Cost-effectiveness of ASHRAE Standard 90.1-2010 Compared to ASHRAE Standard 90.1-2007

The purpose of this analysis is to examine the cost-effectiveness of the 2010 edition of ANSI/ASHRAE/IES1 Standard 90.1. Standard 90.1 is the model energy standard for commercial and multi-family residential buildings over three floors (ECPA, Public Law 94-385). PNNL analyzed the cost-effectiveness of changes in Standard 90.1 from 90.1-2007 to 90.1-2010, as applied in the United States. During the development of new editions of Standard 90.1, the cost-effectiveness of individual changes (addenda) is often calculated to support the deliberations of Standard Standing Project Committee (SSPC) 90.1. The process does not include analysis of the cost-effectiveness of the entire package of addenda from one version of the standard to the next. Providing States with an analysis of cost-effectiveness may encourage more rapid adoption of newer editions of energy codes based on Standard 90.1. This information may also inform the development of future editions of Standard 90.1.
