Spatial considerations in modelling assumptions for manual lighting control in offices

Occupant behaviour has been identified as one of the reasons why predicted and measured energyperformance in office buildings often deviate. Occupant behaviour in this context is usually related to control of lights, windows, blinds, equipment, heating and cooling and this paper focuses on the control of artificial lighting in particular. It provides the start of an investigation on spatial influences on occupant controlled office lighting from the perspective of architecture in combination with psychological concepts of proxemics and territoriality. Conclusions are drawn to improve the accuracy of lighting control related building simulation modelling assumptions in early design stages.
