Overview

Randomized trial demonstrates reduced energy consumption in smart windows, highlighting energy efficiency advances.

Key Points

  • The aim is to develop a dual-responsive smart window that significantly enhances energy efficiency through optical modulation.
  • Designed a dual-responsive electro-thermochromic smart window using Prussian blue electrodes and hydroxyl cellulose-based hydrogel electrolyte.
  • Evaluated optical modulation, ionic conductivity, and switching kinetics of the smart window under varying conditions.
  • Operated the window in four distinct modes to assess energy-saving potential.
  • Achieved 87.3% visible-light transmittance modulation and 50.5% solar modulation capability.
  • Demonstrated potential annual energy savings of 129 MJ m−2, with reductions of 35%–55% in energy consumption.
  • Showed high coloration efficiency at 108.21 cm²/C and fast switching times of 5 seconds for coloring and 6.8 seconds for bleaching.
