IAQ

On March 21, 2025, the EDIAQI and LEARN projects co-hosted a webinar titled "Don't Hold Your Breath: Implementing Effective Ventilation Strategies for Healthy Indoor Spaces."

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 (

We are happy to announce that the book of proceedings, PowerPoint presentations and individual papers from the AIVC 2023 conference "Ventilation, IEQ and health in sustainable buildings" held on 4-5 October 2023, in Copenhagen, Denmark are now available to download freely.

On 4-5 October 2023, the AIVC – TightVent – venticool 2023 joint Conference “Ventilation, IEQ, and Health in Sustainable Buildings”, 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 (

On July 7^th 2023, ASHRAE published its pioneering consensus-based, code enforceable standard, developed to reduce the risk of infectious aerosol transmission in buildings, ASHRAE Standard 241, Control of Infectious Aerosols.

On May 15^th, 2023 ASHRAE announced the completion of the first draft of its standard for maintaining healthy indoor air quality (IAQ), with final approval expected in June and publishing anticipated in July.

In November 2022, the Lancet COVID-19 Commission Task Force on Safe Work, Safe School, and Safe Travel released a report proposing new Non-infectious Air Delivery Rates (NADR) for Reducing Exposure to Airborne Respiratory Infectious Diseases, exceeding the current minimum standards, and aiming to help mitigate infection risk and promote health.

Due to extreme increases in energy prices in European countries (as well as other non-European countries), building users may be tempted to take energy saving measures because they can no longer pay their energy bills. This in turn may have adverse effects on the indoor air quality - especially in older and badly insulated homes. This article gives some elementary advice on what people should and shouldn’t do in cold and temperate climates where indoor heating is normally needed in winter.

Benjamin Jones, Dr.Eng., spoke with ASHRAE’s Technical Editor Rebecca Matyasovski about a proposed addendum to Standard 62.2 that considers harm as a basis of regulating contaminants in homes. He also talked about how this type of addenda could be used in other indoor spaces and by other organizations—and why you should always turn on your range hood.
