With the rapid evolution of building codes and regulations, it can be a challenge to stay up to date. The rate of change is faster than ever, and codes themselves are becoming more and more complex. This is especially true with building code insulation requirements, and other building envelope requirements.
Complying with building code requirements
Compliance can vary from jurisdiction to jurisdiction. To truly understand which standards to follow, you need to understand all details applicable in your local area. However, there is significant commonality across states that have adopted versions of the International Energy Conservation Code (IECC)—the primary model residential building code adopted by states and municipalities across the country.
Energy code compliance guides
NAIMA has developed a series of brief building envelope compliance guides, for each state, for both the 2009 and 2012 versions of the IECC, which can be found here. These outline building code insulation requirements, as well as other requirements for the building envelope.
Staying on top of code changes
The best resource for the latest info on the status of code changes and adoption across the country is the Building Codes Assistance Project (BCAP). Each month, they update their “Code Adoption Status Map” for both residential and commercial buildings, shown below. Visit their site to click on a state and get additional information on code adoption activity, as well as links to code details. Their detailed info on each state can actually take you to the exact code language in effect. Signing up for BCAP’s monthly newsletter is another good way to have the latest info on code developments delivered right to your inbox on a regular basis.
