This study was examined to grasp the influence of void-space with stairway on indoor thermal environment and to propose the measures to reduce cold-draft using full-scale test house. The results of 1st tests showed that cold-draft occurred near stairway at void-space in the living room, even on floor heating area, that cold-draft was reduced when running heating on the 2nd floor. We proposed and tested the measures to reduce cold-draft. The results of 2nd tests showed that cold-draft nearby FL+100mm level was reduced by the measures beside down-stairs, but that air velocity and temperature in occupied zone above FL+100mm were not improved as indoor air-flow patterns were changed.
