N2 - Air-conditioning systems account for nearly one-third of the energy consumption in tropical buildings. In summer, mechanical cooling systems become a must especially in office buildings to keep the indoor environment comfort. In this study, a normal office room is designed to evaluate a novel cooling system based on a hot and humid climate. This novel cooling system is considered to serve such climate, which integrates radiant cooling panel, decentralized ventilation, and an Airbox convector. The Airbox convector is designed to deal with condensation risk and provide additional cooling output. In order to evaluate this novel system, it is compared with conventional all-air system and normal radiant system with decentralized ventilation regarding to the system capacity, energy consumption and thermal comfort. Results show that this novel system is adaptable to such climates and capable to reduce the condensation risk and overall cooling energy consumption.
