Samenvatting

The indoor climate is considered a common key concern within the FREM-field. The indoor climate is one of the most important factors for end-user satisfaction with the indoor environment, which in its turn influences job satisfaction and (perceived) productivity of office workers. One of the causes for the dissatisfaction with the indoor climate is the high degree of disunity of preferences according to the indoor climate conditions. Providing personal control over the indoor climate could be a solution to accommodate for the disunity and thereby reduce office workers’ dissatisfaction according to the indoor climate. However, allowing end-users to have personal control may potentially harm building performance. Therefore, a balance needs to be established.New technological developments may help to find thisbalance between allowing end-users to have a certain level of personal control and preserving or even enhancing building performance. Therefore, this research investigates the effect of (the usage of) personal control on office workers’ satisfaction and building performance. The indoor climate factors that will be taken into account are; thermal quality, air quality, daylight and artificial light. To carry out this research the following research questions have been formulated: 
MQ 1: What is the effect the usage of personal control over the indoor climate on office workers’ satisfaction with the indoor climate?
MQ 2: What is the effect of personal control over the indoor climate on building performance?
The research is a two-stage study with a mixed methods approach. To answer MQ 1, a single holistic case study is done in which a questionnaire and a building management system is used to collect data. To answer MQ 2, four semi-structured in-depth expert interviews were conducted.
