Using nanocrystals to coat windows for energy efficiency

This is Science Today. Tiny crystals of inorganic materials called nanocrystals are being used for various energy applications by researchers at the Lawrence Berkeley National Laboratory. Staff scientist Delia Milliron says in particular, they're interested in how to use nanocrystals as coatings on windows to improve the energy efficiency of buildings.

Milliron:         The most benefit for energy efficiency with our coatings would probably come from homes because that's where you can take most advantage of the solar heat gain coming from the sun.

Narrator:        The Lab has a windows test facility where researchers can install full-size prototypes of new types of windows containing all different coatings on the market.

Milliron:         A big issue for new window coating technologies is to make sure that the cost is low enough that it's available to all the people that might want to buy it and improve the efficiency of their buildings. So, we're really excited about our technology using a solution-based process because it has the potential to really bring the cost down to the point where it can be deployed broadly in the market.
