Global warming has changed the climate dramatically, resulting in droughts, floods, and typhoons which endanger mankind’s living environment. Through the many research findings have proven that architectural behaviors have a certain impact towards our environment. Therefore, we have to be more careful regarding architectural behaviors to avoid unnecessary damage to the Earth or mankind’s living environment. This paper focuses on the applicability of green building floor area incentive for urban renewal. It aims at exploring how to cut down unnecessary floor area incentive and energy consumption to lower buildings’ influence on natural environment. Outline of each chapter： Chapter 1 Describe research motive, research objective, scope and content of research, research methods, and procedures. Chapter 2 In the literature review, it focuses on exploring the meaning and purpose of urban renewal, floor area incentive mechanism and theories, and green building’s leveling methods to fully understand the rules of green building floor area incentive and related theories. Chapter 3 It mainly describes the effect on natural environment by growing buildings to explore the connection between the floor area incentive and green buildings. Moreover, it also investigates on how to achieve silver ranking for green buildings in order to get floor area incentive. Chapter 4 Introduce simulated software, Ecotect, suggestions, and procedures about how to conduct this software. Chapter 5 Establish the calculation of environmental load for green building’s floor area incentive and implement computer simulated data for further evaluation. Chapter 6 Provide evaluations and suggestions regarding how to lower the damage to the environment through limiting floor area incentive while achieving the purpose of urban renewal with better living quality.
