**QUANTIFICATION OF THERMAL MASS IN BUILDING IN THE TROPICS**

Kadek Surya Dharma, Ery Djunaedy**Abstract:** The concept of thermal mass is a mechanism to absorb, store and release heat on building materials that aim to reduce peak temperatures and peak cooling loads. Buildings that have good thermal mass must be built with materials that suit with the local climate. Parameters that can represent the thermal mass is the heat capacity, effusivitas thermal, thermal diffusivity, and thermal time. The buildings are constructed with concrete material may simply have better thermal mass when compared to buildings constructed with wood of the same thickness as the concrete has a value greater heat capacity than the timber, but when two buildings constructed with concrete materials of different types, cannot be determined easily which buildings that have a better thermal mass. It is therefore necessary thermal mass calculations and simulations on each type of building to get optimum thermal mass. Optimum thermal mass is the value of thermal mass that has no effect anymore to changes in temperature and cooling loads in buildings. In this study conducted some simple modeling building cubic which consist of various combinations of building type, thickness, material, and geometry, in addition to the simulation and calculation parameters of the thermal mass of each combination of the building to determine the peak temperature of the building, the cooling load peaks and parameters of thermal mass. Furthermore, comparing and analyzing the results of simulation and calculation parameters of the thermal mass of the building all the combinations to get optimum thermal mass to the tropics. **Keywords: **thermal mass, thermal mass parameters, peak cooling load, peak temperature**Paper:**
