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.

A research project in the State of Arkansas identified opportunities to reduce homeowner utility bills in residential single-family new construction by increasing compliance with the state energy code. The study was initiated in May 2015 and continued through October 2015. During this period, research teams visited 226 homes during various stages of construction, resulting in a substantial data set based on observations made directly in the field. Analysis of the data has led to a better understanding of the energy features present in homes, and indicates over $300,000 in potential annual savings to Arkansas homeowners that could result from increased code compliance.

The U.S. Department of Energy (DOE) recognizes the enormous potential that exists for improving the energy efficiency, safety and comfort of homes. The 2012 International Energy Conservation Code (IECC) sets the bar for energy efficiency, and air sealing requirements are one of the key provisions.

This guide is a resource for understanding the air leakage requirements in the 2012 IECC and suggestions on how these measures can be met. It also provides information from Building America’s Air Sealing Guide, best Practices and case studies on homes that are currently meeting the provisions. The 2012 IECC and a few International Residential Code requirements are referenced throughout the guide.

The 2009 International Residential Code and International Energy Conservation Code do not permit trade-offs for installing high-efficiency heating, ventilation, and air conditioning equipment—installing a 90%+ furnace as a trade-off for 2" x 4" stud walls with R-13 insulation. The more permanent building insulation and sealing features now take precedence. However, there still remain optional strategies allowing 2" x 4" exterior stud walls.

Conformity assessment is a term used to describe the processes followed to demonstrate that a product, service, management system, or body meets specified requirements, such as standards, codes, laws, regulations, or other criteria. With respect to energy codes, conformity assessment includes all activities and tasks undertaken by any number of entities to ensure that the provisions of an adopted energy code are achieved at a designated point in time. This report identifies and discusses conformity assessment activities and provides guidance for developing new or adjusting existing ways of verifying compliance. In addition, this report looks at different ways to ensure that the energy efficiency goals of an adopted code or standard are achieved.

Converting a basement to conditioned space increases the living space of a house. As with most construction activities, the conversion or remodeling must be done in compliance with construction codes in force at the time the remodel permit is issued. Compliance shall be demonstrated by meeting the requirements of the 2009 International Energy Conservation Code.

Many studies have shown that visual inspection of duct seals in residences is not enough. Code now requires a pressure test. Pressure testing ducts as required by the 2009 International Energy Conservation Code is far superior to visual inspection and will definitively confirm that duct leakage is kept to a low level.

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.

Ensuring compliance with HVAC control requirements is difficult, as controls can be difficult to identify on plans or in the building, yet it is a crucial task. HVAC controls are a key driver of building performance and without compliance and enforcement activities, the code requirements may be ignored, overlooked, or misunderstood.

This guide provides an aid that will make it easier to apply the heating, ventilation, and air conditioning (HVAC) control requirements found in building energy codes and addresses requirements defined by 2009 and 2012 editions of the International Energy Conservation Code (IECC) and ASHRAE Standard 90.1-2007 and ASHRAE Standard 90.1-2010.
