Design Strategies of Light Pipe-An Innovation for Energy Sustainability

The significance of applying the natural daylight in indoor spaces has been increasing day by day. The haphazard growth of cities, demand of increased population density in small localities made the people to utilize the artificial energy sources even throughout the day time for effective lighting. The increased burden on fossil fuels for energy made people to look for other alternative energy methods. The renewable energy has shown a relief to some extent in the form of solar, wind, geothermal, tides, biomass and so forth. The present paper highlights the effective energy enhancement of solar energy in the form of light pipe. It describes the models of light pipes which are most popular in the world. It also describes the design aspects and advantages of light pipes over the conventional mode of energy.
