Professor Richard de Dear


Professor in Building Science
Research Director, Architectural Science
IEQ Lab Director

Over the last three decades, Professor Richard de Dear has built a career in the area of human thermal comfort. He has published over 300 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 several thousand citations within the indoor environmental literature. De Dear and Brager's adaptive model underpins the American Society of Heating and the Refrigerating and Air Conditioning Engineers thermal comfort standard (2004, 2010, 2013), and and has informed several other national and international standards/codes, including the Netherlands, Europe (CEN), China and most recently, India. Countless green buildings around the world have been engineered on the basis of the adaptive comfort model, and every year de Dear receives several keynote lecture and visiting professor invitations from conferences or universities especially across the Asia (including China, Japan, India, Korea, Hong Kong amongst others), where his adaptive comfort model has had its greatest uptake.

Daniel Castro


MPhil Candidate

Daniel Castro’s is concerned about noise propagation within enclosed spaces. The acoustic properties of building materials play a significant role on how sound is perceived in rooms. For this reason it is relevant to know how the acoustic material properties can be measured, and what methods are available to predict the behavior of acoustic panels at design stage. Daniel’s research proposal aims to develop a methodology to obtain the in-situ absorption coefficients of a room by using a combination of inverse noise modelling and boundary element method (BEM). In addition, this methodology could be also used to predict the acoustic impedance of acoustic panels with irregular perforations.

PhD Candidate
Alp has a B.Sc. in electrical engineering from Istanbul Technical University (Turkey) and M.Sc. in architectural lighting design from KTH Royal Institute of Technology (Sweden). His professional experience includes project engineering, architectural lighting and luminaire design.

Alp’s doctoral research investigates ways to reduce the energy consumed by lighting by optimising the spectral power distribution of illumination for object reflectance. Using computational simulations and human experiments, this research will enable the design of advanced lighting systems that detect object colours and project dynamic and customized light spectra.




Bettina Easton


PhD Candidate
