Abstract
The purpose of this paper is firstly to clarify the role of Ondol-ban (a room with floor heatings) and Maru (a room with wooden floor and large opennings), and secondly to classify the plans of traditional Korean houses from the viewpoint of indoor climate control. The authors investigated and recorded 119 plans of houses in Keisho-Hoku-Do area. We can classify the plan based on the relation between Anbang (a living room with Ondol) and Puoku (a kitchen with a fuel hole), existence of Maru, and location of Maru. A diagram of planning patterns was made. It was revealed that Ondol-ban is used for living in winter and Maru is used for living in summer, and the planning patterns are fairly related with climatic regions.
