      abstract     = {This study presents key findings of observed datasets in a
                      nearly zero-energy office building for over 66 working days
                      from June to mid-September in 2019, Luxembourg. Measurements
                      of indoor and outdoor environmental parameters as well as
                      user-shade override adjustments were extracted from the
                      KNX-based building management system (BMS) in 47 office
                      rooms located in three typical floor levels. Relative
                      frequency and "rate of change" of blind use were analysed in
                      terms of window orientation, occupancy level, and the time
                      of the day. Logistic regression and data mining techniques
                      were used to identify potentially useful and understandable
                      occupant behaviour patterns and reveal the main triggers
                      behind blind adjustments. The well-designed automation
                      system together with the inner glare protection formed the
                      base of very low user-shade interactions. A mean of 0.184
                      manual blind adjustments per day per office. Eight
                      regression sub-models were developed and all were incapable
                      of predicting user-shade lowering and raising events.
                      Alternatively, two user profiles were mined based on 20
                      rules gained from clustering analysis: user (ß) was
                      representing the passive user, and user (μ) the medium
                      user. Overall, we conclude that the automated shading system
                      in this building is satisfactory, user-friendly, and a
                      robust control system.},
