Abstract
Various methods of construction should be classified systematically, by being based on the principles. There are several theories as the basis of systematization. "The Control of Active Factors" in which we have concerned, is one of them. Primarily, we picked out "water" from many kinds of active factors. Then, as preparation to systematize the control methods of "water", we showed the system of the aquatic phenomena. They can be classified by being based on water's form, phase and position (in or against the building), whose alteration can also be visualized systematically. According to the theory we made, the aquatic phenomena, which have been considered as unlimitedly various, can be systematized and visualized.
