The Impact

Energy efficiency improvement in industrial companies is an essential prerequisite for the enhancement of their competitive positions in the national and global markets. Yet, the approaches currently employed in respect of the energy management do not fully utilize the innovative potential of energy technologies to achieve strategic goals. One way to further develop energy management is theoretical justification of the use of new approaches based on the suggested concept of the energy saving and energy efficiency processes’ positioning in the system of a company’s management priorities. In this article, we consider the applied use of the developed conceptual approach from the perspective of the energy saving and energy efficiency program development at the company. The main purpose of this paper is to justify the relations between energy management and strategic decision making in industrial companies. The results of the research conducted, firstly, make a certain contribution into the research of strategic multiple benefits of energy efficiency in a company; secondly, they expand understanding of the impact of energy saving and energy efficiency improvement on the achievement of operational, tactical and strategic results of the company’s activities; thirdly, they provide methodological decision support for the development of energy saving and energy efficiency programs taking into account the management and organizational barriers.

The Republic

This article deals with the problem of energy saving and energy efficiency improvement in the construction sector, which consumes a significant share of the country's energy resources. Issues of rational use of energy resources with aspects of energy saving, energy efficiency and, accordingly, environmental problems are becoming more and more urgent, and their solution has become a strategic task for Kazakhstan. With the aim of catalyzing the energy-saving measures undertaken in Kazakhstan, a number of laws, subsidiary laws and programs related to the issues of rational use of energy resources and energy efficiency improvement have been adopted. Targeted activities are planned to eliminate existing political, legislative, technical and information thresholds in order to solve this problem. The regulatory and technical framework premised on the advanced achievements of construction science is being developed. The current legal and regulatory framework and technological infrastructure, as well as the existing practice, are being analyzed. In this context, actions are being taken to introduce new mandatory requirements for thermal indexes in building regulations and other changes in the energy efficiency of buildings; systems for assessing and labelling energy efficiency and their implementation are being developed. Voluntary standards for "green buildings" and incentive mechanisms for their application are also being developed, procedures for State architectural and construction supervision of compliance with building standards and other requirements for the construction of buildings are being improved, greenhouse gas accounting systems are being developed and implemented based on data from the energy consumption accounting system and energy passports.

Hermetic Compressor

This research presents an energy efficiency improvement solution for supermarkets with the use of low-E glass doors for open refrigerators and a digital semi-hermetic compressor to fix the speed of semi-hermetic compressors. The impact of a door’s installation causes its load to be reduced by 40%, and the compressor shuts down frequently, which decreases its lifetime. In order to ensure that energy-saving solutions do not affect maintenance costs, the installation of a digital semi-hermetic compressor is proposed to lower costs and save energy. Our economic results from tests carried out at a 3000 square meter supermarket, which was open from 6:00 am to 12:00 am and in which we installed 82 doors on 15 open refrigerators, showed a 1.1-year payback period with an energy saving rate of 192,220 kWh/year for store No.1 (R22) and in which we installed 80 doors on 15 open refrigerators, showed a 1.4-year payback period with an energy saving rate of 171,185 kWh/year for store No.2 (R404A). The energy-saving effects of the digital semi-hermetic compressor, which fixes the speed of the semi-compressor and solves the problem of impact from fridge door installation, showed a 2.9-year payback period with an energy saving rate of 26,890 kWh/year for store No.1 (R22) and showed a 2.9-year payback period with an energy saving rate of 26,571 kWh/year for store No.2 (R404A). The results of store No.1 (R22) and store No.2 (R404A) showed no differences. This research is an extension of an energy-saving project that can be carried out on a continuous basis, increasing the efficiency of energy use and being a sustainable source of energy conservation.

Energy Efficiency Improvement

Electricity industry is one of the most important industries that contributes to Thailand’s economic growth. Power generation requires a huge amount of energy and emits a great number of greenhouse gas emission. Reducing energy consumption by improving its efficiency will be beneficial in both economic and environmental aspect. In this study, ten measures related to power generation and distribution system were assessed and analyzed its emission reduction via clean development mechanism and evaluated its cost effectiveness by using the net present value method. The findings revealed that changing a burner with better efficiency was the best implemented measure providing a great point not only on total energy saving but also on gross emission reduction and on earning back the investment. The results in term of intensity of energy saving and emission reduction, however, demonstrated that replacing an old transformer with a new high efficiency one was the most effective measure because using it for a long time period results in high value of no load loss. The information regarding the potential of greenhouse gas emission reduction on the energy efficiency improvement of each measure would be a useful information for decision makers or other parties in power sector to understanding and planning the suitable strategies in the future.

Preparatory Work

The challenges of increasing the energy efficiency of the economy as a whole and of certain production sectors in particular are a priority both in our country and abroad. As part of the energy policy of the Russian Federation to reduce the specific energy intensity of enterprises in the oil transportation system, Transneft PJSC developed and implements the energy saving and energy efficiency improvement Program. The application of energy-saving technologies allowed the company to significantly reduce operating costs and emissions of harmful substances. At the same time, further reduction of energy costs is complicated for objective reasons. The objective of this article is to present additional methods to improve the energy efficiency of oil transportation by the example of the organizational structure of Transneft. Possibilities to reduce energy costs in the organization of the operating services, planning and execution of work to eliminate defects and preparatory work for the scheduled shutdown of the pipeline, the use of pumping equipment, including pumps with variable speed drive, the use of various pipelines layouts, changing the volume of oil entering the pipeline system and increase its viscosity.
