Significant discrepancies have been observed among European countries, regarding the building and ductwork airtightness trends, attributed to differences between national policies, building practices and climate conditions. In Spain and Latvia, minimum requirements for building airtightness are included in national regulations and Energy Performance calculations, but without a mandatory justification by testing and therefore few new buildings are controlled.
The AIVC is inviting you to register for the upcoming webinar "Building and ductwork airtightness trends and regulations in the Czech Republic, Latvia and Spain" to be held on May 9th, 2023 (10:00 - 11:30 CET). Participation is free for all, but prior registration is required.

Many differences exist between countries in the requirements and regulations for ventilation of dwellings, offices, classrooms and other spaces. Sometimes the variation of the ventilation requirements for the same building type between countries is more than a factor of five. There are strong drivers, e.g., climate change, to reduce energy consumption for HVAC and therefore these variations are worth examining. Before reducing ventilation rates, it is critical to understand the reasons behind them.

Significant discrepancies have been observed among European countries, regarding the building and ductwork airtightness trends, attributed to differences between national policies, building practices and climate conditions. Minimum requirements for building airtightness are sometimes included in national Energy Performance regulations with a mandatory justification required by testing or applying a certified approach like in France, or with high default values making airtightness testing implicitly mandatory like in Belgium.
This is a new monthly 60-minute program from ISIAQ/IEQ-GA that is being produced by Healthy Indoors®/IAQNET LLC.
The show is co-hosted by Healthy Indoors’ Founder & Publisher, Bob Krell, and current IEQ-GA President, Donald Weekes. They have real-world experience in a variety of subjects pertaining to the indoor environment, and they are adept at stewarding the conversation to make it both informative and enjoyable.
NILIM and BRI of Japan, together with the Air Infiltration and Ventilation Centre (AIVC) organize a workshop entitled “Towards high quality, low-carbon ventilation in airtight buildings" to be held on 18-19 May 2023 in Tokyo, Japan. The workshop will take place in at Bellesalle Mita Garden (3-5-19 Mita, Minato-ku, Tokyo/Tokyo Mita Garden Tower 2F (Room B+C).
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.
The AIVC -TightVent - venticool 2023 Conference: “Ventilation, IEQ and health in sustainable buildings” will be held during 4-5 October 2023 in Copenhagen, Denmark.
Abstract submission is still open. Authors should submit their abstracts by March 27, 2023.
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.
