'Plugging the gaps' Understanding comfort & condensation

'Plugging the gaps' Understanding comfort & condensation

Masterclass Series | 'Plugging the Gaps’ Understanding Comfort & Condensation in the Tasmanian Context Tuesday 20 June 2023 | 4 pm - 6 pm

Tas Chapter | Australian Institute of Architects
1/19a Hunter Street,
Hobart, Tas


Dr. Mark Dewsbury of UTAS and Dr. Steve Watson of RED Sustainability will deliver a 5 session-intensive Masterclass series to build on the existing knowledge base of Architects, relating to the complications and solutions for preventing condensation in the Tasmanian context while improving the quality and performance of buildings.

The first of the series will provide a comprehensive overview of the topics to be covered in further depth in the round table discussions including air, thermal bridging and vapour control and will refer to case study examples.

Over the following weeks, practitioners will be involved in round table discussions after a short presentation on one topic. A case study may be referred to with the opportunity to break down the design and detailing related to the topic, to improve participant understanding.

The Masterclasses will run for 2 hours with a half-hour presentation of the topic and case study followed by case study discussion and general questions. The sessions will have a tea/snack break. The numbers will be capped for the round table discussions.

The first session will also be livestreamed with the potential of holding follow up sessions in Launceston if there is enough interest. Please contact the Tas Chapter directly for more information.


This seminar provides 2 formal CPD point. 2 hour seminar with question time & tea/snack break. The first session will also be livestreams with the potential of holding follow up sessions in Launceston if there is enough interest. please contact the Tas Chapter directly for more information.

Learning Outcomes

On completion of this course participants should be able to:

  • Understand the implications of, and ways to minimise, thermal bridging through the building envelope.
  • Identify key condensation risks during design and documentation.
  • Apply design and detailing strategies to minimise condensation risk and improve building performance
  • Educate clients on how to actively contribute to reducing the risk of condensation
  • Identify key information to include on detailed documentation drawings

NSCA 2021 Performance Criteria

This course will deliver outcomes related to the following Competencies from the 2021 National Standard of Competency for Architects:

PC 24
Be able to prepare and analyse project development options in response to a project brief – its objectives, budget, user intent and built purpose, risk and timeframes, including environmental sustainability considerations.
PC 28
Be able to draw on knowledge from building sciences and technology, environmental sciences and behavioural and social sciences as part of preliminary design research and when developing the conceptual design to optimise the performance of the project.
PC 31
Be able to identify, analyse and integrate information relevant to environmental sustainability – such as energy and water consumption, resources depletion, waste, embodied carbon and carbon emissions – over the lifecycle of a project
PC 33
Be able to investigate, coordinate and integrate sustainable environmental systems – including water, thermal, lighting and acoustics – in response to consultants’ advice.

PC 37
Be able to produce timely, accurate, complete and comprehensible documentation of the design so that it can be constructed.
PC 39
Be able to integrate the material selection, structural and construction systems established in the conceptual design into the detailed design and documentation.
PC 41
Be able to coordinate and integrate input from specialists and consultants into the detailed design and documentation.
PC 46
Be able to produce project documentation that meets the requirements of the contract and procurement process and complies with regulatory controls, building standards and codes, and conditions.
PC 47
Be able to complete and communicate on-time, accurate documents for relevant stakeholders, including drawings, models, specifications, schedules and construction documentation.

PC 58
Complete documentation – including specifications, drawings, schedules, reports, certification and approvals – and other project information for issue to the client and relevant authorities, as required under the construction contract and relevant building and planning codes.
PC 59
Understand and mitigate risks associated with preparing and recording documentation



Since Dr Dewsbury’s first meeting with representatives from the Tasmanian Government, ABCB and BRANZ in 2008, he has been actively pursuing concerns about moisture and mould in Australian buildings that have resulted from design decisions and building regulations, that have often not kept pace with expectations of building occupants, construction systems, energy efficiency requirements and construction stage water control. Whereas Australia has a long-standing nationwide mould problem in buildings, since 2009 the World Health Organisation has stressed that any visible presence of mould within the built environment will affect occupant health. Other nations have adopted transient hygrothermal and bio-hygrothermal simulation tools with Mould Growth Indices (MI) as a key indicator for the suitability of building envelope systems. These tools have also been designed recognising relative humidity control, via structured ventilation, as a key component of surface and interstitial mould mitigation in new energy efficient buildings. Recognising these trends Dr Dewsbury was one of the first researchers in Australia to use non-transient envelope simulation tools, from 2014 and transient simulation tools since 2017. This has included collaboration with the developers of the UK JPA software until 2017 and the developers of the WUFI suite of tools, the Fraunhofer Institute of Building Physics since 2016..



Steve is the founder and Managing Director of RED Sustainability Consultants. He has been active in sustainable design, research, education and consulting for the past 24 years since graduating from Architecture, at the University of Queensland.  In the area of sustainable design and energy efficiency Steve’s expertise in the residential and commercial building sector is extensive.  He has consulted on projects ranging in scale from small single dwellings through to large, multi-million-dollar government and institutional projects. Steve’s work has had a focus on the front-loading of the building design process for better implementation of ESD strategies, as well as a focus on the environmental upgrading of existing residential and commercial building stock.
