Flexibility: National Choice

Flexibility: national choices possible in methodology, input data and references to other standards

Clearly identified options and national data remain necessary due to differences in climate, culture and building tradition, building typologies, policy and legal frameworks (including the type and level of quality control and enforcement). This is foreseen in the set of EPB standards via options that can be chosen according to a specific template: the “Annex A/Annex B approach”; see explanation on national annexes
