Richard de Dear, Ph.D
I obtained my PhD from the University of Queensland, Brisbane Australia under the supervision of Professor Andris Auliciems in 1985. Between 1985 and 1987 I worked as a post-doc with Professor PO Fanger at the Technical University of Denmark in Copenhagen. From 1987 until 1991 I taught in the Department of Geography at the National University of Singapore. I have been on the teaching faculty here at Sydney's Macquarie University since 1991.
Teaching
- I am currently involved in lecturing and curriculum development for these units:
- GEOS117 BIOPHYSICAL ENVIRONMENTS
This unit is a broad-ranging introduction to physical geography, with a particular focus on the biophysical environment of Sydney. It is a new subject offered by the Department of Physical Geography for the first time in 2001.
- GEOS112 PLANET EARTH
This unit is a broad-ranging introduction to earth systems science. It is organised into four modules: [1] the solid earth (lithosphere), [2] the fluid earth (atmosphere and hydrosphere), [3] the interface (surface of the earth), and [4] life processes and humans (the biosphere). I am responsible for the 2nd module.
- GEOS216 ATMOSPHERIC ENVIRONMENT
This unit is a broad introduction to the atmospheric sciences- climatology and meteorology. There are two hours of lectures and three hours of lab-work each week. GEOS216 forms a prerequisite to all 3rd year atmospheric science units (GEOS301, GEOS320, GEOS393).
- GEOS320 BIOMETEOROLOGY
This unit reviews the interdisciplinary area involving interactions between atmospheric processes and living organisms - plants, animals and humans. It concerns the process-response system of energy and matter flows within the biosphere. There are two hours of lectures and a four hour laboratory practical each week. Additionally there is a compulsory field experiment.
GEOS393 APPLIED METEOROLOGY
This unit consists of two hours of lectures and a four hour laboratory practical each week. Additionally there is a compulsory field experiment. The course's curriculum consists of three modules:
[1] acquisition and analysis of data from in situ instrumentation (temperature, psychrometrics, radiometrics, wind, dataloggers and automatic weather stations),
[2] remotely sensed data (radar, satellites) and radiosondes
[3] diverse applications including aviation, marine transport, agriculture, architecture/engineering, renewable energy and urban air quality management
- GRADUATE STUDENT RESEARCH SUPERVISION
In the general area of applied meteorology/climatology, specifically in connection with architecture, neural networks, urban air quality and air pollution, indoor climates, thermal stress/comfort and biometeorology.

Current Research Activities
My main area of research is in biometeorology, with continuing interests in other aspects of applied meteorology and climatology. A list of my recent publications may be found by clicking here.
Some recent research activities include:
- During 2000 I spent a sabbatical working with Professor PO Fanger and colleagues in the International Center for Indoor Environment and Energy at the Technical University of Denmark. Among other things I worked on ultra fine and PM2.5 particles in the atmosphere.
- Hybrid ventilation
. Buildings in the commercial sector can be designed or retrofitted with hybrid ventilation systems that utilise a natural ventilation mode whenever outdoor weather permits, and then revert to conventional air conditioning or heating systems when necessary. I have been working on thermal comfort issues related to hybrid ventilation systems in collaboration with Gail Schiller Brager, University of California at Berkeley, since 1998.
- I am a member of the Australian Research Institute for Climate, Comfort and Performance. ARICCP is a multi-institution organisation with ‘state of the art’ research facilities, including a climate chamber, located in Sydney. ARICCP comprises scientists from Sydney University, Macquarie University, CSIRO Wool Technology, University of New South Wales, and the Australian Institute of Sport, all actively researching the relationships between thermal comfort/strain on the one hand, and health, work efficiency and sport performance on the other.
- During 1997~99 I was co-investigator with Kris Cena, D.Sc (Murdoch University, Perth, Western Australia) on ASHRAE RP-921 for field studies of occupant comfort and thermal environments in a hot-arid climate (Kalgoorlie, Western Australia). In 1999 this project received a Technical Paper Award from the American Society of Heating, Refrigerating and Air-Conditioning Engineers the paper entitled "Field Study of Occupant Comfort and Office Thermal Environments in a Hot, Arid Climate." ASHRAE Transactions, V.105(2) pp. 204-217. The Final Report on ASHRAE RP-921 may be downloaded from here, Appendix A here, and Appendices B though E here (all downloads are available free but require Acrobat Reader® software which may be downloaded for free from here).
- From1996 until 98 I was PI on ASHRAE RP-884 Adaptive Models of Thermal Comfort, which aims to develop control algorithms for indoor climate that conserve energy (and reduce greenhouse gas emissions) by taking advantage of human thermal adaptive capabilities. The adaptive model for naturally ventilated premises is currently under consideration for inclusion in the latest revision of ASHRAE's Standard 55, as described in an article to be published in the October 2000 issue of the ASHRAE Journal (A standard for natural ventilation).
- During 1995 I spent a five-month sabbatical with colleagues in the Building Science Group at the Center for Environmental Design Research, University of California at Berkeley. I worked on problems of heat transfer from the human body using a thermal manikin and a wind tunnel. Whilst at Berkeley I also worked on adaptive models of thermal comfort.
- During 1995 I spent a month as Visiting Researcher in the Department of Building Services Engineering, Hong Kong Polytechnic University. My main activity there was helping to establish thermal comfort research programmes in that department.
