Abstract: Tubular daylighting devices (TDDs) and daylighting shelves are two methods for bringing natural exterior daylight into the hard-to-reach, interior spaces of a building. Recently two models to simulate these devices were added to the EnergyPlus whole-building energy analysis program. In addition to modeling their daylighting effects, solar gains and conductive/ convective heat transfer are also integrated into the zone heat balance. This paper presents an overview of the concepts and algorithms implemented in EnergyPlus to simulate TDDs and daylighting shelves. Preliminary testing efforts are also described.
