The U.S. Department of Energy submitted 56 code change proposals for the International Code Council's (ICC) Code Development Cycle produced the 2012 I-codes. Thirty-two of the proposals were primarily related to commercial buildings, 24 were for residential buildings. The proposals were mainly to the International Energy Conservation Code (IECC) though most of the residential proposals also applied to Chapter 11 of the International Residential Code.The central theme of the DOE proposals is to improve energy efficiency. Additionally, for commercial buildings DOE attempted to make the IECC more consistent with ASHRAE Standard 90.1. Finally, some proposals were not intended to change requirements but rather improve the usability of the codes, fix wording, correct errors, etc.DOE invited discussion on these proposals and on preparations for the ICC code hearings that took place from October 24 through November 11, 2009, in Baltimore, Maryland.The proposals are available for download in...

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.

The New Buildings Institute (NBI) and American Institute of Architects believe that the 20% to 30% reductions in commercial and high-rise residential building energy use based on this proposal are practical, feasible, and necessary. This proposal employs improvements to design practices and use of widely available products to improve energy efficiency. Many of the elements have been previously published in NBI’s Core Performance Guide and implemented in programs or codes at the local and state levels. Incorporating these enhancements in a model code will help move building practices and markets more quickly, addressing national concerns for energy and the environment in a pragmatic and cost-effective way.

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.

More than 200,000 homes are factory built in the United States each year to the federally preemptive Manufactured Housing Construction and Safety Standards, mandated by the U.S. Department of Housing and Urban Development (HUD). This paper analyzes national energy use and savings potential from improvements to thermal distribution system efficiency, thermal envelopes, and heating, ventilation and air conditioning (HVAC) equipment over what is currently required by HUD code. Estimated energy savings over current HUD code are provided for four cases: National Fire Protection Association Standard 501-2005, the 2006 International Energy Conservation Code, the U.S. Environmental Protection Agency’s ENERGY STAR manufactured housing guidelines , and Best Practice, based on the U.S. Department of Energy’s Building America Industrialized Housing Partnership program home built in the Pacific Northwest. Savings estimates are also provided from improved HVAC system efficiencies,...

Energy-efficiency requirements were developed for manufactured homes, which are regulated by the U.S. Department of Housing and Urban Development (HUD). A life-cycle cost analysis from the homeowner's perspective was used to establish parameters for a least-cost home in a large number of cities. Economic, financial, and energy-efficiency measures for the life-cycle cost analysis were selected and documented. The resulting energy-efficiency levels were aggregated to zones that were expressed as a maximum overall home U-value (U0) requirement for the building envelope. The proposed revised standard's costs, benefits, and net value to the consumer were quantified.  This analysis updates a similar effort completed in 1992, which was the basis for the existing HUD code U0 requirement.  Updated U0s for manufactured homes are recommended.
