Daylight in buildings based on tubular light guides

Original language description

Tubular light guides (TLGs) represent a solution for energy efficient performance of light during a day based on the daylight transport into building interiors. While daylight from windows sufficiently illuminates rooms close to building envelopes the light guides improve visual environment and perception of architectural space in deeper parts of interiors. The main aim of this study is focussed on the evaluation of efficiency of two selected TLG systems experimentally tested in temperate climatic conditions. Firstly, daylight illuminance measurements under the light guide installations were performed for one year period with documentation of the typical daily illuminance courses. The measurement results show differences between daylight efficiency of these systems. Secondly, spectral reflectance of the light guide tubes was measured and analysed to find out material influence on light transport effectiveness. Finally, daylight simulations were carried out applying software HOLIGILM for determination of daylight illuminance under the TLG of various dimensions. The study gives general overview about potentials of daylighting applications for straight light pipe systems.
