Lighting Simulation for Architectural Design: a Case Study
Anna Pellegrino, Luca Caneparo · eCAADe proceedings · 1996
The paper considers some of the lighting simulation instruments at present available to architects for lighting design. We study the usability and accuracy of various systems, scale models, numerical simulations, rendering programs. An already built environment is the reference comparison for the accuracy of the simulation systems. The accuracy of the systems is evaluated for respectively quantitative simulation and qualitative visualisation. Quantitatively, the programs compute photometric values in physical units in a discrete number of points of the environment. Qualitatively, the programs generate images of visible radiation comparable to photographs of the real environment. They combine calculations with computer graphics, that is, they translate numerical values into images.
