The work is devoted to the development of 3D models of the territory with buildings and other objects placed on it for subsequent analysis of insolation. The work describes the requirements for solar insulation of buildings, analyzed the regulatory requirements for solar insulation of premises, a schedule of monthly sundials is presented using the example of the city of Volgograd, a substrate is formed with applied contours of buildings and objects for a more convenient implementation 3D which was formed in third-party software, presents a brief analysis of the Energy software product 3D which describes the positive and negative aspects of the software, on the example of the design project of the scientific and educational center, an analysis of the insolation of the territory according to the formed 3D model was carried out. Based on the results of the analysis, the placement of objects was corrected to achieve the required illumination.
