Comprehensive Energy Efficiency Treatment

design and installation of new efficient chiller plant, HVAC improvements and lighting upgrades.

OpTerra provided a comprehensive energy conservation analysis of Cabot's Business Development Center in Billerica, Massachusetts that resulted in the identification of cost effective controls, lighting and central chiller plant projects. OpTerra contracted to install the measures for Cabot that resulted in annual savings of 1,200,000 kWh and 20,000 therms of gas. The projects qualified for over $300,000 of utility incentives, and saved $110,000 annually.

Extensive modification to the chiller plant included installation of a new 470 ton chiller, conversion to primary/secondary pumping, and installation of a new efficient cooling tower.
