Sustainable Construction

The Paper is about the Sustainable Construction which doesn’t cost anything extra infact it has overall saving and less costlier with many Eco-friendly Benefits. The Paper revolve about the Cost associated with the Sustainable Construction and comparison with the Conventional Construction. As the Cement and Supplementary Material plays the vital role in the Green Construction the paper represents the future ahead. As Buildings are among the greatest consumers of energy and have major environmental impacts over their entire life cycle this paper mainly emphasis on the Building Construction. Building account for 40 Percent of the World’s energy use and 48 percent of Green House Gas (GHG) emission contributing to global climate change. The Paper refer to all building material used for building construction with respect to cost and availability of the material. The Paper is trying to bring awareness with respect to costing and remove the perception that the sustainable construction comes with higher cost which is absolutely incorrect. The need of hour is the basic knowledge about the Sustainable Construction and baseline cost working. The awareness on using of available materials and technology plays an important role in increasing or decreasing the cost of green building. The Sustainable Construction and cost associated with it, is a wide subject hence through this paper we have tried to highlight Construction Material Cost which cost around 60-70% of the total Project Cost. The certification of Sustainable Construction is also very easy. If proper planning is done during the design/concept stage each and every building can be Certified Green Building and Sustainable building.

Introduction
India’s construction industry, one of the largest contributors to the economy, is also contributing to the degradation of the environment. Buildings alone are responsible for at least 40 percent of energy use in most countries. The absolute figure is rising fast, as construction booms, especially in countries such as China, India and the southern Mediterranean countries. The household sector is the single-largest consumer of energy in India, accounting for 40-50 percent of the total energy consumption. In rural areas, the residential (domestic sector) accounts for nearly 80 percent of the consumption of energy. The resulting carbon emissions are substantially more than those in the transportation sector. Sustainable development is defined as ‘Meeting the needs of the present generation without compromising the ability of future generations to meet their needs.’ (Brundtland 1987).

New buildings that will use more energy than necessary are being built every day, and millions of today’s inefficient buildings will remain standing by 2050. However, these green buildings constitute only two percent of the number of total buildings in the country. It is estimated that in a typical residential building, around 28 percent of the total electricity is consumed for lighting, 45 percent for air conditioning, 13 percent for refrigeration, four percent for televisions and 10 percent for other appliances in the urban sector. Therefore, it has become increasingly necessary to make appropriate efforts to bring down carbon emissions from the building sector. However, these green buildings constitute only two percent of total number of buildings in the country. Global warming can cause a 20% recession in the world’s GDP as this phenomenon increases the possibility of occurrence of natural disasters altering the world’s GDP.

A look at conventional building systems in India clearly demonstrates that the model of sustainable buildings has existed historically for a long time. These sustainable buildings were typically made of locally available materials like timber, mud and stone dealing with the vagaries of nature, without using a large amount of outside energy to keep the inhabitants comfortable. There are several papers and information about the Sustainable Construction and about Green Building that is nothing new in India. But still we find very less Green Building being constructed across India with respect to the present construction going on and in pipeline. Here through this paper we shall discuss about the Material involve in the Green Building and associate cost and compare it with the Conventional Construction Material.
