A comparative study of the economy and the labor on-site of ALC (Autoclaved Lightweight Concrete) curtain wall system, HPC (Hshaped steel and precast concrete pannel) system and PC (precast concrete) pannel system, which are suitable for the prefabricated school systems, are made with brief structural calculations and cost estimates. If 4-story schools are compared, the PC pannel system is 20% more expensive in comparison to the conventional concrete construction. And the ALC curtain wall system and the HPC system are approximately twice as much as the conventional method, The unit of labor on site, however, will be less in an order the conventional method, the ALC curtain wall system, the HPC system which is most prefabricated; therefore saves 35% labor on site in comparison to the conventional method. With the change of education system which is apparant, the space and the use of classrooms will eventually change from the present standard. Rather than designing fixed classrooms whith the antiseismic wall like Type I, free open classrooms like Type II will be more adaptable to the future education. From the educational and structural points of view, it is worse push forward the application of the ALC curtain wall system and the HPC systems of Type II as the future school building structures rather than cheaper PC pannel system of Type I.
