In Vermont’s commercial construction industry, the word is well out there by now that the 2020 Commercial Building Energy Standards mandate building air barriers receive special attention, to some degree – either at post-envelope construction by way of a blower door test, or throughout the construction phase by way of commissioning (no blower door test). I’ve discussed portions of this in the past when it was relatively new. The 2021 IECC release now also mandates either air barrier commissioning or blower door testing. It will be some time before states begin to adopt this version of the code, but it is only a matter of time. So, I thought it a good idea to get out ahead and discuss why I think we, as an industry, should be considering the two of these options in harmony, rather than separately.

Lately, I’ve been asking myself, “What can be done better on the building enclosure side?” I think one of those things is employing installation checklists.
