Performance of Energy Management Systems
نویسنده
چکیده
Performance of building Energy Management Systems (EMS) has been controversial in several studies due to lack of measured energy savings, changes in building use or operation, other changes that simultaneously affect building energy use, equipment malfunction, or weather normalization. This study evaluated energy savings in 20 buildings that have EMS installed to control HVAC. The buildings were selected to have currently available EMS models, and an absence of other factors that would significantly affect energy use. Utility energy bills were corrected for weather variations.
