To achieve Passive House certification, a passive house must provide consistent, comfortable temperatures throughout the year, without using conventional heating or air conditioning systems. Using the existing temperature provided via solar radiation through the windows as well as the heat from appliances and inhabitants is sufficient.

The required heating energy for a passive house is only 10% of that needed for a conventional house. These extraordinary savings are rooted in the two basic principles of minimising thermal loss and optimising thermal gain.
