Worldwide, there is an increasing number of publications related to air cleaning and sales of gas phase air cleaning products. This puts a demand for verifying the influence of using air cleaning on indoor air quality, comfort, well-being and health. It is thus important to learn whether air cleaning can supplement ventilation with respect to improving air quality i.e. whether it can partly substitute the ventilation rates required by standards.

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. With more widespread use it has become increasingly important to understand and quantify the reliability of these tests.

Purpose of the work
Quantification and location of moisture penetration through leak-dependent creeping flows from the room into insulated, lightweight wall structures as a function of design, pressure differential, and leak position.
Method of approach
Pressure-dependent, high-precision through-flow measurement in a facade test stand and determination of the amount and distribution of condensate in a double climate chamber performed on lightweight wall sections with different cavity wall insulation and leak positioning.

Purpose of the work
All too often, we experts and measurement technicians are totally fixated on airtightness issues. Based on three practical cases, I would like to demonstrate that windproofness, minimal convection in the insulation layer, and the convective separation of different structural elements from one another should also be taken into account in order to prevent structural damage.

Purpose of the work
The load-bearing structures of historical wooden buildings have a large number of joints and penetrations that are difficult to seal. For reasons of preservation of historical monuments, wooden buildings often have to be sealed at the interior of the load-bearing structure. The existing substrates in these areas are not well suited for proper execution and, as a complicating factor, the load-bearing structures or parts of these should often remain visible.
