There is a great opportunity to make an impact by addressing the energy use and performance of existing buildings. In this webinar, speakers will discuss the use of Building Performance Standards (BPS) and outline best practices, tools, and financial incentives that can be leveraged to support BPS implementation.
62 Commercial Buildings were evaluated for compliance with the 2009 IECC/ASHRAE 90.1-2007 be-tween October 1, 2010 and June 30, 2011. Of that number, 17 buildings were eventually dropped from the study for several reasons: Building would not be completed within time frame and no similar building could be found to merge Project “died” prior to construction ever starting Building was completed or nearly so prior to first visit by Evaluator.
The objective of this report is to assess the compliance of newly-constructed single-family homes with the Vermont Residential Building Energy Standards (RBES). This analysis is part of a broader study of the single-family residential new construction market in Vermont.

This report presents the results of a Study on the rate of compliance with the New York State (NYS) energy code. The Study tested the protocols developed by the US Department of Energy to determine if NYS’s new and renovated residential and commercial buildings exceed the 90% compliance threshold that states will be will be required to meet by 2017 as part of ARRA legislation. This Study performed detailed plan review and field inspections on 44 newly constructed residential and 26 new commercial buildings. The Study also included interviews with policy makers, contractors, engineers, architects, and code officials; and surveys of architects, homeowners, builders, and code officials who planned, constructed and inspected renovations.
Nebraska Commercial Energy Code Compliance Report for the 2009 International Energy Conservation Code
The Nebraska Energy Office (NEO) commissioned Britt/Makela Group, Inc. (BMG) to assess compliance with the commercial provisions of the 2009 International Energy Conservation Code (IECC). The goals of the project were to:
- Assess compliance rates for projects that represented typical commercial construction in Nebraska
- Collect information on energy code compliance issues that could be used to establish a framework for future energy code implementation programs in the state.
This report provides the results and methodologies for the 2010-2011 Iowa Energy Code Pilot Study that was conducted by the Iowa Department of Public Safety, division of State Fire Marshal, State Building Code Bureau. This study was funded by the U.S. Department of Energy with support from Pacific Northwest National Laboratories – Building Energy Codes Project and the Midwest Energy Efficiency Alliance (MEEA). Preliminary work on the study began in May of 2010. A contract with MEEA was signed in October 2010 with work commencing on the study in January 2011. The primary goal of the study was to determine the rate of compliance with the 2009 International Energy Conservation Code throughout the state of Iowa. Secondary goals of the study were to determine average energy code inspection durations, provide training to local code officials and builders participating in the study, and to determine areas of improvement.
Measuring the Baseline Compliance Rate for Residential and Non-Residential Buildings in Illinois Against the 2009 International Energy Conservation Code
The goals of this study were threefold: 1) Provide feedback to the BECP on the implementation of the BECP protocol 2) Develop a preliminary pattern/range of the existing compliance rates of newly constructed residential dwellings and commercial buildings based on jurisdictions in Illinois that have adopted the building energy codes and 3) Identify areas where home performance and codes training and education activities could be improved or refocused. Measurements of a small sample set (10) of commercial buildings were also taken. Due to the insignificance sample size, a commercial compliance rate is not reported here.
Project Goal: Assess and record energy code compliance of buildings currently under construction, following the U.S. Department of Energy (DOE) processes, in compliance with the American Recovery and Reinvestment Act of 2009 (ARRA), and identify procedural changes in code enforcement and training needed to improve compliance rates.
This study was conducted to estimate as-built energy use characteristics for homes that were not part of the Energy Efficiency Fund New Construction Program (RNC) as a baseline for the RNC Program. Resulting information will be applied to estimation of the net effects of the RNC Program on efficiency improvements. Additionally, these results are used to establish preliminary estimates of User Defined Reference Home (UDRH) inputs to be used as baseline characteristics against which construction within the RNC Program can be compared. Findings are based on the results of on-site inspections, including Home Energy Rating System (HERS) ratings, of 69 homes that were not part of the RNC program, were completed from November 2009 through July 2011, and whose owners agreed to have their home inspected.
Residential New Construction Baseline Study of Building Characteristics Homes Built After 2001 Codes
Summary of the findings of the 2003 Residential New Construction Baseline Study conducted by Itron, Inc. under Pacific Gas & Electric (PG&E) management.1 KEMA-Xenergy conducted the on-site surveys. The RNC baseline study investigates energy efficiency in newly constructed single family homes throughout California. The study’s primary purpose is to provide information to residential new construction (RNC) program managers across the state, thereby allowing them to assess and address the effect of recent energy code changes on these programs.
From August 1997 to September 1999, one hundred new Arkansas homes were evaluated in two areas in the state where there was significant building activity in order to determine the energy performance of current building practices. One of the positive findings was that homes are now being built significantly tighter than a few years ago. Homes built in the early to in.id 1990's were experiencing an average of 0.5 natural air changes per hour (NACH), an acceptable level considered normal for new construction Only 24 homes in this evaluation had leakage rates exceeding 0.4 NACH; the majority of homes (58 percent) had leakage rates of 0.35 and under.

The Department of Energy (DOE) Building Energy Codes Program (BECP) periodically evaluates national and state-level impacts associated with energy codes in residential and commercial buildings. Pacific Northwest National Laboratory (PNNL), funded by DOE, conducted an assessment of the prospective impacts of national model building energy codes from 2010 through 2040.
This report describes solutions to the common PRM adoption challenges, including calculating energy savings by fuel type and electricity demand savings relative to current code and avoiding “fuel switching” when reporting savings of the proposed design relative to the current code. The calculations described in this technical support document are automated in the ASHRAE Standard 90.1 Performance Based Compliance Form and the Compliance Form Companion Tool

The State of Michigan is in the process of updating its current state residential energy code, which is an amended version of the 2015 International Energy Conservation Code (IECC) to the 2021 IECC. The Michigan Bureau of Construction Codes, a bureau within Licensing and Regulatory Affairs (LARA), requested a cost-effectiveness analysis, that considers the Michigan Stille-Derossett-Hale Single State Construction Code Act,1 comparing the current state residential energy code to the unamended 2021 IECC.
The resulting analysis shows that a home designed to comply with the residential provisions of the 2021 IECC would yield short-term and long-term consumer benefits compared to a home built to the Michigan-amended 2015 IECC.
This is to certify that the State of New York intends to adopt an updated version of the State Energy Conservation Construction Code (the “NYS Energy Code”) and the State of New York is seeking an extension from the Secretary pursuant to 42 U.S.C. §6833(c) in light of the fact that the State has made a good faith effort to comply with such requirements and has made significant progress in doing so. The updated version of the NYS Energy Code is anticipated to become effective in 2025.
With regard to commercial buildings, the Department of State has reviewed the provisions of the State’s commercial building code regarding energy efficiency and seeks an extension of time to update the NYS Energy Code’s provisions to meet or exceed the requirements of ASHRAE 90.1-2019 for eighteen (18) months or until January 28, 2025.
