Energy Saving Ordinance 2014: What’s next with the amendment?
Federal Government: As the responsible federal ministries (Construction and Economy) report in their joint press release, the federal government has today’s cabinet meeting approved all requirements of the Bundesrat and passed the amendment to the Energy Saving Ordinance.
Promulgation: The next step is the editorial preparation of the text for the Energy Saving Ordinance amendment for the promulgation of the amendment ordinance to the Energy Saving Ordinance (short: Energy Saving Ordinance 2014) in the Federal Law Gazette of the Bundesanzeiger Verlag in Cologne. Accordingly, the amendment to the Energy Saving Ordinance could actually still be promulgated in the Federal Law Gazette this year.
Entry into force: According to the report from the responsible federal ministries, the Energy Saving Ordinance 2014 is most likely to apply from early summer 2014, i.e. 6 months after its promulgation at the end of this year in the Federal Law Gazette. As we know from previous versions of the Energy Saving Ordinance, there are also special transitional periods, about which we will inform you.
so, we will probably have to wait and see how the transitional periods will be.
