Optimizing Sustainable Construction Costs: A Green Building Approach for Residential Development

Green buildings are generally referred to as environmental friendly buildings. Globally, building is responsible for a huge share of energy, water, electricity, and material consumption. The green building concept is very popular worldwide. The adverse impact of construction on the environment significantly promotes the development of the green building concept worldwide.The growing awareness of the adverse environmental impacts of construction has led to the widespread adoption of the green building concept globally. This approach promotes sustainability and mitigates the negative effects of construction on the environment. This research project aims to perform the energy and cost saving comparison of green building over the conventional building. Green Building are designed to reduce the overall impact of the built environment on human health and natural environment. This study aims to investigate the cost premiums and cost performance of green building projects. After an extensive literature review and case study of G+4 residential building located at Bhusawal district, Maharashtra has been presented in detail. The land area spread over 6400 sqft and construction area is about 12000 Sqft. and it is designed as per green building design to save the cost and energy for the building. This case study shows that the average increase in the initial cost of green building is 7-10% for those with four-star rating building however 34-40% of energy can be saved by implementing the green building design and technique. This study can reduce the maintenance cost of green building over the conventional building which is very huge amount over the lifecycle of the project.
