| Abstract |
Amidst growing concern about the sustainability of human society, architecture studies are focusing increasingly on the means to achieve sustainable buildings. While various forward-looking studies are ongoing in this field, it is also important to realize that critical lessons may be learned from historical buildings that have withstood the test of time. Many traditional wooden buildings in Japan provide excellent examples of sustainable building design and production practices that are inherently flexible and therefore highly resistant to obsolescence. This paper first summarizes a recent lecture by Utida outlining his research into the flexibility and durability of modern buildings, which is based on comparisons with Japan's traditional wooden buildings. It is based on the results of Open Building researches in Japan, especially works in Utida laboratory of Tokyo University (1970-1986) and in All Open Building Sub Committee. This is followed by an overview of the flexibility and material/social lifespan of buildings, and of the developmental trends seen in builders' organizations. And lastly, the future direction of the Japanese detached housing industry is explored. Specifically, the paper traces the changes in the Japanese detached housing industry between 1970 and 2070, and shows how the industry has been shifting toward a sustainable business model. Problems arising from these changes and possible solutions are discussed with concrete examples, and one specific business model is singled out and defined as a promising solution. |
