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; and 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.
