Integrating BIM with Energy Analysis and Green Building Certification System to Design Sustainable Building

According to smart city studies by the Irish multinational Johnson Controls, just 4% of buildings in India can be classified as “green.” Building professionals are getting more and more interested in designing eco-friendly buildings that offer superior performance and cost advantages. For building materials to qualify for green building certification, energy efficiency is a key criterion. There are currently capabilities in building information modeling (BIM) tools that enable users to consider various energy-saving tactics at an early stage of energy analysis. BIM technologies give owners and designers the ability to make energy-related decisions early in the design phase that have a substantial impact on the overall expenses of a potential project. A 3D BIM model in Autodesk Revit must be generated to run the energy analysis in Autodesk GBS and assess the results of the base-run construction’s EUI, U-value, and SHGC Value. The EUI value for a commercial building is 1113.1 MJ/m2/year. The criteria of LEED, IGBC, and GRIHA were analyzed and comparative analysis was carried out.
