ANNEX VU.K. Weighting of technical domains
1.Each technical domain is weighted for each of the impact criterion and the weighting factors characterise the influence of the technical domain on the impact criterion.U.K.
2.Technical domains’ weighting factors are expressed as a percentage, and for each impact criterion, the sum of the weighting factors of the technical domains equals to 100 %.U.K.
3.The standard approach to allocate weighting factors to the technical domains is based on:U.K.
(a)
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;
(b)
for all other cases: weighting factors that are either fixed or equally distributed.
