Dr Mark Dewsbury

   Dr Mark Dewsbury

Dr Dewsbury has been involved in the sustainable design of commercial and residential buildings in the public and private sectors for more than 30 years. Since completing his PhD in 2011, he has been a Lecturer in Building Science, within Architecture & Design, at the University of Tasmania. His research focuses on methods of building to improve the construction, thermal performance, indoor environmental qualities, condensation risk management and mitigating surface and interstitial mould growth. His research provides input for the Nationwide House Energy Rating Scheme, CHENATH and AccuRate building simulation programs and the National Construction Code. Most recently, this has included recommendations regarding roof space ventilation and wall system requirements for the NCC 2019, as the first step to address condensation risk and mould growth in new Australian buildings. Mark has undertaken contract research for a broad range of industry and government partners including the CSIRO, State and Federal government agencies, Forest and Wood Products Australia. He is also a principle partner at Carawah, which specialises low energy dwellings.

Jesse Clarke

   Jesse Clarke

Jesse Clarke has more than 17 years’ experience in the construction industry. He holds the technical lead role of the Building Science Manager, servicing Australia and New Zealand. Jesse is an active advocate for a holistic approach to the development of industry guidance, standards and codes. As the chairman of the AIRAH special technical group for building envelope physics he is driving standardisation around the use of hygrothermal analysis (WUFI®) for healthier and more durable buildings.

Tim Law (PhD)

   Tim Law (PhD)

Tim Law (PhD) is an Architectural Scientist, and Principal at Archsciences. He is also a lecturer in Built Surveying at Victoria University. His research over recent years has been into the occurrence of condensation in new code-compliant buildings in Tasmania, and the study of mould and its impact on occupant health.

Tim has found the problem to be very widespread, very serious, and as a nation he has demonstrated that Australia is very far behind under countries in construction quality and legal recourse. He has completed reports for the Tasmanian Building Regulator and the Australian Building Codes Board, and has been working behind the scenes for the inclusion of more robust condensation stipulations into the National Construction Code. He thrives on complex interdisciplinary work involving architectural science, environmental microbiology and public health.
