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.
The spectral output of a light source has profound impact on both the colour quality and energy efficiency of the resulting illumination. Traditionally, white light has been used to illuminate objects of all colours. The aim of our research is to investigate a radical new approach to lighting that could substantially reduce the energy wasted by absorption.
Lighting products that use newer technologies can emit virtually any pattern of light throughout architectural spaces. However, fundamental research is needed to determine how to best capitalise on this. We are investigating the relationships between the spatial distribution of light and visual interest, as well as the appearance of the size of architectural spaces.

Many new lighting technologies are controlled by digital signals that customise a wide range of attributes (eg, colour, brightness, spatial distribution). Research is needed to understand how people conceive these light properties and what variables effect interaction with illumination. We are currently investigating the effect of control resolution (the smallest change possible) on user efficacy, accuracy, and satisfaction, as well as energy consumption.
