An important task of the architect is to create a high-quality living environment that allows residents to fully develop physiologically, get a sense of comfort and aesthetic pleasure.
An important regulatory and restrictive factor that significantly affects the indoor climate, the planning structure of apartments and the number of stores of residential buildings is the need to ensure the optimal duration of insolation in apartments and the surrounding area.
The purpose of the article is to draw attention to the quite frequent non-compliance or ignoring by architects of the requirements and norms of insolation when designing multi-stores buildings and their complexes in the historical area of the city.
It has been established that in a number of residential complexes built in Lviv over the past decades, many apartment rooms do not meet the insolation rate or experience thermal discomfort in the summer. Using a specific example of a group of residential buildings, the factors that affect the insolation regime in the premises are identified. First of all, it is the shape of individual buildings, the way they are mutually located, the planning characteristics of apartments, and the parameters of structural elements on the facades that shade the windows. It has been established that the reason for the reduction in the duration of insolation is also their incorrect orientation along the sides of the horizon, as well as the influence of existing buildings.
Using specific examples of existing residential complexes, it was found that the problem lies not only in the lack of optimal insolation duration in the buildings themselves, but also in insufficient insolation of the territory adjacent to the buildings, inefficient use of public space.
The results of the study can be used as a recommendation material for the design of multistory residential buildings in existing urban development.
