Recommendations For Restoration Of Historical Transparent Coatings In Pushkin Museum

Abstract

Due to the intensification of historical buildings restoration works that are cultural monuments and related to architectural monuments, numerous questions arise about the possibility of increasing the efficiency of translucent structures, including their energy efficiency, using modern innovative technologies. The cost of competent reconstruction of windows and lanterns with the preservation of historical elements is much higher than the cost of standard modern structures, as a result of which there are numerous examples of barbaric illegal replacement of historical windows with modern ones. This not only spoils the appearance of buildings, but also contradicts federal laws (with all the ensuing consequences). Earlier, NIISF RAASN carried out multifactorial field studies of historical translucent coverings of a cultural monument of federal significance – the main building of the Pushkin Museum, on the basis of which their inconsistency with modern requirements for such structures was established. According to the technical assignment and the project for the reconstruction of the building, 13 options were proposed for the possible restoration of these coatings. To assess the proposed options, a comprehensive computer simulation and corresponding calculations were carried out in accordance with the certified software package “WINDOW TECT”. On the basis of the conducted examinations and computer calculations, optimal solutions were proposed for the restoration of historical translucent coatings of the main building of the Pushkin Museum, providing for the preservation of the original elements of metal structures and ensuring an increase in the thermal characteristics of the lantern and side lamp.
