A complete understanding of the limits, barriers, and equipment available for the use of national energy resources is essential. This will increase the use of existing regional energy potential and pave the way for sustainable development. In this study, the Green Cottage power management system from a renewable energy source was designed and evaluated using a decision-making algorithm. Thirteen scenarios were extracted to Zero-energy building. The results show: If the penetration of renewable energy is 24% with an average daily fossil fuel consumption of 1.11 liters per year, the energy produced by the Hybrid renewable energy systems (HRES) is equal to 1697 kWh / yr and the net present value (NPV) is $ 5553.68 and the Internal rate of return (IRR) equals 21.49% with a payback period (PP) of 15.71 years. With the increase of renewable energy penetration to 54%, fossil fuel consumption became 0.694 liters and the annual production energy was equal to 1652 kWh / yr and the NPV was 19.5% with a PP of 17.61 years. Zero-energy building Energy Management with 100% renewable energy penetration, 1933 kWh / yr per year without emissions of environmental pollutants, and the NPV equal to -372.09 dollars. From the point of view of energy policy, if the feed-in tariff of renewable energy increases to more than $ 0.06, the implementation of this scenario will be economic.

Keywords: Energy Potential, Decision-Making Algorithm, Renewable Energy, Zero-Energy Building, Hybrid Renewable Energy System (HRES).
