Hanok has been an exception of building energy conservation in the reality of trying to save energy for buildings. But this issue for hanok can no longer be left unattended by international efforts to prevent global warming.
Therefore, this study researched first, how highly efficient insulations can affect insulation properties when applied to walls in order to quantitatively grasp the energy performance of hanok, and second, how to supplement insulation and airtightness by finding areas vulnerable to insulation in structure.
The results of this study showed that because the ratio of insulation walls about composition of wall is low, and many heat losses occur in the contact areas of each laminated timbers. Thus, it is effective to increase the ratio of insulation walls with using high efficient insulation materials suitable for the site situation and to cut off heat bridges in the laminated areas where linear heat bridges occur.
