The paper is developed to assess various glass type and their effect on building energy. Consumption. The research will help to understand the effect of types of glass considering its parameters which are VLT (visual light transmit) and SHGC (solar heat gain coefficient). The analysis is done to see effect on energy consumption by changing glass type firm single to double to triple glazing. The analysis is done with the help of BIM software Autodesk Revit with Insight plugin. Use of various types of glass is used. The study is limited to commercial building with G+5 floors located at Ravet. Also, to study varying WWR (window to wall ratio) to varying glass types is done. This paper seeks to integrate the use of BIM based energy analysis in predicting the energy consumption of a Library building.
