Climate change is increasingly recognized as a driver of indoor environmental health risks, particularly through the promotion of mould growth, including strains resistant to heat and fungicides. As people spend over 80% of their time indoors, the growing vulnerability of buildings to elevated humidity and moisture poses a significant public health risk. Mould exposure has been linked to respiratory and cardiovascular illnesses, allergic reactions, cognitive decline, and diminished quality of life—outcomes reflected in rising Disability-Adjusted Life Years (DALYs).
The Air Infiltration and Ventilation Centre (AIVC) is pleased to announce its upcoming international workshop, taking place on April 21–22, 2026, in Madrid, Spain, under the theme “Climate Change, Ventilation and Resilience.”
The workshop will provide an opportunity for Spanish researchers and professionals, as well as international experts, to present and discuss recent advances in relation to the challenges that climate change imposes on buildings, related to indoor environmental quality, ventilation, human health and sustainability.
The 46th AIVC conference "Innovations in Smart Ventilation and IEQ for Resilient and Adaptive Buildings" will take place on September 30 & October 1, 2026 at the Songdo International District in Incheon, Republic of Korea. This international event will be held jointly with the 14th TightVent Conference and the 12th venticool Conference.
We’re happy to announce that the recordings and presentation slides from the recent AIVC-TightVent webinar, “Inspection of ventilation systems in non-residential buildings” held on June 5, 2025), are now available on our website.
We’re pleased to announce that the recordings and presentation slides from the AIVC-TightVent webinar, “Building and Ductwork Airtightness Trends and Regulations in Estonia, Germany, and the U.S.” (held on May 12, 2025), are now available on our website.
Featured Presentations:
Introduction to the AIVC VIP Series on airtightness regulations
Nolwenn Hurel (Cerema, France)
Estonia: National trends and requirements

Major discrepancies are found between countries regarding both the building and ductwork airtightness trends, primarily due to varying national policies, construction practices, and climates. In some countries, minimum airtightness requirements for buildings are included in regulations, such as in U.S. states that have adopted the IECC energy code, which mandates testing to justify airtightness in residential buildings. In Estonia and Germany, achieving high airtightness in the building envelope is encouraged by disadvantageous default values for Energy Performance calculations.
