Tall buildings emerged in the late 19th century in U.S.A. to meet the growing demand for inner city office space and today they have become a world-wide phenomenon. Tall buildings were made possible by such innovations as the electric elevator, advances in structural steel making, and advances in heating, ventilation, air conditioning and electrical systems.In this paper, energy evaluation systems in buildings such as; BREEAM, LEED and PEARL was studied And the main factors in this field that are effective in sustainable design of tall buildings were identified.The earlier view of tall buildings as large scale energy consumers with little regard for sustainable architecture is now changing. The new generation tall buildings are being designed with energy conservation and sustainability as their principal criteria.Increased emphasis on the use of green and sustainable building materials and technologies is creating a paradigm shift in the way the new generation tall buildings are being designed. Energy efficiency has become the core issue for the acceptance of any design solution that advocates long-term economy.Many iconic tall buildings across the world are being retrofitted for energy efficiency and they should serve as role models for tall buildings across the world. The application of green technologies in tall buildings can accelerate our march towards sustainability
