In the design of a green building with zero energy consumption, according to the annual energy consumption of the building, the source of clean energy production, such as a suitable system for using sunlight or wind, without fossil fuel pollution, can be seen. In this dissertation, the stages of designing a green building with an area of 2.98m and a cost of zero energy consumption, a hypothetical building with the characteristics and specifications of Tehran has been considered. The factors influencing the amount of heat load are identified according to the degree of importance and are considered in the design of the building. Items such as the dimensions of the building plan, materials and insulation used in the walls, windows, awnings and the amount of fresh air were examined. In this project, four different scenarios have been used in terms of building ventilation. The first scenario is the cooling water system for cooling and the gas package for heating and the second scenario is the split system for cooling and heating, which is part of the building's energy needs from the photovoltaic panel and the linear share collector and flat panel collector; And the different scenarios have been compared in terms of economy and source of electricity consumption of the building. Douroush is intended to supply electricity to the building, the first method is to sell all the electricity produced by the panels to the network and buy the electricity consumed by the building from the network, the second method is to sell the surplus electricity consumed by the network and use the battery to supply the rest of the building. The project seeks to design a building with zero annual energy costs. This process has been calculated by the Ministry of Energy for the amount of electricity purchase tariffs and the monthly and annual income of the building has been obtained. In the following, the amount and cost of solar power equipment equipment as well as solar water heater are calculated. Finally, in the current research scenario, we will have the fastest return on investment with almost 5 years in the scenario of total sales of electricity generated to the network and the use of air conditioning systems and gas package; And in the second scenario, the use of split systems for ventilation and the use of panels and batteries to supply electricity to the building is the latest return on investment of nearly 86 years.
