General statutory requirements and regulations

Everything you need to know

General statutory requirements and regulations are important elements of both the European and German energy industries. They are designed to actively help achieve better energy standards. First and foremost, companies should make the manufacture of products as energy efficient and environmentally responsible as possible.

Current energy laws such as the German Energy Saving Ordinance (EnEV) and the Ecodesign Directive (ErP) should make existing building stock and all future projects as climate neutral as possible, and thus contribute to a reasonable and better future in relation to energy consumption.

Builders must also adhere to these general statutory requirements. The ever increasing number of regulations means that energy standards increase too, particularly for new buildings. Subsidy programmes complement these regulations by providing financial support for eligible projects. When purchasing a new heating system, it is worthwhile taking advantage of any state subsidies available. The WOLF subsidy support service can show you the most appropriate programme and help arrange the best possible funding.

Overview of general
statutory requirements and regulations

In our dynamic economy, laws and regulations are constantly changing. This makes it all the more essential to be up to date on the current situation. We provide you with an overview of the most important information.

Energy Saving Ordinance (EnEV)

The Energy Saving Ordinance (EnEV) has been setting increasingly higher energy standards, especially for new buildings, since 2002. But owners of older buildings must also observe certain rules. The main objective is for all of Europe to achieve the lowest energy standard by 2021.

For example, this includes the requirement that all floorstanding oil and gas boilers more than 30 years old must be taken out of operation with immediate effect. However, the EnEV 2014 contains a series of exceptions.

Top floor ceilings that do not meet the requirements for minimum thermal protection must be insulated. This means ceilings in heated rooms that adjoin an unheated roof space. Furthermore, the energy performance certificate for buildings has gained in importance. In future, vendors and landlords must be able to present the certificate when a property is being viewed.

Ecodesign Directive
(ErP Directive)

Fridges, dishwashers, washing machines, ovens – it all started with white goods in the 1990s. Today, other energy consuming appliances also carry the European ErP energy efficiency label, such as TV sets, lighting and – since September 2014 – even vacuum cleaners. "ErP" stands for energy related products.

New efficiency label for older heating systems

Since January 2016, the label for older heating systems has been implemented in addition to the conventional energy efficiency labels. This applies to all boilers more than 15 years old. For you as a consumer, the label is designed to provide free information about the individual efficiency status of your boiler.

According to statistics, only 25 % of the 20.5 million heating systems installed in Germany meet the latest engineering standards. As a result, the technical and economic potential for increasing energy efficiency is enormous.

Your heating system installer, flue gas inspector or specific energy consultants are entitled to affix this label. As of 2017, regional flue gas inspectors will be obliged to label any appliances that do not yet have one.
