Abstract
The rational energy consumption during the construction period is formed at the stage of organizational and technological design by a system of energy-correcting measures. The implementation of the complex of measures allows balancing energy consumption and ensuring a high-quality production process with all types of energy users, infrastructural elements of the construction site, and the organization of the operating mode of machines, mechanisms, and labor resources. The object of the study is a complex of developed energy-correcting measures in the organizational and technological design of construction projects. Research methods include multi-criteria analysis based on expert assessments applied to the developed set of energy-correcting measures for the main types of energy consumers in the organizational and technological modeling of the construction process. This analysis of fuel and energy resources consumption by enlarged consumer groups – machines, mechanisms, and equipment; technological processes and infrastructure of the construction site. Varying the time parameters of beginning of the construction works has a significant influence on the consumption of fuel and energy resources for certain groups of consumers. The results of scientific research are presented in the form of a variable complex of energy-correcting measures that allow to flexibly regulating energy consumption in the process of organizational and technological design of buildings.
Highlights
Different life cycle stages of the construction sites are characterized by different volumes or levels of energy consumption
The aim of this study is to develop organizational and technological mechanisms for regulating energy consumption for construction objects, in order to achieve that, the following objectives are set and solved: The development of energy-correcting measures and assessment of results; The development of evaluation criteria for energy-correcting measures; Multi-criteria analysis of energy-correcting measures; The ranking of energy-correcting measures according to the degree of their importance for different types of energy consumers
The analysis showed that this is due not to additional costs, but to a decrease in the share of the groups "Technological processes" and "Infrastructure of the construction site" from 17% and 9% to 3% and 7% in total consumption fuel and energy resources for modeling construction of monolithic housing facilities in a predetermined range of the boundary conditions
Summary
Different life cycle stages of the construction sites are characterized by different volumes or levels of energy consumption. The object of the study is a complex of developed energy-correcting measures in the organizational and technological design of construction projects. The development and implementation of a complex of energy-correcting measures ensures a reduction in energy consumption or achieve predetermined level in the construction process. The relevance of this study is due to the fact that vectors of the scientific and technical policy in the energy saving determine the development and improvement of technological and organizational methods of construction based on the principles of rational energy consumption [2,3,4,5,6,7,8,9]
