Abstract: This paper presents a new modeling routine for an integral evaluation of complex fenestration systems (CFS) using the simulation tools TRNSYS and RADIANCE. Artlight 2.0 adds the novel capability in TRNSYS to use the well-established three-phase method (3PM) from RADIANCE, which has been fully implemented in a new stand-alone TRNSYS-Type model (Type265). The improvement on existing state-of-the-art routines lies in a timestep-based communication between the thermal and daylight simulation throughout the simulation, while enabling an efficient runtime due to an improved implementation strategy. This work describes the new model in detail and presents comparison results with other tools. Model setup and functionality are demonstrated by a simulation case study including different façade settings and blind systems.
