Energy Use Analysis
The purpose of the energy use analysis is to determine the energy savings potential of appliances or equipment that have a more efficient design than the current stock of equipment in the same operating conditions. The general approach involves calculating national energy consumption for the base case that consists of the currently existing inventory of appliances and then for each potential standard level being analyzed, and the energy savings will be calculated as the difference in energy consumption between the base case and the standards cases. To perform this calculation EES uses a spreadsheet model that accounts for the stock of equipment affected by the proposed standards. The energy savings are measured over the entire lifetime of products purchased over a multi-year projection period. The results of this analysis are used as input to the life-cycle cost (LCC) and payback period (PBP) analysis, national impacts analysis (NIA), and several other downstream analyses.
