The only explanation I can think of is that the changing infared flux from
the house walls to the calorimeter walls doesn't have as good a coupling to
the room air as to the solid walls of the apparatus.  This makes sense.  We
know from normal sun/earth/atmosphere interaction that 80% of atmospheric
heat is first captured by the ground and then transfered to the atmosphere by
the physical contact of the wind against the earth.

The problem is that thermometers, being solid objects, should mimic the
coupling, and hence indicate the actual temperature on the outside calorimeter
shell.  Hmm.
