Dr Mark Dewsbury is passionate about sustainability and has been involved in the sustainable design of commercial and residential buildings in the public and private sectors for more than 20 years.

His research activities have included contract research for Forest and Wood Products Australia, CSIRO, Department of Industry, Federal Department of Climate Change and Energy Efficiency, CSR Building Materials, Aurora Energy, and a broad range of industry and government partners. His research focuses on methods of building to improve the construction and thermal performance of Australian housing. This incorporates empirical validation, testing and calibration input for the Nationwide House Energy Rating Scheme, CHENATH and AccuRate building simulation programs. Recently, Mark has been conducting desktop and empirical studies on the use of mass-timber products as thermal mass and condensation risks in contemporary building systems in Australian cool and temperate climates.

Biography

Before Mark's move to Tasmania in 1998, he worked with the public and private sectors. His early industry based training was with a national retailer and included retail store planning and design, and merchandising methods for the refurbishment of existing and establishment of traditional and new concept businesses. A career change to the public sector lead to roles as Properties Officer and Senior Properties Manager within the education sector, which included office block refurbishments, assisting in departmental planning and the responsibility for all refurbishment, new works and master planning for eleven TAFE colleges. Mark's move to Tasmania coincided with a return to full time study and the establishment of Carawah. The principle focus of Carawah has been the design and documentation of low to zero energy buildings. Mark's shift into fulltime academic employment with UTAS has seen a strong research and teaching focus on the technics of Architecture with the aim of providing sustainable systems for our future built environment.

Memberships

Professional practice

Mark is a member of the Technical Advisory Committee for the Nationwide House Energy Rating Scheme; the Australian Institute of Architects; the American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc.; the Architectural Science Association; the International Solar Energy Society; and the Alternative Technology Association. Mark is a principle partner at Carawah Environmental Building and Design. Many of Carawah's buildings have been featured in various publications or been made available as open homes for sustainable house activities. Projects include Tasmania's first load bearing straw bale house and Australia's first timber platform supported rammed earth floors. Designs have also included the use of mass-timber elements as thermal mass. Additionally Carawah has designed reed bed and vermilfiltration wastewater treatment systems.

Administrative expertise

Mark's experience in business and project management has included employment by Woolworths Ltd, Bi-Lo, Department of Corrective Services, TAFE NSW, Department of Training and Education Co-ordination and Carawah. The management roles have included the planning, delivery and management of human, financial and physical resources within private sector and public sector business enterprise models. This has ranged from the small scale practice needs of Carawah to the national and regional needs for Woolworths Ltd and TAFE NSW respectively.

Within his current role as a lecturer and post-doctoral researcher, Mark has managed research projects that have been won via competitive grant systems. This has included project development, competitive grant applications, project management, the sourcing of suitable research assistants and the provision of task specific research reports.

  • Empirical validation research examining the thermal performance of buildings and the relative correlation to results from detailed building simulation programs
  • Detailed simulation of buildings for assessment of heating and cooling energy, water consumption, waste water management, electric lighting, embodied energy and carbon sequestration.

Research Themes

Mark's research aligns to the University's Resources and Sustainability and Better Health research themes. His research on the design, construction, operation and simulation of buildings with an aim to reduce the energy inputs and carbon costs at each level is heavily weighted towards the Resources and Sustainability theme area. However, better buildings can also provide a significantly healthier home and workplace. This may be through a more thermally comfortable building, which impacts on blood and respiratory disorders or other built fabric factors. This link between building design and construction and Better Health has been pointedly developed in Mark's recent industry and government collaborative research on interstitial condensation and mould within buildings in most Australian jurisdictions and its possible association with human health.

Collaboration

Mark's empirical validation and building thermal performance research has included in-kind, cash and technical collaboration from Forest and Wood Products Australia, the CSIRO, Department of Industry, CSR building products, Building Standards and Occupational Licensing, Aurora Energy, Kingspan, Daikin, and Tilling. Mark's recent investigation of condensation and mould in buildings has analysed design, documentation and construction practices, with significant support from Building Standards and Occupational Licensing and CSR Bradfords Insulation.

Current projects

Mark is close to finalising research reports on the thermal performance effects of contemporary installation practices for reflective and bulk subfloor insulation, the use of mass–timber elements as effective thermal mass and condensation in Tasmania housing. The subfloor insulation research examined and tested the differences between contemporary and manufacturer specified installation practices for reflective and bulk subfloor insulation systems. The mass-timber as effective thermal mass research has included over a thousand building energy simulations and the measured thermal performance of partition wall and floor systems within test buildings. The condensation research has analysed documentation and construction practices that are likely causing internal and interstitial condensation and mould growth in new Tasmanian homes. This has included the detailed thermal measurement and time lapse photography within affected housing.

Grants & Funding

Mark's empirical validation and built system thermal performance research has received cash and in-kind funding from national industry partners, the CSIRO and state and federal government Agencies. His recent research into condensation risks in new Tasmanian homes has gained attention from national product manufacturers, Standards Australia and the Australian Building Codes Board. Mark is exploring cross disciplinary funding opportunities with post doctoral researchers from the medical sciences due to a growing body of correlation between condensation in buildings and human health.
