The 1 – 100 ENERGY STAR score for Single-Family Homes applies to single-family detached and attached homes. The objective of the ENERGY STAR score is to provide a fair assessment of the energy performance of a property relative to its peers, taking into account the climate, weather, and activities at the property. To identify the aspects of building activity that are significant drivers of energy use and then normalize for those factors, a statistical analysis of the peer building population is performed.
This 10-page document provides a technical overview of the calculation methodology underlying the Building Emissions Calculator. The methodology is described in two main sections:
Calculation of annual current/historical emissions for standard greenhouse gas emission accounting categories
Calculation of annual emissions for a forecast year, based on user-specified assumptions, for the same accounting categories
This document also includes emissions-factor lookup tables in the appendix.

The ENERGY STAR score for retail stores applies to both retail stores and wholesale club/supercenters. The objective of the ENERGY STAR score is meant to fairly assess how a property’s energy use measures up against similar properties considering the climate and business activities. A statistical analysis of the peer population is performed to identify the aspects of property activity that are significant drivers of energy use and to normalize for those same factors. The result of this analysis is an equation that predicts the energy use of a property, based on its business activities.
