Regulatory framework for energy efficiency

The German Energy Saving Ordinance (EnEV) introduces mandatory standards for energy-efficient building and refurbishment. It defines the requirements for a building’s energy efficiency 

and for the issue and use of the energy performance certificate.

German Energy Saving Ordinance (EnEV)

Energy-efficient building and refurbishment the right way

Compulsory regulations are needed to ensure the success of the energy transition. Here, dena advocates a convenient and uniform regulatory framework that does not use compulsion.

The German Energy Saving Ordinance (EnEV) is a central instrument within German energy and climate protection policies. Its purpose is to ensure that the targets of the Federal Government’s energy policies are achieved – in particular a largely climate neutral inventory of existing buildings by 2050 and around 60 percent savings in final energy consumption through efficiency measures on the building envelope and construction technology compared with 2010. The ordinance defines structural and heating system standards for buildings and specifies the energy efficiency for new builds and the refurbishment of existing buildings. EnEV is based on the Energy Saving Act (EnEG); its effectiveness is further supported by other standards and laws such as the Renewable Energies Heat Act (EEWärmeG).

Simple and uniform regulatory framework

The German Energy Saving Ordinance provides a reliable norm-based framework for building owners and planners of new builds. The German Energy Saving Ordinance trusts largely in voluntary commitments for existing buildings. An important fact here – as outlined in NAPE – is to simplify the regulatory requirements and, at the same time, to provide more attractive funding programmes.

dena welcomes the creation of plannable and reliable perspectives within the regulatory framework. It advocates the definition of clear targets within the regulatory framework, although it insists that the framework should remain open to technology and unbiased toward energy sources, while offering the greatest possible scope of freedom. dena therefore advocates a uniform (nationwide) regulatory framework that is as simple as possible.

To further this goal, dena organises, among other things, expert dialogues and expert round tables for representatives from industry and politics. In this way, dena supports the development of content and political thrust in legal requirements such as the German Energy Saving Ordinance.

Increasing energy efficiency through education

The acceptance of measures to increase energy efficiency in the building sector must be achieved using comprehensive information campaigns, competent advice and expert planning combined with targeted state funding. Current instruments within the regulatory framework, funding and market cultivation should therefore be expanded and strengthened in a deliberate manner. Moreover, an individual concept must be prepared based on independent, qualified advice on energy to select the right energy source and most suitable technology for each individual building.

German Energy Saving Ordinance surgeries for energy consultants

As part of its expert portal for energy-efficient construction and renovation (FEBS), the dena team offers surgeries for experts that are intended to ensure the provision of qualified advice on energy. For questions regarding special projects related to the German Energy Saving Ordinance, energy consultants can contact the dena team by telephone or use the online contact form from 10 a.m. to 12 p.m. on Mondays, Wednesdays and Thursdays and from 2 p.m. to 4 p.m. on Mondays. Experts will find additional information on the German Energy Saving Ordinance, standards and laws in the expert portal for energy-efficient construction and renovation (FEBS), which replaces the dena Service for Experts.
