District Heating and Cooling system (DHC) is an efficient energy system as they can supply chilled andheating 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 ofadjacent DHC and utilizing waste heat from municipal incinerators and CHPs. In this study, the effect ofsuch flexible use of heat and electricity in integrated DHC systems is examined. The main object is toraise total thermal efficiency and reduce CO2 emission.
