What Is ErP

What is ErP?

By Andrew Craig, NPD Manager, March 2015

You have probably heard and possibly used the term ErP in recent years (unless you have inadvertently landed here after mistyping a search for Wyatt Earp).

Yet the majority are unaware of the origin, meaning and impact of the acronym. Well ErP is back and, from a commercial product perspective, these three letters may be some of the most important uttered this year.
Google the term and you are presented with pages of ‘Enterprise Resource Planning’, ‘Electronic Road Pricing’ and ‘Energy Recovery Program’ articles and websites. Press on and you will eventually be greeted with the references I am interested in. The information is there to be found (and there is a lot of it) but it can take a bit of wading through and translation. The European Union (EU) is driving towards goals of CO2 emission reductions set within the Kyoto Protocol. To facilitate these goals, the EU adopted the Energy using Products (EuP) directive in 2005, which was renamed the Energy related Products (ErP) directive in 2009. In 2010, this enforced binding minimum standards and relevant limits to improve fan efficiency. In waves through 2013 and 2015, these limits were applied to the spinning bits of our industry (except for those in some special applications or outside of the identified scope). The result is an EU filling up with efficient fans and power stations which can be turned down a notch. You might think the EU boffins would be satisfied. But wait – there is more.

Commission regulation EU/1253/2014 now aims to cover the efficiency of the ventilation unit. This makes sense as the most efficient fan on the market can be made to run inefficiently if squeezed into a tiny space with restrictions all around it. In a similar manner to the Tier 1/Tier 2 implementations of EU/327/2001, regulation EU/1253/2014 will enforce two waves of changes in 2016 and 2018, applied to a fan in a box (within the EU).

There are three key aspects to the regulation:

1. Reference configuration - As every manufacturer uses differing components within their equipment, a reference configuration has been implemented for design comparison to ensure we are comparing ‘like-for-like’
2. Internal specific fan power - This key term is the driving factor of the regulation and relates to the fan power required to overcome the resistance of the enclosure and constituent unit components for a reference configuration unit.
3. Expanded information requirements - Various performance and efficiency points have to be declared or provided to the customer with expanded information made publically available.

The ramifications of this could be a total redesign/redevelopment of entire product ranges or whole company portfolios. Here at Nuaire, we are ahead of the wave and prepared to work within the new requirements… Are you?
