This paper examines the process of integration of tall building systems with special emphasis on sustainable tall buildings. The design of such buildings warrants a multidisciplinary approach and requires the integration of architectural components, structure, vertical transportation, fire safety, energy conservation, and communication systems. "Technology transfer" is a concept that suggests that technical developments in one industry can be applied to another. Sustainable design of high-rise buildings has benefitted from technology transfers, which contribute new materials, systems, methods, and techniques. Developments in materials, systems, and design integration in the aerospace and automotive industries and lessons learned also can be applied to tall building systems. A major component of the paper entails case studies of buildings, which represent a new generation of sustainable high-rise buildings that are challenging conventional high-rise building practices and setting trends for such future projects incorporating innovations in materials and smart building systems. These buildings are seemingly well-tuned to their climate; and they provide a major portion of their own energy requirements through integrated passive design, daylighting, and intelligent control systems. Special attention is focused on the refinement and further development of an "Integration Web" that illustrates the relationships and interdependence of the physical systems in the design of sustainable tall buildings.
