Hyderabad based Skyshade Daylighting Solutions is a company that has come up with several innovative products that capture sunlight and deliver the light in buildings without converting solar energy into electricity.

The increasing emphasis on green technologies has seen several new innovative products now making an entry into the Indian market. One such area which is witnessing interesting developments is “Daylighting”. Light in usable form without ultraviolet radiation, heat or glare is called “daylighting”.

Lighting in buildings has been evolving on the basis of three principles. First, since buildings consume 30% electric energy for lighting, reduction of this consumption with the use of energy efficient lighting technologies should be explored. The T5 and LED lighting has evolved as an offshoot of this idea. Second, use of lighting controls can significantly reduce (up to 25-30%) lighting energy consumption. Thus, proper use of lighting controls can lead to large energy savings. Third, research shows that daylighting has psychological and physiological benefits apart from energy savings. Today, use of daylighting is promoted by forums of green buildings and architecture.

Hyderabad based Skyshade Daylighting Solutions is a company that has come up with several innovative products that capture sunlight and deliver the light in buildings without converting solar energy into electricity.  Skyshade’s solutions work on using the visible light energy (45% of solar energy spectrum) without converting it into power. By removing the ultraviolet radiation, softening the light and reducing the heat, the sunlight becomes usable lighting energy for building spaces during daytime for 9-10 hours. By incorporating special optics technology, the contrast of light variation from morning to peak noon can be reduced. Lighting controls can be incorporated for proportional delivery of electric lighting to compensate reduction of daylight at task plane and thus take care of seasonal variations of sunlight and unexpected variations of sunlight.

Daylighting solutions are very cost effective as compared to solar powered lighting for buildings with payback periods of 2 years or less. Each square meter of a day-lit building can save 16 kWh of electricity annually with a corresponding reduction of 1.385 tons of carbon dioxide emission per year.
