A global performance analysis with weather conditions from 20 cities is conducted on a solar-driven indoor air carbon capture model to uncover the influence of solar irradiance and ambient temperature on the novel systemâ€™s carbon capture performance and cooling energy-saving performance. Results show that solar irradiance significantly affects collected CO2 mass while temperature affects energy-saving amounts. Specifically, for a 40 m^2Ã—2.8 m room with 39 occupants, the proposed system can capture 37.2-41.03 kg CO2 per day and achieves an energy-saving performance between 23.95%-50.66% in different cities. This study sheds light on effectively and renewably capturing CO2 from indoor air worldwide.
