Title: | Updating Miscellaneous Electricity Loads and Appliance Energy in Home Energy Rating Systems and Building America Benchmark Procedures
|
|
Abstract:
|
This report covers miscellaneous electricity loads (MELs) and major appliance energy use in homes. It builds on earlier U.S. Department of Energy (DOE) reports on the same subject and incorporates the 2005 Residential Energy Consumption Survey (RECS) public use data set to determine how major appliance use is related to the number of bedrooms (as a surrogate for occupants) in existing homes. These data, coupled with existing and proposed DOE appliance testing and labeling standards, are then used to determine a set of baseline lighting and appliance end use standards for use in the HERS Reference and Building America Benchmark homes, which both use whole-house energy consumption to determine the degree of energy performance improvement from their respective baseline references. The report makes recommendations for revising the reference standards that are in currently use and provides mechanisms for expanding the number and types of lighting and major appliances that are considered to be rated features of a home.
