A heat pump strategy to meet the simultaneous heating and cooling needs of a multifunctional office and residential building

This paper discusses control solutions for the heating needs of a multifunctional office and residential building. The building is heated by district heating and heat pumps, whose different bivalent plants are analysed. To determine these bivalent operating states, optimisation calculations were performed in terms of primary energy consumption, operating costs and CO2 emissions. In summary we can conclude the optimal operating mechanism.
