Are condensation and mould problems in Australian homes arising from the Australian building regulations?

As a result, and in order to achieve energy efficiency requirements, houses have incorporated greater quantities of envelope insulation and improved air tightness.
It has been found that occupants residing in newly constructed builds are reporting increased occurrences of condensation and mould. It is internationally accepted that mould spores are linked to several immunology and allergy conditions, which can cause lifelong illnesses.
This presentation will look at how the lack of regulatory guidelines regarding the choice of building materials is likely to cause water vapour condensation and moisture accumulation in contemporary building envelope systems, leading to other moisture-related problems that affect structural durability and human health. Condensation risk was established using a simulation software and Shruti will share these results.
