Radiant Asymmetry

The difference between the plane radiant temperature of the two opposite sides of a small plane element. When you stand in front of a campfire or a cold window you are experiencing radiant asymmetry. Shown are the recommended limits for thermal comfort which includes the limits when using radiant walls and ceilings.
