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.

Abstract In March 2016, the Latvian government approved a new support program for increasing energy efficiency in residential apartment buildings. For the support of renovation of apartment buildings in the period from 2016 to 2023, 166 470 588 EUR will be available. Different persons, such as energy auditors, designers, architects, project managers and builders, will be involved in the process of planning, development and implementation of building renovation. At the development stage of the building renovation project, special attention should be devoted to the first stage – energy audit and technical project development. The problem arises due to the fact that each of these individuals, during the development of technical building documentation, does not work as a completely unified system. The implementation of construction project planning and organisational management system is one of the most important factors to guarantee that the quality of building renovation project is ensured in accordance with the laws and regulatory standards. The paper studies mutual cooperation, professionalism and the role of information feedback of personnel involved in the planning stage of building renovation, which is an essential prerequisite for the renovation process in order to achieve high quality of work and reduce the energy performance indicator. The present research includes the analysis of different technical solutions and their impact on energy efficiency. Mutual harmonisation of technical specifications is also investigated.

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.

The main objective of the monitoring analysed in the article is to evaluate and make recommendations of the actual energy and technical efficiency of the implemented measures of the modernization of multi-apartment buildings. More detailed assessment of energy efficiency measures implemented by modernized buildings, measurements of indoor microclimate and their evaluation is made. Based on the actual heat consumption collected before and after the modernization of buildings, the thermal balance of the building was constructed under the normative conditions. The basics of the methodology, conclusions and recommendations are also presented.

The studies were conducted on four 216-apartment buildings, which account for a 10 / 0.4 kV substations. Built by spline interpolation in the MathCAD environment, the charts of the electrical load of homes by standard indicators and based on information measurement. Turning the obtained graphs into two stages, the parameters of the rated capacities of the oil transformers 400 and 250 kVA were chosen by their parameters, since the rated power by the standards turned out to be much higher than the actual one. The variant with the TM-250/10 transformer, will save (energy efficiency) by reducing electricity losses during operation about 492,2 tons conditional fuel, in case of electricity loss (economic efficiency), the option is cheaper by UAH 268,2 thousands, which will result in emission reductions (environmental efficiency) of about 163,6 tons.
