Measurement of water vapour resistivity of typical Australian building membranes
Since 2010, concern has been raised about wet buildings in Australia. As of May 2019, regulatory performance requirements necessitate condensation risk analysis for new buildings in some climate types.
It is internationally recognised that the use of hygrothermal simulation is a key method to inform water vapour transport through the built fabric. A key component for hygrothermal simulation is material vapour resistivity. In 2018, different methods for establishing vapour resistivity of building materials were presented and discussed.
This presentation will explore the establishment of test facilities and show experiments conducted to obtain pliable membrane vapour resistivity properties.
Until recently Olaoye studied, practised and taught within the fields of architecture and civil engineering. This cross-disciplinary approach has exposed him to the diversities and practical challenges facing the design and construction of new buildings.
Olaoye is currently pursuing PhD studies at the University of Tasmania, with a co-funded scholarship from CSIRO, focusing on “the empirical evaluation of the vapour permeability of Australian building components”. This involves the exploration and completion of experiments to establish the vapour resistance/permeability properties of materials, paints and membranes – providing critical data to inform condensation risk analysis in Australia.
