Sustainable Energy Authority of Ireland (SEAI) together with the Air Infiltration and Ventilation Centre (AIVC) organised a symposium entitled " Quality ventilation is the key to achieving low energy healthy buildings " held on 27-28 March 2019 in Dublin, Ireland.

Various studies have shown that ductwork leakage has a major impact on energy use (i.e. increased fan energy use, heating & cooling losses etc.). However, in most European countries, it is not common to perform ductwork airtightness tests, which is probably due to the lack of awareness on the consequences of ductwork leakage.

Cooking is a major source of indoor contaminants, including moisture, odors and particles. Proper venting of cooking activities is an essential part of providing acceptable indoor air quality in homes.

The 11^th International BUILDAIR Symposium “Airtight Buildings, Thermography and Ventilation Systems in Practice” will be held on May 24-25, 2019 in Hannover Germany.

The symposium "Activities of IEA TCP on Energy in Buildings and Communities (EBC TCP)" took place on the 11^th of June 2019 in Brussels, Belgium from 9:00 AM to 5:00 PM. .

The 40^th AIVC conference: “From Energy crisis to sustainable indoor climate – 40 years of AIVC"  was held on 15 & 16 October 2019 in Ghent together with the 8^th TightVent conference and the 6^th venticool conference. There were 204 participants from 28 countries.

Mandatory or voluntary building airtightness testing has come gradually into force in many European countries mostly because of the increasing weight of building leakage energy impact on the overall energy performance of low-energy buildings. Therefore, airtightness levels of new buildings have significantly improved in the last decade.
