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.

Oil and gas industry is one of the most capital-intensive industry in the world. Each step of oil and gas processing starting from exploration, exploitation, up to abandonment of the field, consumes large amount of capital. Optimization in each step of process is essential to reduce expenditure. In this paper, optimization of fluid flow in pipeline during oil transportation will be observed and studied in order to increase pipeline flow performance.This paper concentrates on chemical application into pipeline therefore the chemical can increase overall pipeline throughput or decrease energy requirement for oil transportation. These chemicals are called drag reducing agent, which consist of various chemicals such as surfactants, polymers, nanofluids, fibers, etc. During the application of chemical into pipeline flow system, these chemicals are already proven to decrease pump work for constant flow rate or allow pipeline to transport more oil for same amount of pump work. The first application of drag reducer in large scale oil transportation was in Trans Alaskan Pipeline System which cancel the need to build several pump stations because of the successful application. Since then, more company worldwide started to apply drag reducer to their pipeline system.Several tedious testings on laboratory should be done to examine the effect of drag reducer to crude oil that will be the subject of application. In this paper, one of the testing method is studied and experimented to select the most effective DRA from several proposed additives. For given pipeline system and crude oil type, the most optimum DRA is DRA A for pipeline section S-R and for section R-P is DRA B. Different type of oil and pipeline geometry will require different chemical drag reducer.

Self Instruction

Adaptive methods of energy efficiency control are looked upon under ambiguity conditions, based on self-instruction and human factor. The objective of dichotomous ranking of energy efficiency stochastic potential was set and solved in case when its probabilistic characteristics are known. In a reverse situation, it is suggested to use self-instruction for determination of the most suitable parameter of ranking procedure. A case of asymmetrical awareness of a decision-making person about ranking and a personnel responsible for energy efficiency was studied. Herewith, the forward-looking personnel chooses its indicators in such a way that the individual objective function which depends on ranking results , can be maximized. Such activity of the personnel may bring to under-estimation of the energy efficiency indicator as compared to the potential. As a consequence, application of self-instruction may pervert ranking parameter assessment. In order to solve this problem there were suggested self-instruction mechanisms in ranking which simulate personnel management under conditions of ambiguity. The results of these mechanisms functioning are estimates of ranking parameters, norms and ranks, determining personnel stimuli. There were found out appropriate conditions of mechanism synthesis of self-instruction in ranking, when a decision-making person identifies the most suitable parameter of the ranking procedure. These conditions are illustrated with the example of energy efficiency ranking self-instruction of the railway enterprise in the process of realization of «RZD» holding energy efficiency improvement program.

Recently, the city of Boulder, CO has recently approved mandatory energy efficiency standard, called SmartRegs Program, for rental properties. Improving residential energy efficiency is a goal of the city as they strive to meet the green house gas reduction targets of the Kyoto Protocol. However, energy efficiency is typically not implemented in rental units because of a split incentive between landlords and tenants. This paper evaluates the various retrofit measures that improve rental homes energy efficiency as well as the effectiveness of SmartRegs Program. First, various energy efficiency measures are evaluated through walk-through and detailed energy audits to assess their effectiveness in improving the energy performance of rental homes. Based on the results of the energy audits and survey of various stake holders, a set of recommendations have been defined to ensure that the SmartRegs program be successfully implemented in order to improve the overall performance and quality of rental homes. Moreover, it is found that energy efficient can increase the thermal comfort levels and decrease the energy costs for tenants, increase the value of the property for landlords, and help the city meet their green house gas reduction goals.

Energy Efficiency Improvement

Abstract Energy conservation is relevant to increasing efficiency in energy projects, by saving energy, by its’ rational use or by switching to other forms of energy. The goal is to secure energy supply on short and long term, while increasing efficiency. These are enforced by evaluating the companies’ energy status, by monitoring and adjusting energy consumption and organising a coherent energy management. The manufacturing process is described, starting from the state and properties of the raw material and ending with the glass drying technological processes involved. Raw materials are selected considering technological and economic criteria. Manufacturing is treated as a two-stage process, consisting of the logistic, preparation aspect of unloading, transporting, storing materials and the manufacturing process itself, by which the glass is sifted, shredded, deferrized and dried. The interest of analyzing the latter is justified by the fact that it has a big impact on the final energy consumption values, hence, in order to improve the general performance, the driers’ energy losses are to be reduced. Technological, energy and management solutions are stated to meet this problem. In the present paper, the emphasis is on the energy perspective of enhancing the overall efficiency. The case study stresses the effects of heat recovery over the efficiency of a glass drier. Audits are conducted, both before and after its’ implementation, to punctually observe the balance between the entering and exiting heat in the drying process. The reduction in fuel consumption and the increase in thermal performance and fuel usage performances reveal the importance of using all available exiting heat from processes. Technical faults, either in exploitation or in management, lead to additional expenses. Improving them is in congruence with the energy conservation concept and is in accordance with the Energy Efficiency Improvement Program for industrial facilities.
