ML-11-009 -- Targeting Residential Energy Reduction for City Utilities Using Historical Electrical Utility Data and Readily Available Building Data PDF

Energy use data for the eight-year period 2003–2010 was analyzed for over 1200 single family residences in Village of Yellow Springs, Ohio. Electricity, natural gas, residential building, and weather databases are merged to permit determination of the energy intensity of each home in the village. The energy use intensity for each home is disaggregated into weather independent and weather dependent electric and natural gas use. This use is compared to typical baseline, cooling, and heating energy use for the region. From this comparison, priority homes are identified for energy reduction investment. Collective potential low cost energy reduction is estimated for the community. Energy reduction of greater than 41% is determined to be easily achievable. Finally, a process is established, beginning with individual home energy report cards, for turning the analysis and predictions into energy reduction action.
