Using future climate data to assess the viability of mixed mode ventilation to decarbonise Australian commercial buildings
Recent extreme climate events have renewed emphasis on the buildings sector to decarbonise by 2050. However, over-reliance on active air systems is proving a key barrier. This study measures annual natural ventilation operating hours based on defining an environmental acceptability threshold range. Furthermore, using Building Energy Simulation (BES) analysis techniques, energy savings are identified for Mixed Mode (MM) buildings in Sydney, Melbourne and Brisbane. Future weather files are embedded to evaluate impacts of 2030 and 2050 climate scenarios. Finally, through integrating historic air quality data, the impact of deteriorating ambient conditions, caused by severe bushfires and pollution, is analysed.
Wardale is a Consulting Engineer as well as a PhD Researcher at the University of Cambridge. He has 15 years’ exposure delivering complex building engineering projects, both from a design and build perspective. Wardale’s primary research relates to fluid mechanics in the built environment. His focus is predicting contaminant dispersion in buildings by leveraging experimental and theoretical eddy diffusion modelling techniques. As an advocate for sustainability, Wardale’s research interests also include passive and mixed mode ventilation, decarbonising heat networks and designing for a zero-carbon future.
