L 337/8 Official Journal of the European Union 25.11.2014 COMMISSION REGULATION (EU) No 1253/2014 of 7 July 2014 implementing Directive 2009/125/EC of the European Parliament and of the Council with regard to ecodesign requirements for ventilation units (Text with EEA relevance) THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Directive 2009/125/EC of the European Parliament and of the Council of 21 October 2009 estab- lishing a framework for the setting of ecodesign requirements for energy-related products ('), and in particular Article 15(1) thereof, Whereas: (1) Under Directive 2009/125/EC energy-related products representing significant volumes of sales and trade, having significant environmental impact within the Union and presenting significant potential for improvement in terms of their environmental impact, without entailing excessive costs, are to be covered by an implementing measure or a self-regulation measure regarding ecodesign requirements. (2)  The Commission has assessed the technical, environmental and economic aspects of ventilation units. The assess- ment showed that ventilation units are placed on the Union market in large quantities. The energy consumption in the use phase is the most significant environmental aspect of ventilation units, presenting significant potential for cost-effective energy savings and greenhouse gas emission reduction. (3)  Fans are an important part of ventilation units. Generic minimum energy efficiency requirements for fans have been established in Commission Regulation (EU) No 327/2011 (3). The power consumption of the ventilation functions of fans which are part of ventilation units is covered by the minimum energy performance requirements of that Regulation, but many ventilation units use fans not covered by it. It is therefore necessary to introduce implementing measures for ventilation units. (4) A distinction should be made between measures applying to residential ventilation units and those applying to non-residential ventilation units on the basis of their individual air flow rate because two different sets of measurement standards are used in practice. (5)  Small ventilation units with an electric power input of less than 30 W per air stream should be exempted from the requirements of this Regulation, except for information requirements. Those units are designed for many different applications, predominantly working intermittently and with supplementary functions only, for example in bathrooms. Including those would represent a considerable administrative burden in terms of market surveil- lance because of large sales numbers, while contributing only to a small share of the energy saving potential. However, considering that they offer similar functionalities to other ventilation units, their possible inclusion should similarly be addressed in the review of this Regulation. Furthermore, ventilation units specifically designed to operate exclusively for emergency purposes or in exceptional or hazardous environments should also be exempted, as they are used rarely and for a short time. The exemptions also clarify that multifunctional units which predominantly heat or cool and kitchen range hoods are excluded. The Commission has carried out preparatory studies to analyse the technical, environmental and economic aspects of residential and non-residen- tial ventilation units. The studies have been developed together with stakeholders and interested parties from the Union and third countries, and the results have been made publicly available. () OJL285,31.10.2009, p. 10.
