Problem addressed

E-COATING is an innovative, eco-friendly solution created from recycled glass. It can be applied to the exterior roofs and walls to reduce heat absorption of buildings, which in turn reduces the amount of electricity consumed on cooling and associated greenhouse gas emissions.

Innovation
  • E-COATING is a cooling coating made from recycled glass.
  • E-COATING lowers a building's cooling load through solar reflection and thermal emission which do not require electricity by reflected most of the sunlight.
Key impact
  • Utilize low-cost radiant cooling technology to provide society with high quality, environmental friendly and cost-effective coating solution.
  • Reduce the electricty consumption of buildings and help society move towards carbon neutrality.
  • Reduce the amount of solid waste in landfills by researching and implementing innovative recycling solutions.
