'Plugging the Gaps’ | Thermal Envelopes

Wednesday 29 May 2024 | 5 pm - 7 pm 
| Live Webinar Event



The aim of the thermal control layer is to control the flow of heat into or out of the building. Typically in a cool climate the aim is to retain heat within the building for as long as possible. The session will cover issues of: continuity of the thermal control layer; windows, walls, roofs and floors as elements of the thermal control layer; and strategies to avoid bridging of the thermal control layer.

Please note: The information provided throughout the series is based on current research and understanding at time of series delivery. It is expected that participants will research and identify their own solutions based on individual circumstances.


This seminar which forms part of the 4 session Plugging the Gaps|Understanding comfort & condensation in the Tasmanian context series provides 2 formal CPD points and can purchased as a stand alone webinar. 
In person attendance is only available to registrants for the entire series to ensure cohesive engagement in the group setting.
Please refer to Plugging the Gaps Series registration page for Series registration.

Learning Outcomes

On completion of this course participants should be able to:

  • Build on existing understanding of thermal, air, and vapour control layers
  • 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

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 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..
