Building energy modeling consistency has and will continue to be an area of concern for the BEM community. As BEM is relied on more and more as part of the United States' and ASHRAE's commitment to reduce energy consumption, more accurate and better calibrated output from the models is critical to this energy saving effort. Continuing with the recent successful session from the 2012 Winter Conference on the same topic, this session shows best-practice methods to identify plausible causes of discrepancies between measured and modeled performance based on utility-level data, identifying causes of discrepancies, and understanding the challenges encountered. A number of case studies from various building types are presented. Some of these studies also compare post ECM utility data with the original simulation data.
