LoginMaintaining the airtightness of building envelopes is a key factor for the energy efficiency of buildings. A fast and reliable detection of leaks plays a decisive role, especially during building renovations.
43rd AIVC - 11th TightVent - 9th venticool Conference - Copenhagen, Denmark - 4-5 October 2023

Volume content
Acoustic method for measurement of airtightness – field testing on three different existing office buildings in Germany | 2023 | English | 10 pp
Airborne transmissions take place as a transport of virus or bacteria via the aerosol flow in rooms. The distribution of aerosols tends to be evenly distributed if the flow in the room is fully mixed.
Point source ventilation effectiveness in infection risk-based post-COVID ventilation design | 2023 | English | 10 pp
Measurement method for ventilation effectiveness, more specifically, for contaminant removal effectiveness with a point source corresponding to infector is analysed in this study with tracer gas measurements and infection risk calculations.
Mitigation of airborne transmission of respiratory viruses by ventilation – past, present and future | 2023 | English | 2 pp
The importance of ventilation of spaces for occupants’ health has been known for many years. Ancient Egyptians used natural ventilation to remove dust and thus to reduce respiratory diseases of stone carvers working indoors (Janssen 1999).
There are several knowledge gaps that explains a lack of knowledge on minimum ventilation rates for intercepting airborne respiratory infection.
Airborne exposure has been highlighted during the COVID-19 pandemic as a probable infection route.
The ASHRAE Standard Project Committee on Ventilation and Acceptable Indoor Air Quality in Residential Buildings (62.2) has proposed an addendum to the standard that adds a harm-based Indoor Air Quality procedure as an alternative compliance method
The buildings ‘sector is facing multiple challenges due to the need to generalize a sober approach and to reduce its energy consumption, its CO2 emissions and its impact on climate change, to reduce its environmental impact and its carbon footprin
Users and practices in heating and ventilating homes – why do they behave different than we think? | 2023 | English | 2 pp
We need to improve the indoor air quality for the health of the building users, and we need to optimize and reduce energy consumption for heating, cooling, and ventilation for the sake of the global climate.
At hospitals and healthcare buildings, the ultimate objective is to save lives.
