Abstract:
Green Buildings are gaining popularity in the construction industry as a result of strict environment
protocols and carbon neutral policies by the governments across the globe. In Australia alone, since the
introduction of Green Star Certification 5.5 million square metres of buildings have been certified as green
buildings. With more stakeholders involved, the green certification submission process has become more
complicated with less focus on triple bottom line approach of sustainability. Research has shown that 85%
of the green submissions are concentrated on environmental sustainability with less significance on
economic and social aspects. Building Information Modelling (BIM) is a cutting-edge technology that
allows effective decision making. The proposed research aims to develop a BIM model that can improve the
sustainable decision making during green certification processes. Multi-objective optimisation techniques
were developed to optimise the best design solution for different design criteria. A case study is employed
to verify the functions of the platform suggested in the study. The results of the case study indicated a
combination of green design options provide a maximum of 4.54% GHG emission reduction per unit cost
increase. The outcomes of the research will be important to organizations who are keen on improving the
environmental sustainability while minimising the economic implications.
