Abstract:
Phosphorescence (PP) has emerged as a promising passive cooling solution for the built environment, characterized by its ability to emit radiation persistently after photon absorption, thereby enhancing the solar radiation rejection capability and effective albedo of the surface. While various compounds have shown excellent properties for energy-saving purposes, assessing their benefits for the built environment towards their actual implementation still remains a challenge. To bridge the gap between laboratory-scale characterizations and real-world applications, this study employs the Princeton Urban Canopy Model (PUCM) to assess the surface cooling potential of PP coatings. This research represents the first numerical modeling of phosphorescence, extrapolating findings from experimentally validated parameters to conditions and scale of real cities. Results demonstrate the substantial capacity of PP to ameliorate surface overheating in urban areas, potentially reducing surface temperatures by up to −2.6 °C when optimized. Additionally, material optimization emerges as a crucial factor for exploiting the potential of phosphorescence in mitigating urban overheating, highlighting its strategic relevance for the urban canopy environment.
