Overview

This work demonstrates innovative smart windows enhancing energy savings in buildings, suggesting significant performance improvements.

Key Points

  • The goal is to enhance building energy efficiency using dual-responsive smart window technology.
  • Developed a dual-responsive hydrogel combining photochromic and thermochromic features.
  • Integrated hydrogels with solar selective and indium tin oxide films.
  • Designed a tri-band smart window with asymmetric mid-infrared emissivity.
  • Achieved a solar modulation rate of 40.8% and visible light modulation of 61.4%.
  • Demonstrated near-infrared blocking efficiency of 71.7%.
  • Obtained an emissivity contrast of 66% between inner and outer surfaces.
  • Predicted annual energy savings of 14.2%-24.4% for curtain wall buildings.
