The recent enhancements of the National Construction Code have reduced the amount of energy required to heat and cool Australian homes. To date, the result of these changes, within Australia's temperate and cool-temperate climates, is generally warmer internal temperatures. However, many of these warmer homes are presenting condensation and mould. This is demonstrating a general non-awareness of vapour pressure management within the Australian design and construction professions. This paper discusses research from the architectural and medical science disciplines. The paper identifies a significant gap in appropriate building regulation and building science knowledge within this field in Australia.
