| Title of the article | Review and Analysis of Methods of Sun Protection and Evaluation of Indoor Overheating from Solar Radiation |
| Abstract. | Problem statement. The indoor microclimate during the cold period of the year has been studied in sufficient detail, and the method of its provision is described in the relevant regulatory documents. The formation of the indoor microclimate during the warm period of the year has not been sufficiently studied and regulatory documents have not been developed to date. The reason for overheating of premises and the occurrence of thermal discomfort is solar radiation penetrating the premises through light openings. At the same time, the larger the glazing area is, the more solar energy will enter the premises and the more the air temperature will increase in it. In connection with the above, the study of the patterns of formation of the indoor microclimate in the summer months is a very urgent task. The purpose of the work is to analyze the existing scientific base in the field of sun protection and assessment of overheating of premises by solar radiation. The objectives of the study are: comparison of existing methods for calculating indoor temperatures under the influence of solar radiation, as well as sun protection methods; comparative analysis of Russian and foreign methods for determining the duration of overheating based on the criterion of thermal comfort; to determine further vectors for the development of sun protection using architectural and structural methods based on an analysis of research results published primarily over the past 3-5 years. Results. It was revealed that the current regulatory documentation does not contain a standard calculation method for determining the indoor air temperatures under the influence of solar radiation. The duration of the period of overheating of premises by solar radiation is not assessed based on the criterion of thermal comfort, but is reduced to a formal assessment of the value of the external total annual solar radiation. In this case, the calendar periods of sun protection coincide with the dates of insolation. The standard method for designing sun protection using Shading Devices is currently not applicable due to the lack of reference data on the solar factor of Shading Devices of various types. A standard method for determining the solar factor for Shading Devices of various types has not been developed. There is no method for designing enclosing structures using phase-change materials as one of the methods of sun protection. Conclusions. The article shows the need for scientific development of methods for calculating the indoor air temperature when a room is irradiated with solar radiation to determine the actual period of overheating and design shading devices. |
