Exploring the factors that affect energy supply and demand is the basis of solving energy problems. And the influence of urban form has brought widespread concern. However, the complex role of urban form indicators is not clear, and the influence mechanism of urban form on overall energy consumption and energy supply capacity needs further discussi...

A key strategy for lowering emissions and reducing the effects of 11 climate change is to execute energy-saving retrofits in residential buildings. Despite 12 extensive research on different retrofit pathways for building energy efficiency, the 13 current retrofitting of the aged housing stock in China is still constrained by several 14 factors, in...

Flooding is a serious challenge that increasingly affects residents as well as policymakers. Many studies have noted that decreasing the urban flood vulnerability (UFV) is an indispensable strategy for reducing flood risks; however, some studies have several pertinent assessment limitations. The objective of this study is to assess the UFV of the X...

Land use changes have a considerable impact on ecosystem services (ESs). In recent years, land use changes caused by urban expansion in Nanjing City have been obvious and are expected to further change in the future. Therefore, it is urgent to quantitatively assess ecosystem service values (ESVs) changes caused by previous land use changes and futu...

This paper examines the impact of ICT development level on energy consumption in China from 2001 to 2030. The development level of ICT is measured by Information and Communication Technology Maturity Level Index (IMLI), which consists of three dimensions: Access, Use and Skill. Energy consumption is divided into four categories: data centers, commu...

Energy-saving reconstruction of old residential buildings is a vital way to achieve sustainable development, but the potential of rooftop photovoltaic (PV) energy-saving in old residential buildings has not been studied. This study established a basic framework for the estimation of rooftop PV technical, economic and environmental potential in the...

The vigorous development of renewable energy is an important way to achieve carbon neutrality in China, but the water and electricity consumption of renewable energy in its life cycle is still unclear. This study took the life cycle of photovoltaic (PV) industry as an example, combined the life cycle assessment method, Weibull model and water resou...

Increasing temperatures in urban areas have brought about a series of prevalent environmental and energy shortage problems. Many studies have focused on the relationship between land use-cover change and land surface temperature (LST), and the effect of LST on energy consumption. The objective of this study was to identify the relationship among la...

Increasing urban flood posed serious threat to urban safety and sustainable development, and resulted in great loss and damage. It was significant and indispensable to master the potential change of urban flood for flood risk mitigation and adaption. Floods not merely caused the physical losses, but also led to potential damage and harm during floo...

Flood is a serious challenge that increasingly produce immense economical and ecological damages in worldwide. Flood simulation is gradually becoming a central focus of the hydrology in recent years. It is worthwhile to combine flood simulation with flood damage to infrastructure. The purpose of this study is to develop an approach for better urabn...

Buildings have a significant impact on global and local energy demand and climate change. Consequently, the issue of photovoltaic (PV) potential assessment of building roofs have been extensively studied. Although studies have adopted different methods to predict the various potentials of rooftop PVs, as yet there is no understanding of a comprehen...
