Generally, Malaysia is located in a hot and humid zone. Conventional ventilation systems with mechanical ventilation are used to obtain cool indoor air temperature. However, in special areas such as microscope transmission labs and hospitals, static airflow cooling is difficult to apply due to the large space required. Radiant cooling systems are therefore adapted to replace modern air-conditioning systems. The systems typically utilize a hydraulic system, which is to cool the air by circulating cold water in the pipes through floor, ceiling and wall. When the surface temperature of the radiation is cooler than the ambient temperature, the heat from that environment is absorbed into the water stream and indirectly cools the space. In this situation, the basic concept of heat transfer is applied where the heat moves from hot surface to cold surface. In this study, three stages of the methodology will be conducted. The first stage is to design a building prototype. Later from this design, a fabrication process will be carried out to complete the prototype building according to the specifications given. The final stage involves experimental work, in which all the measurements needed will be taken. Thus, the water temperature at the inlet flow and the wall surface temperature are recorded. As the temperature of the inlet water decreases, the surface temperature decreases as well as cooling load requirements has been achieved. Temperature differences at the end of the study indicate that cooling in that specific area has taken place.
