The recently-proposed Dynamic Daylight Simulation file format (DDS) aims at standardizing daylight coefficient output from lighting simulation software, such as Radiance. This revision provides an opportunity to reexamine how daylight coefficients are effectively used within a simulation context, either for estimating annual daylight autonomy profiles, mapping luminance distributions for glare assessments, or predicting total energy savings from automated daylighting controls via integrated thermal/lighting simulation. A new module is proposed to read in DDS files, and fold the daylight coefficients at run-time with the all-weather Perez sky model and annual weather data. This DDS module can be accessed directly at run-time by whole-building energy simulation programs such as ESP-r or, for the typical Radiance user, in a 'standalone' way from the command line to produce, for instance, annual daylight autonomy profiles. Additional module functionality includes its expandability, e.g. boundless number of sensor points and daylight sources, making the module as useful for visualization purposes as for integrated thermal/lighting simulations. The presentation concludes on how the module is used within ESP-r along with SHOCC; another simulation module which considers occupant-related use of personal controls in thermal/lighting simulation.
