Comprehensive understandings to the built environment especially the urban form is a prerequisite for building a smart city. This paper is based on computational methods to examine the urban fabric of Hankou, China, as a case study. Quantitative and comparative analyses are involved to understand the characteristics on the block scale, where massive demolition and new construction coincide with the...
Sustainable development is among the greatest challenges of this century. Sustainability and development are apparently opposite. The traditional approaches try to manage the planet protection without taking the best from technology while eco-innovation focus mainly on smart transportation, smart use of energy and water and waste recycling. Many new concepts such as Smart, Intelligent, Green or Wise...
Now-a-days all the cities of developed and developing countries feel the need to provide public services in a most effective and efficient way. It is also noted that a considerable number of rural population is converging to the cities to relish the fruits of development and this pace of migration is increasing rapidly. From global experience it is seen that pace of growth of urbanization up to 30%...
Urban logistics is the important foundation of economic, social and environmental coordinated development. Correct evaluation of a urban logistics operation, and establishment of corresponding macroeconomic regulation and management policies is very important to effectively promote the healthy development of urban logistics to ensure the city's economic, social and environmental sustainable development...
Implementing renewable energy resources to enable sustainable development of cities, requires a more flexible and re-silient energy system than currently present. Integrating multiple energy carriers and services allow more efficient implementation of these renewables. Although most research efforts so far have focused on the electricity grid, multi-energy systems attract ever more attention. Over...
The Mumbai Metropolitan Region (MMR), located to the east of the Arabian Sea, experiences tropical climate with annual rainfall of over 250 cms. Geographically, the Thane Creek separates the island city from the mainland comprising low-lying marshy lands, and is lined by north-south trending hills on either side. The Creek has historically served as the natural course for rainwater discharge from...
Xi'an is in a critical period of urbanization. Thequantitative assessment of renovation sustainability of """"cityvillage"""" provides a theoretical basis for the sustainabledevelopment monitoring by the city government and theurban development planning. According to the connotationof sustainable land use and combining the characteristics ofurbanization in Xi'an,...
To evaluate the development of 9 provinces (or cities) of China, we analyze the relative advantage of different provinces ities) from four aspects: economy, society, sustainable development and politics and culture. Considering the difference of resource of rent provinces (or cities), we provide a new evaluation model. Specifically, first, the provinces (or cities) are divided into three regions,...
In this work a typical meteorological year (TMY) data sets for 20 solar radiation monitoring stations in Thailand were generated by using the Sandia National Laboratory method. A 10-year period of hourly global solar radiation, air temperature, relative humidity and wind speed from these stations were used to generate the TMY data sets. To investigate their performance, the TMY data sets were employed...
Megacities in India are historically the major economic growth centers and Kolkata is the oldest and the most densely populated mega city. An assessment of sustainable development challenges and possible green growth strategies give rise to some interesting insights that are generalisable as well. Sustainable development priority assessment for Kolkata district brings forth the issues which go beyond...
Technology to abstract energy from the wind using Vertical Axis Wind Turbines (VAWTs) has rarely been adopted for large scale power production, owing to low power coefficient of the individual turbines, as compared to Horizontal Axis Wind Turbines (HAWTs). In the last few years, much research has been done to make VAWTs more economical and efficient to increase power generated per turbine. But besides...
As a move towards sustainable low carbon growth, there are number of mitigation measures like energy efficiency, fuel switch, technologies and demand management which have been identified to reduce green house gas emission. The major reduction opportunities of GHGs involve improving the efficiency with which the energy is used and the transition towards alternative sources of energy. The sustainable...
An energy efficient household is one of the solutions in the approach to create a green society because the quantity of electricity being consumed in households is rapidly increasing. In this paper, we report on the implementation of an electricity consumption metering and online visualization system installed in 30 households with the objective of encouraging behavioral change. The system provides...
Pakistan is facing severe energy crisis even having a great potential of renewable energy resourcesespecially solar energy. Pakistan has~2.9 million MW potential of electricity generation using solar energy (PV) which is hardly exploited. Current articleis focused to analyze the implementation of solar photovoltaic for the domestic sector of Pakistan where blackouts of 6 to 7 hours are common. Current...
Transport sector's fuel mix which is dominated by the fossil fuel imposes multiple external costs like energy security, air quality and climate change. In this study, alternate future scenarios are designed to explore the transitions of national transport system (till 2050). Several policy options are delineated that would facilitate the sustainable low carbon transformation of India's transport sector...
Effective measures against global warming must integrate both mitigating and adaptive strategies. Accordingly, this study aims to develop information systems adapted to flooddamage, such as electricity infrastructures, by using green energy in urban areas. Rapid urbanization has caused significant increases in heavy rain; therefore, people in flood-risk areas need risk information, such as precipitation...
In electric drive applications, the conventional carrier based and space vector pulse width modulation (PWM) which schemes for two-level inverter topology generate large common-mode voltages, this leads to the phenomenon of bearing current. These current spikes can cause electromagnetic interference (EMI) and reduction in the life expectancy of the motor. Cascade multilevel inverters can reduce voltage...
Food waste contains a substantially large amount of organic matter, which can be digested anaerobically to produce biogas. In this present study, biogas yield of food waste was evaluated in a laboratory scale anaerobic batch reactor. The effect of solid concentrations (5, 7.5, 10, 12.5 and 15%) on the yield of biogas was investigated at mesophilic temperature condition for a hydraulic retention time...
