Building Science: Build Very High Levels Of Energy Performance Into New Homes
Building Science article describes, using this Westford House as an example, how to build very high levels of energy performance into new homes. Use lots of insulation, airtight construction, controlled ventilation, and not a lot of glass. Use real good glass whenever you use glass, use real good appliances, use real good lighting, and after you have done all of this use real good equipment. The real good equipment is now pretty small because you have done the other stuff. And then stop.

Building Science: Just Right & Airtight
Building Science says folks are building houses and retrofitting existing houses with increased airtightness, and this is great. They use a blower door to help measure leakage, and this is also great. But then they think that a blower door actually is a precise measuring tool for how air will leak across the building during service. Wrong. Even more serious an issue is to then take the leap that using a wrong assumption about the results of an approximate measurement can be used to decide that mechanical ventilation is not needed. Bad, very bad, and potentially deadly.
