COMPARATIVE EVALUATION OF RADIATIVE COOLING MATERIALS IN THE BUILT ENVIRONMENT: INFLUENCE OF APPLICATION METHOD ON COOLING PERFORMANCE

Abstract

This study delves into the impact of application methods on the performance of radiative cooling materials within different climatic contexts, focusing on films, coatings, and paints. Using data gathered from research articles, the research examines how these application methods influence cooling efficiency, measured by cooling power and sub-ambient temperature achievement. Initial Analysis of Variance (ANOVA) tests suggest no significant differences in cooling performance based on application methods within specific climate categories, implying that factors other than the application form play a critical role in material efficacy. However, subsequent regression analysis reveals a nuanced relationship, indicating that films and coatings are significantly more effective than paints in enhancing cooling power. The study underscores the importance of considering both the application method and climatic conditions in selecting radiative cooling materials for sustainable building design. The findings highlight the complex interplay between material science, architectural design, and environmental engineering in optimizing the cooling performance of materials for energy efficiency. This research contributes to advancing our understanding of sustainable cooling technologies, offering valuable insights for architects and engineers aiming to integrate energy-efficient solutions into the built environment. As the quest for sustainable building technologies continues, this study provides an examination of the factors influencing the effectiveness of radiative cooling materials, paving the way for future research in this area.
