2 (funding request submitted): Energy efficient improvement measures to the Energy Center. Implementation cost $270,671.00. Total energy savings $192,332.00 with a 1.4 year payback. Additional incentive through CEEF, $54,026.27 when project is closed out.

RETRO-COMMISSIONING RETRO-COMMISSIONING

• Retrofitting of 500 lamps across the CCSU campus with energy saving Sylvania DG LED retrofit kits

• Lessen electrical usage without compromising safety and security

• Bulb life approximately 5 times a traditional lamp

• Annual reduction of 240,900 kWh with an approximate 41k cost savings

• Reduction of criteria pollutants such as sulfur oxide, nitrogen and carbon compounds

• Reduction of light pollution in accordance with the Dark Sky Initiative

LED REPLACEMENT PROJECTLED REPLACEMENT PROJECT

• 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.

OTHER CAMPUS WIDE ENERGY OTHER CAMPUS WIDE ENERGY EFFICIENCY PROJECTSEFFICIENCY PROJECTS

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
