As energy is the main ‘fuel’ for social and economic development, and since energy-related activities have significant environmental impacts, it is important to lower emissions and stabilize atmospheric CO2 levels to avoid the worst predicted effects of climate change. Reducing energy consumption and costs is becoming central to planning, construction, and use of energy construction facilities from an environmental and economic point of view. Each energy source has advantages and disadvantages referred to: operating costs, environmental impact, and other factors. Each generation method produces some greenhouse gases (GHG) in varying quantities through construction, operation, and decommissioning. Some generation methods like coal fired plants release the majority of GHGs during operation. Others, such as wind power and hydro power release the majority of emissions during construction and decommissioning. Normalizing the lifecycle emissions with electrical generation allows a fair comparison of different generation methods on a per gigawatt-hour basis.

The work is devoted to assessing the environmental and economic efficiency of construction waste recycling concerning the sustainable development of civil real estate. The crisis processes in the micro-and macro-level economy has a negative impact on the Russian investment and construction complex, which threatens the national task performance to provide affordable housing within implementation of the investment programs financed by municipal and federal budgets. It is shown that one of the directions of sustainable reproduction of real estate objects in modern socio-economic conditions is the optimal design and selection of materials using innovative recycling technologies. Low rates of retiring areas replacement and a steady trend of growth in the volume of construction industry waste is observed. This approach is focused on solving two global problems: the economic benefits of using resources and the elimination of environmental pollution. Proposed algorithms evaluate the potential effectiveness of the property manager’s activities and the practical implementation of the techniques in management software.

The article is devoted to the issues of ontology, research of the effectiveness and prospects of large-panel and monolithic reinforced concrete construction of residential objects. Increasing demands on the effectiveness of multi-story housing construction determine the relevance of this study. Methodological foundations of substantiation and a comparative analysis of the effectiveness of monolithic and large-panel reinforced concrete multi-story construction are considered; prospects for the development of these housing technologies are justified. The article presents an analysis of the pros and cons of monolithic and large-panel reinforced concrete multi-storey construction of residential buildings, a comparative analysis of the processes of organization and technology of construction works. The problems of large-panel and monolithic construction are ranked according to the level of their materiality, measures to improve construction technologies are proposed. The comparative analysis of cost indicators of monolithic and panel construction on the basis of the data presented in collections of standards of the price of construction is presented. The need to introduce and update the normative documentation having legal force for regulation of the basic provisions of the modern improved large-panel construction is proved. Attention is paid to the design conditions for the manufacture and installation of the monolithic and large-panel multi-storey construction of residential buildings used in the methodological approach. Cases of expediency of comparison on criterion "duration of construction" are analyzed. The article proposes an original methodological approach for evaluating the effectiveness of monolithic and large-panel construction, taking into account the conditions and nature of the uncertainty of the initial data, which will justify the choice of the most effective options for the construction of multi-storey housing construction.
