A self‐regulating liquid crystal (LC) smart window whose reflectance can be controlled by ambient conditions is demonstrated. Thermally‐ or optically‐induced switching between the transparent state and a near‐infrared (NIR) reflective state can be used for energy‐saving windows. Reflection of NIR can reduce the energy used for cooling while remaining transparent to visible light.
