Installation of BMS - can minimize energy consumption and maximize indoor comfort. A fully optimized BMS can save energy costs to the extent of 15% - 20% as compared to a building without a BMS [36]. Additional a thermostatic valve for each radiator and a radiant temperature sensor mounted per radiator were required for BMS. Weather sensor, space temperature sensor, CO2 sensor, heat meter, damper actuator and control devices were proposed to be installed.
