Abstract: A building control system for at least one building. The building control system has a system controller and at least one building operation device with a respective operation controller. Electrical supply power is fed from a supply grid to the at least one building operation device. The system controller is set up to temporarily adapt a setpoint value for each building operation parameter in order to adapt the electrical supply power to the state of the supply grid and to stabilize the supply grid. The direct specification of a temporarily modified setpoint value for a building operation parameter is a simple and efficient option of integrating the subordinate open-loop or closed-loop controllers of the building operation devices into the building control system. This measure also makes simple retrofitting possible.

Abstract: An apparatus and a method for ascertaining and billing for a volume of air generated by an air-conveying device. The air quantity ascertaining and billing apparatus has an air-conveying device generating an air volume flow through an air passage. A measuring device measures air-related parameters of the particular air volume flow. An analysis unit analyzes the measured parameters, in order to determine the total air volume that was conveyed by the air conveying device through the air passage over a period. A transfer device transfers the value determined for the air volume by the analysis unit to a validation device. The validation device links the air volume flow or the determined air volume to an economic value, in order to obtain a billing value for the generated air volume.
