Windows and Envelope Materials

Windows and Envelope Materials

Windows and Envelope Materials researchers develop energy-efficient window systems, and studies advanced daylighting designs, which allow the use of natural light in place of electric lighting. Its research areas include:

  • advanced materials and coatings for windows
  • energy performance of window systems (such as 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-colored roofing materials to reduce urban heat islands and air conditioning energy use
