NUMERICAL SIMULATION AND EXPERIMENTAL STUDIES ON RESIDENTIAL HOME USING EVAPORATIVE COOLING AND VERTICAL VENTILATION

The limitation of land in urban area leads to the existence of land slowly omitted and changed to be functioned room. The additional room itself will be reducing thermal comfort in the house. To maintain thermal comfort, some alternative solutions are directed in conjunction with modern technologies, for instance using air conditioning system. However, the solution proved that it can produce more energy extravagance, and stimulate global warming (Givoni, 1998). Therefore, alternative natural cooling system with less energy consumption for getting comfortable level in residential house and similar building is required. The work described here is a computational fluids dynamics (CFD)study aimed at validating the numerical method with experimental data available from a house incorporated with vertical ventilation system which existed at Surakarta Indonesia (Azizah R. and Qomarun, 2014). A detailed computational model of the house device has been established
