German Building Energy Act Replaces EEG, EnEV and EEWärmeG

After a long coordination phase, the German Building Energy Act (Gebäudeenergiegesetz, GEG) is to come into force in the second half of 2020. The government draft of 23 October 2019, on which the Act is based, largely takes over the requirements of the predecessors, EnEV as of 2016 and the EEWärmeG, and defines the energy standard according to EnEV 2016 to be the lowest-energy building according to the EU building directive. Specific changes relate, for example, to a lower limit for primary energy factors, a ban on oil-fired heating systems from 2026 and the obligation to consult with energy consulting services, but also measures to facilitate the situation to facilitations such as the improvement of PV systems. Further adjustments to the content of the energy standard are possible in the ongoing legislative process.  The energy standard is to be reviewed and further developed in 2023.

New Guidelines for Road Noise Protection – RLS-19

Almost 30 years after the introduction of the “Guidelines for Road Noise Protection “, 1990 edition (RLS-90), a new edition, RLS-19, has now been published. This new edition takes into account the changes in vehicle technology. The old edition was still based on investigations of vehicle fleets in the 1970s. In addition, GEStrO-92 has been replaced by the “Technical Test Specification for the Determination of Correction Values of the Noise Emission of Road Surface Layers”, 2019 edition (TP KoSD-19). This introduces a new procedure for determining noise reduction values for innovative road surfaces which are then taken into account in the calculations.


Specifically, RLS-19 introduces the new road surface correction value DSD. This involves making a more differentiated consideration than before, with a distinction between passenger cars and trucks as well as between different speeds. In addition, trucks are divided into two vehicle groups, with and without trailers, with the share of vehicles being included in the calculations separately. The new directive also includes further adjustments regarding the speed of trucks on motorways and factors in the longitudinal inclination of the road.


The new guidelines will only be introduced when the 16th BImSchV has been amended, which is still pending.
