Purpose of the work
After long, controversial discussions, the main Swiss standard on thermal insulation and airtightness, SIA 180, was finally amended in summer 2014. In addition to changing the permitted limits to the envelope-area value of q50, it also gives some indications as to the airtightness design and its implementation in planning and construction. This presentation provides an overview of the approaches that are also of interest to other countries.

Purpose of the work
Wooden flat roofs are being increasingly constructed without the tried and tested sub- ventilation layer of the sealing sheet. However, some regulations refer to the high risk of damage to such structures if the sealing on top of the insulation is largely vapor proof. This research was to analyze whether more recent recommendations, as for example installing a variable vapor retarder, lead to a significant reduction in the risk of damage.

Purpose of the work
The German Industrial Standard DIN 4108-7 has been the standard to stipulate the requirements as well as recommendations for planning and implementing airtight construction for a long time (since 2001). However, the principles of airtight building have not yet been well established in general building practice.

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.
