Solar reflection and thermal emission work together
Passive radiative cooling materials affect surface heat balance through solar reflection and thermal radiation. The mechanism does not guarantee a fixed temperature or energy reduction at every site. Verify test reports, controls and operating conditions.

MATERIAL / SUBSTRATE
01 / Sunlight
Review reflectance test methods and substrate conditions.
02 / Heat radiation
Review emission measurements and spectral range; separate material data from system results.
03 / Field validation
Define control surfaces, sensors, monitoring period and energy baseline.
