DEVELOPMENT OF ANALYSIS SOFTWARE FOR THE OPTICAL CHARACTERISTICS AND DAYLIGHTING PERFORMANCE OF CONVENTIONAL AND TUBULAR SKYLIGHTS

Abdelaziz Laouadi, Morad Atif

Abstract: This paper presents an overview of the development of analysis software for the optical characteristics and daylighting performance of conventional and tubular skylights. The software is useful to skylight manufacturers, building designers and fenestration rating councils. The software development process spans over a four-year period, and includes development of prediction models for optical and daylighting performance of different skylight shapes, experimental and analytical validation of the prediction models, and software design. This paper focuses on the software structure, inputs, outputs and analysis modules. Preliminary results from the prediction models are also shown for the beam transmittance of barrel vault skylights, diffuse transmittance of domed skylights under different sky conditions, and average Daylight Factor on internal room surfaces.
