Feasibility Study EPBD19a - Stock of ventilation systems in EU buildings and foreseen evolution for 2030, 2040 and 2050

Résumé et principaux résultats

Article 19a of revised Energy Performance of Buildings Directive includes the requirement for the Commission to perform, before 2020, a feasibility study to clarify the possibilities and timeline for introducing the inspection of stand-alone ventilation systems, e.g., the development or improvement of technical standards, guidelines and practices, or the possible extension of the mandatory regular inspection requirements to stand-alone ventilation systems. In this context, a technical study has been contracted to INIVE to provide support to the Directorate-General for Energy of the European Commission. CETIAT provided leadership for the work.
This report (one from a series of four reports) provides an assessment of the stock and sales of stand-alone ventilation systems in EU countries from the consolidation of existing data. An assessment of the evolution of this stock for 2030, 2040 and 2050 is also provided. Insufficient information was found on natural ventilation systems to be able to assess their stock and market. The current stock (2020) of mechanical ventilation systems is estimated to 139 million (mean value), between a minimum value of 86 million and a maximum value of 190 million, of which 93% residential and 2/3 of decentralised unidirectional residential systems. The current annual sales are estimated to almost 8.5 million units, of which 93% residential and 60% of decentralised unidirectional units. The evolution of stock and sales up to 2050 has also been estimated from the consolidation of the existing data, with a large uncertainty due to the low number of information sources and the inconsistency of the available data. The penetration of balanced ventilation systems should increase. Examples of publications have been analysed that show characteristics of stand-alone ventilation systems in the existing stock. A large proportion of systems do not provide the designed or required air flow rates.
