This document lays out the U.S. Department of Energy’s (DOE’s) methodology for evaluating the cost-effectiveness of energy code and standard proposals and editions. The evaluation is applied to new provisions or editions of ANSI/ASHRAE/IES2 Standard 90.1 and the International Energy Conservation Code. The methodology follows standard life-cycle cost (LCC) economic analysis procedures.

Publication Date:

DOE supports the development of the International Code Council’s (ICC) International Energy Conservation Code (IECC), the national model code adopted by or forming the basis of residential energy codes promulgated by a majority of U.S. states, as well as other voluntary building energy codes. DOE performs a cost-effectiveness analysis of proposed modifications to the codes as part of that support and also performs an analysis of cost-effectiveness of new code versions.1 This document represents the methodology DOE uses in performing such analyses.
