Summary

The aim of this paper is to analyze the energy, environmental, and economic benefits of the installation of ground source heat pump systems in residential buildings in Cyprus. Two typical reference buildings, a single-family and a multi-family one, have been designed for this purpose and the heating and cooling energy demands are calculated with the aid of EnergyPlus software for five representative locations on an hourly basis. The results are translated in primary energy consumption assuming two different conventional systems for heating, an LPG- and an oil-fired boiler, as well as an air-to-air split type heat pump for cooling. The same energy demands are assumed to be covered by a ground source heat pump system, which consists of a vertical ground heat exchanger and water-to-water heat pumps. The ground source heat pump system is dimensioned with the aid of EED 3.16 software and analyzed using an in house developed and validated code; as a result the primary energy consumption is calculated. Furthermore and based on the primary energy consumption, the CO2 emissions of the alternative systems are calculated and compared. Finally the financial analysis of the alternative systems is performed using the net present value index. The results prove that significant energy and economic benefits can be achieved by the substitution of conventional heating and cooling systems with geothermal heat pumps on the residential sector of Cyprus. Conversely, the environmental benefit is eliminated as the ground source heat pump systems emit more CO2 than the alternative common ones.
