A method is provided for operating a power plant, having a waste heat-generating gas turbine unit and also rooms which are to be air conditioned. Waste heat, which is discharged directly to the outside of the gas turbine unit, is used for heating the rooms which are to be air conditioned. A gas turbine for carrying out the method is also provided.

1. A method for operating a power plant, comprising a waste heat-generating gas turbine unit and rooms to be air conditioned, the method comprising: using waste heat, which is discharged directly to an exterior of the waste heat-generating gas turbine unit, to heat the rooms which are to be air conditioned;wherein the waste heat-generating gas turbine unit is covered by a plurality of enclosures, the plurality of enclosures including a diffuser enclosure, a generator enclosure, and a gas turbine enclosure, in which the waste heat, which is discharged directly to the exterior of the waste heat-generating gas turbine unit accumulates thereby heating air in the plurality of enclosures, and wherein the waste heat which is used for heating is provided by a heat exchange of heat from the air heated in the diffuser enclosure and/or in the generator enclosure; andwherein the waste heat-generating gas turbine unit comprises a gas turbine, a diffuser arranged at a hot gas exit of the gas turbine, and a generator driven by the gas turbine. 2. The method as claimed in claim 1, wherein the waste heat which is used for heating is discharged by air-to-air heat exchangers in at least one of the plurality of enclosures. 3. A method for operating a power plant comprising a waste heat-generating gas turbine unit and rooms to be air conditioned, the method comprising: using waste heat, which is discharged directly to an exterior of the waste heat-generating gas turbine unit, to heat the rooms which are to be air conditioned;wherein the waste heat-generating gas turbine unit comprises a gas turbine, a diffuser arranged at a hot gas exit of the gas turbine, and a generator driven by the gas turbine, which are each covered by associated enclosures, the associated enclosures including a gas turbine enclosure, a diffuser enclosure, and a generator enclosure, in which the waste heat accumulates thereby heating air in the associated enclosures, and the waste heat which is used for heating is discharged by air-to-air heat exchangers ace arranged in the gas turbine enclosure. 4. A method for operating a power plant comprising a waste heat-generating gas turbine unit and rooms to be air conditioned, the method comprising: using waste heat, which is discharged directly to an exterior of the waste heat-generating gas turbine unit, to heat the rooms which are to be air conditioned;covering the waste heat-generating gas turbine unit with a plurality of enclosures, in which the waste heat which is discharged directly to the exterior of the waste heat-generating gas turbine unit accumulates thereby heating air in the plurality of enclosures, and wherein the waste heat which is used for heating is provided by a heat exchange of heat from the air heated in at least one of the plurality of enclosures; andproviding blowers for air mass flows for the heat exchange of the heat from the air heated in the at least one of the plurality of enclosures or for operating air-to-air heat exchangers in the at least one of the plurality of enclosures. 5. The method as claimed in claim 4, wherein the air mass flows which are provided by the blowers are open or closed loop controlled by a control unit. 6. The method as claimed in claim 5, wherein the blowers are driven by frequency-controlled motors. 7. A method for operating a power plant comprising a waste heat-generating gas turbine unit and rooms to be air conditioned, the method comprising: using waste heat, which is discharged directly to an exterior of the waste heat-generating gas turbine unit, to heat the rooms which are to be air conditioned, and wherein the waste heat-generating gas turbine unit is covered by at least one enclosure, in which the waste heat accumulates thereby heating air in the at least one enclosure;wherein some of the waste heat of the gas turbine unit is utilized for heating the rooms which are to be air conditioned by a heat exchange of heat from the air heated in the at least one enclosure and the remainder, which is not utilized, is discharged to an exterior environment; andwherein proportions of the utilized and non-utilized waste heat are varied via controlled flaps, and the utilization of the waste heat is open or closed loop controlled via a position of the controlled flaps. 8. A gas turbine unit for implementing a method for operating a power plant, comprising: a waste heat-generating gas turbine unit and rooms to be air conditioned, the method comprising: using waste heat, which is discharged directly to an exterior of the waste heat-generating gas turbine unit, to heat the rooms which are to be air conditioned, wherein the waste heat-generating gas turbine unit is covered by a plurality of enclosures, in which the waste heat accumulates, and wherein waste heat dischargers are provided to discharge waste heat with exhaust air from the plurality of enclosures into the rooms which are to be heated; andwherein the waste heat dischargers include blowers which are connected to a control unit. 9. The gas turbine unit as claimed in claim 8, wherein the waste heat dischargers comprise air guides, by which the exhaust air from an enclosure of the plurality of enclosures can be selectively diverted into an exterior environment or into the rooms which are to be heated. 10. The gas turbine unit as claimed in claim 8, wherein the waste heat dischargers comprise air-to-air heat exchangers, arranged in an enclosure of the plurality of enclosures, and wherein outlets are selectively connected to an exterior environment or to the rooms which are to be heated. 11. The method as claimed in claim 7, comprising: switching between utilization for heating the rooms, which are to be air conditioned, and non-utilization of the waste heat, which is discharged to the exterior environment, andwherein the utilization of the waste heat is carried out in an interval-controlled or interval-regulated manner.
