Do you not feel that door blower tests on small, airtight domestic
buildings, as required for passivhaus certification, are not
reasonably accurate?

I quite agree that for large or very leaky buildings there is a real
problem, but I don't agree that there is no such thing as
sufficiently-accurate testing, and the passivehaus people are nothing
if not careful and rigorous about the science.
