Energy Efficiency Evaluation

At present, there is a lack of regional comprehensive energy multi-dimensional evaluation system and calculation of different quality energy in the energy efficiency evaluation of regional integrated energy system. Based on this, this article carries out research on multi-dimensional energy efficiency evaluation index system and evaluation methods. First, this article form quantifiable evaluation indicators from the aspects of energy supply subsystem energy efficiency, energy conversion subsystem energy efficiency, grid energy efficiency, economic benefits and social benefits, and clarify the calculation methods of each evaluation indicator. Then this article calculate the indicator combination weight. Finally, a multi-dimensional energy efficiency assessment method for a regional integrated energy system is proposed, and an example is used to prove the effectiveness of the method.

Coke Industry

At present, the excess capacity in China’s coke industry can be deployed to utilize some low-rank coal, replacing coking coal with potential economic gains, energy efficiency, and environmental benefits. This study presents a life cycle analysis to model these potential benefits by comparing a metallurgical coke technical pathway with technical pathways of gasification coke integrated with different chemical productions. The results show that producing gasification coke is a feasible technical pathway for the transformation and development of the coke industry. However, its economic feasibility depends on the price of cokes and coals. The gasification coke production has higher energy consumption and CO2 emissions because of its lower coke yield. Generally speaking, using gasification coke to produce F-T oils has higher economic benefits than producing methanol, but has lower energy efficiency and higher carbon emissions.

Effectiveness And Efficiency

The main objective of this paper is to present the advantages of using Cost-Benefit analysis in energy efficiency projects implemented in public buildings, and to prove the hypothesis that Cost-Benefit analysis boosts the effectiveness and efficiency of the said type of projects. The paper offers theoretical and practical explanation of the implementation of Cost-Benefit analysis in the relevant area. Since energy efficiency projects in public buildings usually represent a part of a broader portfolio of similar projects and their implementation demands allocation of substantial financial resources, communities are often be interested in achieving maximal economic and non-economic benefits. This paper aims to demonstrate that Cost-Benefit analysis can represent an excellent contribution when attempting to select the projects for implementation within a broader portfolio of energy efficiency projects in public buildings. This hypothesis was demonstrated by putting a greater emphasis on non-economic benefits and the costs arising from implementation of the aforementioned types of projects. In addition, a practical test of this hypothesis was performed through the implementation of an energy efficiency portfolio in public buildings, worth several tens of millions of dollars - the Serbian Energy Efficiency Project. The paper concludes that the use of Cost-Benefit analysis can help us to effectively evaluate and manage projects of this type aimed at achieving maximum benefits for the community in question.

The paper presents a proposal of economic aspects application in the process of optimizing the construction of heat recovery unit. The proposed model includes the cost of heat exchanger installation and the predicted economic benefits during the operation of the device. The predicted benefits include an increase of energy efficiency resulting from the number of modules of heat recovery unit, decrease unit efficiency during operation, the cost of heat production, average temperatures in the geographical location and working time. A case study was carried out on the example of a spray booth.

Improvement Measures

Air conditioning and refrigeration equipment are more and more widely applied, It’s energy efficiency proportion of total energy consumption is growing. To evaluate energy efficiency and apply high grade energy efficiency of air conditioning , that can bring considerable economic benefits and improve energy-saving initiative for the enterprises. This has great practical significance to realize Chinese energy-saving task. In this paper the air conditioning energy efficiency ratio(EER), seasonal energy efficiency ratio(SEER) and integrated part load value(IPLV) are proposed and analyzed, Many evalution methods are put forword to provide appropriate evaluation criteria for enterprise, and the energy-saving measures on the different assessment criteria are also put forward, It has some guiding significance to improve the efficiency of air conditioning and refrigeration equipment.

The operation strategies are key points that can influence the annual total energy efficiency, energy saving efficiency and economic benefits of BCHP systems. This paper mainly aims at establishing the model about how to realize several typical operation strategies of BCHP systems based on gas engines, such as operation following the power load and operation following the heating load. Also, in a specific project, operation strategies always depend on the load feature and the government policy and the price of power and etc. This paper includes methods about how to choose the operation strategies reasonably.

Maximum Comfort

The modern materials and technologies have an ability to provide a solution of the main goal of modern construction − maximum comfort. This article shows the implementation of comfortable building in a project of primary school. All the components of comfort have been taken under consideration: a rational space-planning, energy efficiency, acoustic isolation, air-tightness, daylight, fire safety, visual aesthetics. Special attention has been given to energy-efficiency: heat transfer coefficients have been calculated, optimal constructions have been selected, involving alternative methods of producing energy. The class of the building’s energy has also been determined. Economic benefits have also been described due to using renewable energy, area economy and so on. As a result, the concept of "comfort in all respects" have been revealed, recommendations on its implementation and further research in this area have been given.
