High Efficiency Window A/C Units
NORESCO replaced new window-mounted air conditioning units with new high efficiency units. The efficiency improvements will generate electricity savings while providing greater equipment reliability and occupant comfort. The new units will also be equipped with occupancy controls to reduce the operating hours and achieve additional electricity savings.
Steam and Electric Meters
NORESCO Furnished and installed a steam and electric meters at Mackal, Tootell and Keaney. These meters will enable the University to accurately determine and allocate utility usage and costs, but do not provide any direct energy cost savings.
MEMORIAL UNION Lighting Improvements
NORESCO installed a new super T8 system featuring highly efficient electronic ballast and long-life lamp combinations as well as retrofit existing fixtures with the same super T8 system or energy efficient compact fluorescent lamps. Existing fluorescent fixtures were also modified to increase their efficiency. Fifty-six incandescent fixtures were retrofitted with new compact fluorescent lamps or replaced with new linear fluorescent fixtures. The few remaining fluorescent and incandescent exit signs were replaced with new high efficiency exit signs containing LED lamps.
Lighting Occupancy Controls
NORESCO installed occupancy controls to turn off lighting in specific areas including all classroom and office areas as well as halls and bathrooms.
New Electric Chiller & Combined Chilled Water Loops
NORESCO removed an inefficient electric chiller that was in poor operating condition and replaced it with a new 300 ton centrifugal chiller equipped with variable speed drive for optimal compressor performance. The chiller was provided complete with micro-processor controls. Work also included modification of the existing CHW/CW hydronic loops and the 208 V electrical services from the main distribution panel to the chiller. The chiller was set and installed in accordance with all manufacturers’ recommendations.
Energy Management System
NORESCO installed a new direct digital control system. The system will provide improved occupant comfort and increased reliability, and will achieve savings through the increased operating efficiency of the HVAC systems under its control.
