In designing a building, technical planning such as mechanical and Electrical planning is needed, which includes air planning. The purposes of this research is to find out how much electricity consumption is used by the VRV system and the Chiller system, so we get also an estimate of the electricity costs that need to be incurred during the system use. To find out how much electricity consumption is expended by the system, it is necessary to know the capacity of the room’s cooling requirements along with the electrical power of the system, the data is obtained from the research site, product catalog, and supporting journals so that it can be simulated electrical energy consumption. The results of this study indicate the specifications and material or system components used, the simulation of the electrical energy consumption of the system, the electricity cost of the system, and the comparison of the electricity costs of the two systems namely the VRV system and the chiller system.
