Division 3 The standard approach to allocate weighting factors to the technical domains is based on:

The climatic zone's energy balance for the weighting factors of ‘heating’, ‘cooling’, ‘domestic hot water’, ‘ventilation’, ‘lighting’, and ‘electricity’ technical domains along the ‘energy efficiency’, ‘maintenance and prediction’ and ‘energy flexibility and storage’ impact criteria;

for all other cases: weighting factors that are either fixed or equally distributed.
