Green Building Construction

Construction industry is one of the largest consumers of raw material and energy during its lifecycle and therefore has a profound impact on environment. Buildings not only protect us from extremes of nature, but they also affect the natural environment, human health and the economy. For example, to heat/cool and power our buildings, large amount of energy is consumed. This energy is obtained primarily by burning fossil fuels - oil, natural gas and coal – which generate significant amounts of carbon dioxide (CO₂), the most widespread greenhouse gas (GHG). With modernization, environmental impact of buildings is becoming more apparent. Buildings may be associated with the release of GHG in other ways, for example, construction and demolition debris that degrades in landfills may generate methane, and the extraction and manufacturing of building materials may also generate GHG emissions.
