Implementation by the EU Member States of the EPBD : opportunities and challenges in relation to building airtightness

Building airtightness is not a new topic of interest. Already in the seventies of the last century, intense work was done regarding building airtightness in the Nordic countries. In the Air Information Review of August 1980 (ref. 1) (figure 1), an article entitled Build tight ventilate right already very well described the challenges. Also in 1980, the Air Infiltration and Ventilation Centre (AIVC) published a guide entitled Air Infiltration Control in Housing A Guide to International Practice. This guide, primarily based on Swedish experience, described very well the various aspects of building airtightness.
