Major prefabricated houses manufacturers started their business around 1960s and became world class large housing companies. This study clarifies 9 major prefabricated houses manufacturers' developments at early stage by interviews with their in-house engineers and architectural designers as well as analysis of relating documents. Early prefabricated houses were developed by small number of engineers intensively. Various architecture and specialists including foreign architecture, famous architects and academics affected these developments in some aspects. Furthermore, each of early prefabricated houses had many unique characteristics in building systems. Some of them had changed in early stages, while the others still remain nowadays.

The Housing Loan Corporation founded in 1950 was the most powerful supplier of public houses in Japan, which financed the enormous amounts of the Government Housing Loan for Japanese people during the latter half of the 20th century. For instance, approximately sixteen million housing units financed by the Housing Loan Corporation were built from 1966 to 2000, and accounted for about seventy percent of public houses. This research aims to clarify how the Housing Loan Corporation had improved the quality of Japanese houses. To verify the promotion of prefabricated houses by the Government Housing Loan, this paper carries out two approaches: one is to compile the statistic of it and the other is to make a historical review based on the examination of the Housing Loan Corporation's business plans during fifty years. And the followings are clarified. The course of the Housing Loan Corporation's history was to make a variety of loans to the dwelling units for sale. When the Government Housing Loan started in the early 1950s, the customized houses accounted for above ninety percent of the owner occupied dwellings and most of it was loaned to them. But the loans to the dwelling units for sale occupied almost fifty percent of it in the late 1990s. Because the more they were built in Japan, the more the Housing Loan Corporation loaned to them. This suggests that the system of the Government Housing Loan accommodated itself to structural changes of housing market in Japan. The Government Housing Loan to wooden prefabricated houses and steel made a substantial contribution to Japanese houses. The former, based on Agrément on Factory-made Houses since 1966, made an origin of seismic and fire preventive performance with current wooden houses of Japan. The reason is that it grew a structural planning method based on the bearing wall line and a specification of quasi fire resistive construction with wooden materials, which are generally used in designing conventional houses today. In contrast, the latter, started in 1962 as part of noncombustible building policy, seems not to bring anything of technical development. But the Government Housing Loan gave the steel prefabricated houses a quality assurance on new building system, and became the start of spreading tie-up loans in detached houses of Japan. Nowadays steel construction houses occupy approximately twenty percent of Japanese housing market and distinguish it from other countries'. In Europe and America, the purchasers of steel prefabricated houses weren't loaned generally by any financial institutions. This is pointed out to be one of reasons why they didn't take roots there. Therefore, the Government Housing Loan to steel prefabricated houses can be said to become the start of making an identity of Japanese housing market.

This paper is a study on the imports of building materials and components in Japan. The followings are shown by analyzing both domestic statistics and Trade statistics: firstly, changes in the import quantity and rate of eighteen building materials and components from 1971 to 2016 are classified into four types. Second, the import rate of seven materials are higher than 10% nowadays. Third, the increase of the import rate has been basically caused by the globalization from the early 1990s, although the resource nationalism and the growth of Korean industry increased the import rate of same materials in 1980s.

This paper is a study on renovation to make a new skin on building envelope by dry method. The discussion about countermeasures how to fix fall troubles of external finishing which covers GRANDSHIP in Shizuoka City is examined as a case study, the followings are pointed out: firstly scope of consideration to add a new skin to existing envelope is clarified. Secondary the risks of modifying works to envelope are categorized to two types: one can avoid them by modifying design, the other can’t. Finally the process model to compare means of renovating building envelope is proposed.

The scope of education on building technology is not limited to construction supervision for architects and construction work management for constructors. In fact, when the 2008's reform of the Architect Act introduced the eight categories of designated lectures in accreditation of architect license in Japan, one of them was Building production, not Construction work. However, architectural courses of technical colleges and universities do not necessarily have the common understanding on education of building production. This paper is the third report of educational report series to facilitate richer education of building production in technical colleges and universities. By a review to nine textbooks of building production and a questionnaire survey to two hundred forty two departments of architecture, which the former two reports showed in detail, we made out the reference material for syllabus on lectures of building production. That contains a list of ninety-three educational headings of building production, two tables of three lecture types related to educational headings or construction business fields, variations of each lecture type on procedure, and instances of typical lecture procedure. This paper aims to evaluate the reference material for syllabus, and to discuss the future lectures and texts of building production. A new questionnaire survey to ninety-six departments of architecture has made the followings clear. Firstly, the reference material for syllabus is useful for revising syllabi on lectures of building production. Especially by the list of educational headings of building production, almost lecturers of all lecture types will check whether their lectures have enough educational contents or not. Moreover, the lecturers of lecture type II are able to add educational issues to their lectures based on the table of construction business fields, and the lecturers of type III are able to build up a new lecture scenario by referring to the variations on lecture procedure. Secondary, educational issues how to use existing buildings will become more important in future lectures of building production. Since two thirds of lecturers intend to add these issues in their lectures, that includes thirty percent of lecturers of type I although they scarcely give a lecture on the use of existing buildings. There is another approach to enrich the education on the use of existing buildings. That is to start a new series of lectures. In this case, lectures are necessary to have educational issues on renovation, facility management and real estate at least. Finally, future texts of building production should contain figures and tables that are suitable for projection in lectures. According to our questionnaire survey, lecturers of building production in technical colleges and universities point out luck of such educational materials. On the other hand, researches on building production have shown their results by various diagrams, which represent relations of construction subjects or processes of construction site works. In order to increase educational effectiveness, future texts are necessary to develop much simpler diagrams than the originals made by researches of building production, and to collect them in themselves.

This Paper discusses the possibilities and contributions of establishing 'design-oriented components', which provide flexible design for the A/E, and concludes follows. 1. The production system of component manufacturers has enough flexibility to accept special orders from the A/E since they have changed from production for stock to that for order. 2. There is no reason why the A/E selects ready-made components only for his design, nevertheless the idea of open system has been based on such components manufactured by the production system for stock. 3. It is essential to establish design-oriented components with which their information is represented by a means of operating their attribute easily. Such components are expected to gather A/E's needs for new developments by component manufactures.
