Abstract

A great amount of global energy is consumed for building heating and cooling. Renewable energies are considered to prevent pollution made by fossil fuel in the building industry. Ground source heat pumps are known as a technology to supply heating and cooling demand in buildings. In this paper, the energy demand for residential cooling and heating is calculated in Iran in 2030. Then, two scenarios are discussed to supply the needed energy. In the first scenario, the energy is supplied by air source heat pumps (split units), and the second scenario considered ground source heat pumps. The result indicates that not only the second scenario can cause 8736.7 million cubic meters of natural gas and prevent 59.6 million tonnes of air pollutants, but also the country can export 7028 million $ electricity to its neighbors. Also, the to tal cost for the country to supply the energy need is reduced by 49994 million dollars.
