In many states building code officials rely on certified, code-compliant simulations to determine whether or not a residence satisfies the energy code requirements using a performance-path analysis. In the United States, certification of residential code-complaint software is performed by the Residential Energy Services Network (RESNET). Unfortunately, significant differences in results can exist when one compares the ratings from one certified software program to the next. This paper explores some of these differences for an analysis of a code-complaint residence in Texas, and provides additional comparisons that may help identify possible reasons for these differences.
