Diffusion of water vapour, monitoring and risk analysis of wooden walls

Original language description

This paper presents an experimental study of 4 different building structures of used to construct modern timber houses. These structures are monitored on the Experimental Timber Framed House - EXDR since 2012. Since the EXDR is located outdoors, the materials and structures are exposed to actual real life climatic conditions (i.e. weather change rate and solar gains) and are monitored under real-time. As for the indoor conditions, those can be controlled in full scale. It is possible to change the indoor air temperature, humidity production and air exchange rate. The main aim of this experimental project is to use the measured data in the development of a new improved model for mould risks prediction. The data are collected by a data logger developed under DIY framework from two prototyping platforms, the Arduino and the Raspberry Pi. This peculiar paper presents how water vapour affects existing structures created with the application of a vapour barrier from PE based foils or oriented strand boards (OSB). An analysis of mould growth risks model and its comparison to measured mould growth risks is also presented.
