Project Summary


The hypothesis guiding this project was that a deemed savings model can be created based on the analysis and simplification of variables involving the operation of a small energy management system (EMS)—including market segment, load type, climate zone, building schedule, and building construction type. This was to be achieved by testing the reliability of thermostat-based EMS systems and collecting operational information to calibrate computer models and determine the feasibility of offering a deemed rebate for this technology. Although HVAC energy savings were shown in the assessment, their dependency on as-found conditions and multiple variables made it difficult to develop a calculated savings model appropriate for a deemed rebate approach.
