Air conditioning control system

Abstract

According to an embodiment, provided is an air conditioning control system having a remote controller which collectively controls air conditioning facilities respectively provided in multiple buildings through a network. A building monitoring and controlling device is provided in each of the buildings. The building monitoring and controlling device monitors an air conditioning facility in a building where the building monitoring and controlling device itself is installed, and transmits operation data on the air conditioning facility to the remote controller. The remote controller calculates each operation setting value based on each set of operation data, and transmits the calculated operation setting value to the building monitoring and controlling device corresponding to the calculated operation setting value. The building monitoring and controlling device which has received the operation setting value controls the air conditioning facility by transmitting the operation setting value to the air conditioning facility.
