Abstract:

RELEVANCE. Increasing energy efficiency is one of the necessary conditions for modernizing the Russian economy. High energy intensity and energy efficiency analysis are due to the combined influence of a number of factors, both global and private. Thus, for electric grid organizations the problem of energy efficiency is a priority. Having at their disposal electrical grid facilities, including points of reception and transmission of electrical energy, electrical equipment and power transmission lines, electrical grid organizations incur huge losses caused by losses during the transmission of e

Abstract:

The study is devoted to the process of evaluating the efficiency of the transport system in terms of urban mobility. The approach is based on the use of a system of performance indicators using neurocomputer technologies. Generalized models for obtaining a vector of performance indicators and an integral performance indicator in the form of computer neural networks are proposed. It is shown that to record the fact that the indicator values fall to the threshold and below, it is enough to use a neural network built on perceptron neurons. The multi-layered model for determining the integral indi

Abstract:

The correct determination of the energy efficiency (EE) of a complex system is a problematic task that requires the use of specialized methods and approaches. Most often, EE is considered as an indicator of the quality-of-service provision, which most fully corresponds to the technical and economic essence of this indicator. The structural and functional organization of the system of such indicators is carried out either on a bottom-up approach or a top-down approach, gradually deploying macroeconomic indicators defined at the system levels. This paper considers the tensor form of organization

Abstract:

Hotels are energy-intensive buildings; therefore, in this study, we investigate the indicators used for measuring the energy efficiency of one- to five-star hotels, in temperate and tropical regions of Asia, Europe, and Africa. There are several indicators for measuring energy intensity, but we found that the “total average annual energy use intensity index”, measured in kilowatt-hours per square meter per year (kWh/m2 year), was most often used. Surveys and energy audits are the methods used most often to collect the indicator data. Hotels in the tropics tend to consume more energy than those

Energy efficiency has long been an important issue to the global economic and political theaters; however, searching for an effective and concise measure for efficiency remains a contentious and intriguing topic. There are two obvious flaws with the commonly used metrics in existing literature. First, there is a sense of confusion and misunderstanding between the definitions of energy efficiency and efficacy. As a result, the formulae and methods for measuring efficiency are often the subject of criticism. Second, even if the definition of efficiency is clear, the method of estimation can be q

Abstract:

In paper investigates issues dealing with some aspects of enhancing energy security and increasing energy efficiency. An extensive research related the role of energy in economic life and people’s business activity, as well as, its modern market system being formed as a global commodity was carried out. After analytic generalization, new interpretation of “Energy security” concept was presented. It was clarified once more that, in contemporary world, energy security is measured not only by the quantity of energy consumption supply, but also by its quality values and standards.

Abstract:

Energy-saving hierarchical design model is established for differentiate architecture. From current status of China's construction, exploration research is established on energy-saving hierarchical design model of differentiate architecture to evaluate indicator system of energy-saving building. Availability of evaluation information in index system is low, so it is difficult to play the role of evaluation of building energy-efficiency. EHTV difference method is used to calculate and evaluate energy-saving design of hierarchical building, including: heat transfer indicator of building envelope

Abstract:

Reducing traffic energy consumption is crucial for smart cities, and vehicle carbon emissions are a key energy indicator. Traffic signal control (TSC) is a useful method because it can affect the energy consumption of vehicles on the road by controlling the stop-and-go of vehicles at traffic intersections. However, setting traffic signals to reduce energy consumption will affect traffic efficiency and this is not in line with traffic management objectives. Current studies adopt multi-objective optimization methods with high traffic efficiency and low carbon emissions to solve this problem. How

Abstract:

During the average fifty or sixty years of building lifecycles, large amounts of energies are consumed at all stages, from the production of building materials, transportation for project constructions, daily use, and maintenance to demolition, in particular, the daily energy consumption of air-conditioners, lighting, and elevators. The main “energy saving indicator,” from among nine green building indicators, evaluates the electrical power consumption of air conditioners and lighting. The main evaluation items are building envelope heating load ratio, air-conditioner energy efficiency ratio,

The main purpose of the study is to identify the impact and dependence of socio-ecological and economic indicators on the level of energy efficiency using multiple correlation-regression analysis. The systematisation of the analysed results allowed identifying the core directions to overcome the issues of the slow pace of energy efficiency improvement and the development of carbon neutrality of the country.

Abstract:

The efficiency of urbanization is one of the important dimensions of urbanization quality. From the perspective of environment and resource efficiency, it mainly includes four aspects: land use efficiency, energy use efficiency, water use efficiency and environmental efficiency. This paper, through a review of previous studies and based on the connotations of the four aspects, builds an input–output indicator system with the 2013 data of Chinese cities at prefecture and above levels and evaluates the efficiency of urbanization comprehensively with a single-input and multi-output DEA-BCC model.

Abstract:

Monitoring energy performance can help organizations make better efficiency investment and operational decisions. However, key energy performance indicators can be difficult to interpret because they blend effects of real system changes and statistical model behavior. We designed an explanatory energy model report for a commercial energy-monitoring product. The design was guided by a task analysis based on user observation, interviews, and designer participation. It was refined with usability heuristics, task walk-throughs, and tabletop discussions. Our collaborator is incorporating the design

This paper analyses the main factors affecting China's new energy electric vehicles and their influencing factors. Firstly, it is necessary to collect data, construct indicators, analyse the correlation between indicators, then construct a ridge regression model to obtain the correlation coefficient of each indicator, and finally compare the size of the absolute value of the normalised correlation coefficient to analyse the degree of influence of each indicator. It is found that the development of new energy electric vehicles in China is influenced by four areas: policy, technology, economy an
