Comparative Study and Cost Analysis of Green Building and Conventional Building (Case Study) - A Review

Conventional buildings have major environmental impacts during their life inclusive of their construction phases. Resources such as ground cover, forests, water, and energy are dwindling to give way to buildings. Resource-intensive materials provide structure to a building and landscaping adds beauty to it, in turn using up water and pesticides to maintain it. Several building processes and occupant functions generate large amounts of waste, which can be recycled for use or can be reused directly. Buildings are thus one of the major pollutants that affect urban air quality and contribute to climate change. Hence, the need to design a green building, the essence of which is to address all these issues in an integrated and scientific manner. A green building depletes the natural resources to a minimum during its construction and operation. The aim of this project is to give the importance of green building design is to minimize the demand on non-renewable resources, maximize the utilization efficiency of these resources when in use, and maximize the reuse, recycling, and utilization of renewable resources. The study is focused on maximizing the use of efficient building materials and construction practices; optimizes the use of on-site sources; uses minimum energy to power itself; uses efficient equipment to meet its lighting, air conditioning, and other needs; maximizes the use of renewable sources of energy; uses efficient waste and water management practices; and provides comfortable and hygienic indoor working conditions. A green rated building and its features are selected for comparison with conventional type of building features which gives us the user benefit comparison and in some context of cost variations.
