FEATURES AND COMPREHENSIVE STUDY OF SACRED BUILDINGS OF THE END OF 20 – EARLY 21 CENTURY (ON THE EXAMPLE OF THE CHURCH OF ST. PETER IN TERNOPIL)

The article examines some problems of temples of the late 20th - early 21st centuries, in which modern architectural ideas, modern design components appeared together with new design solutions. The study uses a set of general scientific (empirical and theoretical) and special research methods (method of visual and instrumental surveys, historical and comparative analysis, art analysis, method of thermal monitoring and calculation). A comprehensive study was conducted on the example of St. Peter's Church in Ternopil (architect Serhiy Hora, designer Józef Simels). It is established that its modern stylistic image, modern formative components are combined with the traditional plan, which has historically developed in church construction. The facilitation of the main load-bearing structures was made possible by the use of exceptional metal curved trusses and a reinforced concrete belt. A comprehensive analysis of the condition of the church building revealed a number of problems typical for churches of this period of construction: the progressive spread of efflorescence, mycological damage to the plaster, premature destruction of building materials and destruction of structures; loss of insulative properties of structures and increase in energy consumption, deterioration of acoustic characteristics in the church space, loss of uniformity of sound distribution over its area. The dependence of these problems on changes in temperature and humidity in the temple building has been established. According to the results of instrumental research, a correlation analysis was performed to assess the degree of relationship between the distribution of moisture and temperature with the peculiarities of operation, the nature of operation and the level of thermal insulation of enclosing structures. The consequences of further moistening of the inner surfaces of the fences have been established: consequences for the interior; microclimatic (hygienic) consequence; constructive consequences; effects on energy consumption and acoustic effects. As a result of the calculations, recommendations for troubleshooting were provided. Using in this context a systematic interpretation of case studies, the study of actions that would help increase the level of comfort in churches and their preservation, the authors propose a reconstruction with an assessment of the quality of intervention at each stage.
