HOW GREEN GLASS?
One of the general questions of architects is how glass is a “green” material. “Because our cities are increasingly transformed with the richness of glass in accordance with the standard For carbon emissions and energy efficiency, this means that architects who design glass for their projects need to ensure that glass is designed and used correctly for the purpose of the 21st century.
Legal standards are developed and adjusted based on global warming concerns, availability of materials and prices, and sustainability of materials. Recognizing the problem, the glass industry has more than ever created environmentally-friendly glass products. Combining the benefits of glass with other building materials such as brick, steel, concrete … to solve this problem. The scope of the modern glass industry is that glass is not just for light, but also for other benefits and functions.
For example, in hotter climates, coating or coloration on the glass surface is used to improve the effect of UV radiation and visible light. Reduces the amount of heat from sunlight, keeping the cool inside the building well lit for indoor activities. In cold climates, the glass is coated on the mantle surface to maximize the amount of passive heat entering the building and to prevent heat escaping from the building.
In fact, using the right glasses can help save energy. For typical homes in the UK, the energy efficiency of double-glazed glass is used to save up to 90kg of CO2 per year compared to a single glass. If all single glass in buildings across Europe was replaced by double-glazed glass, we could save 100 million tons of CO2 per year, equivalent to one third of the EU budget for saving. Energy in buildings in 2020.
The possibilities that glass today gives architects are not always the message passed. Architects can now choose glass that can meet almost any desired performance requirement, as well as a number of modern glass technologies that are changing the way buildings are designed.
So the answer to the perennial question is that glass is indeed “green”. You just need to know how to take advantage of it.
