Building production has been studied so far mainly from the standpoints of building designers and constructors, not from the standpoint of the building material manufactures. However, the utilization ratio of industrialized building materials has drastically increased and thus the role of the building material manufactures in building production has become more significant, especially in steel structures. This study looks at building production from the standpoint of a steel manufacture. We present the hierarchy of a building and cases where steel structure supply systems correspond to the hierarchy. We studied the feasibility of each of these cases by conferring with professors, designers, constructors, steel fabricators and steel manufactures.

Long service life, reuse and recycling are counted as three major measures for reducing environmental burden. However, the effects of these measures are not clearly defined, therefore, quantitative evaluation and investigation are required. This study conducts case studies on scenarios presumed for the environmental burden reduction for mid-rise steel building structure. Service life period of buildings, reuse rate of members and recycling rate of materials are considered as parameters. The study pays attention not only to the life cycle CO_2 (LCCO_2) but also to the amount of wastes. Additionally, in seismic areas, if the service life of buildings is extended, risks of large earthquakes increase. Therefore, the case studies assume the seismic design loads corresponding to the service life and calculate the steel weight. Major conclusions obtained in this study are as follows : 1)The environmental burden is reduced by raising the reuse rate of members and recycling rate of materials on stretching service life of the building within about 100 years. 2)Environmental burden does be not evaluated by single measure for evaluation, and it is necessary to carry out the synthetic judgment by multiple measure for evaluation.
