6D Bim for Sustainability Analysis: A Conceptual Model for a Typical Residential Building

The primary focuses of today’s world are: How to create energy-efficient buildings? How to design high-performance structures? How to achieve sustainability in construction? The answers lie in Building Information Modelling (BIM) and its 6D capabilities for energy efficiency and sustainable analysis. This research aims to gain a deeper understanding of energy consumption by analyzing the sustainability of a residential building in Dhaka, Bangladesh, using BIM tools such as Autodesk Revit 2020, Autodesk INSIGHT360, and Green Building Studio. The building’s energy model will be developed in Autodesk Revit in accordance with ASHRAE Standard 90.1 for Zone 1A, with energy simulations performed in Green Building Studio and Autodesk INSIGHT360. The study incorporates energy savings, cost efficiency, compliance with BNBC codes, literature reviews, and Bangladeshi design practices to evaluate sustainability. Based on the findings, the research identifies the most optimal Autodesk INSIGHT360 building parameters from a Bangladesh perspective, achieving a 7.2% reduction in Energy Use Intensity (EUI) compared to the ASHRAE-90.1 benchmark for a Dhaka-region building.
