How about a glass building with a low strength glass?

China Building MaterialsGlassSince the invention of architecture, it has been plagued by several problems. First, the quality of the glass is not reliable, the intensity is not high enough. And broken glass will produce sharp debris, easy to cause damage; followed by the greenhouse effect of the glass, will be shot in the infrared energy to retain, in the summer is very hot, not suitable for living. Finally, in the indoor and outdoor temperature difference is bigger, the glass surface is easy to have water vapor condensation, affect the transparency.

China Building Materials

These problems have not been solved for a long time. Until the last few decades have a better solution. First, the tempering". After tempering(heat treatment)The glass impact strength is 3~5 times higher than ordinary glass, and even fragmentation into small pieces of glass is broken free of sharp. Two is hollow". holdCurtain glassDouble layer (or even three), between the two pieces of glass filled with dry air or inert gas layer, can greatly improve the insulation, heat insulation, sound insulation performance. According to the measurement, when the outdoor temperature is -10 DEG C, monolayer glasswindowBefore the temperature of -2 DEG C, and the use of three layersHollow glassThe indoor temperature is 13. It should be emphasized that the air filled with insulating glass must be dry, which is to prevent the condensation of water vapor in the winter in the inner layer, the impact of transparency. Three is "double silver". The glass is plated silver thin film two, this "double silver glass" can work well through visible light, it can make the sun's heat (infrared) reflected. In the hot summer, the double layer double silver insulating glass can block 90% of the solar radiation heat through the 90% visible light.
The improved glass curtain wall, jazz, popular, and "unlimited scenery". From the outside, edifice like wearing beautiful glass coat; into the building, light transparent, everywhere is the "big screen" unlimited panoramic scenery out of the window. The daytime indoor bright, greatly reducing the artificial lighting; at night, the glass curtain wall building became transparent.“crystalThe Palace”,又There is something elselampThe charming landscape fire lit not nocturnal city.
Because of the superiority of the glass curtain wall in the architectural design, it quickly swept the world. New York, Tokyo, Ginza, Hongkong, Tongluowan, Shanghai, Pudong, has become a glass curtain wall buildings gathered in the place of. The glass curtain wall in 1984 before entering the China, but in a short period of more than and 30 years, Chinese has emerged as the world's largest "glass power": glass curtain wall area soared to 200 million square meters, accounting for 85% of the world; Chinese curtain wall glass production accounted for 75% of the world. In Shanghai alone, there are more than 3 thousand buildings in a gorgeous glass curtain wall.
However, the glass curtain wall also has disadvantages: one is the glass although the quality has been greatly improved, but does not completely eliminate the explosive phenomenon, in order to avoid the "glass rain drop from the clouds and pedestrians around the glass curtain wall building usually need to set up a green belt; the second is the reflection intensity of glass curtain wall is about 10 times that of ordinary decorative materials. The" light pollution ", will cause harm to human health. Therefore, residential buildings, school buildings shall not use glass curtain wall.
