【 摘 要 】
This paper presents the results of a preliminary experiment using test cells constructed in Bandung, Indonesia. We particularly analysed the thermal effects by comparing green walls with wooden blinds in contrast with those of no covering materials to determine the factors affecting the improvements of indoor thermal conditions in hot-humid climates. The results showed that, unexpectedly, indoor thermal conditions were not improved when green walls/blinds were installed, at least at the center of the units. Nevertheless, air temperatures behind the green walls were found to be lower than those of the other conditions. Moreover, the factors affecting the Standard Effective Temperature (SET∗) were analysed in detail by dividing SET∗ into four thermal factors in terms of temperature, including air temperature, radiation, humidity and wind speed. The further analysis showed that the increases in SET∗ in the units with green walls were mainly attributed to the reduction of wind velocities (36-45%). It can be concluded that the airflow blockage effect by the green walls was larger than its transpiration cooling effect at the center of the units.
