Skylights are light-transmitting envelopes buildings which form all, or a portion of the building space most especially the roof top. Skylighting types include roof windows, unit skylights, custom skylights, and the tubular daylighting devices.
- To allow sunlight, either direct or indirect (daylighting elements).
- It gives a kind of visual connection between the outside or environment and the occupants in the house or building as the case may be.
- It provides passive solar heating and with units; for ventilation (passive cooling) and exchange of fresh air.
A retractable skylight is one off the frame, and the interior of the facility is entirely open to the outside. This can be called a retractable roof which implies a very high degree of transparency.
Active daylighting is a unit of skylight element which distributes light by diffusion. It is used in spaces tiny like hallways where the light can bounce into the dark corner spaces. They illuminate sidewalks, open areas, and well lit interior floors. They are used in the architectural world widely for designs of residences, public and commercial buildings. Daylighting of course, when increased, could lead to a less electrical lighting use and a little dependence on side lighting, which is via the window. It also saves energy, lowers cost and reduces the environmental impact that could be hazardous to human lives in commercial buildings and properties. Daylighting is used to cut out light energy used in some buildings even up to 80%. Skylight works well with windows to effectively supply light to the room. It does this by:
- Bringing light to the centre of a building.
- Light is made available throughout the day from both lightings from the sky and direct exposure from the sun.
- Transparent or translucent glazing is used to avoid glares and also helps to capture sunlight even from low angles and spread light to wider areas of floor space.
Skylight gives top lighting which is far greater and more efficient than side lighting.
Did you know, that a study shows that students have significantly higher test scores in classrooms that provide enough daylighting than classrooms that do not?
Other studies show that light from the day, positively influence the physiological and psychological well-being that is, it can increase productivity even in many areas such as sales and retail spaces. It also saves costs, in that any commercial building can reduce the total energy costs they would have used on a normal day by one-third through the effective and optimal use of daylighting or skylighting as the case may be. Most halls, companies (reception areas), and other commercial warehouses and huge stores that have been constructed in recent years have extensively depended on skylight as their source of illumination which has helped them in energy savings or cost savings. Skylighting also adds a form of beauty depending on the kind of material by which it is made to areas used. It is best used in libraries.
Resstende offers a wide range of skylights for conservatories, winter gardens and the screening of any other slanted or horizontal glass areas. The skylights with a double cover box have been designed for indoor installation on medium sized horizontal or slanted windows, however they may also be used on vertical windows where, for example, the blind is required to open from the ground upwards. Other skylights systems include: the Wintermeeting for vertical, slanted, horizontal or curved surfaces; the Orizzonti blind designed to cover large horizontal areas, particularly indicated for outdoor installations.
