The present invention relates to an energy management method for an energy system () in a building. The energy system () comprises a plurality of uncontrollable energy consumers (HH), at least one controllable energy consumer (WP), an energy storage device (BAT), a net connection point (NAP) through which energy can be drawn from the net and/or fed into the net, and a feedback-control or control device (EMS) which is designed to feedback-control or control the at least one controllable energy consumer (WP) and the energy storage device (BAT). The plurality of uncontrollable energy consumers (HH) is configured to draw energy from the net or from the energy storage device (BAT). The method comprises the following steps: detecting a current state of charge (SOC) of the energy store device (BAT), defining a period of time (&#x394;T) during which the uncontrollable energy consumers (HH) are supplied with energy from the energy storage device, determining a limit value (SOC) of the state of charge of the energy storage device (BAT) on the basis of a determined minimum energy demand of the plurality of uncontrollable energy consumers (HH) up to the time of charging (T), operating the at least one controllable energy consumer (WP) with energy from the energy storage device (BAT) if the current charge state (SOC) of the energy storage device (BAT) is greater than the determined limit value (SOC) of the charge state and operating the at least one controllable energy consumer (WP) with energy from the net if the current charge state (SOC) of the energy storage device (BAT) is less than or equal to the determined limit value (SOC) of the charge state.
