Taking the Air (Barrier) Out of ASHRAE 90.1 – With a Taste of MN Hotdish

The 2021 International Energy Conservation Code (IECC) adopted ASHRAE Standard 90.1-2019, which includes mandatory requirements for air barriers. This session will explore key topics such as Whole-Building Air Leakage and Continuous Air Barrier Design and Installation—both essential components of the compliance path. Our speaker, Pam Jergenson from Minnesota, will guide attendees on the pathway through the air barrier provisions in ASHRAE 90.1-2019 and highlight Minnesota-specific amendments that may resemble your local code. And since it’s a Lunch and Learn, we’ll serve up those code insights with a side of cozy Minnesota hotdish flavor!

Learning Objectives:

1. Know the starting point and path through ASHRAE Standard 90.1-2019 for air barrier materials and systems during the design and construction phases.
2. Understand specific Minnesota amendments to the air barrier part of the standard, their impact, and what could be in your code.
3. Know Section 5, Building Envelope; specifically, the Compliance Paths, Mandatory Provisions, Submittals, Products, and Inspection and Verification for air barriers.
4. Analyze 5.4.3.1.1, Whole-Building Air Leakage, describing the Exceptions and the Minnesota amendment to the Exceptions that may be similar to your region.
5. Apply 5.4.3.1.2, Continuous Air Barrier Design and Installation requirements to the design and construction phases.
