Residential Lighting End-Use Consumption

Relates News Icon

NEEA recently completed their Residential Building Stock Assessment. As part of the assessment, 100 homes in the Pacific Northwest were outfitted with equipment for metering a variety of end-uses, including lighting. As a result, household characteristics and lighting inventory data for over 1850 residences, and end-use metering data for over 2000 fixtures, is available for incorporation into the DOE Residential Lighting Estimation Framework. Organizations that are interested in providing funding for this effort, which would improve the accuracy of estimates in the Pacific Northwest and nationally, are encouraged to contact DOE at DOE.SSL.Updates@ee.doe.gov

The U.S. DOE Residential Lighting End-Use Consumption Study aims to improve the understanding of lighting energy usage in U.S. residential dwellings using a regional estimation framework. The framework allows for the estimation of lamp usage and energy consumption 1) nationally and by region of the United States, 2) by certain household characteristics, 3) by location within the home, 4) by certain lamp characteristics, and 5) by certain categorical cross-classifications.

By improving our understanding of residential lighting-energy usage and quantifying it across many different parameters, the new study will be of use to anyone doing energy estimates – such as utilities, market and investment analysts, and government agencies. It will also help manufacturers design products that not only better serve consumers' needs, but that maximize the energy savings that technologies like SSL make possible.

The framework was designed to incorporate new data collected under similar protocols – for example, by a state or regional organization – which creates opportunities to further improve estimation accuracy. Updates to this study will be considered if enough new data and funding for its analysis becomes available. Please contact us with any interest in funding additional data collection and/or analysis, or if you would like to be notified of updates to the study or the tool.
