In the fields of optics and heat transfer, radiosity is the total emitted and reflected radiation leaving a surface.

The diffuse radiosity (J) is the integral of the hemispherical spectral radiosity ( $J λ$ ) over the spectrum:

$J = \int_{0}^{\infty}J_{\lambda}(\lambda)d\lambda = \pi I_{e+r}$

where $J λ$ is equal to integral over the hemispherical solid angle of the sum of emitted and reflected radiant intensities.^[1]

The radiosity method is used to solve for the radiative heat transfer between a number of surfaces. This method requires the solution of a system of simultaneous equations using matrix methods because the radiation hitting each surface is determined by the temperatures of all the other surfaces.
