Subject: the methods of optimization of organizational-technological and design solutions for installation of energy-efficient enclosing structures are described in the article. The results of research on the development of hinged ventilated facade systems with the use of factory technology are given. A comprehensive analysis of domestic and foreign facade systems, together with the technology for production of works on their installation, has been carried out; their operating properties have been studied. The main design and technological solutions for manufacturing and installation of facade panels on the construction site, the features of the mechanization tools used, control of work quality and reliability of the system are presented. The system for manufacturing ventilated facades with high manufacturing readiness level and a wide range of applications is developed on the basis of theoretical and design solutions. The use of this technology in monolithic and large-panel housing construction significantly reduces labor intensity and cost of work. The core of the research was the use of methods for reducing labor costs during installation of energy-efficient ventilated facades and improving the quality control of installation work by developing new design and technological solutions. Goals: the aim of the research is to develop an industrial technology for installation of energy-efficient enclosing structures by optimizing production processes during manufacturing and installation of facade systems by the method of aggregate assembly. Materials and methods: the basis of the proposed method is the technology for manufacturing reinforced concrete enclosing elements of a width equal to the axial dimension between the inner bearing walls. Several types of panels with window and door apertures (for loggias and balconies), and also bay windows, have been developed. Results: the comprehensive studies have shown that the use of factory-made ventilated facade panels allows us to reduce the labor intensity of work by 4-6 times with the provision of high quality facade works. Technologies for production of works on installation of enclosing structures, arrangement of a construction site and workplaces that meet the requirements of Federal Laws No. 384-FZ and No. 123-FZ have been developed. The design solution of the developed façade system takes into account the requirements of GOST 11024-2012 and GOST 13015-2012, and also the requirements of certified albums of technical solutions for arrangement of elements of the subsystem and insulation. In accordance with the current building codes and data, obtained experimentally and analytically, and also by regression analysis, trend lines for the dependence of specific labor costs and work production costs have been obtained. Conclusions: the developed design and technological solution for mounting hinged ventilated facades is relevant both to monolithic and large-panel housing construction. Further development and identification of the most rational organizational and technological solutions for installation of energy-efficient enclosing structures will be able to affect the reduction in duration of residential building construction.
