This presentation covers the PMP Energy Protocols, including Basic, Intermediate and Advanced methods for characterizing building energy performance. For the Basic protocols the required information includes: building characteristics and annual whole-building energy use of all fuels to calculate indices. At the Intermediate level, monthly or weekly data are used to calculate regression models of the building’s energy use versus the influencing variables. At the Advanced level the protocols utilize daily, hourly or sub-hourly data to refine the regression models and/or apply diagnostic measures using regression models or calibrated simulation. Examples of all three levels are provided.
