ErP stands for ‘Energy Related Products’. The ErP Directive 2009/125/EC is focussed on reducing energy consumption of fans.  Regulation 327/2011 applies to fans with input powers of between 125W and 500kW.

ISO 12759 has been established to allow fan producers to measure the efficiency of fans in a consistent manner and determine compliance to the directive.

The European Union has promised to reduce CO2 emissions by 20 per cent by 2020.  The Energy Using Products Directive (EuP Directive) was put in place in 2005 but was renamed as the Energy Related Products Directive (ErP Directive) in 2009. Minimum efficiency levels were defined and became mandatory in June 2010. The directive is mandatory for all twenty seven EU countries. The directive applies to all fans sold or imported in Europe as well as those integrated as components of other devices that are imported into Europe. 

These efficiency values became binding in January 2013 and were later reviewed to increase efficiency values in January 2015. Whilst we are not completely sure what will happen in the future, these values along with a review of technologies is due to come into place in 2020.
