Abstract
The aim of the research is to analyze heat losses through the outward enclosing constructions of the buildings of the first mass series before and after the sanitation. As measures for sanitation, walls, ceilings, attic and ground floors were chosen for the insulation, as well as replacement of old wooden windows in polyvinylchloride windows with double-glazed pane, replacement of wooden entrance doors in warmed metal ones. Materials for insulation are chosen in accordance with the climatic features of Arkhangelsk. The calculations were carried out in accordance with the requirements of modern regulatory documents. Based on the obtained data, as well as the duration of the heating period and the current tariff, the amount of savings in thermal energy is determined. This information allows to conclude that the proposed activities are energy-efficient. Savings on heating after sanation: for «Stalin’s serie», will be 272 thousand rubles, for «Khrushchev’s serie» - about 410 thousand rubles and for «Brezhnev’s serie» - 930 thousand rubles in year.
Highlights
A significant part of the Arkhangelsk housing consists of the buildings of the first mass series: «Stalin’s serie», «Khrushchev’s serie» and «Brezhnev’s serie» .The most active period of their erection was the 50s - 90s of the 20th century
The subject of the research is sanitation, aimed at increasing their energy efficiency. This topic is relevant in the territory of the CIS countries. Various aspects of this topic have been considered in many articles and scientific papers: methods of sanitation of buildings of the first mass series [2,3,4], technological features of reconstruction [5,6,7,8], the creation of a project for the organization of construction during reconstruction [9], calculation of costs for facade insulation and economic justification of the reconstruction [10,11]
The procedure of heat engineering calculation of enclosing structures is described in the above-mentioned formulary SP 50.13330.2012 «Thermal protection of buildings» [1], formulary SP 23-101-2004 «Design of thermal protection of buildings» [15] and State Standard R 54851-2011 «Nonuniform building enveloping structures» [16]
Summary
A significant part of the Arkhangelsk housing consists of the buildings of the first mass series: «Stalin’s serie», «Khrushchev’s serie» and «Brezhnev’s serie» .The most active period of their erection was the 50s - 90s of the 20th century. The main purpose of the construction was to solve the problem of housing shortage, which was achieved. Most of these buildings do not meet modern demands, in particular, the requirements of SP 50.13330.2012 «Thermal protection of buildings» [1]. The subject of the research is sanitation, aimed at increasing their energy efficiency. This topic is relevant in the territory of the CIS countries. Various aspects of this topic have been considered in many articles and scientific papers: methods of sanitation of buildings of the first mass series [2,3,4], technological features of reconstruction [5,6,7,8], the creation of a project for the organization of construction during reconstruction [9], calculation of costs for facade insulation and economic justification of the reconstruction [10,11]
