Abstract
Abstract TABS (Thermally Activated Building System) has recently applied by huge commercial buildings, airports, and convention centers in Europe. TABS provides night-time thermal storage by heating or cooling. The embedded water-basedheating and cooling system uses the high thermal inertia of concrete in the building construction, in which a heating orcooling pipe is embedded. The aim of this study is to analyze the thermal storage and thermal output of TABS applied with PCM (Phase Change Material). To achieve this, prototypes of TABS and the thermal properties of various PCMs wereinvestigated. By using the simulation program Physibel Voltra 6.0 W, the thermal storage and thermal output were evaluatedaccording to a heating and cooling operation schedule.
