    Abstract. The radiation ambient temperature is one of the microclimatic indicators of urban areas, which determines the safe stay of people in them during the warm period of the year. The ability of artificial coatings to accumulate and radiate heat energy should be taken into account in making competent urban planning decisions to eliminate or reduce the additional heat load on the urban environment. The calculation of radiation temperatures of the environment contributes to the adoption of environmentally safe urban planning decisions of specific areas. Using such "tools" as changing the orientation of the urban object to the cardinal directions, thermal properties of anthropogenic coatings, their concentration (density), and exposure, it is possible to control the radiation power of the surrounding surfaces, and, accordingly, the value of radiation temperatures. Research with the use of the globe thermometer confirms change in the radiation temperatures. In this case, the elementary area can be replaced with the reduced site, which will be the limit when calculating the irradiance coefficients of the required accuracy from the elements of urban development. The size of the reduced site is usually a uniform architectural element of the facade plane, for example, the size of a standard window or half of the average wall panel, etc., which is convenient for assigning the materials of the above sites radiation absorption coefficients and calculating or measuring the surface temperature. A method for calculating radiation temperatures, which is based on determining the irradiation coefficients from the globe thermometer to the surrounding fences of an imaginary space (parallelepiped) of the yard, with due regard for their surface temperatures, is proposed.
    Key words: ecological safety of urban environment, urban planning solution, microclimate of urban areas, irradiance coefficient, globe thermometer, radiation temperature of environment.
