Korea is promoting the development, utilization and dissemination of new and renewable energy to cope with climate change. Efforts are being made to reduce energy use through the introduction of a geothermal heating and cooling system for the supply of renewable energy to collective residential facilities. The production of renewable energy was calculated by the operational principle of the heat pump used in geothermal heating and cooling systems. Based on the energy data surveyed for a newly built apartment complex in Busan, the renewable energy output of the geothermal cooling and heating system was calculated to be 785,618 kWh for electricity produced with thermal power generation, and 971,968 kWh for power used as nuclear or renewable energy. Introducing geothermal cooling and heating systems in collective residential facilities demonstrates that renewable energy can produce more than three times the energy supplied and can save as much energy as the production of renewable energy.
