A large number of modern European buildings are equipped with ducted air distribution systems. To investigate the implications of duct leakage, a field study was performed on 42 duct systems in Belgium and France. The measurement data confirm the findings of the few earlier experimental investigations on these matters in Europe. In our sample, the...
Within Annex 23 (`Multizone Air Flow Modelling') of the IEA (International Energy Agency), a large part of the effort went to the evaluation of the developed simulation tool COMIS [J.-M. Fürbringer, C.-A. Roulet, R. Borchiellini, Evaluation of COMIS, IEA Annex 23: Multizone Air Flow Modelling, LESO-EPFL, Lausanne, 1996; J.-M. Fürbringer, C.-A. Roul...
Within the Belgian Radon Programme the Belgian Building Research Institute is responsible for the investigation of techniques for prevention and mitigation of radon problems in dwellings. One of the most regular actions is the installation of a sub-slab depressurisation (SSD) system. As there are no ready-to-use systems available on the Belgian mar...
Conjunction of Multizone Infiltration Specialists (COMIS) is a model that can be used to simulate air flow and pollutant patterns in a multizone structure. Experimental data from air flow measurements in single sided naturally ventilated spaces, common in urban environments, and from cross-ventilated spaces, are compared against predictions from CO...
This paper aims to identify major characteristics of hybrid ventilation systems, whereby a clear distinction is made between ventilation for Indoor air quality control and ventilation as part of a strategy for thermal comfort in summer. Various building projects are used as illustration for the classification.
This paper focuses on the importance of the level of ventilation requirements on the energy demand of non-domestic buildings. At present, we observe a tremendous difference in the ventilation requirements in various countries as well as at the European level. Variations by a factor of 10 of the ventilation rate requirement can be found in the propo...
Ventilation is necessary to provide good indoor air quality to occupants in buildings but can be a major energy consumer. Results from two experimental studies carried in several dwellings and in office buildings show that the use of presence detection (infrared sensor) for controlling ventilation has a potential for substantial reductions in the h...
L'objectif de la ventilation des bâtiments est d'assurer aux occupants une bonne qualité de l'air et un climat intérieur sain. L'apport d'air neuf dilue et évacue les polluants: odeurs et humidité des occupants, polluants engendrés par les activités professionnelles, ...

EBC Annex 5 was first established in 1979 under the name “Air Infiltration Centre” undertaking technical activities and providing information services with the task of minimizing air infiltration energy losses. In 1986, the name was changed to “Air Infiltration and Ventilation Centre” to reflect the importance of the coupling of a good airtightness with appropriate ventilation. Over time, the AIVC has been continuously evolving to respond to emerging concerns, challenges and opportunities.
The Centre’s main goal is to provide reference information on ventilation & air infiltration in the built environment with respect to efficient energy use and good Indoor Environmental Quality (IEQ).
The AIVC's objectives are: to identify emerging issues on ventilation and infiltration in new and renovated buildings; to help better design, implement, hand-over and maintain ventilation systems; and to provide discussion platforms, including conferences, workshops and webinars.
