Interactions of Sustainability and BIM in Support of Existing Buildings

Based on the previous studies, the majority of the energy consumption utilized by the building sector and the most significant part of power distributed by existing buildings. One way to improve and monitor energy efficiency in existing buildings is to use sustainable development assessment methods. This study aims to improve the process following these steps: (1) provide a concise review on the most recent papers concerning sustainability in design and construction, sustainability in existing buildings, and BIM-based methods which published in peer-reviewed journals and international conference papers to ascertain the status of this research area. (2) Present a BIM-based sustainability model to target existing building projects. (3) Finally, the benefits and barriers of the model for the design team, construction managers, and owner highlighted. This paper provides a roadmap for future efforts toward implementing BIM and Sustainability for existing buildings.
