A deep dive into the humble cavity


Air-filled cavities are ubiquitous in Australian construction. Roof spaces, wall cavities and sub-floor spaces can all play an important role in the insulation and moisture management in our buildings.

This presentation will take a deep dive into the heat transfer, airflow, and moisture transfer occurring in cavities. Results from full-scale experiments and validated models will be used to illustrate interesting aspects of the physics involved, and to demonstrate the strengths and limitations of the various calculation methods and test methods that are typically used to measure or model cavity performance.

About Dr Alan Green

Dr Alan Green is a Research Fellow at the Sustainable Buildings Research Centre (SBRC), University of Wollongong. He obtained a PhD at the SBRC with research on water spray systems to improve the bushfire resistance of buildings, and has a background in mechanical engineering.

Alan has a keen interest in fluid dynamics, which has given him the opportunity to work alongside researchers in the Netherlands, UK, USA and Portugal. His current research focuses on technical aspects of building physics and resilience, with active projects involving experiments at various scales and mathematical modelling.
