Description: In order to save power, the researching group of Bui Thai Luan, Tran Ngọc Quy and Le Truong Phu focused on lighting and air-conditioning systems which are most electricity consumption in  the schools. The researching group proposed replacement a new type of power savings lamp, mount the sensor in the classroom to count the number of students attending school in order to turn on the priority lamp ranges close to the podium. The lamps are lighting on corridors are managed in the real-time system, turned on at 6 pm and off at 6 am, avoiding all day wasteful lighting. For air conditioning, power switches are integrated into the door lock to avoid situation of turn on air-conditioner when nobody in the room.
