     * Existing buildings in Germany use an average of 160 kWh of fuel (oil or gas) for heating alone – see statistics from the companies in charge of heating bills. For calculation purposes: 1 litre of fuel oil or 1 cubic metre of natural gas each have a calorific value of approximately 10 kWh.     * Existing buildings in Germany use an average of 160 kWh of fuel (oil or gas) for heating alone – see statistics from the companies in charge of heating bills.

     * The data recorded in the Passive House in Darmstadt Kranichstein,​ on the other hand, shows a stable consumption of as little as 9.2 kWh per square metre of living space.     * The data recorded in the Passive House in Darmstadt Kranichstein,​ on the other hand, shows a stable consumption of as little as 9.2 kWh per square metre of living space.
 This means: Passive Houses require less than 10% of the energy used by typical central European buildings. In fact, the amount of heat required is negligibly small – so small that such a house could be heated by a few candles.\\ This means: Passive Houses require less than 10% of the energy used by typical central European buildings.
