N2 - This study aims to evaluate the novel “TABS ceiling slits”, designed to achieve daylight harvesting and solar heat removal, based on their cooling effect and the indoor thermal environment through heat balance simulations. The heat balance model was validated with field measurements conducted summer 2020, and two analyses were conducted. In the first analysis, the effects of supply water conditions on the heat extraction of the TABS ceiling slits and the operative temperatures of the office space were verified. In the second analysis, the comprehensive design conditions of the TABS ceiling slits were investigated through a parametric analysis with the embedded pipe location as an additional parameter. The results showed that the solar radiation removal performance and the indoor thermal environment could be sufficiently satisfied by the water supply conditions and the pipe locations in the actual design.
