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 key problems of organizing a rational investment in technical improvements (repair and reconstruction) of buildings and structures, as a way to improve the real estate functional efficiency are the quantitative ranking problems of objects to be improved according to the actual resource needs of work, the resulting economic assessment and reconstruction social effect, technical feasibility integrated assessment and work conditions. Particularly up to date is the question of quantifying the conditions for making improvements when implementing investment programs financed by budgetary funds, under which, as a rule, complex territorial improvement is carried out, or targeted programs are being implemented to improve the municipal real estate for functional purposes. To contribute to the effective solution of these problems and to be an effective tool for the established practice of managing urban real estate background, the methodological approaches presented in the work and the algorithms for constructing a quantitative assessment of the technological suitability of real estate for functional improvement are presented. The paper demonstrated the proposed methodologies practical use examples, evaluating the potential effectiveness of the property manager’s activities, proposed tools for the practical implementation of the techniques in industry software.
Introduction: The paper analyzes an experimental load-bearing structure of hybrid cast-in-place and precast lowrise residential buildings using wall panels with polymer tube confined concrete elements. Due to the improvement of design and process solutions, it is possible to decrease the cost, reduce the material and resource intensity of individual housing construction, ensuring structural safety and long life of such buildings. Methods: The authors propose a method of manufacturing wall panels, involving industrial production of retained formworks made of polymer tubes and oriented strand board, as well as their subsequent assembly and concreting at a construction site. Results and discussion: Results of the study were provided to the New Technologies and Materials in Construction interdepartmental team of the Belgorod Region Department of Construction and Transport. The proposed method is recommended for testing at sites of individual housing construction in the Belgorod agglomeration, including construction financed from the budget.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
