| * 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.

| 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.
