I have problem with realistic radiative heat transfer during the
simulations. I need information about deeferent value of hr for external
and internal walls
PREBID calculates a standard u-value by using a combinated heat transfer coefficients. These are 7.7 W/m²K for inside surfaces and 25 W/m²K for external surfaces. the standard combinated heat transfer coefficient are used only to display the wall U-value, becouse in simulations the convective and radiative heat transfer coefficinet are evaluated separately. Mazbe sameone know how I can get evalueted coefficient_ Thnks for help
with regards
Dorota
