Urban and building energy simulation models are usually driven by typical meteorological year (TMY) weather data often in a TMY2 or EPW format. However, the locations where these historical datasets were collected (usually airports) generally do not represent the local, site specific micro-climates that cities develop. In this paper, a humid sub-tropical climate context has been considered. An ide...... hiện toàn bộ
Solar panel conversion efficiency, typically in the twenty percent range, is reduced by dust, grime, pollen, and other particulates that accumulate on the solar panel. Cleaning dirty panels to maintain peak efficiency, which is especially hard to do for large solar-panel arrays. To develop a transparent, anti-soiling Nano-TiO2 coating to minimize the need for occasional cleaning is the purpose of ...... hiện toàn bộ
Năng lượng là yếu tố không thể thiếu cho mọi hoạt động của con người. Giao thông, sản xuất công nghiệp, thương mại, truyền thông, v.v. phụ thuộc vào khả năng cung cấp năng lượng. Truyền thống, người tiêu dùng đáp ứng nhu cầu năng lượng của họ bằng cách mua điện và nhiên liệu từ các công ty phân phối. Đối với việc sản xuất năng lượng điện mà người tiêu dùng tiêu thụ, một phần lớn được sản xuất tại ...... hiện toàn bộ
As one of the most energy-, emission- and pollution-intensive industries, iron and steel production is responsible for significant emissions of greenhouse gas (GHG) and air pollutants. Although many energy-efficiency measures have been proposed by the Chinese government to mitigate GHG emissions and to improve air quality, lacking full understanding of the costs and benefits has created barriers a...... hiện toàn bộ

Urban growth management has become a common term to circumscribe strategies and tools to regulate urban land use in metropolitan areas. It is particularly used to counteract negative impacts of urban sprawl but also to frame future urban development. We discuss recent challenges of urban growth in 6 European and 2 US American city-regions. The paper compares the urban development focusing on a qua...... hiện toàn bộ
This paper endeavours to understand the climate change phenomenon and identify measures taken to contain it. It discusses global warming causes and consequences and assesses effectiveness of the United Nations (UN) polices following failure of the Kyoto Protocol to reduce greenhouse gas emissions. In pursuing this course of action, this paper utilizes data collected from East Africa region. Key is...... hiện toàn bộ
India is known to emit large amounts of black carbon (BC) particles, and the existing estimates of the BC emission from the transport sector in the country widely range from 72 ~ 456 Gg/year (for the 2000’s). First, we reduce the uncertainty range by constraining the existing estimates by credible isotope analysis results. The revised estimate is from 74 ~ 254 Gg/year. Second, we derive our own BC...... hiện toàn bộ
