Experimental studies - Building physics investigations in condensation water on plaster surfaces

Abstract

In recent years, surfaces of plaster facades increasingly have been covered with algae. This effect is reinforced by improved thermal insulation of the building. Envelope e.g. due to the use of plastics, as well as the climate change and lower air pollution. The accumulation of condensation water is therefore of decisive importance. So far, the amount of condensation water was determined with static weight methods. New developments in material research attempt to illustrate the susceptibility to condensation with different measurement methods. The differences can be seen in various systems and materials. Developing a model representation for the future planning of facades is thus possible for new and the existing building. This model can be used to derive new characteristics for new facade design.
