• • The ZIRM hybrid film achieves solar reflectance of ~95% and thermal emissivity of ~0.88 in the RC layer, while the absorption layer attains solar absorption of ~93% and thermal emissivity of ~0.37, enabling dual-mode radiative control with high spectral selectivity.
• • Programmable RC/RH area ratio modulation yields a daytime temperature differential range from −4.3°C (cooling) to +12.1°C (heating), demonstrating broad climate adaptability for building envelopes.
• • Annual energy consumption of ZIRM is 1.45×10^10 GJ, representing a 9.9% reduction compared to pure radiative cooling and a 2.7% reduction versus pure radiative heating systems, substantiating its energy-saving potential.
• • The 'configuration-environment-performance' predictive model integrates material design with climate-specific optimization, offering a scalable framework for carbon-neutral building retrofits.
