Passive Houses are buildings that need very little energy to achieve a comfortable temperature without the help of either a conventional heating or air conditioning system. An extremely well insulated building envelope as well as triple glazed windows ¹⁾ and insulated frames keep the desired warmth in and undesirable heat out. This means that the floor and all interior walls stay at the same pleasant temperature - year round.
