Abstract: This paper describes the design, operation, and demonstration of the Solar Heliodon, a novel mechanical instrument developed to enable automated simulation of interior daylighting conditions with physical architectural models using the sun as a light source. An experiment involving two physical models, one with angularly-selective complex fenestration and the other with a holographic window film, is performed to illustrate the applicability of the instrument for enabling subjective and objective human-factors evaluation of optically complex daylighting design concepts. Benefits and limitations relative to contemporary computational approaches to model generation, simulation, and evaluation are discussed.
