Abstract
I investigated the possibility of finding out the potential domestic wood demand on architectural field by using structural lumber and finger-jointed structural lumber for 2×4 construction method, glued laminated timber and cross laminated timber, which are made from board collected from large-diameter log and low grade log, for the purpose of counteracting disadvantage of over grown log and low grade log. The application of board for instant demand increase is for the market of structural lumber for 2×4 construction method. This market has been practically dominated with imported lumber. On the other hand, the application of board for mid-and-long-term demand increase is for the market of mid-to-high rise building. This market has been dominated by non-wooden structural building. In order to boost the demand increase of board, the development of performance based material standard for stimulating to develop new wood based construction material, and the development of quality standard of board for smooth and simplified transaction, are necessary.
