This workbook accompanies the report 'National Cost-Effectiveness of ANSI/ASHRAE/IES Standard 90.1-2016.' The report provides the full description of this project and the cost estimate methodology as well as some additional details on the cost estimate items.

This report is focused on the analysis of collected data in support of the development of an updated methodology to measure the impact of energy codes on commercial buildings and identify opportunities for savings through increased compliance. The primary goal was to analyze the data collected during the field study and determine the actual energy cost impact of each measure in a non-compliance situation. The energy impact results allowed for ranking the measures to identify which have the highest potential for lost savings.

This document attempts to answer the following questions: What is the potential value of increasing compliance with the energy code and which code requirements should be emphasized during these studies? Ultimately, these are the questions that policy makers, funders, and program implementers care about. To answer them, a far more sophisticated approach is needed, one that addresses not only the question of value, but also the resource requirements to determine that value.

This document updates commercial building construction weights for the purpose of estimating national and state-by-state energy savings impacts of changes made to various commercial energy codes and standards using dis-aggregate construction volume data for the years 2003‐2007.

This document updates commercial building construction weights for the purpose of estimating national and state-by-state energy savings impacts of changes made to various commercial energy codes and standards. A similar activity was last completed by PNNL in 2010 using disaggregate construction volume data for the years 2003‐2007. For the current update, PNNL reviewed the same data source with the latest construction data for the years 2003‐2018.

The U.S. Department of Energy (DOE) tasked Pacific Northwest National Laboratory (PNNL) with updating commercial building1 construction weights for the purpose of estimating national and state-by-state energy savings impacts of changes made to various commercial energy codes and standards. For commercial building analyses, PNNL typically uses a suite of 16 prototype buildings simulated in the 19 ASHRAE climate zones with 16 of them present in the United States. The 2008-2022 commercial building weighting factors were derived using the same approach employed to develop the 2003-2018 set (Lei et al, 2020).

This report summarizes technical analysis conducted by Pacific Northwest National Laboratory (PNNL), assessing expected end-use energy consumption in commercial buildings, based on recent editions of the model energy code for the commercial sector, ANSI/ASHRAE/IES Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings. An accompanying spreadsheet is available containing detailed end use data results from the Progress Indicator analysis.

This report provides an assessment as to whether new buildings constructed to the commercial energy efficiency provisions of the 2015 IECC would save energy and energy costs as compared to the 2012 IECC. PNNL also compared the energy performance of the 2015 IECC with the corresponding Standard 90.1-2013. The purpose of this analysis is to help states and local jurisdictions make informed decisions regarding model code adoption.

This report provides an assessment as to whether new buildings constructed to the commercial energy efficiency provisions of the 2018 IECC would save energy and energy costs as compared to the 2015 IECC. The Commercial Energy Efficiency chapter in the 2018 IECC allows users to either follow the provisions in the IECC or use Standard 90.1-2016 as an alternative compliance path. PNNL also compared the energy performance of the 2018 IECC with the corresponding Standard 90.1-2016 to help states and local jurisdictions make informed decisions regarding model code adoption.

This report provides an assessment as to whether new buildings constructed to the commercial energy efficiency provisions of the 2021 IECC would save energy and energy costs as compared to the 2018 IECC. The Commercial Energy Efficiency chapter in the 2021 IECC allows users to either follow the provisions in the IECC or use Standard 90.1-2019 as an alternative compliance path. As such, PNNL also compared the energy performance of the 2021 IECC with the corresponding Standard 90.1-2019 to help states and local jurisdictions make informed decisions regarding model code adoption.

Technical analysis performed in support of the Standard 90.1-2016 Determination.

To meet statutory requirements, DOE conducted an analysis to quantify the expected energy savings associated with Standard 90.1-2016. This report documents the methodology used to conduct the analysis. Based on the analysis, DOE has determined that the 2016 edition of the ANSI/ASHRAE/IES Standard 90.1 would improve overall energy efficiency in buildings subject to the code compared to the 2013 edition of Standard 90.1.

To meet the statutory requirement, DOE conducted an analysis to quantify the expected energy savings associated with Standard 90.1-2019. This report documents the methodology used to conduct the analysis. Based on the analysis, DOE preliminarily determined that the 2019 edition of the ANSI/ASHRAE/IES Standard 90.1 would improve overall energy efficiency in buildings subject to the code (compared to the 2016 edition of Standard 90.1). This report represents the final version of the analysis supporting DOE’s determination on Standard 90.1-2019.
