not as a adjustable Parameter within TYPE56 for internal surfaces - all
walls, windows have e=1. For external surfaces: walls have e=0.9 constantly, but
the emissivity of windows pos. 1 is taken into account from the values given in
the w4lib.dat.</FONT></SPAN></DIV>
<DIV><SPAN class=358380319-28112004><FONT face=Arial color=#0000ff size=2>For
other emissivities than e=1 of internal surfaces you might use a way around by
calculating the radiant heat exchange with different emissivities and than
distribute the gains & losses of the surfaces with the "Wall
gain" input.</FONT></SPAN></DIV>
