Building air infiltration rate is required as an important input in the calculation of building heat loss. Tests to directly measure infiltration rates are complex and time-consuming to perform, and are therefore usually substituted with an airtightness test as a more efficient alternative. An empirical ratio, or sometimes an infiltration model, is then used to predict the building infiltration rate from the measured airtightness value. For instance, in the United Kingdom the building air permeability measured by a steady pressurisation test and reported at 50 Pa

Air leakage in building envelopes is responsible for a large portion of the building’s heating and cooling requirements. Therefore, fast and reliable detection of leaks is crucial for improving energy efficiency.
The AIVC -TightVent - venticool 2023 Conference: “Ventilation, IEQ and health in sustainable buildings” will be held during 4-5 October 2023 in Copenhagen, Denmark.
Abstract submission is still open. Authors should submit their abstracts by March 20, 2023.
We are happy to announce the release of AIVC's Technical note #70: 40 years to build tight and ventilate right: From infiltration to smart ventilation!
As the AIVC was created in 1979, the 40th anniversary of the AIVC was celebrated in October 2019 at the 40th AIVC conference in Ghent. In the context of this celebration, it was decided to publish 2 overview publications:
The 41st AIVC – ASHRAE IAQ joint Conference, co-organized by ASHRAE & AIVC, was held on 4-6 May 2022 in Athens. The event drew around 185 participants (in person and remotely) – academic researchers, engineering and consulting firms, industry representatives, people involved in standardisation, policy makers, manufacturers & stakeholders and international organizations.
During the event, two topical sessions dedicated to building and ductwork airtightness were organized.

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.
