Solar radiative heating
WebDec 26, 2024 · The ideal spectral range for solar heating is the one with a high α and low ϵ. Conversely, for daytime radiative cooling, the solar spectrum should have high solar reflectance and ϵ in the range 8–13 μm. Efficient heat management requires coordinated multispectral regulation (mainly visible, near-IR, and mid-IR).
