主　　题：Daylight Light pipe two aperture Densely populated urban kampung Housing Hot-humid climates 

摘      要：Daylight is one of the essential criteria for decent ***,in an urban kampung,access to daylight is limited due to the high-density population in urban Kampung *** study aims to improve the visual and thermal conditions by modifying the aperture of the light pipe based on visual daylight distribution,illuminance level,and thermal conditions in multi-storey houses in hot-humid *** pipe was developed experi-mentally through the simulation model to investigate the performance and impact on the visual and thermal conditions like operational temperature and RH in densely populated Kampung Kota without vertical *** to the results,the two-aperture light pipe residential space enhanced the current situation but did not fulfill the *** two aperture light pipe visually improved daylight distribution by 1.05%-31.36%and illumination level by 8.4%-14.8%.We also found that light pipe also impacts thermal conditions with a 10.92%RH reduction while at the same time increasing temperature up to 10.57%.Therefore,it can be concluded that a two-aperture light pipe has the potential to be applied to actual conditions in hot-humid climates.
