Use of commercial skylights in schools, hospitals, offices and industrial places after being studied by technical experts, is reported to have positive and significant impact on the performance of people correlated to their work. According to the experts, natural light boosts the energy up to 24 percent in any person, which increases activeness and hence their productivity. It decreases the absenteeism of employees, indicating that they like the working environment lit by natural light.

People use various types of skylights to get sunlight into a commercial space, like venting and fixed skylight windows on the roof. The most economical of all these skylights are the tubular skylights, which efficiently, light up the workplace and add to its beauty. Architects use this type of skylights on flat or sloped roofs. Tubular skylights are designed to integrate easily with a suspended ceiling. They are made of rigid tube, which have a highly reflective inner surface. The tubular skylights have a special telescopic design that helps to carry the sunlight to greater lengths and to areas not under direct access by using bends, thus minimizing any loss of light. They effectively distribute the sunlight by letting it pass through a prismatic diffuser.

The commercial tubular skylights are available in various sizes. Generally, tubes of 21-inch size are used for larger workplaces, and one such tubular skylight would light up an area of 600 square feet, delivering up to 1,400 watts of light. The commercial tubular skylights are leak proof and can withstand strong winds. It has a UV protection feature and a condensation system, to keep the moisture out of the place. Quality aluminum flashing is used to fit the tubular skylight on any type of roof.

Daylighting experts can help to find out the number of skylights that would be required to attain the maximum benefit by saving energy and to achieve the necessary level of lighting. Proper design and implementation of commercial tubular skylights help us switch off the artificial lighting on an average of 70% to 80% of the time. The use of these healthy, energy saving skylights is common in green friendly office and commercial buildings.
