Remember that there are three major components of an energy code:Īdditionally, there are many elements within the building envelope subject to energy code regulations: The IECC code sometimes increases efficiencies in certain areas, which means that, in some cases, the IECC code can be more stringent than the ASHRAE Standard. IECC references the latest ASHRAE Standard, plus any addendums and new data.For example, IECC 2012 references ASHRAE 90.1-2010. IECC follows behind ASHRAE 90.1 by two years.ASHRAE 90.1 and IECC have different three-year cycles.IECC is a model energy code that references the ASHRAE 90.1 Standard. If you feel comfortable with this information and don’t need the primer, skip down to the section titled, “ Code Adoption by State as of December 2018”.įirst, ASHRAE 90.1 is a minimum Standard of energy efficiency, not a code agency.
#Nj ashrae 90.1 2016 update
The Difference Between ASHRAE and IECCĪny thorough commercial energy code update wouldn’t be complete without a review of the basics. 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 daylighting. An entirely new vocabulary is used when talking about metal buildings: “Conditioned Space”, “climate zones”, “ air barriers” 30 years ago this was all Greek.
Increasingly stringent energy codes have propelled the industry toward more sustainable construction and innovation that we wouldn’t have imagined a few decades ago. With plenty of new changes on the horizon, now is as good a time as any for me to provide a comprehensive update on the current state of the codes landscape, as well as what you can expect for the rest of the year.īefore I get into specifics, take a step back and think about it: The metal building industry has witnessed a tremendous shift over the last several years. Though it’s not yet ready for publishing, there will be quite a few changes from the current code cycle to the 2019 Standard. Earlier this year I attended the ASHRAE meetings in Atlanta, where we worked on the final stages of the 2019 ASHRAE 90.1 Standard.
