Solatube Day Lighting Skylight

Vayuvent Day lighting system :- Light tube Day lighting designed on Shade of Industrial to maximize visual comfort and to reduce electrical energy use. Day lighting can be customised for all buildings / Industrial / Factory / Werehouse.

Solatube Daylighting Systems are known as Tubular Daylighting Devices (TDDs). Solatube captures sunlight using a rooftop dome, then transfers the light indoors through a reflective tube that runs from the roof to the ceiling. From there, the light is evenly dispersed into the interior space using a diffuser. While Vayuvents tubular daylighting devices are sometimes referred to as “tubular skylights” “sun pipes” and “light tunnels”. Solatube Daylighting Systems are more advanced and complex than these names imply. They are the only high-performance daylighting device that use patented optical technologies to significantly improve the way daylight is harnessed and delivered to interiors. Unlike traditional skylights, they do not require reframing, dry walling, tunneling, or repainting or days to install. Instead, they can be installed in about two hours with little mess or disruption, and at a fraction of the cost.

Why Day lighting :- Day lighting brings beauty and radiance to your workshop with natural sense of well being and Productivity .

Using day light helps to save energy and keeps resource for the future generation

Payback calculation is worked out in comparison to Electrical Lighting

Energy Savings : Typical 760 mm diameter Day Tube lumen output is 20,000 lumens.
Electrical lighting wattage equivalent to 750mm diameter Day Tube - 475w

Electrical Energy savings per year is
1 Day Tube * 0.475 kw * 10 hrs/day * 365 days * Rs. 7.00/kwh = Rs. 12,136.25

Maintenance cost savings :
Considering bulb replacement & other costs.

Total w * Rs/w = 475 * Rs. 5 = Rs.2375
