An energy management method for an energy system in a building, wherein the energy system comprises: a plurality of non-controllable energy consumers, at least one controllable energy consumer, an energy storage, a mains connection point via which energy can be obtained from a mains and/or fed into the mains, and a regulation or control device which is configured to regulate or control said at least one controllable energy consumer and said energy storage, wherein said plurality of non-controllable energy consumers is configured to obtain energy from the mains or from said energy storage, and wherein the method comprises the following steps which are cyclically performed at a distance of intervals (ΔT2): acquiring a current state of charge (SOC act) of said energy storage; setting a period of time (ΔT 0) during which said non-controllable energy consumers are supplied with energy from said energy storage; determining a limit value (SOC high) of the state of charge of said energy storage depending on a determined or estimated energy demand of said plurality of non-controllable energy consumers during said set period of time (ΔT 0) and depending on a point of time within said set period of time (ΔT 0); operating said at least one controllable energy consumer with energy from said energy storage if the current state of charge (SOC act) of said energy storage is greater than said determined limit value (SOC high) of the state of charge; and operating said at least one controllable energy consumer with energy from the mains if the current state of charge (SOC act) of said energy storage is less than or equal to said determined limit value (SOC high) of the state of charge. a plurality of non-controllable energy consumers, at least one controllable energy consumer, an energy storage, a mains connection point via which energy can be obtained from a mains and/or fed into the mains, and a regulation or control device which is configured to regulate or control said at least one controllable energy consumer and said energy storage, wherein said plurality of non-controllable energy consumers is configured to obtain energy from the mains or from said energy storage, and wherein the method comprises the following steps which are cyclically performed at a distance of intervals (ΔT2): acquiring a current state of charge (SOC act) of said energy storage; setting a period of time (ΔT 0) during which said non-controllable energy consumers are supplied with energy from said energy storage; determining a limit value (SOC high) of the state of charge of said energy storage depending on a determined or estimated energy demand of said plurality of non-controllable energy consumers during said set period of time (ΔT 0) and depending on a point of time within said set period of time (ΔT 0); operating said at least one controllable energy consumer with energy from said energy storage if the current state of charge (SOC act) of said energy storage is greater than said determined limit value (SOC high) of the state of charge; and operating said at least one controllable energy consumer with energy from the mains if the current state of charge (SOC act) of said energy storage is less than or equal to said determined limit value (SOC high) of the state of charge. acquiring a current state of charge (SOC act) of said energy storage; setting a period of time (ΔT 0) during which said non-controllable energy consumers are supplied with energy from said energy storage; determining a limit value (SOC high) of the state of charge of said energy storage depending on a determined or estimated energy demand of said plurality of non-controllable energy consumers during said set period of time (ΔT 0) and depending on a point of time within said set period of time (ΔT 0); operating said at least one controllable energy consumer with energy from said energy storage if the current state of charge (SOC act) of said energy storage is greater than said determined limit value (SOC high) of the state of charge; and operating said at least one controllable energy consumer with energy from the mains if the current state of charge (SOC act) of said energy storage is less than or equal to said determined limit value (SOC high) of the state of charge.
