5 BIM&LEED Greenbuild Europe LEED compliance in the BIM integrated process: How can BIM optimize the design process for Green buildings of the future? How BIM can improve design process and LEED certification: FANUC Italia HQ Case Study. 5

6 BIM&LEED State of the Art BIM is dramatically improving the design of sustainable buildings moving from a manual work to a digital one. But there is still a long way to go: Lack of interface with BIM environment. Inefficient interoperability Unproductive strategy for geometric modeling and environmental simulations Redundancy and loss of information between environmental studies and others 6

7 BIM&LEED Our Goals Foster the interoperability between BIM and sustainable design tools necessary for LEED certification. Develop an innovative simulation workflow aimed at improving efficiency in design phase. Implement a new modeling-simulation process to reduce time spent on 3D geometry and focus efforts on sustainable design. 7
