The Loadshape Catalog, prepared for the Regional EM&V Forum by DNVGL, is a user-friendly spreadsheet compilation of any key energy and peak demand savings parameters (e.g. hours of use and coincidence factors) available from recent metering-based studies performed in the region. Criteria for inclusion in the Catalog included: parameters to be based on primary data collected for the study or vetted for relevance and the study, at least 10 sample points for simple end uses (e.g. indoor lighting) and at least 15 sample points for more complex end uses (VFDs or Refrigeration). The Catalog includes parameters from 31 studies performed over the last 7 years that cover diverse measures in the residential and C&I sectors. The sources used to populate the catalog are from the Northeast and the Mid-Atlantic States, with a majority from states in New England. The catalog was developed to extract results and any needed supporting information in a manner that would not require additional analysis of the source data by the end user.
The objective of the Load Shape Data Catalog is to help reduce the overall cost of impact evaluation by making available secondary data to either supplement or offset the need for new studies with primary data collection. It also gathers and structures information from regional studies that can be used to support users in several ways. The Load Shape Catalog exists to support user determination of annual energy and peak demand savings for regulatory reports, the calculation of capacity values in regional capacity markets, the estimation of capacity and energy benefits in program benefit-cost analyses and program emissions savings for the purpose of air quality regulation modeling. It can potentially increase consistency, timeliness, and/or quality of results used in development of energy program impacts.
The Loadshape Catalog Summary report provides both a brief overview of the catalog and recommendations for future research, based on critical review of data gaps – measures, programs, parameters – where new research could assist program administrators and others in planning or in developing energy program impacts. The length of time since the last study, the expected level of savings associated with the measure, the anticipated importance of a measure or technology moving forward and our general knowledge of the durability of program evaluation results informed the recommendations. Furthermore, recommendations presume that either a study performed in one jurisdiction is transferrable to another or that sampling techniques will ensure representation of all regions or jurisdictions. Also included is a brief high-level recommendation related to implications that new industry developments have for current and future EM&V practices.
