A National Annex is filled in and published by a National Standards Body (NSB), as annex to the national implementation of the EPB standard. The NSB can choose to publish this stapled to the standard, or as separate document(s). Consequently, it is publicly available, but it may not be available for free.
A National Datasheet can be a separate document referred to by the building regulations, or an integral part of the building regulation implementing the EPBD. One may therefore expect it to be publicly and freely available.
Development of a National Annex or National datasheet is a critical process that may take some time. Although countries are working on it, at the beginning of 2021 there were only a few published.
A National Annex or National Datasheet to describe the national method in terms of the Annexes A of the five so called overarching EPB standards (acc. to EPBD:2018, Annex 1) may not be publicly available.
