INSOLATION: CONCEPT, LEGISLATIVE REGULATION, ROLE OF ARCHITECTURE

The study evaluates the impact of direct sunlight (insolation) for humans: physiological, psychological, biological, ecological, aesthetic, economic, etc. The research is carried out. Regulatory legal acts regulating daylighting in premises and territories in the USSR and in the modern Russian Federation are analysed. The problem of systematic violation of legal norms guaranteeing insolation is raised, as well as the tendency that leads to the reduction of daylight access to premises. The material analyses the main international documents in the field of insolation. The scientific work was prepared considering the use of such methods as analysis, synthesis, analogy, survey, testing, and others. The results of the survey questionnaire for architects about the quality of insolation of buildings are presented. The results of the study showed the main problems associated with changes in insolation regulations: poor awareness of citizens about the importance of sunlight for the human body; insufficient number of hours for the study of insolation in architectural educational institutions; unawareness of experts about the ongoing changes in the field of legal regulation of insolation. © 2025, LLC Editorial of Journal ""Light Technik"".
