jeffwTIL about “passive houses,” building that are airtight and require barely any energy to heat or cool
mindKitchens and bathrooms need proper ventilation.
Also, how do you maintain proper levels oxygen and carbon dioxide in an airtight house?
CarbonIceDragonReading through the article suggests that they aren’t completely airtight, rather that the air comes in and out through mostly only through specific paths, with some sort of system that exchanges the heat with air leaving the house, so that the heat (or lack of heat if keeping the building cold) does not leak out much when the air circulates through.
