Window to the Future
The technology can adjust the amount of sunlight coming into buildings in the day, which promises energy savings from the outset and over the long term
In 2014, NTU scientists developed a ‘smart’ window that could act as a rechargeable battery, and brighten or darken a space without external power source. The first in energy use, the self-powered window contains liquid electrolyte between two glass sheets. Electricity is conducted when ions pass through the the liquid electrolyte from one glass sheet to another. On the market, windows that can be dimmed and brightened have to be powered by an external energy source. These ‘smart’ windows are estimated to be 44 per cent more efficient than windows that cannot filter the amount of light entering a space.
- Saves energy; reduces amount of heat entering building thus keeping environment cool without air conditioner
- Facilitates efficient energy use
- Low production cost
“Our technology is very attractive as a zero-sum consumption smart window. Building owners and even common households can reap energy savings right from the outset and over the long term.”
Prof Sun Xiaowei
With the commercialisation of the smart window, more households across Singapore can take advantage of the cost-savings, particularly among the low-income. In the long run, Singapore can help play a significant role in fighting global warming. By contributing, you support the global energy conservation cause, and facilitate large-scale savings on energy across the nation.
