Article 19a of the Energy Performance of Buildings Directive (EPBD) requires the European Commission to conduct a feasibility study on the possible introduction of the inspection of stand-alone ventilation systems and an optional building renovation passport. In this scope, a technical study has been contracted to a consortium formed by INIVE and BPIE who, together with a broad range of experts in the required fields, provide technical support to the Directorate-General for Energy of the European Commission. The latest updates on the technical study can be found on the EPBD 19a website.
One aim of the study is to clarify the possibilities and timeline to introduce the inspection of stand-alone ventilation systems in buildings. Inspections can be considered as a way to improve the performance of ventilation systems. Such inspections can take different forms, e.g. mandatory or voluntary, operated by independent inspectors or by the installation/maintenance staff, shallow or in-depth, etc. Alternative approaches to inspections (e.g. awareness raising) can also be effective and are in the scope of this study.

With this survey, we would like to understand your views on inspection of ventilation systems and alternative approaches. The results of the survey will feed the study.

If you want your voice to be heard, please fill in this survey by April 15, 2019.

A survey for second topic of the feasibility study - building renovation passports-, is now also open.

Scope of the survey

This survey covers:

-          Stand-alone ventilation systems, i.e. systems whose sole function is to ventilate a building; the inspection of combined heating and ventilation systems, and of combined air-conditioning and ventilation systems is covered by articles 14 and 15 of Directive 2018/844/EU

-          Ventilation systems in residential and non-residential buildings, except industrial buildings

-          Newly-installed ventilation systems in new, renovated or existing buildings

-          Ventilation systems already installed and in operation in existing buildings

-          All types of stand-alone ventilation systems: mechanical, natural, hybrid together with their controls

-          Initial or regular inspection(s)

-          Various levels of inspection: from simple visual check based on a check-list to exhaustive measurements on the installed system

-          Various inspection objectives: checking of good operation, ductwork airtightness, energy efficiency, air flow-rates, indoor air quality, thermal comfort, system cleanliness, noise level, etc.

-          Inspections operated by installers, maintenance workers, independent inspectors or others

Background questions


For research purposes we need to retrieve some information on your background and expertise.  Although we ask you for your contact details, your answers will be processed anonymously.

Question Title

* 1. Personal details

Understanding the challenge – current performance of ventilation systems
Please remember that your answers must focus on stand-alone ventilation systems, i.e. systems whose sole function is to ventilate a building, thus excluding combined heating and ventilation systems and combined air-conditioning and ventilation systems.

Question Title

* 6. What is your opinion about the current overall performance of installed stand-alone ventilation systems? (select one item that fits the best with your opinion)

Question Title

* 7. Which issues can lead to poor performance (indoor environment, energy performance) of stand-alone ventilation systems?

  Strongly disagree Disagree Indifferent Agree Strongly agree
Poor quality of ventilation products
Lack of information about product characteristics which results in sub-optimal design and installation
Inadequate design of building ventilation systems
Inadequate execution of the installation works
No or insufficient commissioning by installers
Insufficient maintenance
Very strong price competition
Lack of inspection of ventilation systems
Lack of awareness of clients about ventilation needs and rules of use and maintenance
Change of building use without adaptation of the ventilation system
