Conventional smart windows only regulate solar transmission. For the first time, we developed high thermal energy storage thermoresponsive smart window (HTEST smart window) by trapping the hydrogel-derived liquid within glasses. The excellent thermoresponsive optical property (90% of luminous transmittance and 68.1% solar modulation) together with outstanding specific heat capacity of liquid gives the HTEST smart window excellent energy conservation performance. Simulations suggested that HTEST window can cut off 44.6% heating, ventilation, and air-conditioning (HVAC) energy consumption compared with the normal glass in Singapore. In outdoor demonstrations, the HTEST smart window showed promising energy-saving performance in summer daytime. Compared with conventional energy-saving glasses, which need expensive equipment, the thermo-responsive liquidtrapped structure offers a disruptive strategy of easy fabrication, good uniformity, and scalability, together with soundproof functionality that opens an avenue for energy-saving buildings and greenhouses.||URI:||https://hdl.handle.net/10356/146998||ISSN:||2542-4351||DOI:||10.1016/j.joule.2020.09.001||Rights:||© 2020 Elsevier Inc.
