Air tightness has to be countered by controlled ventilation, whether passive or mechanical which can lead to good overall results, & i’m lead to believe a more healthy living environment.
The air pressure process is not great, but I believe that big difference is the fear of the risk of a failed test. Yes there have been instances of over zealous use of sealant & tape early on but as an industry, we are getting there. There of course will always be the some fails.
The industries next big challenge is thermal bridging, lighting & hot water. Chasing U values once you get below 0.1 starts to become uneconomic
