As the amount of CO_2 emissions from natural gas is less that other fossil fuels, the promotion of District Heating and Cooling (DHC) using natural gas as a main fuel is one of the promising solutions to the global warming. This study focused on the natural gas powered cogeneration systems in DHC and evaluated the retrofitting plan for the efficiency improvement. An evaluation program of DHC developed by authors was validated with approximately 1% error by comparison with annual operation data from an existing plant. It was shown that the retrofitting plan would achieve the reductions of primary energy consumption and of CO_2 emission by 24% and by 16%, respectively.
