| Abstract |
buildings usually have a thick plan to maximize their land area usage. This affects daylight contribution in the deeper space of the buildings. Since Surabaya is located at -7.25° S Latitude and 112.75° E Longitude and sky conditions in Surabaya are predominantly in intermediate sky condition (Rahim & Mulyadi, 2000). Those conditions support the use of light pipes where the sun is at around zenith most of the time. The potential of daylight strategy under the circumstance is to bring daylight from the top.
This study demonstrate the potential of using vertical light pipe in Surabaya as one strategy to obtain daylight for deep space building. This research was conducted by model simulation through DIALux 4.13. A room of 16 x 16 x 3 m is created in DIALux using virtual model. Wide space of the room was created to avoid any reflectance effect from wall which falling to the calculation surfaces. The height was set at three meters as this is common in Indonesian buildings. Furthermore, the light tube was set in the middle of the virtual model which has various tube diameters from 0.6 m, 0.8 m and 1 m. Several factors was set to get the actual result such as location of Surabaya, sky conditions, and was calculated on four critical dates. The result proclaimed that vertical light pipe is proper to extend daylight availability since the light pipe provides illumination starting from approximately 40 lux – 250 lux. The final part of this study suggests a method for predicting illuminance by length and diameter of the tube.
