Incorporating sustainability in construction can result in desirable building attributes and project life cycle. The Leadership in Engineering and Environmental Design (LEED (R)) Rating System helps project teams make the right green building decisions for their projects through a process. However, in current practice, project teams do not have a systematic procedure or tool for choosing the LEED credits appropriate for a particular project. The researchers have developed a tool, which support the LEED integrative process during a charrette, and developed an optimization model that can be utilized to assist project teams determine which credits to pursue for LEED certification, taking into account potential benefits associated with any LEED credit. The tool enables owners to incorporate sustainability in construction by helping the project teams make the right green building decisions for their projects through an integrated procedure.
