Radiative Cooling Improvement by Retro-Reflective Materials

Published: Jan. 1, 2025

Cool materials are essential for reducing energy demand in buildings, particularly cooling-dominated zones (CDZs), and mitigating the Urban Heat Island (UHI) effect. Their effectiveness relies on two primary physical properties: their ability to reflect solar capacity emit infrared radiation, both of which especially beneficial horizontal surfaces like roofs pavements. However, vertical surfaces, such as façades, also play a significant role urban thermal balance. Conventional often underperform these due non-directional properties. This study investigates Retro-Reflective (RR) materials, exhibit directional emissivity reflectivity, enhancing performance surfaces. To assess potential RR an original measurement campaign was conducted, where several kinds were realized by varying size density embedded glass beads. It observed that properties, along with concentration factor global can be effectively tailored through proper manufacturing match specific working conditions, surface temperature, incident angle, canopy geometry. An important improvement respect diffusive one found terms Cooling Power Potential (CPP). The CPP (façade) indicates could increase average 20% at 55°C, is typical temperature façades during summertime. In future, it would explore advanced radiative cooling capabilities combined atmospheric transparency windows.

Ultra‐Efficient Passive Daytime Radiative Cooling Enabled by Dual‐Selective Inorganic SiO₂/Si₃N₄ Photonic Emitter

Laser & Photonics Review, Journal Year: 2025, Volume and Issue: unknown

Published: March 20, 2025

Abstract Radiative cooling is a zero‐energy technology that enables subambient by emitting heat into outer space (≈3K) via the atmospheric transparent windows. However, existing designs predominantly focus only on primary window (8–13 µm) and neglect another (16–25 µm), underutilizing their potential. Moreover, widely utilized organic radiative metamaterials face significant challenges, including oxidation, degradation, delamination, which ultimately reduce operational lifespan. In this work, dual‐selective emitter demonstrated based an inorganic multilayer SiO 2 /Si 3 N 4 photonic structure. Outdoor experiments demonstrate achieves notable (≈12.6 °C) power of 141.4 under solar irradiance over 900, exceeding performance thermal emitters. emitter's substantial application potential revealed in building energy conservation with estimated annual savings ≈129.1 hot climates through numerical simulations, thereby facilitating meaningful reductions fossil fuel consumption greenhouse gas emissions. This work offers scalable practical solution for sustainable management superior performance.

Towards practical applications of radiative cooling

Published: March 26, 2025

Radiative cooling (RC) technologies channel excess heat into outer space or cooler environments, potentially mitigating high temperatures in the built environment. However, despite progress research, transition from laboratory breakthroughs to widespread practical deployment remains challenging. In this Review, we aim bridge gap between theoretical studies and implementations of RC technology. Developments material science system architectures have begun facilitate transformation technology innovations towards real-world applications. We analyse three representative applications with different operation temperatures: thermal management buildings (sub-ambient temperature), personal comfort (near-ambient temperature) solar-cell (above-ambient temperature). also discuss current challenges opportunities encountered advancing for commercial use, such as ensuring that are economically viable, can be produced on large enough scales meet demands desired application perform effectively a range environments weather conditions. For uptake occur, collaboration among researchers, engineers industry stakeholders is needed design sustainable scalable manufacturing processes develop standardized protocols evaluating performance materials. passive approach could reduce reliance air conditioning. This Review outlines challenges, radiative control buildings, people solar cells.
