What about air tightness?

There is no specific target for airtightness but it is explicitly required to prevent uncontrolled air leakage. It’s not clear what this means but the key is to attempt to form a continuous air barrier around all details and around the whole building. It really doesn’t take a lot of cost or time to make a pretty air tight building. Blower door testing after construction helps diagnose gaps and educate installers.
