The French database of building airtightness has been fed by measurements performed by qualified testers since 2006. The database is enlarged each year by more than 65,000 measurements since 2016, making the total number of measurements about 420,000 at the end of 2018. This work presents a statistical analyses...

Seit 2006 geben qualifizierte Messdienstleister ihre Messwerte in die französische Datenbank zur Luftdichtheit von Gebäuden ein. Seit 2016 wuchs sie jährlich um mehr als 65.000 Messdaten an, sodass Ende 2018 insgesamt circa 420.000 Messwerte vorlagen. Diese Arbeit befasst sich mit der Auswertung der französischen Datenbank...
The Air Infiltration and Ventilation Centre and TightVent Europe are organizing the webinar "Inspection of ventilation systems in new regulations in European countries" to be held on November 30th, 2021 at 10:30-12:00 CET. The objective of this webinar is to present new regulation requirements in Ireland, Germany and France.
The 12th International BUILDAIR Symposium will take place on June 25 and 26, 2021 – as a bilingual online conference, in view of the corona situation. The meeting again offers an ambitious programme.

The 12th International BUILDAIR Symposium will take place on June 25 and 26, 2021 – as a bilingual online conference, in view of the corona situation. The meeting again offers an ambitious programme. Among other things, the presentations will deal with measuring techniques, gluing and sealing difficult details, minimizing the air permeability of materials, quality assurance for very technology-intensive objects and measuring technology for very tall buildings.

Airtightness is mandatory, which also makes ventilation concepts mandatory. Today, the construction/renovation of a building without a ventilation system is impractical in terms of energy efficiency. The minimum air change rate and moisture protection must also be taken into account. Unfortunately, in many buildings...

Indoor pollutants and particles pose a threat to human health as people spend 90% of their time in indoor spaces. A proper ventilation system should be able to remove indoor air pollutants, reduce particle depositions, at the lowest energy consumption by that system. In this work, particle concentrations and depositions are presented for two ventilation configurations (1) Displacement Ventilation (DV) and (2) the conventional ceiling supply and return.

This overview focuses on model based control strategies for ventilation in nearly zero energy buildings (nZEB) where slower reactions towards disturbances are expected as a result of high insulation and air tightness of the building envelope (Killian and Kozek 2016). Furthermore, internal heat gains have a higher impact in these kind of buildings. In addition, occupancy pattern can be variable (e.g. in office- and school buildings) and HVAC control is consequently more challenging.
