METHODOLOGICAL ASPECTS OF ENGINEERING AND TECHNOLOGICAL ISSUES OF FACADE SYSTEM DESIGN TAKING INTO ACCOUNT THE REQUIREMENTS OF CURRENT BUILDING ENERGY EFFICIENCY TRENDS

Abstract

Purpose. The study of existing approaches to the assessment of the energy efficiency of external enclosing structures and the technical and economic justification of the choice of structural solutions of facade systems for equipping the external enclosing structures of the «Yunist» substation in the city of Zaporizhzhia on the basis of variable design, which allows to reduce heat costs for heating and the energy consumption of building operation. Methodology. An important role in the research is played by the formation of knowledge and skills in the use of a modern design and technological approach to solving the problems of choosing a facade system in the design of buildings to obtain maximum energy efficiency and separation of the style of the building in the conditions of urban development. Findings. The work examines the methods of determining the indicators of operational efficiency of facades of buildings and structures, as well as studies additional information from foreign and domestic sources, analyzes typical projects that have already been implemented on the territory of the city of Zaporizhzhia. In the course of the work, effective organizational and technological solutions for facade works were developed on the basis of experimental and statistical modeling. Originality. A comprehensive review of aggregated costs for the execution of external finishing works, structural features of the facade system with the nature of the action of atmospheric factors, taking into account the architectural solutions of the real construction site in the city of Zaporizhzhia. The analysis of the research results showed that high efficiency of facade works at low costs can be achieved only when choosing and designing engineering solutions that combine the design of the facade system and the environmental characteristics of the building object. Practical value. Recommendations regarding taking into account the climatic and ecological characteristics of the city of Zaporizhzhia, where the «Yunist» station is located, their impact on the operational efficiency of the decorative elements of the facade.
