ErP Directive: Facts and Figures

The ErP Directive demands high minimum efficiency ratings for fans.

By adopting the Kyoto Protocol, the European Union has undertaken to reduce CO2 emissions by at least 20 per cent by 2020. To achieve this climate goal, the EU adopted the EuP Directive (Energy Using Products Directive) in 2005. Re-named ErP Directive (Energy Related Products Directive) in 2009, its purpose is to investigate the energy-saving potential of numerous energy-consuming products and to stipulate minimum requirements. Binding limit values for fans were set down in March 2011.

ebm-papst fans featuring GreenTech EC technology surpassed the legal requirements of the ErP Directive for stage 1 (up to 2013) and stage 2 (up to 2015) even before these were introduced.

Facts and Figures on the Directive

  • Thanks to the Directive, 20,779,200 tons of CO2 have been saved since 2012. That corresponds to a saving of 46,800 GWh of electricity.
  • In 2015 alone, ebm-papst replaced 270,000 low-efficiency fans with more efficient models.
  • Every year, ebm-papst invests more than 106 million euros in the development of energy-efficient fans and motors.
  • The European fan industry generates an annual turnover of around 5 billion euros.
  • The stringent limit values stipulated by the fan directive help to secure qualified jobs in Europe. Approximately 55,000 people work in the European fan industry.

Which fans are affected?

Fans of all types (axial fans, centrifugal fans with forward-curved and backward-curved blades, tangential blowers and diagonal fans) with a power consumption of between 0.125 kW and 500 kW are affected. This applies to fans that are operated as "stand-alone" devices or are integrated as a component in a device or system.

ErP Directive: Facts and Figures

How will it be implemented?

The EU defines minimum efficiency ratings in the ErP implementing regulation for fans. These are defined on the basis of the power consumption at the optimum point. Determination of whether a fan conforms to the ErP implementing regulation always involves assessing the efficiency of the fan as a whole, i.e. the entire unit comprising control electronics (if fitted), motor, and fan impeller.

To which countries does the directive apply?

The Directive is binding in the 27 EU member states. All fans brought onto the market in Europe are subject to the Directive, including those imported into Europe from third countries. The minimum efficiency requirements also apply to fans fitted in devices that are imported into Europe.

A Directive that really works

The ambitious climate goals of the EU cannot be attained without energy-efficient technologies. And stringent limit values ensure the ongoing advancement of these. There is an established approach to regulation at EU level. Depending on viewpoint, this is referred to as cascading, supplementary or double regulation. The idea is to set down limit values for an entire building, for the devices installed in it and for the fans fitted in the devices.

Multi-tiered regulation offers three major benefits:

  • Efficient components yield overall efficiency
  • The same rules apply to everyone on the market
  • There are no loop-holes

Good for the environment, jobs and innovation

Some people view the strict regulations for fans stipulated in the Ecodesign Directive EU 327/2011 as something of a burden, but they do in fact make good sense. Certain inefficient fans no longer satisfying the efficiency requirements have disappeared from the market, for example, and have been replaced by far more energy-efficient fans. This has resulted in the use of less power and thus reduced harmful CO2 emissions into the atmosphere. An integrated system of stringent limit values also provides an incentive for innovation in the industry. This keen competition creates highly qualified jobs in Europe. Since 2013 power consumption and thus CO2 emissions have been considerably reduced thanks to the fan directive.

The future belongs to GreenTech EC technology

Viewed in this light, the innovative GreenTech EC technology developed by ebm-papst is the ideal solution for electrically-driven fans. In contrast to fans with asynchronous motors (AC motors), GreenTech EC motors from ebm-papst attain efficiency levels of greater than 90 per cent. This makes it possible to save considerable amounts of energy as compared to conventional AC solutions. The speed control function of GreenTech EC fans also means that the air volume can be adjusted to suit the given requirements. This has the positive effect of saving even more energy. Thanks to the perfect interaction of motor, electronics and aerodynamics, ebm-papst GreenTech EC fans not only offer excellent energy efficiency, their optimized commutation techniques and the aerodynamic design of the fan impellers also make them extremely quiet-running. And what's more: they offer the added benefits of reliability and a long service life.
