Testing Work

With the deepening of the energy conservation of the building, energy saving from the original design of building energy-saving gradually turned to the field detection and completion acceptance, which requires a corresponding energy-efficient means of detection. With the development of infrared technology, the combination of infrared technology and detection methods of building energy-saving, to further promote the development of building energy efficiency testing work. Compared to the traditional heat flow meter or hot-box method, infrared thermal imaging method has no effect on the measured object, detecting the surface temperature of quick reaction speed, accompanying with wide temperature range and high precision, is widely used in various fields of testing work, which has been particularly prominent in the thermal defect detection. In this paper, the method of infrared thermography is used to confirm whether the thermal defects exist in energy-saving construction or not. Testing results show that infrared thermography can accurately reflect the temperature distribution of building wall surface. Infrared thermal imaging to detect the building surface's energy efficiency, which is providing efficient and accurate means of detection for the evaluation of the building energy efficiency. This is to help carry out a comprehensive building energy-saving testing.

The relevance of the research topic is that energy-saving is the key element of modern energy development in the country. In Kazakhstan, energy-saving, and improving the energy efficiency of agriculture is currently a priority task that will solve energy, environmental and economic problems. Without a solution to these problems, the country's development will inevitably hold back. The head of state in the field of energy conservation has set a goal to reduce the energy intensity of the gross domestic product by at least 25% by 2020, and annual energy-savings of 3.5% after 2020. Industry in rural areas consumes more than 70 % of all electricity. As part of the comprehensive plan, their energy audit was conducted 50/50 (50 % of the financing is the enterprises' funds, the remaining 50 % is the state budget). As a result of the energy audit, systematic measures were developed to reduce the energy intensity of the industry, including the electric power industry. Large unproductive losses of energy resources are in the private sector, in this connection, since 2019, the energy audit of JSC "Kazakhstan center for modernization and development of housing and communal services (housing and communal services)" is conducted on budget funds in the private sector. Energy conservation is one of the most important and strategic tasks of the country. Rapidly developing production requires additional energy costs. This is confirmed by the annual increase in energy tariffs. In turn, resources are not unlimited, and their irrational consumption will inevitably lead to not only economic but also to an environmental crisis.

The report analyzes the role and importance of energy conservation for Georgia. Based on concrete materials, the effectiveness of social labor and energy savings on gross domestic product (GDP) is comparable to each other. It is said that the reduction of GDP energy efficiency by 1% is almost the same, and in more than a few years, the result of GDP increase is more than the same as the productivity of public labor. In this regard, the report describes the level and dynamics of major macroeconomic indicators of the economic development of Georgia for 2013-2016. Set up events to improve the situation.

The Cost

The current problem of ensuring energy saving and improving the energy efficiency of buildings and structures for agricultural purposes is identified. The geopolitical situation, import substitution programs and agricultural development programs set the task of developing domestic vegetable production, which in its turn requires the construction of new vegetable store buildings, as in most regions of Russia the harvest is collected once a year. In this regard, the current task is to ensure the energy conservation and achieve high energy efficiency of the vegetable store buildings. Energy saving is the basic technology for creating effective agriculture. The purpose of the study is to analyse the requirements for insulation materials for buildings and vegetable store facilities, taking into account energy efficiency and life cycle cost. The authors analysed the criteria for choosing a heater for the vegetable stores: low coefficient of thermal conductivity, water absorption, sorption humidity, frost resistance, biostability, lack of cold bridges, long service life. It is proposed to supplement the criteria for choosing a building insulation with the characteristics of the life cycle cost and the service life. Design and construction of agricultural buildings is proposed to be implemented using the concepts of BLC and BIM, the use of which gives an opportunity to design buildings with optimal energy efficiency parameters and take into account the cost of the life cycle. The cost of the buildings life cycle is the main of all the performance indicators when comparing alternative design options that differ by the application of advanced technologies and material resources and the contractors' offers when concluding contracts not only for purchase, but for servicing the subject of trades during its service life. The conclusions are made about the advantages of using foamed polyethylene foam for warming vegetable store buildings, as well as the conclusion about the expediency of adding criteria determining the sustainable development of the human environment, namely life cycle cost, service life, recycling ability. The formula for calculating the cost of the buildings life cycle, adapted to the specificity of buildings for agricultural purposes, is given.

Energy conservation is attracting more attention to achieve a reduced lifecycle system cost level while enabling environmentally friendly characteristics. Conventional research mainly concentrates on energy-saving speed profiles, where the energy level evaluation of the timetable is usually considered separately. This paper integrates the train driving control optimization and the timetable characteristics by analyzing the achievable tractive energy conservation performance and the corresponding boundaries. A calculation method for energy efficient driving control solution is proposed based on the Bacterial Foraging Optimization (BFO) strategy, which is utilized to carry out batch processing with timetable. A boundary identification solution is proposed to detect the range of energy conservation capability by considering the relationships with average interstation speed and the passenger volume condition. A case study is presented using practical data of Beijing Metro Batong Line and two timetable schemes. The results illustrate that the proposed optimized energy efficient driving control approach is capable of saving tractive energy in comparison with the conventional traction calculation-based train operation solution. With the proposed boundary identification method, the capability space of the energy conservation profiles with respect to the energy reduction and energy saving rate is revealed. Moreover, analyses and discussions on effects from different passenger load conditions are given to both the weekday and weekend timetables. Results of this paper may assist the decision making of rail operators and engineers by enhancing the cost effectiveness and energy efficiency.
