On behalf of the Air Infiltration and Ventilation Centre (AIVC, and TightVent Europe (the European Building and Ductwork Airtightness Platform,, INIVE organizes an airtightness workshop 28-29 March 2012 in Brussels. Registration information at:

Should there be specific airtightness requirements? If so, should they be differentiated with climate, building usage, and ventilation system type? Should there be a minimum level of air leakage?

Are quality management approaches appropriate instruments to push and/or pull market players? What are the pitfalls to avoid? What can be learnt from pioneering experience in this field, including in the inspection of ventilation systems?

How does airtightness changes with time, and how does that affect the building’s performance over its lifetime?

The objective of this workshop is to discuss those questions with key experts. It is divided into three parts:

  1. Philosophy for setting airtightness requirements: recommendations and pros and cons of various approaches
  2. Durability of seals and bonds: what we know and where we need to go
  3. Dealing with airtightness in the construction process: lessons learnt and potential for quality management approaches.
