Abstract

In architectural practice, a stable understanding has developed about the positive aspect of insolation of premises and territories, which consists in the sanitization of premises with the UV part of the spectrum, erythema effect on humans, thermal effect on buildings, and regulation of building density. An analysis of the current insolation standards is given to take into account each of the above factors. It is shown that most of them are not only not taken into account, but the very ideology of the positive impact of insolation of premises and territories is lost. The identified problems and contradictions suggest the need to revise the current insolation standards. A method for determining calendar dates for excluding insolation based on the duration of overheating of a room in the summer is proposed. Examples of architectural solutions are given in which the current insolation standards and calculation methods conflict with each other. Justifications are proposed for revising the standards for insolation of premises and territories while maintaining the required building density.
