Technical assistance study for the ventilation units product group
Final report - Study
The ventilation unit product group covers a wide range of products for residential and non-residential ventilation in buildings. A ventilation unit is characterised by being equipped with at least one impeller, one motor and a casing. Ventilation units with both exhaust and supply fans are also known as air-handling units. However, the product group also covers ventilation units such as roof fans equipped with only one fan. In order to reduce the energy consumption of ventilation units, ecodesign requirements and energy labelling requirements (for residential ventilation units only) were set... and implemented in two regulations: Commission Regulation (EU) No 1253/2014 (Ecodesign) Commission Delegated Regulation (EU) No 1254/2014 (Energy labelling) The requirements apply from 1 January 2016. To be applicable, the European Commission (Commission) initiated the Technical Assistance Study for the Ventilation Product Group in which Danish Technological Institute (the Consultant) has provided the Commission with technical assistance on draft transitional methods, frequently asked questions, and other technical issues related to the implementation of the regulations. The main outputs of the study are a draft communication from the Commission document including a list of measurement categories, parameters, standards and transitional methods, and a document with frequently asked questions (FAQ) and corresponding answers. In addition, a report on air leakage rates has been elaborated. During the duration of the study (14 month), a project webpage was established for stakeholders (more than 280 subscribers), two stakeholder meetings were held each with about 50, mainly industry, stakeholders, and interim documents and position papers from stakeholders were published on the webpage. More than 100 questions were received from stakeholders. Most of them have been incorporated into the document with the FAQ. Four coordination meetings were held with CEN TC 156 representatives for relevant work groups on methods, implementation and standardisation progress. The Consultant also participated in workgroup meetings on specific ventilation products.
