Paper Title
Sustainable Approach for Building Materials and Airflow Analysis for Elevated Metro Rail Station Box of Ahmedabad

Abstract
• Purpose - Building Information Modelling has been effectively utilized for energy modelling and analysis widely in the design phase for the complex infrastructure projects. The purpose of this study is to identify and analyse the embodied and operational energy demand of the elevated metro rail station with respect to alternate designs and building materials. • Design/methodology/approach - The total amount of energy consumption of the elevated metro-rail station in Ahmedabad, India, and its annualwind analysis. Evaluation of the alternative building materials and designs to obtain the best in class energy requirements by using Autodesk Revit Architecture 2018 and Green Building Studio. • Findings - The findings suggest a different set of building materials and sustainable designs leading towards the reduction in the embodied and operational energy consumption through its whole annual life cycle. • Originality/value -This work enlightens the significant energy savings in terms of embodied and operational energy by using BIM as a sustainable approach for the elevated metro rail station. At last, recommending few alternate building materials and sustainable designs resulting in the reduction of energy usage up to a greater extent for energy-efficient metro rail station leading to a sustainable future.
