Abstract: While current lighting concepts and simulations mainly work with general criteria such as static presence models, organization-specific aspects are mostly not considered. These criteria have a major influence on the energy requirement. If organizational cultural aspects are available in the planning phase, such as the applicationspecific occupancy model, they could be used during simulation for a better energy mapping. The present work systematically analyses the influences of both the users’ occupancy patterns and the control strategy on the energy demand in an open-space office. The results show that occupancy in an object with high daylight availability has a significant influence on the energetic performance and related misrepresentations according to wrong assumptions may significantly reduce the accuracy of simulations.
