CBD is the economic center of Japan. Therefore, in case of disaster, the demand for high level of sustainable business with continuity is considerably strong. Instead of individual frame structure, buildings are designed for strengthening each other as an integrated system. This relationship, known as ‘collaborative assistance’, consists the overall planning of disaster prevention as well as the sustainability of business. The ' post-disaster support base ' should be introduced as the centric function. In this research, we construct evaluation method for disaster functional buildings, based on an analysis focusing on different phases of disaster prevention and the correspondence range, in aim to specify the proper prevention strategies. In the future, this type of evaluation will be implemented on all developments in CBD such as Otemachi, Marunouchi, and Yurakucho area in Tokyo.
