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