Mark Butler posted this article by Rick Karg (Residential Energy Dynamics) in the RESNET group on LinkedIn -- I thought it might be helpful to spread it around a little further.
Here's the article:
ANSI 380 -2016
Rick notes that there are some changes and improvements -- most sound positive, clarification and simplification of procedures and protocols. There's a nice set of definitions to take the guesswork out of your day.
Also a recommendation to take the standard with you in your toolkit. When I was doing blower door tests as my main gig, I had the Canadian version of this with me. Helpful for those goofy challenges.
Hope this helps!
