Purpose of the work
To review the impact of air tightness testing in construction in Ireland since the introduction of mandatory testing under the National Building Regulations in 2008 and the subsequent enforcement of a National Certification Scheme.
Method of approach
Review of National Building Regulations in 2008 & 2011 and implications on buildings being constructed and the industry's acceptance.

Purpose of the work
Can the minimum air change in naturally window-ventilated units be covered only through leakages?
Content of the presentation
In general, the infiltration airflow rate is dependent on meteorological conditions, especially wind pressure on the building / unit, and with regard to thermal effects, the temperature differential between the interior and the exterior, i.e. the infiltration airflow varies strongly.

Purpose of the work
Many top-floor apartments and single-family homes from the ’80s and ’90s had been insulated in the roof area using aluminum-clad panels or PE foils and had frequently been covered with profiled wood. These buildings suffer from a significant lack of airtightness that can be retrofitted from the inside with a high technical quality. The improvement in airtightness achieved by this approach in most cases shows better results than a retrofit from the outside.

Purpose of the work
Is it possible to estimate an air infiltration flow rate, based on infrared images?
Method of approach
Laboratory tests and numerical simulations
Content of the presentation
This paper discusses laboratory measurements on a small test house. IRT measurements and (de)pressurization tests were performed on different types of junctions, e.g. at the window-wall interface. The results were analysed by calculating the temperature factor, to compare IRT images from different joints.

Purpose of the work
When it comes to evaluating the quality of building work, technical and legal perspectives often clash. This is probably particularly true when it comes to evaluating the airtightness of building envelopes. This presentation is an attempt at clearing up frequent misunderstandings and at formulating questions that would help to combine the technical and legal ways of assessing quality in the most practical manner possible.
