Page Focus: Adoption, Code Development, Compliance, Enforcement

Buildings account for almost 40% of the energy used in the United States and, as a direct result of that use, our environment and economy are impacted. Building energy codes and standards provide an effective response. The Building Energy Codes Program designed the Adoption, Compliance, and Enforcement (ACE) Learning Series for those in the building industry having the greatest potential to influence the adoption of and compliance with building energy codes and standards. Each toolkit in the ACE Learning Series delivers essential information to enable designers, specifiers, builders, building owners, policy makers, code officials, and others involved in building design and construction to understand the important role building energy codes play in helping us all address our energy, economic, and environmental challenges.

This report documents the progress indicator (PI) process and analysis that Pacific Northwest National Laboratory (PNNL) developed to evaluate the potential energy savings from the application of ASHRAE Standard 90.1-2010 to building design and construction compared to the application of ASHRAE Standard 90.1-2004. The report describes PNNL’s EnergyPlus simulation framework, and the building prototype simulation models. The combined upgrades from ASHRAE Standard 90.1 -2004 to ASHRAE Standard 90.1-2010 are described, and consist of a total of 153 approved addenda (44 addenda to ASHRAE Standard 90.1-2007 and 109 addenda to ASHRAE Standard 90.1-2010). PNNL reviewed and considered all 153 addenda for quantitative analysis in the PI process. Fifty-three of those addenda are included in the quantitative analysis. This report provides information on the categorization of all of the addenda, a summary of the content, and a more in-depth explanation of the impact and modeling of the 53...

This report provides the qualitative analysis of all addenda to ANSI/ASHRAE/IES1 Standard 90.1-2010 (referred to as Standard 90.1-2010 or 2010 edition) that were included in ANSI/ASHRAE/IES Standard 90.1-2013 (referred to as Standard 90.1-2013 or 2013 edition). All addenda in creating Standard 90.1-2013 were evaluated for their projected impact on energy efficiency. Each addendum was characterized as having a positive, neutral, or negative impact on overall building energy efficiency.

Publication Date: March 2014
Page Focus: Code Development

This report provides a preliminary qualitative analysis of all addenda to ANSI/ASHRAE/IES Standard 90.1-2010 (referred to as Standard 90.1-2010 or 2010 edition) that were included in ANSI/ASHRAE/IES Standard 90.1-2013 (referred to as Standard 90.1-2013 or 2013 edition). All addenda in creating Standard 90.1-2013 were evaluated for their projected impact on energy efficiency. Each addendum was characterized as having a positive, neutral, or negative impact on overall building energy efficiency.

Document type: Analysis, Determination
Publication Date: March 2014
Page Focus: Code Development

This report provides a preliminary quantitative analysis to assess whether buildings constructed according to the requirements of ANSI/ASHRAE/IES Standard 90.1-2013 would result in improved energy efficiency in commercial buildings. The preliminary analysis considered each of the 110 addenda to Standard 90.1-2010 that were included in Standard 90.1-2013. PNNL reviewed all addenda included by ASHRAE in creating Standard 90.1-2013 from Standard 90.1-2010, and considered their combined impact on a suite of prototype building models across all U.S. climate zones. Most addenda were deemed to have little quantifiable impact on building efficiency for the purpose of DOE’s preliminary determination. However, out of the 110 total addenda, 30 were identified as having a measureable and quantifiable impact.

As our country continues to focus on saving energy and reducing emissions in the face of global climate change, it is turning to the building sector for viable solutions. The effects of energy use in residential and commercial buildings are nationwide, worldwide and varied. In the U.S. alone, residential and commercial buildings account for 40% of all energy consumption and 70% of electricity usage.

The purpose of this analysis is to assess the relative energy and energy cost performance of commercial buildings designed to meet the requirements found in the commercial energy efficiency provisions of the International Energy Conservation Code (IECC). Section 304(b) of the Energy Conservation and Production Act (ECPA), as amended, requires the Secretary of Energy to make a determination each time a revised version of ASHRAE Standard 90.1 is published with respect to whether the revised standard would improve energy efficiency in commercial buildings. As many states have historically adopted the IECC for both residential and commercial buildings, PNNL has evaluated the impacts of the commercial provisions of the 2006, 2009, and 2012 editions of the IECC. PNNL also compared energy performance with corresponding editions of ANSI/ASHRAE/IES Standard 90.1 to help states and local jurisdictions make informed decisions regarding model code adoption.

Since the last publication of the commercial prototype building models, PNNL has made numerous enhancements to the original prototype models compliant with the 2004, 2007, and 2010 editions of Standard 90.1. Those enhancements are described here and were made for several reasons: (1) to change or improve prototype design assumptions; (2) to improve simulation accuracy; (3) to improve simulation infrastructure; and (4) to add additional detail to the models needed to capture certain energy impacts from Standard 90.1 improvements.

Pacific Northwest National Laboratory analyzed the relationship between the Residential Energy Services Network (RESNET) Home Energy Rating System (HERS) Index and the traditional simulation-based Performance Path used in the International Energy Conservation Code (IECC). The analysis evaluates, for a single-family residence with various characteristics, the ranges of HERS Index values that would imply compliance with the 2012 IECC Performance Path. Several building characteristics considered likely to result in quantifiable differences in the outcomes of the two approaches, or otherwise believed to be of interest to code developers and policy makers, are considered in the analysis.

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/IES Standard 90.1 and the International Energy Conservation Code. The methodology follows standard life-cycle cost (LCC) economic analysis procedures. Cost-effectiveness evaluation requires three steps: 1) evaluating the energy and energy cost savings of code changes, 2) evaluating the incremental and replacement costs related to the changes, and 3) determining the cost-effectiveness of energy code changes based on those costs and savings over time.

The U.S. Department of Energy's (DOE's) Building Energy Codes Program has developed and established a methodology for evaluating the energy and economic performance of residential energy codes. This methodology serves two primary purposes. First, as DOE participates in the consensus processes of the International Code Council, the methodology described herein will be used by DOE to ensure that its proposals are both energy efficient and cost effective. Second, when a new version of the International Energy Conservation Code is published, DOE will evaluate the new code as a whole to establish expected energy savings and cost effectiveness, which will help states and local jurisdictions interested in adopting the new codes. DOE's measure of cost-effectiveness balances longer-term energy savings against additions to initial costs through a life-cycle cost perspective.
