Thus, we refer to IECC 2018/ASHRAE 90.1-2016 as the “newest” code cycle. While that isn’t quite ready for publishing yet, the 2016 Standard is out and ready for adoption. In January, I attended the ASHRAE meeting in Atlanta, where we worked on the final stages of the 2019 ASHRAE 90.1 Standard. The Newest Code Cycle: IECC 2018/ASHRAE 90.1-2016 You can think of this as a guideline to help determine which adoptions have been made in your state. The chart above, which is a comprehensive list of codes adoptions in each state, is current as of December 2018. The resources we use for state code changes include the Department of Energy (DOE), the Building Codes Assistance Project (BCAP), and the International Code Council (ICC). This article focuses on changes to roof and wall assembly code requirements, but remember that there are updates to other elements of the building envelope that you should also be aware of. There are 3 major components of an energy code:Īdditionally, there are many elements within the building envelope subject to energy code regulations: This means that IECC is ultimately a more stringent code than the ASHRAE Standard.
#Ashrae 90.1 2013 update#
This metal building industry update is designed to cover the most recent building envelope changes within the latest code cycles and the specific insulation system innovations that meet the latest codes.

Additionally, newer energy codes contain higher performance expectations, which not only require more insulation, but also call for more advanced systems, such as air barrier systems, liner systems, and more. An entirely new vocabulary is used when talking about metal buildings: “conditioned space,” “climate zones,” “air barriers,”-30 years ago this was all unheard of. Increasingly stringent energy codes have propelled the industry toward more sustainable construction and innovation that we wouldn’t have imagined a few decades ago. The metal building industry has witnessed a tremendous shift over the last several years.
