TI-wall is an Mass-wall with TIM used instead of an usual single, double and triple glassed windows. The aim of this study is to analyze the thermal performance through Test-Cell of TI-wall in domestic climate. This study is carried out as follows: 1) Test-cells of TI-wall and Mass-wall are designed through the investigation of previous paper and work. The type of the TIM used in test-cell is small-celled(diameter 4mm and thickness 50mm) capillary and cement brick(density 1500kg/m3) is used by thermal mass. 2) individual and combination test with various variants, such as thickness(190mm, 380mm) and surface absorption(60%, 95%) of thermal mass wall, measured for winter and spring, and the thermal effects are analyzed. Finally, as results indicated that the peak point time of the temperature of in-and-out surface is cut down approximately by an hour when the surface absorption of thermal mass wall is changed from 60% to 95% In case of applying for 1B(190mm) in thickness of thermal mass wall. In case of applying for 2B(380mm) in thickness of thermal mass wall, the temperature difference between in-and-out surface is showed about 23℃ in terms of Spring and Autumn. It means that the heat could not be delivered enough because the distance for heat transmission is too far. Therefore, in case of more than being 2B in thickness of thermal mass wall, it is not right for heating in Winter, Spring and Autumn. Experiment in term of summer, the thermal mass wall is heated enough by outside temperature and solar radiation, the temperature difference between in-and-out surface is indicated 10℃. Also, inside temperature is sustained more than average 28C. Therefore, radical temperature rising will be released by changing its thickness, but the inside temperature still remains in high.
