Disadvantages of traditional glass curtain wall
[China Glass Network] With the large number of applications and time of the glass curtain wall, many people who work and live in the "glass building" found that although the glass makes the building look light, bright, simple and bright, many disadvantages of the glass curtain wall It is also increasingly prominent.
(1) Energy consumption problem
Since the energy crisis of the 1970s, countries around the world have paid more and more attention to energy conservation. Similarly, the energy issue is currently plaguing China's economic construction and development, and building a conservation-oriented society has become the focus of the whole society. According to statistics, at present, the energy consumption of buildings in major cities such as Beijing and Shanghai has accounted for 1/4 of the total energy consumption of the city, ranking first in energy consumption. The energy consumption of public buildings accounts for the majority of the total energy consumption of buildings. The heat absorption and the heat dissipation in winter also bring a lot of energy to the building while bringing beautiful and beautiful buildings.
(2) Light pollution
The main target of light pollution hazards is still the glass curtain wall of the city's high-rise buildings. A glass curtain wall standing on both sides of the road is like a huge mirror on one side. The light reflection is very easy to induce accidental traffic accidents. If people are exposed to the "white light pollution" of the glass curtain wall for a long time, people will feel deeply depressed and irritable. In addition to the decline in vision caused by long-term reflected light, it will also induce certain diseases. At home and abroad, as glass curtain walls have become popular in the construction of major cities, complaints about light pollution have been rising in recent years.
(3) Security risks
According to relevant experts, many glues used to bond glass curtain wall structures on the market will age or even fail over time. In general, the manufacturer's commitment to silicone and structural adhesives is 10 years. Even in accordance with current technical specifications, the design life of glass curtain walls is no more than 25 years. If the glass curtain wall is in disrepair, it will create many safety hazards and become an "airborne time bomb."
With the implementation of the "Public Building Energy Efficiency Design Standards", the energy consumption and safety hazards of the glass curtain wall have placed it in an embarrassing state, and the news that the glass curtain wall will be stopped or even blocked is endless.
