User status- and user behavior-based control system and method for building technology systems and components

A method for controlling a building technology functional unit by a building technology control system, the building technology control system comprising (i) at least one interface unit that functionally couples to the building technology functional unit and (ii) a user status determination device that communicates with the at least one interface unit, the method comprising:

• (a) the user status determination device determining a current central electrical energy consumption of a building or building section having multiple electrical devices;
• (b) the user status determination device deriving, from at least the current central electrical energy consumption, a current building user status indicating whether or not a building user is currently active in the building by (i) the user status determination device finding patterns in the current central electrical energy consumption of the building or building section having multiple electrical devices, wherein the determined current central electrical energy consumption corresponds to the total current electrical energy consumed by the multiple electrical devices, which patterns are characteristic of different electrical devices, (ii) the user status determination device determining from the patterns in the current central electrical energy consumption which of the multiple electrical devices are currently activated, and (iii) the user status determination device deriving the current building user status depending on which electrical devices are determined to be currently activated;
• and
• (c) the building technology control system using the determined current building user status to determine a control specification for a building technology functional unit, wherein:
• the building technology control system uses the control specification for the building technology functional unit to control operation of the building functional unit via the at least one interface unit;
• and
• the user status determination device of the building technology control system controls the building technology functional unit as a function of which of the multiple electrical devices are identified in the current central electrical energy consumption as being currently activated.
