My primary research interest is understanding the complex interrelationship among climate (and change), energy (demand and planning), built environment (building physics) and society (users and economy) – as applied to design and operation of the built environment – through the application of simulation and computational intelligence techniques. In my research in the past few years, I have been focusing on long-horizon energy-environment-economic modelling, the quantification of scenarios and pathways, and interdisciplinary issues in energy economics and policy. I am also interested in the performance-based design of low– and zero–carbon buildings, and their constituent energy and environmental systems.
