Intergrating Building Information Modelling (BIM) and Tools with Green Building Certification System in Designing and Evaluating Water Efficiency of Green Building for Sustainable Buildings

Designing green buildings has become a common trend in many developed countries as a way to promote energy savings and environmental protection. In Viet Nam, the number of certified green buildings remains few, mainly applied LOTUS – the green building rating system introduced by the Vietnam Green Building Council in 2009. It is mainly due to the length of time it takes to design and evaluate green buildings. Applying the Building Information Modeling (BIM) in the design and evaluation of green buildings will address this shortcoming. The integrated BIM-Green Buildings solution kit efficiently provides the architects and engineers with a tool to make preliminary estimation of the green building scoring in term of water efficiency in their design phase; thus they can actively evaluate their performance against key green building criteria and accordingly adjust their designs to meet the criteria at the desired level. This software therefore saves designing time and facilitates the selection of suitable designs.
