Cost-effectiveness Analysis for ASHRAE 90.1-2013 - Arizona
Document Number: PNNL-25018 | Document Type: Analysis, Cost-effectiveness | Publication Date:

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 for each state in the United States.

Cost-effectiveness Analysis of 2015 IECC - South Dakota
Document Number: PNNL-24936 Rev-1 | Document Type: Analysis, Cost-effectiveness | Publication Date:

These analyses evaluate the cost-effectiveness of the prescriptive path of the 2015 edition of the International Energy Conservation Code (IECC), relative to the 2012 and 2009 IECC for all 50 states and the District of Columbia. The analysis covers one- and two-family dwelling units, town-homes, and low-rise multifamily residential buildings covered by the residential provisions of the 2015 IECC.

Methodology for Evaluating Cost-effectiveness of Commercial Energy Code Changes
Document Number: PNNL-23923 Rev1 | Document Type: Analysis, Cost-effectiveness | Publication Date:

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.

Methodology for Evaluating Cost-Effectiveness of Residential Energy Code Changes
Document Number: PNNL-21294 Rev 1 | Document Type: Analysis, Cost-effectiveness | 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.
