Abstract The architectural window with spectrally selective features and radiative cooling is an effective way to save building energy consumption. However, windows that combine both functions are currently based on micro‐nano photonic structures, which undoubtedly hinder their commercial application due the complexity of manufacture. Herein, a novel tunable visible light transmittance smart (TTRC window) perfect near‐infrared (NIR) shielding ability manufactured via mass‐producible scraping method. TTRC presents high luminous ( T lum = 56.8%), NIR 3.4%), bidirectional transparency adjustment unavailable in other transparent coolers structures (Δ 54.2%), emittance atmospheric (over 94%). Outdoor measurements confirm can reduce 8.2 6.6 °C, respectively, compared ordinary glass indium tin oxide (ITO) glass. Moreover, over 20% annual tropics ITO simple preparation method employed this work superior optical properties have significantly broadened scope advanced commercialization windows.

Abstract Smart windows that can passively regulate incident solar radiation by dynamically modulating optical transmittance have attracted increasing scientific interest due to their potential economic and environmental savings. However, challenges remain in the global adoption of such systems, given extreme variability climatic conditions across different geographical locations. Aiming these issues, a methylcellulose (MC) salt system is synthesized with high tunability for intrinsic (89.3%), which be applied globally various Specifically, MC window exhibits superior heat shielding below transition temperatures, becoming opaque at temperatures above Lower Critical Solution Temperature reducing gain 55%. This attributable particle size change triggered temperature‐induced reversible coil‐to‐globular transition. leads effective refractive index scattering modulation, making them prospective solutions light management an application ahead intelligent fenestration systems.

With the fast economic development and accelerating urbanization, more skyscrapers made entirely of concrete glass are being constructed. To keep a comfortable indoor environment, massive energy for air conditioning or heating appliances is consumed. A huge amount heat (>30%) gained released through windows. Using smart windows with capability to modulate light an effective way reduce building consumption. Thermochromic hydrogel one potential window materials due its excellent thermal response, high radiation-blocking efficiency, cost-effectiveness, biocompatibility, good uniformity. In this work, polyhydroxypropyl acrylate (PHPA) hydrogels controllable lower critical solution temperature (LCST) were prepared by photopolymerization. The transition rate under "static transition" conditions investigated. Unlike "static" in which was not affected initial final heating/cooling ramp, varied change dynamic conditions. "dynamic" PHPA gradually increased increase rate. It result movement molecular chains lagging behind when too fast. results solar irradiation experiment filling into double glazing showed that about 15 °C than ordinary windows, indicating it can significantly consumption conditioning. addition, wide range adjustable temperatures optical response make potentially applicable

Abstract Smart windows offer a sustainable solution for energy‐efficient buildings by adapting to various weather conditions. However, the challenge lies in achieving precise control over specific sunlight bands effectively respond complex changes and individual needs. Herein, novel electrochromic smart window fabricated integrating self‐assembled cellulose nanocrystals (CNCs) layer with an poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonic acid) (PEDOT:PSS) is reported, which exhibits high near‐infrared transmittance, low solar reflectivity (26%), infrared emissivity (20%) winter, (91%), (≈94%) summer. Interestingly, material offers dynamic temperature based on its photothermal properties, maintaining internal of within comfortable range 20–25 °C from morning night, particularly winter significant daily fluctuations. Simulations show that CNC‐PED device demonstrates excellent energy‐saving CO 2 emission reduction capacities across global climate zones. This study presents feasible pathway constructing season‐adaptive windows, making them suitable buildings.
