Abstract
  • The walls of Corridors are usually opaque resulting in very dark conditions relying solely on artificial lighting. This paper aims to investigate the extent of daylight which can be borrowed to light the internal enclosed corridors. This is carried out by experimenting on the various types of corridor wall designs with added transparent or glazed areas for daylight to be borrowed to the enclosed corridors. The designs experimented with various horizontal and vertical alternatives. The effects of these new corridor wall design to daylight distribution in corridors are investigated by Radiance simulations. Results are compared to the base case which is a situation of all opaque walls for the corridors as the worst situation. The findings show that the newer designs of corridor walls can provide daylight to corridors with significant improvements. Even though the %DF found were very low, outdoor illuminance in tropics is high therefore it is still sufficient for corridor lighting. Corridors with 50% glazed areas in a 4 strips horizontal design were found to perform the best for allowing borrowed daylight to occur.
