AN ENERGY MANAGEMENT SYSTEM FOR A BUILDING

The present invention discloses an energy management system for a building to effectively minimize total energy consumption in a building based on occupancy status thereof. Said energy management system comprising a plurality of sensors to determine occupancy status of said plurality of rooms; and an energy saving controller (100) includes a microcontroller module (101) directly connected with a transceiver module (102) to receive signals from the plurality of sensors. and a relay (103) operatively coupled with the microcontroller to control at least one power supply in the building based on processed data received from the microcontroller module (101).
