Abstract: The study investigates the impact of occupant overrides on the energy and daylight performance of an adaptive blind control strategy. Firstly, experimental data is collected in a controlled office environment where occupants are exposed to manual and automated control scenarios. Secondly, results from a calibrated energy model of the same office environment are used to predict the energy and daylight performance of both scenarios. Actual and predicted energy performance are then compared to evaluate the impact of occupant behaviour on energy and daylight performance. The results indicate that occupant behaviour (OB) in respect to blind operation has an impact on the predicted performance of an adaptive facade control strategy. Hence, they confirm the need for new models that can adequately describe the influence of OB on adaptive facade control strategies.
