If my memory does not fail me, there is a test report that says to use DOE-2 algorithm for outside surfaces. This includes turbulence.
For inside surfaces, eg walls, use Detail.
Horizontal surfaces are more difficult, as coefficients for upward heat flow and downward heat flow is different. Some values are given ihe Example idf file -basement.
Does energyplus actually separate the radiative heat flow from the convective heat flow. The Basement preprocessor also have different fields for entering 'convective' and 'convective and radiative' coefficients, for upward and downward flow.
my question is : The radiative coefficent apply only to certain spectrum?
