The impact of selected climate data on the outcomes of building energy and hygrothermal simulations

This presentation is based on sustaining the habitation of buildings in the broadest possible sense – culturally, programmatically, economically, socially, environmentally. Building physics are embedded in design, supporting With anthropogenic climate change upon us, there is a growing awareness of the effects of changed (usually increased) temperature, humidity, solar radiation and precipitation converging on the escalation of extreme weather events on building performance.

Accordingly, the types of climate data used to simulate building performance in order to design resilient and energy efficient and peak load constrained buildings into the future, we must respond.

This research proposes a novel methodology for an extreme multi-year climate dataset and evaluate it in building energy and hygrothermal simulations with typical average climate data over a period of thirty-two years (1990-2021).

Exemplary Energy
Trevor Lee is a Canberra-based architect and consultant on energy conservation in the built environment through the multi-disciplinary firm Exemplary Energy. He is lead author of the Australian Solar Radiation Data Handbook and team leader developing the expanded Australian Climate Data Bank – 1990–2021 for around 250 locations.
Researching the impact of climate change on the built environment, this work flowed into the Ersatz Future Meteorological Years (EFMYs) data sets for two scenarios to 2030 and four scenarios to 2050.

From 1990 to 2004 Trevor served as executive director of the funds manager Australian Ethical Investment Ltd (ASX code AEF), now managing over $6.5 billion. 


Freya Su
University of Tasmania
Freya Su is a PhD student in the architectural science lab at the University of Tasmania. Her PhD investigates the relationship between hygrothermal simulation and climate data. Before beginning her current studies, she worked as a research assistant with Mark Dewsbury, M.AIRAH, and co-authored condensation-related publications. In 2015, Freya founded Snug House Tasmania, conducting airtightness testing and energy-efficiency assessments in a multi-disciplinary building design studio.
