Energy management system for a building and method for managing energy

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 for providing electrical energy,
• at least one electrical energy storage 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,
• at least one third state of charge analyser for determining the state of charge of the at least one electrical energy storage device, and
• a controller configured to control an operation of the at least one heat pump, the at least one first thermal energy storage device, the at least one second thermal energy storage device, the at least one electrical energy storage device and the at least one renewable energy generation device,
• wherein the controller is configured to determine a state of charge of the at least one electrical energy storage device based on information of the at least one third state of charge analyser, and
• wherein the controller is configured to control a charging and/or a discharging of the at least one electrical energy storage device based on a determined a state of charge of the at least one electrical energy storage device.
