• Surface Outside Face Net Thermal Radiation Heat Gain Rate per Area [W/m2]
• Surface Outside Face Net Thermal Radiation Heat Gain Energy [J]

Documentation

These “outside face net thermal radiation” output variables describe the heat transferred by longwave infrared thermal radiation exchanges between the surface and the surroundings of the outside face. This is the net of all forms of longwave thermal infrared radiation heat transfer. The values can be positive or negative with positive indicating the net addition of heat to the outside face. Different versions of the report are available including the basic heat gain rate (W), and a per unit area flux (W/m2), and an energy version (J).
