Abstract. The paper is devoted to the development of approaches to optimum selection of space-planning and structural solutions of low-rise buildings for different kinds of territories. The aim of the study is to develop a system of criteria that influence the choice of optimum space-planning and structural solutions of buildings and structures aimed at enhancement of capital investment efficiency, energy and resource efficiency and creating comfortable living conditions for people. Developed solutions can be applied during implementation of investment construction projects of low-rise housing at different kinds of territories based on the local building materials.

Article is devoted to the formation of a regional model of development and management of processes to improve energy efficiency of low-rise residential construction in Russia. Authors define the role and place of low-rise construction in the national socio-economic priorities, as well as the method of forming regional models. Developed a set of indicators to measure the effectiveness of the implementation of the model. The analysis and evaluation revealed the ineffectiveness of the existing state of regional development programs for low-rise construction. The main objective of the study is to develop a theoretical basis and practical recommendations for the formation of affordable low-rise housing that meets the requirements of energy efficiency and environmental friendliness. Authors have solved the problem of forming a model based on a systematic and interdisciplinary approaches, and demonstrate the effects associated with its implementation. The study uses the methods and principles of object-logical

Objective: The objective of this research is to develop an integral approach for the efficient choice of space-planning and structural solutions for low-rise buildings using renewable energy sources for engineering systems during the full life cycle of the building, aimed at improving efficiency of capital investments, energy and resource conservation, and creating comfortable living conditions for the population while considering climatic zoning. Method: The research used a theoretical and methodological approach to develop the foundations for the efficient choice of space-planning and structural solutions for low-rise buildings. The study utilized a comparative analysis of building materials and heat supply technologies to select the most appropriate options. Results: The research showed that utilizing renewable energy sources for engineering systems during the full life cycle of a low-rise building can significantly reduce construction expenses while increasing availability of low-rise housing for certain categories of citizens. The developed integral approach allows for the most efficient choice of space-planning and structural solutions for low-rise buildings while taking into account climatic zoning. Conclusions: The research provides a means of solving the problem of supplying citizens with low-rise housing with high level of comfort and quality. The results of the research can be used in implementation of regional strategic sectoral planning and public-private partnership projects’ development. The developed integral approach allows for the rational utilization of autonomous heat supply sources in low-rise residential construction projects.
