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
Monthly-averaged daily global irradiation data are now easily available from
NASA website for any global location. Using established models it is then
possible to decompose the daily to averaged-hourly global irradiation. The
missing link so far has been hourly averaged diffuse irradiation. In this
article data was pooled from 14 world-wide locations to obtain a regression
model to complete the ab... 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

The building sector accounts for around 40-50 % of the energy consumed in
developing countries and contribute over 30 % of CO2 emissions. In Cameroon, the
electricity access is less than 5 % in rural areas against 50 % in urban areas.
All sectors combined the Cameroonian final energy consumption amounts to
approximately 5235 kilo-tonnes of oil equivalent (Ktoe) and 73 % of this energy
are assigned... hiện toàn bộ

The planned energy-efficient retrofitting of a residential building in Bologna,
North-Center Italy is presented. The building is a detached house with an
unheated basement, three floors with 2 apartments each, and an unheated attic.
The total heated floor area is 281.9 m2. The external wall is made of solid
brick masonry and most windows are single glazed; no thermal insulation is
present. Space h... 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
More than half of the world’s population currently lives in cities. An essential
constituent of future sustainable cities is energy efficient and ecologically
sound buildings which ensure high levels of comfort and convenience without
reducing the standards of living. At present, a significant part of primary
fossil fuels is spent for heating/cooling of buildings, thus, greatly
contributing to tot... hiện toàn bộ
