Calculated heat-and-technical indicators of brick external walls of the historical residential buildings

Abstract

The analysis of the external brick walls structures of the historical residential buildings (constructions of XIX century and the beginnings of the 20th century) in St. Petersburg is carried out. The heat-and-technical indicators (coefficient of heat conductivity of brick and coefficient of the heat transfer of external brick walls) are defined. That is established that the use of modern norms of design is possible. The obtained data allow to carry out some heat-and-technical and moist calculations during designing of heating systems as well during the development of measures for energy saving.
