Within the past decade, new building construction in the United States is being affected by the availability of the Leadership in Energy and Environmental Design (LEED). This rating system profoundly alters design and operational issues that include energy and water use, indoor health, recycling for occupants, access to mass transit, materials impacts, landscaping, construction waste management, and maintenance. However, very little is known about the cumulative effects of the rating system across different phases of the project life cycle, such as planning, architecture, engineering, construction and operational facility management (AEC+P+F). As project stakeholders embrace AEC+P+F integration in the quest for improving project performance indicators (e.g., cost, time, quality, etc.), the impact of LEED on this integration, or vice versa, is still unknown. Moreover, the implications of the delivery system in LEED attainment are not clearly associated with the level of AEC+P+F integration. This paper presents the early stages of research focused on determining the associations between LEED criteria, project life cycle, stakeholders and typical delivery systems used in building construction. Results are validated using opinions from experts across the different disciplines in a future study. A matrix of weighted indices is also presented and explained so that increased collaboration may be incorporated into the construction process. The effects of this collaboration on the overall project life cycle, and the association with lean construction (LC) are discussed.
