The AIVC is inviting you to register for the upcoming webinar "Smart ventilation in non-residential buildings. How to assess? How to design?" to be held on December 12^th, 2023 (15:00 - 16:30 CET). Participation is free for all, but prior registration is required.

For further information on the detailed agenda, registration etc. please follow this link.

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 (

The ASHRAE Singapore Chapter (ASC)  in collaboration with the Air Infiltration and Ventilation Centre (AIVC) is organising a 1 ½ -day workshop to be held on April 18-19, 2024 in Singapore. The workshop will be led by experts from the AIVC and the ASHRAE Singapore Chapter. It is intended for engineers, architects, and other professionals who want to learn more about ventilation, IEQ and sustainability.

The event will take place at the Surbana Jurong Campus.

The workshop main themes include:

We are pleased to announce the release of a YouTube collection including some of the highlights of the 43^rd AIVC conference: “Ventilation, IEQ & health in sustainable buildings” held on October 4-5, 2023, in Copenhagen, Denmark. The playlist includes a selection of recorded presentations from the opening session’s keynote speeches as well as the recordings of the closing session’s best paper, best poster and student competition awards:

Paper, poster & student competition awards were given during the closing session of the joint 43^rd AIVC – 11^th TightVent – 9^th venticool conference: “Ventilation, IEQ and health in sustainable buildings” held in Copenhagen, Denmark on 4-5 October 2023.

Best paper award:

The jury for the best paper award, consisting of Hilde Breesch (KU Leuven, Belgium), Benjamin Jones (University of Nottingham, UK), Valérie Leprince (Cerema, France) & Iain Walker (LBNL, USA) nominated the papers listed below:

The evaluation questionnaire of the 43^rd AIVC conference: “Ventilation, IEQ & health in sustainable buildings” was sent out to 200 attendees of the event. 98 participants filled in the evaluation form. We are happy to share with you a summary of the main results!

General outcomes:

The AIVC has just released a new publication!

AIVC's Ventilation Information Paper #47: High-rise buildings airtightness – error due to stack effect on point measurements gives guidance to perform a pressurization test in high-rise buildings and suggests new criteria to replace standard requirements when they cannot be met.

A special issue of Buildings (ISSN 2075-5309)  is now open for submission.

This Special Issue is motivated by the importance of the airtightness of buildings in terms of indoor air quality and the energy implications of heat transfer. Currently, it is not possible to design and construct nZEB buildings without taking this parameter into account, and it is essential that we can determine this parameter in buildings to be renovated in order to achieve a significant improvement in their final energy consumption. 

The date for the AIVC -TightVent - venticool 2023 Conference: “Ventilation, IEQ and health in sustainable buildings” is now approaching quickly! The conference will be held during 4-5 October 2023 in Copenhagen, Denmark. 

More than 190 people have booked their seats for the event!

The event will open with a welcome reception on Tuesday October 3, 2023 at 19:00. 

The conference will start on Wednesday October 4, 2023 at 09:00. On-site registration will be open from 08:00.
