Assessing the Applicability of Green Building Information Modelling for Existing Green Buildings

Abstract

Green Building Information Modelling is a novel approach which address the momentous need of sustainability. It offers more standardized way of creating buildings which in turn optimize the building performances while attending to the sustainable requirements. Comprising numerous techniques, Green BIM ensures more accurate and comprehensive building performances to optimize the energy efficiency of buildings. Thus, there is a considerable advantage to create more energy efficient buildings using Green BIM. However, the use of Green BIM for existing green buildings is very less while new green buildings are managed using Green BIM. Hence, this research focused to assess the applicability of integrating Green Building Information Modelling for existing green buildings through a practical implementation and identifying the potential challenges. Conducting a comprehensive literature survey first, Green BIM techniques and data requirements of Green BIM were reviewed. A single case study was conducted next, to practically apply the Green BIM technology. The data requirements for Green BIM were identified prior to the selection of case for the study. A questionnaire survey was conducted to analyze the data availability including the data identified from literature. Analyzing the survey findings, an existing green building was selected and finally, the steps to be followed for the use of Green BIM were established. The challenges of the implementation were also presented in this study. The findings proved that; Green BIM is a potential technology for the existing green buildings.
