On April 21, 2026, a professional platform released a collection of articles on thermal insulation coatings and radiative cooling coatings, systematically sorting out principles, calculations, evaluations and application differences to provide authoritative references for the industry. The collection confirms that such coatings deliver effective cooling, yet performance varies greatly by scenario and demand: industry focuses on heat dissipation, while buildings prioritize energy saving, and energy savings differ from heat dissipation capacity. Radiation dominates heat loss in space, but conduction, radiation and convection coexist on Earth, leading to huge differences in heat transfer. The content covers core topics such as thermal insulation mechanisms, thermal calculations, performance evaluation, application differences between roofs and walls, and atmospheric window effects, with quantitative analysis based on standards like GB50176, combining theoretical depth and engineering practicability. This collection provides a complete technical framework for R&D, design and application, promoting the efficient deployment of passive cooling technologies under the carbon neutrality goal and supporting greener development in construction and industry.
