Developing a method for comparing energy performance requirement levels among Europe

Share this Post:
Within the EU ASIEPI project ( a methodology was developed to make possible a comparison of energy performance requirement levels among Member States of the EU. An unexpected finding has been that far from all the EU countries consider all energy uses in their energy performance calculation method required by the EPBD (Energy Performance of Buildings Directive). The energy use for fans, domestic hot water and cooling are among the energy uses which are not taken into account by various countries. This largely complicates the comparison over Europe. What also complicates the comparison is that sets of energy saving measures are not equally relevant in all climates in Europe. The paper summarises the difficulties in comparing the national regulations and presents options for the comparison.
