Retrofitting of Existing Building Aiming Leed Certification using BIM

Abstract

LEED, or Leadership in Energy and Environmental design, is the most widely used green building rating system within the world available for nearly all buildings, community and residential project types. LEED provides a framework to form healthy, highly efficient and cost-saving green buildings. LEED certification is a globally recognized symbol of sustainability achievement. Instead of targeting new buildings this research aims to find the optimal retrofitting solutions for existing building keeping in mind the cost and availability of products in Pakistan. An educational institute in NUST was chosen, and the methodology used involves simple understanding of LEED v4 (BD+C) and involves softwares such as Autodesk REVIT 2017 and manual calculations. The retrofitting solutions proposed in this study can be used to achieve Silver category of LEED certification for case study building.
