摘 要：In this paper, we introduce an innovative software approach for building energyefficiency analysis. It takes real-time data from meters and sensors in the building, analyzes energy usage, and helps building managers to save energy.Buildings consume 40% of the $370 Billion annual energy cost in U.S., and 30% of energy consumption is wasted. Existing building control systems waste energy because of old HVAC(Heating, Ventilation and Air Conditioning) equipment, lack of maintenance, over-cooling, overventilation and other reasons. More and more sensor nodes are deployed in the building forenergy monitoring, but the large amounts of data generated are not fully utilized. On the other hand, building scientists use energy models to do energy efficiency analysis, but the models theyuse are not accurate and it takes a long time to develop a full model.
