Energy Reduction Initiative
Initiative
The intent of this initiative is to retrofit certain equipment in a manner that meets a prescriptive program offered by NStar. This will allow us to recognize rebates, annual cost savings and reduce our carbon footprint.
Energy Reduction/ Utility Savings
Estimated carbon dioxide reduction per year is 68.15 tons. Reduction relates to E-Bldg AHU 1, G-Bldg AHU 3, 4 and G exhaust fans 1, 2, 3 and 4.
Annual KWH savings: 243,215
Total KWH savings include:
CABR 98,367
EBRC 39,140
Evans 20,035
R-Bldg 24,580
L-Bldg 51,044
G-Bldg 34,050
