ABSTRACT: There are a number of tools currently used by architects for the investigation of solar
penetration in buildings. However, complex building forms present unique analysis difficulties. Current
3D computer aided design software can display sun patches and shadow on the exterior of buildings,
however, it is difficult to obtain accurate and timely information about the sun patches internal to the
building. This paper details a methodology to enhance the capability of commonly used CAD software
to show indoor sun patches in complex buildings. The paper demonstrates how multiple software
packages, including the Radiance Lighting Simulation Suite, can be used as part of a tool chain to
display solar penetration in complex buildings in a timely manner.
