Energy efficiency of buildings - Calculation of the net, final and primary energy demand for heating, cooling, ventilation, domestic hot water and lighting - Supplement 1: Balancing of demand and consumption
This supplement includes two important application-related aspects: Balancing of demand and consumption The supplement is intended to assist users wishing to change the energy requirement values computed in accordance with Parts 1 to 10 of the standard in order to balance demand and consumption. It contains recommendations on how to check the input data used to calculate balances. Depending on the way the input data affects the final result it can be tested in a particular order and modified if necessary. Realistic balance The method described in this supplement can still be used if no information on energy use is available (e. g. in new buildings) or the available data cannot be used as it includes unknown percentages of process energies. The method described examines the input data depending on its effect on the final balance so that it can be modified if necessary in order to achieve as objective an estimate as possible of the building, the technology and its users.
