The 2006 International Energy Conservation Code (IECC) envelope requirements are not coupled to the home''s glazing area percentage. A home with modest glazing area, say 13% of
floor area, will likely require a more efficient envelope for 2006 IECC compliance. Conversely, a home with larger glazing area, say 20% of floor area, may achieve 2006 IECC compliance with less insulation.

The 2006 IECC also implemented a new climate zone system. The system introduced more homogeneity across climates, resulting in less variation in the envelope requirements from location to location. Therefore, some locations have slightly different (higher or lower) efficiency requirements under the 2006 IECC than under the previous codes.

AreaCalc is a tool to simplify the process of calculating the building areas needed to demonstrate energy code compliance. A spreadsheet-like interface is used to calculate window, door, skylight, roof, wall, and floor areas. These areas can then be transferred directly into REScheck™ where the code compliance results for those assemblies can be displayed.

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.

Many homes are being constructed with unfinished basements to reduce initial costs. In most cases, the homeowner eventually finishes the basement for additional living space by installing basement wall insulation. Because most basements are eventually occupied, the advantages and disadvantages of conditioning the basement should be thoroughly reviewed prior to permitting and construction.

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.

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.

Adequate attic ventilation is a long-standing requirement in building codes. However, conditioned, unvented attics have the potential to reduce residential energy needs and are allowed by code under certain conditions. Such assemblies are sometimes called cathedralized attics because, as with cathedral ceilings, the insulation is in the rafters and/or roof deck.

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.

Ducts and air handlers should be placed in conditioned spaces when possible. Ducts typically lose substantial amounts of energy from both conduction and leakage; keeping them in a conditioned space minimizes the impact of these losses. Ducts inside a conditioned space must be properly sealed, but are not required to be insulated.

The prescriptive envelope component criteria (Section 502.2.5) in the 2003 International Energy Conservation Code (IECC) is an alternative compliance path for sunrooms and additions to existing residential buildings and structures.

There are three approaches to make an addition comply with the energy code:

  • The addition as defined above meets all code requirements. This approach does not require that the original portion of the building meet code requirements.
  • If the building combined with the addition complies with the code, the addition will also comply, regardless of whether the addition complies alone. For example, a sunroom that does not comply with the code is added to a house. If the entire house (with the sunroom) complies, the addition also complies.
  • In the 2000 and 2003 International Energy Conservation Code, additions less than 500ft2 (46.5m2) of conditioned floor area may meet the prescriptive envelope requirements in the table. To use the table, the total area of windows, doors, and skylights cannot exceed 40% of the gross wall and roof area of the addition.
