When first hearing about Standard 100, most people think it is a commercial building energy efficiency standard. However, Standard 100 also establishes building energy performance requirements for five different residential building types using climate-dependent target tables derived from the 2009 Residential Energy Consumption Survey database. This presentation summarizes the derivation of these table entries, identify and characterize differences in methodology between Standard 90.2 revisions and Standard 100, and illustrate application of the target tables to real-world homes. Plans for further refinements to the Standard 100 performance calculations are also discussed.
