Abstract: The object of the invention is a control method of energy-consuming devices within a building, consisting of many kn areas with different energy demand, where each area has at least one energy-consuming device assigned, wherein a proper level of energy consumption Pw is determined on the basis of information about occupancy level N in the particular area kn and depends on occupancy level N, with a proper energy consumption level Pw1, . . . PwM within a predefined sub-period of time (t1, . . . , tM), during which the system turns on energy-consuming devices for time periods ton1, . . . , tonM, depending on the occupancy level N, in order to attain the previously determined energy consumption level Pw; having reached the previously determined energy consumption level, the system turns off energy consuming devices for periods toff1, . . . , toffM.
