The energy demand required for heating the hot water is not included in this value. Depending on user behaviour, the average annual energy consumption for hot water is between 550-900 kWh per person. This entry is required in order to determine the output or energy demand of the building/m2, similar to energy certificates. If the hot water was also heated with the specified energy source, the energy demand required for this is included in this value. Depending on user behaviour, the average annual energy consumption for hot water is between 550-900 kWh per person.heated living area (m2):
