Water, environment, food and energy are vital resources for human beings; Therefore, creating sustainable security in these interconnected resources is very important. In this research, a solution called Mini Energitic Dark Greenhouse (MEDG) is introduced and its components are described. The impact of this system on various areas of urban management is also explained. This approach can simultaneously help to increase the sustainable security of water, environment, food and energy in the framework of the water, environment, food and energy nexus in urban life. Mini Energitic Dark Greenhouse (MEDG) is used on a home scale. For this system, economic analysis has been done from two perspectives of investors and households in Tehran and costs and revenues have been calculated from these two perspectives. According to the calculations made, the cumulative profit and loss of this system at the end of each year is presented from these two perspectives. From the investor's point of view, this system has a payback period of about 5 years. From the perspective of Tehran households, this system has a return on investment of less than 4 years.
