Fig. 4: Scalability and thermal shielding performance of the OECD.

a Photographs of a 20 × 20 cm2 OECD fabricated via blade coating. b A flexible 10 × 10 cm2 device under mechanical bending. c Dynamic transmittance at 550 nm measured at the center and edge of the device during a full switching cycle (from − 2 V to 2 V). d Solar irradiance spectra derived from the measured transmittance spectra at different bias voltages. e Indoor temperature setpoints used in EnergyPlus simulations to replicate real-world climate control scenarios. f Simulated annual cooling energy savings for an office building in Guangzhou using the OECD at different operational states, benchmarked against commercial low-E glazing. g Global simulation results showing absolute (MJ m⁻2) and relative (%) reductions in annual cooling energy consumption when replacing low-E glass with the OECD ( − 2 V), across diverse climate zones.
