The DURABILITAIR project, conducted from 2016 to 2019, aimed to assess the durability of air sealing products used in building envelopes. Key findings were presented at the AIVC conferences in 2017 (Nottingham, UK) and 2019 (Ghent, Belgium). This research enhanced understanding of the in-situ characterization of air tightness evolution in homes over time and contributed to developing accelerated aging test protocols under controlled laboratory conditions.
We are happy to announce that the recordings of the AIVC & TightVent co-organized webinar, “Building Airtightness Impact on Energy Performance (EP) Calculations”, held on December 9, 2024 are now available on our website!
Featured Presenters:
Nolwenn Hurel (Cerema, France)
Xiaofeng Zheng (University of Nottingham, United Kingdom)
Valérie Leprince (Cerema, France)

The AIVC is happy to announce the release of a new addition to the AIVC Ventilation Information Paper (VIP) series dealing with trends in building and ductwork airtightness in various countries.
On 9-10 October 2024, the AIVC – TightVent - venticool 2024 joint Conference "Retrofitting the Building Stock: Challenges and Opportunities for Indoor Environmental Quality", was organised by the International Network on Ventilation and Energy Performance (INIVE) on behalf of the Air Infiltration and Ventilation Centre (AIVC), the Building and Ductwork Airtightness Platform (TightVent Europe) and the international platform for ventilative cooling (

The current trend in most Western countries regarding building ventilation is to follow the “build tight, ventilate right” strategy. New energy efficient buildings are indeed getting more and more airtight to avoid energy losses through uncontrolled air leakages. Instead of relying on natural infiltration, ventilation systems are installed to ensure a good indoor air quality (IAQ) with controlled ventilative air flowrates.
