Exploring ways to inform the design of better buildings is the thesis of Edward's research efforts.

Hong Kong is the world's most energy efficient city (according to a report by the Economist). It provides a unique 'laboratory' for the study of environmental issues of compact and high-density living. Apart from the need to understand the physics of the built environment, it is also important to investigate into the psychological and sociological aspects of living as well as the cultural and contextual factors of environmental behaviours.  Since arriving at CUHK, Edward has directed his research focus to designing better naturally lit and ventilated buildings in high density urban conditions. To achieve that, Edward has initiated a number of strategic research projects ranging from collecting fundamental weather and daylight data (with the IDMP station and the ‘dog’ houses), developing computational algorithms, tools and design methods, establishing standards, conducting user surveys and on-site measurements, developing and testing design prototypes, and forming alliance and joint educational and design projects with the school and housing sectors.

Whilst some research activities are scientifically focused, others are closely related to design activities. It is Edward's tradition to host focused design studios during term breaks with selected groups of students. Recently, the design of high rise residential buildings, an open design competition organised by Hong Kong Housing Authority, has been the vehicle for such a studio. Edward calls it: Active Studio. It is through design that research questions could be formulated, ideas and hypotheses could be tested and tools could be validated. Quoting Professor Dean U Hawkes (Edward's PhD Supervisor): Theory is the body of principles which explains and interrelates all the facts of a discipline. Critical Practice is the tool by which theory is advanced. Without theory and critical practice teaching (and research) can have no direction and no cutting edge.  As to how research should be conducted, quoting Alexander Todd (Nobel Laureate 1957), research is like playing golf, "Just keep your head down, and your eyes on the ball".
