The Air Infiltration and Ventilation Centre (AIVC) together with Fraunhofer IBP in Germany organized a workshop entitled “Indoor Environmental Quality in Sustainable Buildings" to be held on 1-2 April 2025 in Stuttgart, Germany.
Climate change is leading to increasingly frequent and severe heatwaves, which elevate the risk of human thermal stress in indoor environments. These conditions can make buildings uninhabitable during extreme events and long after they have passed. Therefore, it is crucial to design future-proof buildings and systems that can withstand such shocks and mitigate their impact on human well-being.
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.
The 14th International Buildair Symposium: "Airtight Buildings, Thermography and Ventilation Systems in Practice" will take place on May 16 and 17, 2025 in Hanover, Germany.
The inspection of ventilation systems in non-residential buildings is a growing priority across Europe, driven by the need for better energy efficiency and indoor air quality. Inspection protocols can be challenging to develop as, unlike for residential buildings, a wide range of building types and use has to be covered.
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.
The conference "IEQ 2025: Rising to new challenges: Connecting IEQ to a sustainable future”, organized by ASHRAE and AIVC, will be held in Montreal, Quebec, Canada on 24-26 September 2025. The conference will also be the 13th TightVent and 11th venticool conference.
Recent years have seen important evolutions in building ventilation regulations, inspection practices, and market developments across Europe, with significant differences between countries.
