Some Aspects of Energy-Efficient Technologies Application in Historical Buildings’ Renovation

Abstract

Energy saving is one of the important directions of modern strategy in the field of construction because in Ukraine, twice as much natural fuel is consumed per 1 million m3 of living space during the heating period as in Europe. Energy-efficient reconstruction of buildings consists of ensuring energy-saving functioning through the use of modern active engineering and technical solutions and technical installations, as well as possible passive measures (wall insulation, optimal type of double-glazed windows, etc.). The issue of energy efficiency during the renovation of historical buildings requires special attention because the building is a collection of architectural and urban heritage objects that are subject to maximum preservation. The purpose of the article is to reveal the peculiarities of the renovation of historical buildings using modern energy-saving technologies based on the analysis of world experience. A common problem with many historic buildings is their careless maintenance, which leads to a number of technical deficiencies, such as high energy consumption and low thermal comfort. Therefore, the need for renovation of historical buildings is met by combining restoration work with measures to ensure energy efficiency. The article highlights the issue of increasing the energy efficiency of buildings related to historical architecture using the examples of the Sofiero Castle located in Helsingborg (Sweden), the Palace of the Hungarian Academy of Sciences, the Aspinall Courthouse (USA), and the Osram building (Denmark). First and foremost, theoretical developments on this topic are considered. The main modern methods of increasing the energy efficiency of buildings are outlined. Examples of world experience in the use of energy-efficient technologies and energy modernization during the reconstruction of buildings related to historical architecture are given. The design and implementation of works on the restoration of historical monuments, as well as the application of appropriate energy efficiency measures, require an individual approach to each historical building after careful analysis of the world's modern one’s theoretical developments and practical experience.
