By Sandyarani Penta Green building concept aims to reduce the environmental impact of new buildings. A building accounts always for a large amount of land use, energy and water consumption, and air and atmosphere alteration. According to environmentalists, reducing the amount of natural resources buildings consume and the amount of pollution given off is seen as crucial for future sustainability. According to statistics it does not include the concept of renovations although many of the 2050 homes are already built and UK homes account for 30% of UK Carbon Emissions. As per UK Government, domestic energy improvement targets of 20% between now and 2010, and again by a further 20% between 2010 and 2020 . The environmental impact of buildings is often underestimated, while the perceived costs of green buildings are overestimated always. A recent survey by the WBC for Sustainable Development finds that green costs are overestimated. WBC estimate says that it is estimated by by 300 percent. But it needs more investigation and analysis.
