I am interested in the way that the technology of building relates to the external environment. This leads to studies of passive and assisted passive ventilation systems, natural light and its intersection with artificial light, heating and thermal insulation and diurnal cooling. A more intangible benefit is that through this kind of work it is possible to envisage environments where the natural world is not excluded from the built environment; where boundaries between the two worlds are ambiguous. I am also interested in the time-based aspects of architecture that relate to human occupation and building use and takes forward an early interest in cybernetics and building briefwriting. This has led to looking at the use of buildings using performance analogies, especially those developed by Bateson and Goffman. It has also led to an interest into the ways that buildings might ‘put on’ performances to entertain and enlighten their occupants.
