Regional　integrated　heating　using　renewable　energy　is　an　efficient　way　to　achieve　the　target　of　carbon　emission　reduction.　Based　on　geothermal　sources,　air　source　heat　pumps,　and　inter-seasonal　energy　storage　technologies,　a　multi-source　integrated　regional　heating　system　is　proposed,　which　can　meet　the　requirement　of　heating　in　buildings.　With　a　residential　community　with　an　area　of　35700　m2　as　the　study　case,　the　models　of　geothermal　source　heat　pump　and　air　source　heat　pumps　are　constructed.　Next,　the　energy　performance　and　environmental　performance　of　the　integrated　district　heating　system　are　analyzed.　The　study　manifests　that　the　multi-source　central　heating　system　reduces　the　energy　consumption　by　45.73%　in　comparison　with　the　tranditional　boiler　solution,　and　the　CO2　emission　is　reduced　by　787.83　tCO2.　The　multi-source　heat　pump　system　can　achieve　social　benefits,　with　the　help　of　reasonable　dispatching　between　the　source　and　load　sides,　and　the　contribution　of　renewable　energy.　The　long-term　stable　operation　of　the　energy　system　can　be　achieved.　The　study　provides　a　theoretical　reference　for　the　application　of　the　conventional　energy　systems　combined　with　geothermal　energy.　©　Published　under　licence　by　IOP　Publishing　Ltd.
