PURPOSE: A method for calculating branched flow amount of a distributor using differential pressure is provided to activate an introduction of a building energy management system and to save energy consumption. CONSTITUTION: A method for calculating branched flow rate of a distributor using differential pressure is as follows. A flow meter is installed in a return side or a supply side of a main pipe of a distributor. A pressure sensor is installed in a main pipe of a distributor of a return side. The pressure sensors are installed in each branching system of a supply side. Flow sensors are installed in each branching system of a distributor for confirming hydraulic properties per each branching system of the distributor at an early stage. Measurement values of the flow sensor and pressure sensor are read after penetrating thermal mediums through per each branching system. The measurement values are obtained by changing loads of calories because flow rate values and pressure values are changed depending on calorie demands of each branching system. Data is obtained so that differences of a pressure value measured in the main pipe of the distributor of the return side and pressure values measured per each branching system of the distributor of the supply side are various.
