DGNB discussion proposal GEG 2050

The contents of a future German Building Energy Law in just three pages

To limit the impact of man-made climate change to an "acceptable level", our society needs to drastically reduce its greenhouse gas emissions in the coming years starting today. With global CO2 emissions still on the increase and CO2 concentration expected to reach critical levels within 20 years (according to the latest calculations), the immediate responsibility is on politicians, businesses, public institutions, non-governmental organisations, research and education institutions to draw on every ounce of their potential. This calls for new legislative guidelines for the building sector, based on the climate protection goals.

In 2017, the Energy Saving Law (EnEG), the Energy Saving Ordinance (EnEV) and the Renewable Energies Heat Law (EEWärmeG) were merged to produce a draft version of the new "Building Energy Law" (GEG). However, the DGNB believes that the answer is not to build on the existing systems and the same mentality. Instead, we believe that this is our opportunity to apply what we have learned in recent years in order to determine a new, target-oriented approach. Our concern is that we will lose yet more valuable time if the current GEG draft forms the basis for further debates, since a 150-page EnEV amendment that is, in our opinion, incorrect, convoluted and incomprehensible and therefore is missing the mark. The long service life span of our buildings means that we need future-proof laws today, which will continue to apply until 2050. This can be achieved, which is why the DGNB has produced this three-page GEG proposal that provides an effective focus on the climate protection targets. It was important to us to present this in a clear and target-oriented manner from the outset. This draft must, of course, be subsequently assessed with regard to the various stakeholders involved, the finer scientific points and the legal framework conditions, and reformulated as necessary.

It is important that we shift to a goaloriented thinking, and formulate and discuss this clearly. Only then will it be possible to unite all the relevant players in one common objective. To discuss the technical details at this early stage would serve only to distract from the actual goal. Our proposal for a "Building Emissions Law 2050" (GEG 2050) incorporates the following four core requirements:

  1. The target figure must be the CO2 emissions and not the primary energy demand of our buildings.
  2. The evaluation must be completed using absolute CO2 emissions limit values and not by means of theoretical reference buildings.
  3. If target values are not met, a CO2 fee will apply.
  4. All evaluations, specifications and control mechanisms must be based on data from actual consumption measurements.
