Modeling of vertical light pipes for daylight illumination of indoor industrial buildings

The paper considers a daylight transport system model with light pipes, which provides the illumination of building production areas with natural daylight. The presence of natural light generates considerable physiological effect and affects the energy consumption in a building. The paper discusses correct application of a daylight pipe system based on the use of natural free energy sunlight sources. The advantage of a vertical light pipe application is that the daylight is delivered to the given space. The light pipe system is an effective method of daylight improvement in the existing buildings. The paper presents approaches to illumination modeling using light pipes for achievement of the desired lighting result. Practical examples of modeling for different types of light tubes are given.
