Installing High-Performance Windows

摘要

The guiding principle of a Passive House is that its primary source of heat is the sun. Not only do you have to locate and size windows and doors to take advantage of that sunlight, but they have to be high-quality units capable of retaining that energy for times when the sun isn't shining. That's a tall order when you have 24 windows and three entry doors and your goal is a finished house with an air-leakage area that's roughly the size of an index card.
