A Lean Approach to Enable Sustainability in the Built Environment through BIM

Abstract

Rating systems are assumed as instruments to endorse architectural quality, reliability, energy efficiency, economic convenience and finally expose a sustainability label. Moreover, these tools can be tied to a BIM model. The aim of this research is to set up a lean methodology to fulfil CESBA requirements through Construction to Operations Building information exchange – COBie in project on existing buildings adopting the BIM Bronze approach by UK Ministry of Justice - MoJ. This will allow to develop a semantic model and to extract sustainability reports in a post-construction phase, thereby minimising the cost of gathering information on existing buildings. An illustrated example regarding energy criteria of CESBA protocol will be presented to further the proposed approach.
