Building airtightness tests have become very common in several countries, either to comply with minimum requirements of regulations or programmes, or to justify input values in calculation methods.
AIVC Projects
The AIVC offers industry and research organisations technical support aimed at optimizing ventilation technology. We offer a range of services and facilities, including comprehensive database on literature standards, and ventilation data.


Internationally there are many different requirements and regulations for ventilation. Sometimes the variation is more than a factor of five.

This project deals with reviewing EBC's Annex 5: "Air Infiltration and Ventilation Centre" activities & contributions on the occasion of the project's 40th year of operation.

The European market for residential ventilation is highly driven by energy performance regulations.

The trend towards more nearly zero energy buildings and much more airtight buildings represents specific challenges for cooker hoods in residential buildings.

There is a trend to perform more ventilation and air infiltration measurements in buildings, either to strengthen commissioning procedures or to learn from field data.

There exist several initiatives in different parts of the world to bring a stronger basis to ventilation requirements in relation to indoor air quality and health issues, for example, at LBNL in th

While it is generally accepted that ventilation-whether natural, mechanical or hybrid- is needed to provide acceptable indoor air quality and prevent building damage, there are debates about the ac

With the trend towards low-energy buildings, the importance and the interest for building air tightness is increasing.

The COVID-19 pandemic has an unprecedented impact on all of us, both personally and professionally.

The trend to increasingly complex ventilation controls (particularly for residences) is leading to many new possibilities related to IAQ and energy optimization.

The current development in building energy efficiency towards nearly-zero energy buildings represents a number of new challenges to building design and construction.

An increasing number of countries (e.g.

There have been many new sensors introduced on the market claiming that they can perform accurate measurements of Indoor Air Quality.
