Validation of lighting simulation program with all sky model-l

摘要

It is important to apply the natural light effectively for the energy saving of buildings. All Sky Model-L represents all sky conditions continuously from clear sky to overcast sky 1). RADIANCE is a radiosity program and highly evaluated on accuracy 2). The RADIANCE with All Sky Model-L was developed. The accuracy of the analysis flow is evaluated comparing the measurement values with the primitive rectangular scale model and the calculation values obtained through a series of analysis that combined All Sky Model-L and radiosity program. The features of the analysis accuracy are reported in this paper.
