To improve energy-use sustainability in cities, we proposed a set of urban energy performance assessment indicators and influencing factors based on existing theory and literature. An urban energy performance assessment and influencing factor model was also constructed by the improved stochastic frontier analysis method, and panel data from provincial capitals in China from 2004 to 2013 were co...

This work solves the task of developing a fuzzy logic model for evaluating energy efficiency vehicles as part control unit an intelligent transport system. Within scope this study, previously obtained morphological system was modified. A mathematical dependence is proposed to determine vehicle indicator. characterizes consumption in relation under reference operating conditions. Synthesis confi...

electric vehicles (evs) have gained the attention of many authorities, automakers and researchers due to their considerable energy saving and emission reduction. one of the main issues that must be considered in design of a road vehicle is the calculation of aerodynamic forces. this issue also must be scrutinized in the design of evs. installation of rear spoiler is one of the solutions propose...

e-mail: [email protected] The problem of traffic congestion is particularly acute in urban areas in which the possibilities for the physical increase of capacities are limited or nonexistent. Traffic congestion has a direct impact on the emission, energy efficiency and fuel consumption of personal vehicles. Several projects in the European Union are focused on solving this problem (both at the...

Automated public urban freight transportation networks have the potential to greatly increase the energy efficiency of material transport by more closely matching the mass of the goods being transported with the mass of the transportation apparatus and reduce the cost to society by removing the requirement for human supervision for each package. In this paper, we present an overview of the cons...

Building energy efficiency and urban waste management are two focal issues for improving environmental status and reducing greenhouse gas emissions. The main aim of this paper is to compare economic costs of new building envelope structures designed by authors reusing and upcycling municipal waste in order to decrease energy demand from the building sector and, at the same time, improve eco-fri...

The construction and service of urban infrastructure systems and buildings involves immense resource consumption. Cities are responsible for the largest component of global energy, water, and food consumption as well as related sewage and organic waste production. Due to ongoing global urbanization, in which the largest sector of the global population lives in cities which are already built, gl...

in this research energy efficiency for greenhouse cucumber production in shahreza township located in esfahan province using data envelopment analysis (dea) technique was studied. in this study, data were obtained from 25 randomize active vegetable greenhouses from 60 greenhouses in shahreza township and villages environs. the results showed that the highest and lowest consumed energy were rela...
