Biography

Restricting climate change to the “manageable range” will require significant energy conservation in the building sector. In developed countries buildings usually account for at least 40% of total energy consumption, and between 30 and 60% of this energy is used in the provision of indoor climate control for occupant comfort (heating, ventilation and air-conditioning). In New South Wales over 90% of office buildings and about 50% of homes now have air-conditioning. It seems clear that a transition towards an energy-efficient, low-carbon economy is going to impact comfort levels within built environments; all that remains to be answered is “how much?”

Over the last 31 years, Professor Richard de Dear has built a career in the area of human thermal comfort. He has published over 100 peer-reviewed papers and a dozen books and monographs on the subject. Within that body of research it is his work on the “adaptive model of thermal comfort” that has had the greatest impact, receiving over a thousand citations within the indoor environmental literature (and earning him an H Index of 19). De Dear’s adaptive model underpins the American Society of Heating, Refrigerating and Air Conditioning Engineers’ thermal comfort standard, and several other national and international standards/codes are now evolving in similar directions, including most recently, the Netherlands and CEN. Countless “green buildings” around the world have been engineered on the basis of the adaptive comfort model. Every year he receives several keynote lecture and visiting professor invitations to conferences or universities, especially across the Asia-Pacific region where his adaptive comfort model has had its greatest uptake.
