Since the latest posts are previous to the new Energy Efficiency Directive, which rephrased the exemplary role of the public sector, I hope you find this post relevant to open new discussions in this community. In short, the new directive establishes the "exemplary role of public bodies' buildings" in terms of more restrictive requirements on certification, and NZEB standards than those applied to "non-public buildings". It also includes a mandatory rate of refurbishment (3%) on certain public buildings. Overlaps with certification, green procurement and, especially with the concept of demonstration building, together with a mild policy formulation could be jeopardizing the conceptualisation of this, otherwise, very interesting policy approach. This could result in delays in its implementation. I would be interested in your insights on what defines this concept (a policy instrument in itself?), or: what should be expected of future developments of the Directive. Would you recommend any "exemplary" bodies or buildings (irrespective of their obligation)?
