A BIM-based method to automate material and resources assessment for the Green Building Index (GBI) criteria

Abstract

Sustainable or green building rating systems were developed in many countries. Green Building Index (GBI) is the rating system developed in Malaysia, which consists of six main criteria. Material and Resources (MR) assessment is one of the main criteria that require the quantification of building materials to calculate the cost of materials and giving GBI points. Conventionally, the assessment process is done manually, which is a time-consuming and error-prone process. Building Information Modelling (BIM) technology gives a new possibility to extracted material quantities instantly from a model, which can support the process of MR assessment. Therefore, this research aims to develop a BIM-MR integration method that integrates the material quantities extracted from BIM with the developed templates and scripts according to the GBI to form automatic assessment results. The prototype system was developed using Autodesk Revit and Dynamo extension, and the validation is done using a case study. With this system, the MR assessment report can be done automatically, which will save time and cost to produce the assessment documents.
