Green Building Based On BIM

Abstract

Building Information Modelling (BIM) provides a digital platform for evaluating sustainable design decisions before construction and can be linked with energy-simulation tools to assess operational performance. This study applies BIM to green-building energy analysis using Autodesk Revit for three-dimensional modelling and Green Building Studio (GBS) for simulation after gbXML-based model transfer. The same building model was evaluated at six locations Brasilia, Mumbai, Calcutta, Bangalore, New Delhi, and Shimla to examine the influence of climatic location and sun-path conditions on electricity use, fuel consumption, and energy cost. A 30-year lifecycle period with a 6.1% discount factor was adopted in the source analysis. Annual electricity use ranged from 24,604 kWh in Shimla to 34,206 kWh in Mumbai, while annual fuel use ranged from 119 therms in Mumbai to 298 therms in Shimla. The software-reported annual energy cost was lowest for Bangalore at $2,362 and highest for Brasilia at $4,029. Corresponding lifecycle costs were $32,168 and $54,870, a difference of $22,702. The study demonstrates that building location materially affects simulated energy performance and that a Revit-GBS BIM workflow can support early-stage comparison of sustainable design alternatives, while interoperability, weather-data quality, and occupancy assumptions remain important limitations.
