Our research program concentrates on the ways and environments in which light can be applied. We are developing ideas about how future technologies can be leveraged to maximise the use of light in a wide variety of contexts and settings. We question current lighting design practices to develop innovative, sometimes fundamentally new, ways of using lighting in architectural spaces.
Our experiments investigate the impacts of these applications on the experience of architecture and on energy consumption. Our projects revolve around three research focus areas: the spectrum of illumination, the spatial distribution of light, and user control of lighting.
This laboratory investigates architectural lighting applications. Research projects simultaneously answer fundamental questions about the relationship between lighting and the human experience and present innovative world-leading ideas about better ways to design with light. The research in the lab is experimental and classical psychophysical research methods are most commonly used. Other research methods (e.g., those from human-computer interaction) are integrated when appropriate.
