The occurrence of the energy crisis and the increase of pollutants, followed by the exhaustion of fossil resources in the world, is one of the important issues in the field of energy, which has drawn attention to renewable energy. The building sector is one of the most energy-intensive sectors that plays an important role in the production of pollutants. The purpose of writing this thesis is to present an alternative plan to reduce fossil energy consumption in residential buildings. Considering the high potential of renewable energy sources, especially ground source heat energy in Damavand city, the combination of two sources of ground source and solar energy in order to supply the energy needed by residential buildings can lead to the realization of this goal. Due to the high efficiency and reliability of ground source heat pump (GSHP), the use of this system is increasing in the world. Therefore, it can be used as a suitable alternative to fossil fuels to meet the needs of residential buildings. In this thesis, it has been tried to present and compare three scenarios, the first scenario includes the reference building, the second scenario includes ground source heat pump (GSHP), and the third scenario includes ground source heat pump and building integrated photovoltaics (BIPV) along with the solar collector, to meet the needs of the building, which includes the provision of domestic hot water, heating, cooling, and electricity production for sale to the utility grid. The simulation was done in TRNSYS software, which is a powerful tool in the field of simulation of new energy systems (such as renewable energy). By comparing the proposed scenarios from an energy point of view, the results indicate a reduction in energy consumption in the second and third scenarios, by 2% and 26%, respectively, compared to the first scenario; And from an economic point of view, the value of net present value (NPV) in the third scenario is 18.8% and 14.1% higher than the net present value of the first and second scenarios, respectively. The return on investment (ROI) of the second scenario is 7 years; While this number shows 8 years for the first scenario and the third scenario. Also, from an environmental point of view, the second and third scenarios have led to a reduction of 11% and 41% of emitted carbon dioxide, respectively.
