| Solatube Daylighting System ![]() The challenge for designers and engineers is that the potential weight of all of this earth and water means that the roof structure has to be bolstered to cope with the increased stresses. Bringing daylight through such structures presents a new list of problems through these deep roofs. A traditional skylight delivers an amount of light which corresponds directly with the size of its aperture – the bigger the aperture, the more light there will be. But bigger apertures also weaken the roof structure. The trick is to get maximum light through small apertures, and this is where tubular daylighting devices can really be used to great effect. For example, a 530mm diameter Solatube Daylighting System will light an area of up to 32m2, with an aperture that can be easily accommodated without affecting the structural integrity of the roof. And because the Solatube Daylighting System uses reflective tubing to bring the daylight into the building, it can be positioned above the roof level allowing for the green medium to grow without blocking out the light entering the tube. The light can then be piped deep into the heart of the building, greatly reducing the reliance on electric lighting and boosting the building's environmental credentials. write your comments about the article :: © 2009 Construction News :: home page |
