The disclosure relates to a method for controlling heat transfer between a local cooling system and a local heating system, the method comprising: determining a local energyconsumption need (LCC1, LCC2) of the local cooling system; determining a local energy consumption need (LHC1, LHC2) of the local heating system; controlling, based on the local energy consumption need (LCC1, LCC2) of the local cooling system and the local energy consumption need (LHC1, LHC2) of the local heating system, a heat pump (50, 50′) connected between the local cooling system and the local heating system and configured to transfer heat from the local cooling system to the local heating system.
