This study is Korean traditional heating system, named 'AZABANG'. Ondol characterized by" Azabang "is dated back to 119 AD and it has approximately 2000 years history. Among various kinds of traditional radiant floor heating system, Ondol is the most reasonable and scientific one. This type of imaginative Ondol which have superior ability to keep temperature during a long period, roughly I 00 days could be attributable to the special structural pattern . The Ondol characterized by ''Azabang" represents extraordinary creativeness originated from Korean traditional culture and at the same time, it is the significant evidence that those missing historical rings, in some degree, have been connected. Therefore we well do our best to apply the scientific and reasonable concept into the real world.
