This paper focuses on verification of impacts of practical renovations regarding thermal performances, which can be applied conventional wooden frame houses in mild climate regions. The practical renovations in this paper consist of followings; 1) Install insulation materials to the ceiling and the floor, 2) Insert wrapped batt insulations to prevent exfiltration at the connections of the wall and the floor, 3) Exchange single glasses for double glassings on windows. These methods were demonstrated on an actual wood frame house that satisfied the former energy conservation standard. Impacts of the renovations on air tightness and specific heat loss coefficient were clarified quantitatively by nonlinear regressions and field measurements. Furthermore improvement of indoor environments and hygrothermal behavior after the renovation were studied.
