Comprehensive Energy Efficiency Treatment
Efficiency measures designed by OpTerra save the Colonnade hotel over $250,000 per year.
OpTerra provided a comprehensive energy conservation analysis of the Colonnade Hotel in Boston, Massachusetts that resulted in the identification and implementation of cost effective controls, lighting, chillers, and electrically commutated motor (ECM) technologies.
The existing Building Automation System (BAS) was replaced with a new system, complete with a computer-based front end with user-friendly interface for all the equipment tied to the existing BAS. The new BAS strategies included scheduling, set-back and optimum start/stop controls. The Colonnade’s Huntington Ballroom’s air handling units (AHU) were modified to accept return air. BAS controls were installed on the AHU’s existing outside air dampers and new return air dampers. Additionally, the BAS was programmed to set back these AHUs during unoccupied hours and to modulate the dampers to maintain room temperatures.
