The state of New York requested that the U.S. Department of Energy's (DOE's) Building Energy Codes Program (BECP) provide an analysis of the impacts of adoption of ASHRAE Standard 90.1-2007. New York State is unique among states in requiring a ten-year payback for energy code measures. BECP based this analysis on the results of a nationwide, state-by-state code comparison for DOE. This analysis indicates that the adoption of ASHRAE Standard 90.1-2007 is cost-effective under New York’s requirements for all buildings in New York.

The purpose of this analysis is to examine the cost-effectiveness of the 2013 edition of ANSI/ASHRAE/IES1 Standard 90.1 (ANSI/ASHRAE/IES 2013). PNNL analyzed the cost-effectiveness of changes in Standard 90.1 from 90.1-2010 to 90.1-2013, as applied in commercial buildings across 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 ASHRAE Standard Standing Project Committee (SSPC) 90.1. The ASHRAE process, however, does not include analysis of the cost-effectiveness of the entire package of addenda from one edition of the standard to the next, which is of particular interest to adopting State and local governments. 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.

This technical support document (TSD) is designed to explain the technical basis for the COMcheck software as originally developed based on the ANSI/ASHRAE/IES Standard 90.1-1989 (Standard 90.1-1989). Documentation for other national model codes and standards and specific state energy codes supported in COMcheck has been added to this report as appendices. These appendices are intended to provide technical documentation for features specific to the supported codes and for any changes made for state-specific codes that differ from the standard features that support compliance with the national model codes and standards. Beginning with COMcheck version 3.8.0, support for 90.1-1989, 90.1-1999, and the 1998 IECC and version 3.9.0 support for 2000 and 2001 IECC are no longer included, but those sections remain in this document for reference purposes.

The intent of the vestibule requirement is to reduce infiltration of air into a space, thereby addressing energy conservation and comfort issues for occupants located near primary entrance doors. The majority of infiltration comes through primary entrance doors that are typically used to access public areas, and have higher usage rates than doors classified for personnel use. Vestibules can reduce the infiltration losses (or gains) from wind and stack effects by creating an air lock entry.
