Proper design of daylighting and electric lighting is of high relevance during the design of a building, affecting both, energy consumption and people’s well-being and health. To be able to assess the impact of different solutions, planners use simulation tools to evaluate the relevant performance indicators. Two reference simulation models are presented – one group office and one factory hall – that are used to describe and compare various lighting simulation tools, including widely used professional software as well as new research tools. Both models are set up including the required information for integrated daylighting and electric lighting simulation and include full spectral characteristics to also allow evaluating non-visual effects. Background information and a detailed description of the models are provided, and example simulation results are presented. The models provide researchers and professionals a means to test simulation tools and investigate their applicability for specific projects.
