OP-T2-17: Energy Management System
Energy & Environmental Project Coordinator
Does the institution use a centralized energy management system that allows it to track energy consumption and performance in multiple buildings in a central location?:
A brief description of the management system:
The building management system (BMS) currently interconnects 40 buildings with either remote monitoring or control functionality. In terms of the absolute number of buildings with BMSs the coverage is small (~30%) but the buildings with BMSs are the largest buildings on campus so in terms of square footage (or energy usage) the BMS coverage is extensive. The BMS primarily monitors and controls space temperatures, humidity, and HVAC functions rather than lighting. Lighting is generally controlled with local occupancy sensors, daylight sensors, or photocells. One building that opened during the past year has its lighting system controls integrated into its BMS.
The percentage of building space monitored with a centralized energy management system:
A description of what systems are shut down during unoccupied periods:
Air-handler supply and return fans, chillers, primary and secondary chilled water pumps, reheat system pumps, and some parking garage exhaust fans.
The website URL where information about the institution's use of the technology is available:
Energy use in existing buildings comprises 80 percent of the university's GHG emissions. In the first years of implementing the Climate Action Plan, GW has prioritized improving building energy efficiency and enhancing IT systems that result in energy use reductions.
