Abstract	The increasing frequency of extreme heat events, rapid urbanisation, and growing demand for building cooling are creating significant challenges for energy systems and urban infrastructure. Passive cooling provides an important pathway for reducing building energy consumption while improving indoor thermal comfort and resilience to heat. Recent advances in materials science have expanded the range of passive cooling technologies beyond conventional insulation and reflective surfaces to include radiative cooling materials, phase-change materials, advanced thermal insulation, cool coatings, thermochromic materials, porous materials, aerogels, and bio-based composites. This paper examines emerging advanced materials for passive cooling and evaluates their potential applications in energy-efficient buildings and urban climate adaptation. A conceptual qualitative methodology is adopted to analyse material properties, cooling mechanisms, building applications, environmental benefits, and implementation challenges. The study proposes an Integrated Advanced Materials Passive Cooling Framework combining solar reflectance, thermal emittance, heat storage, insulation, ventilation, and urban-scale heat mitigation. Particular attention is given to daytime radiative cooling, phase-change thermal storage, high-performance insulation, reflective façades and roofs, and nature-inspired materials. The analysis indicates that no single material can provide optimal cooling under all climatic conditions; rather, climate-responsive combinations of materials, building geometry, ventilation, shading, and thermal storage are required. Key challenges include durability, optical degradation, moisture sensitivity, manufacturing costs, environmental impacts, fire safety, material recyclability, and performance variability under real-world conditions. The paper concludes that advanced passive-cooling materials can contribute significantly to low-energy buildings and urban heat adaptation when integrated into climate-responsive architectural and infrastructure strategies.
