ENERGY MANAGEMENT SYSTEM FOR A BUILDING AND METHOD OF USING THE ENERGY MANAGEMENT SYSTEM

The present invention relates to an energy management system for a building, comprising at least one heat pump, at least one first thermal energy storage device for providing domestic hot water, at least one second thermal energy storage device for providing space heating, at least one renewable energy generation device, at least one first state of charge analyser for determining the state of charge of the at least one first thermal energy storage device, at least one second state of charge analyser for determining the state of charge of the at least one second thermal energy storage device, and a controller configured to control the at least one heat pump, the at least one first thermal energy storage device, the at least one second thermal energy storage device, and the at least one renewable energy generation device. The controller is configured to control, in dependence on at least the state of charge of the at least one first thermal energy storage device and/or the state of charge of the at least one second thermal energy storage device, whether one of and which of the at least one first thermal energy storage device and the at least one second thermal energy storage device is charged with energy provided by (a heat pump operation of) the at least one heat pump and/or energy provided by the at least one renewable energy generation device. Furthermore, the present invention relates to a method of using the energy management system.
