Abstract: Embodiments provide platforms and techniques for, modeling, simulating, and/or analyzing lighting, including daylighting, in architectural spaces. For example, lighting performance properties can be associated with structural components defined as building geometry of architectural space models, and environmental daylighting models can be formulated in association with designated geographical locations and orientations, and keytimes. A lighting rendering engine can compute lighting rendering data by ray-tracing the architectural space model as a function of the structural components, the lighting performance properties, and the environmental daylighting model at each keytime. The lighting rendering data can be used to output images can be output that graphically represent, for each keytime, a depiction of the architectural space model and a distributed lighting performance metric.
