Windows and Envelope Materials

The Windows and Envelope Materials Group develops energy-efficient window systems, and studies advanced daylighting designs, which allow the use of natural light in place of electric lighting.  It also works to cool buildings, cities, and the planet with solar reflective roofs, pavements, and cars.

Key topics:

  • advanced materials, coatings and deposition technologies  for windows
  • energy performance of window systems, including windows, glazings, frames, and blinds
  • computer tools to improve energy performance and aid product rating and labeling
  • daylighting strategies, including sensors that detect light levels and occupancy, and adjust electric lighting appropriately in response
  • cool roofs and cool pavements
