The impact of glazing selection on daylighting and energy performance for an office building in Canberra

An analysis is presented of the impact of glazing selection on building performance and daylight levels for a small office building designed to be built in Canberra, Australia.  Thermal modelling was carried out at the request of the client in order to optimise the glazing from a greenhouse gas emissions viewpoint. This paper presents the results of this thermal modelling.  A daylight model was not used at the time.  However, such a model was developed for this paper to examine the effects of glazing selection on natural lighting as well as the inclusion of light shelves as an alternative to tinted glass for solar control.
