Semantics-based Explanation of Cyber-physical Systems

Smart Building UC

Heating, ventilation and air-conditioning systems of modern energy efficient buildings are becoming increasingly complex. To keep energy consumption as low as possible it is important to control the operation of heating, ventilation and cooling systems in a way adapted to the use of the building and the current weather conditions. However, other factors such as open or closed windows and the operation of shading devices at the windows also influence the performance of a building significantly. Many buildings contain a lot of sensors whose data are used for control purposes and the sheer number of sensors are hard to manage and maintain by the building operators.

Automated control algorithms are available, but the control actions and the underlying parameters are not always transparent to both facility managers and occupants of the buildings.

Therefore, such buildings are a good use case to apply the methods developed in the project SENSE to explain events such as window blinds being closed or opened to stakeholders. Another example could be to detect windows that are left open accidently to report it to facility managers. 

To validate the use case, sensor data from a real office building will be used in cooperation with the building owner as well as simulation data from the same office building.
