Glass curtain wall industry suggested regulatory

Since the advent of the glass curtain wall building, with its light weight, short and stylish features, favored by many builders. Since 1984 in Shanghai China's first glass curtain wall building---friendship building to fall, in more than 20 years, China's rapid development into the world's first production of glass curtain wall and use power. But with the application of the broad security problem caused glass curtain walls are more and more attention.
Beautiful huge hidden under the cloak of
It is reported that China now has 200 million square meters of glass curtain wall, accounting for 85% of the world, has become China's urban fashion label, however, confusion, absolved of responsibility, resulting in each piece of glass curtain wall glass could be a safety hazard, every passerby might get hurt. In constant pursuit of speed and a high level of urbanization in China train, glass curtain wall of the glamorous "modern dress", is once again on the other side of exposing ferocious.
From early July 19 Qingchun East Road girls innocent Zhu started the tragic amputation, glass from the explosion also occur: Hangzhou gate style glass door blew away from the center of the street and wounding three girls; Ningbo globe, 21/f, glass curtain wall burst, it began to "glass rain" ... ... Since the summer, the province total glass from blast events took place more than 10. Glass curtain wall building supervision and management to ensure urban security, became public to look forward to in the summer.

Caused by light pollution of glass curtain wall
In addition to safety concerns, a large area of glass brings serious "light pollution". Research showed that, mirror glass of light reflection coefficient can reached 82%-88%, this let we in senior building in the big area using of glass curtain wall, far see to on like a chunks dozens of meters wide, and near hundred meters high of huge mirror, and on traffic situation and traffic lights for reflection, dang reflection light into high-speed driving of car within, will caused people of burst sex temporarily blind and vision illusion, serious to against pedestrian and driver of Visual function.

National housing sector in 2006, the existing safety measures for the maintenance and management of building curtain wall, owner of clear glass curtain wall "in principle" once every 10 wall security identification is required, and guarantees for routine maintenance, repair, security, identification and overhauling fees.

So, is there any similar institution in Hangzhou? When we encounter a glass off, self and other security issues, in addition to the accountability of property units, who supervises the else can? And which institutions in the glass before self, find will nip the danger in the bud?
