Use of energy performance simulation for operation cost distribution in multipurpose conventional centre

The  paper  describes  case  study  of  application  of computer simulation in the field of operational energy costs distribution in the building  with variable operation and no possibility of direct energy consumption measuring. The simulation is used to predict energy needs related to the climatic loads and to make a synergy with the internal loads. Presented results are in terms of average energy consumption related to floor area and operational case, divided into the heating, cooling and electric energy .
