Assessment of the Insolation Duration for the Facades of Buildings and Adjacent Territories under Certain Parameters of their Development

The article is devoted to a wide scale desk and field scientific studies, devoted to a problem of solar insolation of residential buildings and near-by territories. The investigations were conducted on basis of a number of cities in Russian Federation, situated in different insolation zones of country. The different type of residential blocks, as regards to their size, shape, height, etc., was chosen for the studies in question. The lasting of solar insolation period in cardinal standard months of year in relations to the above mentioned factors was determined and this gave a possibility to make a number of general conclusions and to represent some recommendation for architectural and structural design of residential buildings and urban development in general. The article also proves the importance and validity of the latter changes, which were put into the contemporary “Sanitary Codes and Regulations” of Russian Federation in the section on insolation of buildings and territories.
