 Yet, a Passive House is more than just a low-energy building.\\
 \\
-  * Passive House buildings allow for heating and cooling related energy savings of up to 90% compared with typical building stock and over 75% compared with average new builds. In terms of heating oil, Passive House buildings use less than 1.5 litres per square meter of living space per year – far less than typical low-energy buildings. Similar energy savings have been demonstrated in warm climates where buildings require more energy for cooling than for heating.

A small heat pump is a much better and cheaper solution, a ≈2.5 kW<suv>th</sub> split unit will do.)). Similar energy savings have been demonstrated in warm climates where buildings require more energy for cooling than for heating.
   * Passive House buildings are also praised for their high level of comfort. They use **energy sources inside the building** such as the body heat from the residents or solar heat entering the building – making heating a lot easier.
