Questions concerning the interpretation of the paragraphs of the Energy Saving Ordinance 2009
In accordance with the constitution, the federal states are responsible for the legal enforcement of the legislation on energy saving. In the course of the implementation of the Energy Saving Ordinance (EnEV) questions arise, especially in the beginning. They are not always clearly answerable from the legal text alone or from standards referred to by the ordinance and allow various interpretations.
To allow in this context an implementation of the Energy Saving Ordinance as consistent as possible, the Expert Commission on Construction Technique ("Fachkommission Bautechnik") of the Conference of Ministers of Construction and Housing ("Bauministerkonferenz") decided to install a working group. This working group shall answer incoming questions of common interest. The draft answers of the working group are discussed by the Expert Commission.
The working group was installed with the participation of representatives of the Ministry of Transportation, Building and Urban Development, the Federal Office for Building and Regional Planning, the upper authorities in charge of building codes of Bavaria, Baden-Württemberg, Berlin, Brandenburg, Bremen, Hamburg and North Rhine-Westphalia as well as the Institut für Bautechnik (DIBt).
The questions and answers as they are displayed here were adopted at the respectively stated date and apply to the version "EnEV 2009".
