The sustainable infrastructure is the need of the next generations. There is no definite tool to give exactstreamlined decision for the feasibility of the any project. Day by day, the depletion of environment due to constructionactivities is increasing. A solution to these crises is the construction of green structures which have minimal impact on theenvironment. In this process of shifting from conventional to green structures, the initial investment cost of the projectmay tend to rise higher, however, the entire structure gives huge returns over a period of 10-15 years due to which thisshift can prove to be beneficial. The purpose of this paper is to highlight the role of life cycle cost (LCC) analysis in thefeasibility study of construction projects and in deciding on the proposals of infrastructure projects. A study was made onthe cash flows during the construction and further the expected returns were calculated. The results obtained, highlightthat the factors like construction techniques, materials, etc. influence the cost of a green building. Therefore, after athorough study of costs incurred and the future benefits and further the analysis of life cycle cost, we can state thefeasibility of a green infrastructure project. Thus providing an alternative approach as to how to achieve long termminimum value of total costs from strategic point of view.
