Abstract
District Heating and Cooling system (DHC) is an efficient energy system as they can supply chilled and heating water/steam effectively by integrating heating and cooling demand of neighboring buildings. However, there is possibility for further improvement of energy efficiency by integrated operation of adjacent DHC and utilizing waste heat from municipal incinerators and CHPs. In this study, the effect of such flexible use of heat and electricity in integrated DHC systems is examined. The main object is to raise total thermal efficiency and reduce CO 2 emission. The results of the study showed significant reduction of primary energy consumption and CO 2 emission by 12 to 36%. In addition, various side contributions to urban environment and city function were suggested such as mitigation of urban heat island, improvement of business continuity plan (BCP), electric-load leveling and improvement of city landscape.
