Daylight modelling and analysis is an important component in building design. Maximizing useful daylight while avoiding unwanted heat gains and losses requires deep understand of the physical processes in buildings. At ENSIMS we use Radiance for lighting modelling, and DaySim for climate-based daylight analysis. Our works include the optimization of fenestration designs and the solar availability of urban areas.

ENSIMS provided energy and daylight analysis in the Shadowlands article published in the CIBSE Journal (July, 2014). In this study, the Sketchup model of a high-rise building cluster in the City of London was exported to DaySim, where climate-based daylight modelling was carried out to produce the illuminance data for the visualization.
