Abstarct: Given the direct impact of the excessive consumption of fossil fuels in global warming, one of the effective solutions to problems has been the particular attention to high consumption of buildings. On a large scale, buildings are one of the best opportunities to reduce energy consumption and limit energy consumption. Comparing the energy intensity of the domestic part of Iran with several other countries represents a much higher share than the global average of energy in this sector. In the country, between 37% and 45% of the total energy produced is consumed in this sector, while energy consumption in this sector is not considered as a non-productive part of the country's value-added, therefore, the design and construction of energy-efficient buildings in The design and pre-building process, as well as the assessment of energy performance and the provision of solutions to reduce the energy consumption of existing buildings in the country, should be a priority in the construction sector. Zero energy buildings are the highest level of this approach. The goal of this dissertation is to create a practical design guide to help architects design a netzero-energy building. The main emphasis of this study is on reducing the energy demand of buildings by implementing the basic principles of building physics in the design process and the role of architectural design solutions (low-cost solutions) in order to achieve a netzero energy building during a case study project in Shahrood. For this purpose, the most accurate software available in the field of energy efficiency simulations with high precision, including the DesignBuilder as the main software and the Honeybee,Ladybug and Galapagos plugins for Grasshopper, and also the Insight360 plugin for Revit as auxiliary software Meteorological data analysis software such as the climate consultant has been used. Uncertainties in simulation due to the use of unrealistic data in the design of this building on the basis of other countries' standards can result in a largely unrealistic result with a high error rate. Our initiative to obtain accurate data baxsed on actual conditions in the design of netzero energy housing, assessment of the energy performance of a common residential building, and the harvesting of all the data required from this building, by field surveying and the use of thermography and databaxses with temperature data Width and humidity of the environment are the baxse conditions. In the next step, using the Energy Saving Plans, we upgraded this building baxsed on ISIRI14253 from E to B standard. Subsequently, the design of zero net energy housing design is done using accurate meteorological data analysis using passive solutions, energy efficiency solutions and renewable energy systems. Simulation results show that energy consumption of conventional residential building in Shahrood is 302.875 Kwh/m2. Finally, using the principled design baxsed on the above-mentioned solutions in the netzero-energy building design process, we managed to bring the energy consumption of the building to 19.89898 kWh / m2, which brings about 93.429% of energy savings. We have also created a high level of thermal comfort for the residents of the building. At the last stage, using photovoltaic panels, we were able to compensate for this energy demand throughout the year and reach the residential building with a net zero energy balance.
