There is abundant literature regarding virtual reality as a technology of interest in the present age. However, there are few comprehensive studies on strategies that can improve the level of urban design research using this technique. To investigate the issue, this paper first reviews the concept of virtual reality. Next, the opinions of experts in the field of virtual reality technology are summed up and key elements needed to create a virtual reality experience and key operators that establish the actual interaction of users with virtual environments are discussed. The use of Virtual Reality Modeling (VRM) in the urban design process and is also elaborated on. Uses of this technique in urban projects and advantages and limitations of its use in the field are discussed. Finally, the paper attempts to provide practical solutions and strategies to improve the quality of semi experiments developed virtual environment. This can improve the results and findings of research conducted with the technique. Strategies discussed in this article have been mostly derived from practical experience and research in recent years by the author. They can help provide a more robust analysis and reduce the errors made in the virtual environment.

Today, the use of building information modeling (BIM) has become widespread in developed countries; however, in Iran, the use of BIM-based software has received less attention for some reasons. In the present study, in the first phase, library studies and data collection related to research objectives have been surveyed. Then the identification of indigenous indices of green architecture in Iran was identified and explained through the Delphi method with Kendall's W correlation coefficient in SPSS software as a table Test Statistics. Finally, a green villa building in the Lavasan area in Tehran was detected and designated as a sample to be studied. The building was simulated using Virtual Reality (VR) and Augmented Reality (AR) technologies in order to better understand its environment. Moreover, the energy consumption of the mentioned building during the previous year was studied by modeling it in Revit software. The results of the research indicate that the selected building, which has been claimed to be green, has a distance of 58 kWh / m² with the global standards of ASHRAE and LEED. Accordingly, the studied building does not have the fundamental requirements and basic principles to receive the green building certification according to these international rating systems. Thus, with regard to the green building information modeling in Iran, it could be inferred that due to the lack of an indigenous guide (in terms of energy consumption) provided by the authorities, the environmental ecosystems as global assets are at risk.
