Abstract
The concept of sustainability has gained popular momentum over the past twenty years in the construction industry. To achieve the goals of sustainability in the construction industry, sustainable design and construction strategies have been developed and implemented into buildings over the building's life cycle. These sustainable strategies also have incorporated into tall building design, construction and operation to minimize environmental impacts; save water and energy consumptions; and provide high quality indoor environment to not only improve occupants' health and wellbeing but also to increase their productivity. Due to many potential benefits related to sustainable tall building design, several tall buildings in the United States have incorporated sustainable strategies in their new development and major improvement. This study identifies sustainable design strategies relate to energy efficiency along with their potential benefits from the implementation of sustainable strategies. This study studied for sustainable tall buildings including the The Empire State Building, the Willis Tower (formerly Sears Tower), the Bank of America Tower and the Duke Energy Center located in the United States. By conducting case studies for four sustainable tall buildings, it is possible to identify and compare sustainable strategies, mainly related to energy efficiency in sustainable tall building. This study suggests potential sustainable strategies for the renovation of sustainable tall buildings and new sustainable tall buildings in the Republic of Korea.
