Energy Support Program
Drew initiated an Energy Support Program in January 2010. During the first six months of the Energy Support program, Drew achieved a 9 percent reduction in overall energy consumption while saving $65,848 and reducing carbon emissions by 250 metric tons of eCO2 – equivalent to permanently removing 49 passenger vehicles from New Jersey roadways.
Actions taken to reduce energy consumption included more efficient building scheduling, reduced steam pressure at the central heating plant, replacing older window air-conditioning units in Tilghman House with new units.
Energy Conservation in Capital Projects
Drew University has taken steps to address the goal of cost reduction through energy conservation. The capital improvements previously undertaken include implementation of the philosophy of plant clustering for heating and cooling, replacement of older windows with newer, more insulating windows, and the installation of occupancy sensors combined with the replacement of older, inefficient light sources, i.e. light bulbs, ballasts, fixtures, and other lighting components.
The philosophy of plant clustering has been implemented through the Baldwin Mini-Plant, Commons Mini-Plant, and most recently the Welch Mini-Plant. The upgrade of the Central Heating Plant would also fall into this category. The implementation philosophy can reduce electric and natural gas consumption. This reduction in consumption is dependent upon a number of factors, including, but not limited to, efficiency of the systems being replaced and the habits of the occupants.
The University has replaced many older single pane windows with double pane thermal windows in Riker, Hoyt-Bowne, Brothers College, Hall of Sciences, Seminary Hall, Lewis House, Hannan House, Wendel, Tipple, Baldwin Hall, Haselton, and Welch-Holloway within the last 15 years. The replacement of single pane with storm windows with double pane windows can reduce average heat loss through the windows by approximately 20%. These savings represent the heat lost through the glazing only, and do not include infiltration (air leakage) which will most likely also be reduced. Finally, in S.W. Bowne, many broken windows were repaired, the stained glass window in the Great Hall was rebuilt, and the office windows had fixed storm panels installed.
The occupancy sensors are installed where they will not present a safety hazard, including offices, classroom, corridors, mechanical rooms, and restrooms, in Brothers College, the Hall of Sciences, Learning Center, and Simon Forum.
To reduce fuel use, Facilities owns 7 electric cart vehicles. Drew owns a total of 11 electric cart vehicles and only one gasoline powered cart vehicle.
