Energy Saving Glass Coating


Recently, a group of international researchers led by scientists from Nanyang Technological University in Singapore developed a glass window coating that can effectively self-adapt to heat or cool rooms in different climate zones around the world, helping to lower overall energy consumption. This first of its kind glass coating, capable of regulating heating and cooling at same time, is developed by forming a unique structure that consists of layers of vanadium dioxide nanoparticles composite, Poly (methyl methacrylate; PMMA), and low-emissivity coating. Without any electrical components, the glass functions by exploiting the spectrums of light responsible for heating and cooling.

The team of researchers found that the newly developed glass was able to achieve energy savings of up to 9.5% in both warm and cool seasons as compared to commercially available low emissivity glass. Currently, the modulations of radiative cooling have not been studied in conventional smart windows. As such, this development highlights the potential for implementation in sustainable buildings globally.
