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)

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.
The AIVC and TightVent are pleased to invite you to the webinar titled "Inspection of Ventilation Systems in Non-Residential Buildings", scheduled for June 5, 2025, from 13:30 to 15:00 CET.
Participation is free, but registration is required.

The AIVC is pleased to announce that the slides from the recent international workshop “Indoor Environmental Quality in Sustainable Buildings” are now available online.
The workshop took place on 1–2 April 2025 in Stuttgart, Germany, and brought together German and international researchers, engineers, and experts to exchange knowledge and share recent developments on indoor environmental quality (IEQ), ventilation, health, and sustainability in buildings.
We’re pleased to announce that the recordings of the AIVC webinar, “Recent Standards and Guidelines on CO₂ Application and Interpretation”, held on March 17, 2025, are now available on our website!
Featured Presentations:
Background on Indoor CO₂ Application – ASHRAE Position Document & ASTM Standard D6245 Andrew Persily (NIST, USA)
Demand-Controlled Ventilation – ISO 17772-1 (EN 16798-1) & ASHRAE Standard 62.1 Bjarne Olesen (DTU, Denmark)
