Light air pollution of glass curtain wall

The gentle pollution of the glass curtain wall refers to the use of  coated glass on the curtain wall of large-increase properties. When immediate daylight and skylight are irradiated onto the glass surface, the specular reflection (ie, specular reflection) of the glass. And the ensuing reflected glare.


Light pollution is the murderer of accidental visitors mishaps. A glass walled building stands like a large mirror with a width of tens of meters and a top of almost one hundred meters. It demonstrates the site visitors circumstances and traffic lights (even multiple reflections). The mirrored gentle enters the auto at large velocity, which will lead to sudden temporary blindness and visual illusion, which will protect the driver’s eyesight in an instant, or make him feel dizzy and critically endanger the visible operate of pedestrians and motorists. The glass curtain partitions developed around the residential location will reflect the bordering properties. According to optical specialists, the reflected gentle of mirrored developing glass is more powerful than that of daylight, and its reflectivity is as high as 82% to ninety%. The mild is almost fully reflected, which greatly exceeds the range that the human entire body can bear. In the summertime, the sun is mirrored into the dwelling space. The powerful glare is the most damaging to the original very good atmosphere in the place. It also raises the place temperature by an average of four °C to 6 °C. Folks who work and stay in a white brilliant and polluted environment for a prolonged time might very easily lead to diminished eyesight, dizziness, insomnia, palpitations, decline of appetite and despair, and other signs and symptoms of neurasthenia, which may possibly cause alterations in typical physiological and psychological problems. Long-phrase will induce specified illnesses. Consequently, the Condition Environmental Defense Administration has gained issues about mild pollution all in excess of the place every single year, which has captivated the focus of appropriate state departments.
Gentle pollution is created below the following certain conditions: (1) the use of large areas of high reflectivity coated glass (2) in a distinct route and at a certain time (3) the degree of light pollution and the path, place and top of the glass curtain wall Have a close partnership. Because the human’s angle of view has the biggest impact inside an angle of ±15 degrees around 2 meters, the intensity of mild reflection is inversely proportional to the square of the distance from the reflector to the human eye.
In current years, governments and related academic groups have attached fantastic value to the concern of light-weight pollution, and have successively revealed a collection of technological documents, specifications and decrees to control light-weight air pollution. China has also hooked up great importance to the problem of curtain wall design. In 1996, the restrictions on the technological specifications of curtain wall engineering and the provisional regulations on strengthening the management of developing curtain wall initiatives have been successively released, which manufactured the good quality of manage curtain wall initiatives have a legal basis. In accordance to their true scenario, various localities have also taken some corresponding possible measures.

greenhouse glass of the dilemma of light-weight pollution does not suggest that the glass curtain wall need to not be accomplished, but how to do it nicely. At current, the development of substantial-tech has designed the materials of curtain wall from one glass to steel plate, aluminum plate, alloy plate, marble plate, enamel sintered plate, and many others. By way of reasonable layout, the glass curtain wall and the curtain wall of metal, aluminum, alloy and other components are merged. Together, it not only can make the substantial-increase structures a lot more gorgeous, but also lowers the light pollution triggered by the reflection of the curtain wall far more effectively. It can more reduce the self-weight of the large-rise properties and give total enjoy to the advantages of the curtain wall creating materials.

Glass plays a important role in the glass curtain wall. The glass type of the glass curtain wall ought to be cautiously selected according to some parameters of the glass, and the glass with glare reduction efficiency should be picked. These parameters contain the gentle and weather parameters of the developing internet site, the transmission variety of seen light, Reflection coefficient, transmission coefficient, reflection coefficient and absorption coefficient for sunlight, as nicely as warmth transmission coefficient, thermal expansion coefficient, and thickness, maximum size, bodyweight, and wind resistance. It is nicely known that glass has transmission, absorption and reflection properties for light. The glass curtain wall utilizes diverse sorts of glass in accordance to these attributes. The glass employed for the glass curtain wall generally has clear glass, coloured glass, heat absorbing glass, coated glass, coated glass, laminated glass, and photochemical glass. The advantages and down sides of every single of them can be noticed in the glass used on these glass walls.
