Energy Vanguard has a huge amount of excellent building science and especially air tightness info. Sadly it is US based which means annoying imperial units, and often discussions on US regulations and standards. Some here might never the less appreciate the often technical in depth discussions. [Emphasis added]
So I’ll say it again: It’s time for the US to join the rest of the world! Using a system of units that seems easy only because it’s the one we know and having to convert to a more sensible system when we want to talk to the rest of the world is nuts.
Hey, if I can tilt at the HVAC windmill, why wouldn’t I go after this one, too?!
