An empirically-based approach toward user control action models in buildings

Abstract: In most buildings, occupants operate control devices such as windows, shades, luminaries, radiators, and fans to bring about desirable indoor environmental conditions. Knowledge of such user actions is crucial toward accu-rate prediction of building performance (energy use, indoor climate) and effective operation of building service sys-tems. This paper describes an effort to observe control-oriented occupant behavior in three office buildings in Austria. Thereby, user control actions as related to one or more of the building systems for ambient lighting, shading, window ventilation, and heating were monitored together with indoor and outdoor environmental parameters. The collected data is being analyzed to explore relationships between the kinds and frequency of the control actions and the magni-tude and dynamism of indoor and outdoor environmental changes. Moreover, implications of user actions for building performance (e.g. energy consumption) are studied.

Keywords: Building performance, facility management, action models, occupant behavior
