eothermal heat pumps (GSHPs), or direct expansion (DX) ground source heat pumps, are a highly efficient renewable energy
technology, which uses the earth, groundwater or surface water as a heat source when operating in heating mode or as a
heat sink when operating in a cooling mode. It is receiving increasing interest because of its potential to decrease primary energy
consumption and thus reduce emissions of the greenhouse gases (GHGs). The main concept of this technology is that it uses
the lower temperature of the ground (approximately <32°C), which remains relatively stable throughout the year, to provide space
heating, cooling and domestic hot water inside the building area. The main goal of this study was to stimulate the uptake of
the GSHPs. Recent attempts to stimulate alternative energy sources for heating and cooling of buildings have emphasised the
utilisation of the ambient energy from ground source and other renewable energy sources. The purpose of this study, however,
was to examine the means of reducing of energy consumption in buildings, identifying GSHPs as an environmental friendly
technology able to provide efficient utilisation of energy in the buildings sector, promoting the use of GSHPs applications as an
optimum means of heating and cooling, and presenting typical applications and recent advances of the DX GSHPs. The study
highlighted the potential energy saving that could be achieved through the use of ground energy sources. It also focused on the
optimisation and improvement of the operation conditions of the heat cycle and performance of the DX GSHP. It is concluded that
the direct expansion of the GSHP, combined with the ground heat exchanger in foundation piles and the seasonal thermal energy
storage from solar thermal collectors, is extendable to more comprehensive applications.
