Abstract: While the need for sustainable practices in building projects is globally recognized, some construction stakeholders still demonstrate resistance in adopting sustainable practices. The general perception is that attempting to achieve sustainability will increase the capital cost of construction and can delay the schedule. In recent years, societal pressure and government incentives as well as practitioners knowledge and acknowledgement, have led many construction projects to pursue sustainability credits. In 2002, Canada Green Building Council (CaGBC) adopted the Leadership in Energy and Environmental Design (LEED) standard as a tool to evaluate the sustainability of construction projects. The main objective of this research is to generate a better understanding of LEED professionals’ perception of the impact of achieving LEED credits on projects parameters such as cost, schedule and future value. A survey was conducted to clarify their position towards the impact of each of the 69 points in the early version of LEED-New Construction on project factors. The survey targets factors in its three phases — prior to construction, during construction and post construction. The results can assist in improving the evaluating systems and developing sustainability design tools in the future.
