摘要

It is known that the electricity consumption of buildings is increased for lighting as well as comfort around the world. Efforts should be made to reduce such consumption as much as possible. Artificial lighting must be used as a supplement to daylighting. Daylighting is increasingly being used for commercial as well as residential multistoried buildings, where people work during daytime. The technology of solar energy collection and transfer to room is under study nowadays. For collecting and concentrating solar energy the ideal cylindrical light collector has been invented, which is known as CPC (Compound Parabolic Concentrator). It is capable of accepting solar radiation over an average eight hours a day and concentrating it by a factor of about ten without diurnal tracking of the sun. The CPC has a larger acceptance for diffuse light than any other collector. This characteristic can be used for illumination of the rooms by integrating it with light duct, without increasing much cooling load. Here, the authors try to analyze the performance of CPC integrated light duct solar daylighting system for illumination capacity with respect to location of Ahmedabad (23.04°N).
