Abstract
In present scenario, many countries in the world are facing huge power crisis for domestic and industry needs. Fossil fuels are no longer going to support the present demand and renewable energy is the only alternative to meet the crisis. Solar energy has highest potential for utilization as alternative energy source. This paper reviews the current daylighting strategies incorporated to a building. The development of a highly efficient reflective and refractive materials have made the redirection of daylighting into areas of buildings far away from the façade. Cities are consuming more power in day time as cities set backs are not maintained properly for buildings as per municipal norms . To address these problems, an innovative sustainable technology named as Light Pipe is proposed and explained in order to resolve these issues very effectively and economically for better building lighting services. Light pipe system is one invention that transports daylight efficiently from outdoor into rear part of a room. It does not only provide sufficient luminance into the room but also improve the internal environment without generating excessive heat.
