Abstract: An entirely new method to model the interaction of objects exposed to solar radiation is presented. The method has primarily been developed to model solar gains of shaded and unshaded glazing components, but is also well suited to model energy flows related to the absorption of opaque surfaces or solar collectors. The method relies on a specially developed physically-based, multi-chromatic, forward Monte-Carlo raytracing algorithm. Though based on fundamental principles of optics and electrodynamics, the method can be used to perform practical building science simulations with hitherto unattainable accuracy. An overview of the method as well as a practical application case is presented here.
