Prof. Richard de Dear

University of Sydney, Australia

Keynote lecture: Nudging the adaptive thermal comfort model

Over the last 35 years, Professor Richard de Dear has focused his research career on defining what occupants want and need from their built environments, and assessing the performance of buildings in terms of meeting those requirements. He is currently the most highly cited living researcher in the domain of thermal comfort, with over 250 peer-reviewed papers plus several monographs on the subject. Within that body of research, it is his adaptive model of thermal comfort that’s had the greatest impact, not just on the research community but also on the design and operation of actual buildings. De Dear’s adaptive model underpins the American Society of Heating and the Refrigerating and Air Conditioning Engineers’ thermal comfort standard, ASHRAE 55-2004, 2010, 2013, which in turn, informs several national thermal comfort standards around the world.
