This document is a list of Alaska-specific amendments to the 2009 International Energy Conservation Code, adopted by the Alaska Housing Finance Corporation (AHFC) on March 9, 2011. It is meant to be read in conjunction with the 2009 IECC and ASHRAE Standard 62.2-2010 which may be purchased at local bookstores or online. These amendments comprise both the residential and commercial Building Energy Efficiency Standards (BEES) for AHFC-funded residential mortgage loans and energy rebates, and energy retrofits of public buildings. These amendments supplant the BEES amendments to the 2006 IECC for residential projects as adopted on June 17, 2009, and include the amendments previously made to the 2009 IECC known as the “Commercial BEES.”

This study was undertaken for the Arizona Department of Commerce, who requested the U.S. Department of Energy (DOE) provide technical assistance with regard to identifying the major differences in the model energy codes as they might be applied to various locations in Arizona. This study focuses upon the requirements for commercial (non-residential) buildings in these codes. In both codes, “commercial” buildings include high-rise multi-family buildings as well as traditional “commercial” occupancies such as offices, retail buildings, and assembly buildings.

This study was commissioned by the Florida Department of Community Affair’s Codes & Standards Section to determine the impacts of Florida’s Energy Code over time and recommend possible changes that would increase residential efficiency. It examines each of the 15 residential energy code cycles that have occurred during the 30-year period from 1979 to 2009, and determines the relative change in energy code efficiency and its impact on energy use and energy cost throughout the period. The study has been revised to include Florida’s 2009 supplement to its 2007 energy code to determine how its requirements compare with the requirements of Section 405 of the 2009 International Energy Conservation Code. Florida’s energy code compliance software, EnergyGauge® USA, is used to conduct annual, hourly simulations and analysis of 180 different home configurations. These results are combined with Florida’s historical energy cost data and new home...

This study includes the impacts of adopting only the building envelope and lighting requirements of ASHRAE Standard 90.1-1999 and applying it only to new commercial construction. This report builds on a previous study that uses prototypical office, retail, and education buildings to estimate life-cycle cost savings estimates per square foot. Office, retail, and education buildings made up over 60% of the total value of new commercial construction in Illinois in 1997.

This report is an update of a previous report, Statewide Savings Projections from the Adoption of a Commercial Building Energy Code in Illinois, completed in September 2002. This updated version incorporates the most recent—as of the writing of this report—gas and electric rates into the analysis.The results of this analysis suggest that adopting and enforcing a commercial building energy code throughout the state of Illinois could produce substantial energy and cost savings, while reducing emissions of greenhouse gases.

This nationwide analysis of commercial energy code compares ASHRAE Standard 90.1-2007 with the commercial code in each state as of June 2009. The results are provided in chapters specific to each state.States with unique energy codes were not included in the analysis because the codes in these states would be difficult to appropriately compare to ASHRAE Standard 90.1 and most of these states have energy offices that routinely assess their codes against the model codes. In states with codes prior to and including the 2000 IECC or Standard 90.1-1999, those states with no statewide energy code, and home rule states which did not specifically request that another code be used, Standard 90.1-1999 was used as the baseline for comparison.Three DOE Benchmark buildings were used for the simulation used in this analysis: a medium office building (53,600 ft2), a mid-rise apartment building (33,700 ft2), and a non-refrigerated warehouse (49,500 ft2)— representing ASHRAE Standard 90.1 non-...

This analysis of residential energy code compares the requirements of the 2009 International Energy Conservation Code (IECC) with the residential code—or typical construction practice in the absence of a code—in most states as of June 2009. The results, which include estimated typical energy savings of updating each state’s code to the 2009 IECC, are provided in chapters specific to each state.Several states have either not adopted a mandatory energy code or developed their own codes which have minimal or no connection to the IECC. The latter—including California, Florida, Oregon, and Washington— were not included in this analysis because the codes in these states would be difficult to appropriately compare to the 2009 IECC and most of these states have energy offices that have already assessed the IECC on their own.

In November 1999, the Pennsylvania Legislature passed ACT 45, known as the Uniform Construction Code, into law mandating a statewide building code across Pennsylvania. Act 45 requires the Pennsylvania Department of Labor and Industry (DLI) to promulgate regulations to implement the requirements of the legislation and, in addition, to consider the development of alternative prescriptive methods for energy conservation that account for the various climatic regions within the Commonwealth. In deriving these energy standards, the DLI was to seek to balance energy savings with initial construction costs.
