Combined Cooling Heating and Power (CCHP) can be applied to energy management system in buildings to increase the efficiency of primary energy consumption, as well as to reduce the carbon dioxide emission. This thesis proposes an algorithm to determine optimal hourly scheduling of the CCHP system for building load. Heat storage tank and photovoltaic system are also incorporated into energy management system. The objective function is to minimize total operating costs with the constrains of equipment operating limits and energy balance conditions. The formulated problem is solved by the Linear Programming. The determined operating conditions are displayed on the Graphic User Interface (GUI) to assist the operator to operate such system. Performance verification of the proposed building energy management has been done using power demand of one shopping complex. The results show that the total cost of electrical and cooling energy decreases by 12% per year, and increase to 40% when additional income from selling the surplus cooling water is considered.
