Keynote Speakers

The Organizing Committee of the 50th International Conference of the Architectural Science Association is pleased to announce Ms Lisa Heschong (founding Principal of Heschong Mahone Group (HMG)), Professor Richard de Dear (University of Sydney) and Industry Professor James Hayter (University of Adelaide and Director of Oxigen) as Keynote Speakers of the conference.



Ms Lisa Heschong

Ms Lisa Heschong is renowned worldwide amongst architectural students, teachers, and practitioners, for her most loved book Thermal Delight In Architecture (MIT Press). She also co-authors Residential Windows: A Guide to New Technologies and Energy Performance (WW Norton), along with numerous web and journal publications. Early in her career, she taught architectural design at UC Berkeley, and has since spent decades educating other design professionals on energy efficiency.

Ms. Heschong is also well known for having led the research that found a correlation between daylight in classrooms and improved student performance. She has continued with daylighting research since then, leading an international effort to establish a new set of standards for annual daylight performance metrics. She has also helped develop energy efficiency codes and standards in California and in the US, and led multifamily energy efficiency programs, both new and retrofit, for the California utilities for the past 15 years.

Ms. Lisa Heschong has a B.Sc. in Conservation of Natural Resources from UC Berkeley and a Master of Architecture degree from MIT. In 2011 she was honored with the Haeker Award for lifetime achievement from the Architectural Research Centers Consortium, and in 2014 as a Fellow of the Illuminating Engineering Society of North America.

Ms. Heschong, was a founding Principal of the Heschong Mahone Group (HMG), VP and Chief Building Scientist at TRC Energy Services, and a licensed architect for 30 years. She recently moved to Santa Cruz, with her husband, sail boat, and two horses, and is delighted to be a new member of the teaching team at the UCSC Environmental Studies Department.



Professor Richard de Dear

Over the last 35 years, Professor Richard de Dear has focused his research effort on quantifying what occupants want from their built environments – Indoor Environmental Quality. 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 has had the greatest impact, not just on the research community but also on 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.

Uptake of the adaptive comfort model can best be explained against the backdrop of global climate change. It is imperative that buildings mitigate their impact on the environment wherever possible, and adapt to climate change where it is not feasible. Nowhere are these issues more pressing than in the emerging BRICS economies, explaining why de Dear’s research attention is now concentrated on East and South Asia where the intensity of construction activity is greatest.

Prof De Dear has held positions at the Technical University of Denmark, National University of Singapore, Macquarie University, and since 2009, the University of Sydney where he is the inaugural Director of the Indoor Environmental Quality Lab in the Faculty of Architecture. De Dear is also currently serving as an editor for Energy and Buildings, Indoor Air, and ASHRAE’s archival research journal, Science and Technology for the Built Environment.



Professor James Hayter

James Hayter is regarded as one of Australia’s most respected design professionals in the fields of landscape architecture and urban design. His studio, Oxigen, completes a variety of planning and design projects each year, including award winning projects of national and international profile.

Whilst practising in the public, private and academic sectors, James has developed a broad understanding of the design profession and its requirements to the planning, design and construction industries in Australia, making him a valuable contributor towards the advancement of the design professions in Australia.

James has excellent strategic planning skills and an ability to conceptualise projects and requirements for implementation. He brings comprehensive technical skills including a desire to try innovative ways of resolving the requirements of a project and design skills proven through many projects with Oxigen and through work in the UK and in the United States. James is focused on exploring contemporary design and new ways of achieving design solutions.

James also teaches landscape architecture and urban design. He is appointed as an industry professor in the School of Architecture and Built Environment at the University of Adelaide.
