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.

The Advanced Energy Design Guides (AEDGs) are a series of publications designed to provide recommendations for achieving energy savings over the minimum code requirements of ASHRAE Standard 90.1. This is the first step in the process toward achieving a net zero energy building—defined as a building that, on an annual basis, draws equal or less energy from outside resources than it provides using on-site, renewable energy sources. The guides have been developed in coordination with the following organizations: the American Institute of Architects, the Illuminating Engineering Society of North America, the U.S. Green Building Council, and the U.S. Department of Energy. The New Building Institute participated in the development of the initial guide.More information on the AEDGs may be found on the Building Technologies Office Commercial Buildings website....

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.

Duct insulation and sealing, especially insulated supply ducts delivering conditioned air within a building, save energy. The intent of energy efficiency codes, as related to duct insulation and sealing, is to keep mechanically warmed or cooled air as close to a constant, desired temperature as possible and prevent the conditioned air from escaping the duct system while it is being moved to spaces where it is needed. If reduced heat transfer through insulated ducts is accounted for in the heating, ventilating, and air conditioning (HVAC) load calculations, it may even be possible to reduce the size of HVAC equipment.

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.

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.

This report assessed commercial building practices to the 2003 International Code Council International Energy Conservation Code (IECC). Plan review and field inspection of 55 new construction commercial buildings determined if the plans complied with the IECC, and if the building was built to the plans and code. Because an energy code had not previously been enforced, personnel were trained to conduct the onsite inspections and collect data on "typical" commercial construction. Compliance issues were identified and documented.

Insulation installed in a suspended ceiling does not meet the infiltration requirements of the International Energy Conservation Code. When the insulation is on the suspended ceiling, the ceiling is defined as part of the building envelope. This requires that it be air-sealed like any other envelope component.

The effectiveness of insulation is measured by its R-value - the resistance to heat flow. The higher the R-value, the greater the insulating value. The recommended amount of insulation depends on the building design, climate, price of energy, and cost of materials and labor. Choose insulation materials based on the installed cost per R-value per square foot.

In supporting state energy code compliance evaluations, the U.S. Department of Energy's Building Energy Codes Program (BECP) has developed residential data collection checklists. The checklists are available for use as paper checklists or electronic Microsoft® Word® forms.The BECP also developed an online tool, the Checklist Score + Store. While overall compliance can be determined manually for individual buildings and groups of renovations, this tool provides automated building scores and state-wide consolidation of data. Individual building scores will remain confidential (available only to the state and their contractors), but storing data nationally will shed valuable light on nationwide compliance, as well as changes in compliance over time.Guidelines for using the following checklists to evaluate state energy code compliance can be found in...
