摘要
Architecture and the building industry consist of several minor fields, which come together when a building is designed and erected. One of them is the field of building physics. It primarily focuses on the evaluation of constructions, structures and spaces with respect to thermo-technical conditions, daylighting and many more. It is believed that among the above-mentioned sub-fields of building physics, daylighting is the most important because it influences the health of every human being. Daylighting enables people to see the colours and objects surrounding them. Therefore, buildings have to be equipped with a kind of daylighting system. In the past, spaces located either in the centres of buildings or in the underground areas were illuminated solely on the basis of luminaries. Nowadays, indirect daylighting systems like optical fibres or tubular light guides may also be utilized. In Central Europe, the application of tubular light guides in buildings increases every year. The manufacturers say that this is an important and maintenance-free system. It is a system that brings light into any building, thus helping to save money. On the other hand, the designing of tubular light guides is complicated as it has to deal with daylighting, thermo-technical aspects and moisture. A huge amount of light guides is problematic due to the condensation of water inside the pipes, which is a side effect of a non-air-tight solution, or just due to an incorrect thermal analysis. The paper focuses on different aspects of designing light-guiding systems through computer simulations.
