Abstract: The improvement of social infrastructure has become a vital topic in Japan. For buildings -- in the view of social energies directed toward the goals of preserving the global environment by means of reduced energy consumption, reducing solid waste and promoting recycling, and planning for continued low economic growth as low birth rates and high life expectancy lead to declines in productivity and purchasing power -- what is required is very durable structures with long physical and social life cycles and that will contribute to a pleasing urban setting.

Up to present time, the average duration of the typical residential buildings has been twenty five years, and about thirty eight years for office buildings (1). In the case of reinforced-concrete buildings, those figures are about half of the legal depreciation cycle (under the Income Tax Law). Currently the breakdown of the national building stock includes about fifty five percent wooden structures, about thirteen percent reinforced concrete structures, and about twenty percent steel frame structures (1). For the future, one hundred-year durability will be needed for each building, whether residences or offices, and regardless of structural type.
A building must have to the primary architectural features of safety and appropriate livability to endure for a long span. Furthermore its materials and elements each has to have the requisite durability, the space must be functional, appealing and fully usable, and the This paper discusses material planning and other issues related to those requirements.
