There are a lot of factors that could be contributing (different
wall material properties between the simulated and "real" wall,
different solar absorption coefficient for the wall, different
convection/radiation split, etc.) I would also recommend that you
read in the Type56 manual about how it treats radiation gains to a
surface and what wavelengths are included.<br>

try to simulate the heating that a lamps panel provides
to a wall. In order to do that, I measure both the
incident radiation that
arrives to the wall and its temperature. However, after
giving TRNSYS the measured
radiation value, the wall temperature I get in the
simulation is sensible lower
than in the real wall. Any help about this?<o:p></o:p></span></font></p>
