A comprehensive model for wood flows in Japan based on the statistics points out inefficiency that a lot of domestic thinned woods are disposed in spite of the consumption of non-cyclic forest resources from foreign countries for domestic use. Moreover, the model explains that various recycled products made of woodchip would cause decay of flexibility receiving secondary woodchip into the flow. Therefore, new methodologies are required to assess building materials supporting flexibilities of material flows for a dynamic sustainable society as well as existing methods of environmental assessment such as CO2, wastes, and resource consumptions. In existing researches the concept of "a sustainable society" has usually represented "a static society", but a society dreaming of "much more sustainable society" is not necessarily static forever even if material flows look sustainable. In this paper, Aptitude items for a dynamic sustainable society are designed and their effectiveness has been confirmed for assessing wood materials to satisfy these requirements.
