Adoption and enforcement of any new code often occurs into its second or third year of publication, depending on the jurisdiction. A Climate Zone Map can be found in the 2012 International Energy Conservation Code (IECC), funded by the U.S. Department of Energy- Energy Efficiency and Renewable Energy. Climate Zones is used by the International Residential Code (IRC) and Model Energy Code. Lighting Systems C406.4 –On-site Renewable Energy 2012 IECC –Option: Prescriptive. Floor R-Value. The 2018 IECC requires air leakage requirements of windows, doors and skylights to be in accordance with NAFS-17 or NFRC 400-17; and curtainwall, storefront, and commercial doors must be in accordance with ASTM E283-04 (2012). On October 1, 2018, Pennsylvania changed from IECC 2009/ASHRAE 90.1-2007 to the IECC 2015/ASHRAE 90.1 2013 code. 2.

Refer to the requirements for each building envelope area, based on your project’s Climate Zone IECC 2015 Requirements by Climate Zone 3. 4. C402.2.7 Airspaces o Thermal Properties. More than 2.5 million Coloradans, or 44% of the state's population, live in a jurisdiction with the newest and most efficient energy code—the 2018 IECC. While you complain that the climate zone map doesn't make fine distinctions between climate zones, that was the deliberate intent. About 44 jurisdictions have adopted it so far, with another 21 in the process or under consideration. Current News: In February 2019 Utah lawmakers adopted the 2018 I-Codes (except the IRC and residential provisions of the IECC, residential remains a "hybrid" 2009/2012/2015 version - see House Bill 218 for details). Determine your climate zone. If you're in one of the 10% of U.S. counties that fall into two separate climate zones depending on which code you're following, you may notice that R-value requirements between the two may differ, especially since IECC 2018 is based on older ASHRAE data. Surprisingly, prior to 2004 there was no universal climate zone map for the U.S. for use with building codes. 2018 IECC Commercial Significant Changes Ken Baker – (thanks to Eric Makela and CADMUS) 2 Climate Zone Modifications (ASHRAE) 2.

At that time, ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) used 38 different climate groupings, while the IECC used 33 different zones based on county boundaries. Many requirements are contingent on the climate zone. From the time the 2009 edition of the IECC was published until the most current published 2015 version, the IECC building code has increased R-value requirements year over year by 30%, on average.
