<p>Jacopo,</p>
<p> I think you would take the energy transfer outputs from the
radiant floor model and impose them on Type690 as part of the
sensible load on the space. Basically your radiant floor would
augment or diminish the instantaneous gains that are already
computed for your space.<br>

<p>Jacopo,</p>
<p> This is a little bit tricky; the problem is that the loads
you have are presumably instantaneous heating and cooling
loads. If your delivery device were something without a lot of
thermal mass (like zonal heat pumps or some fan coils) then I
would recommend that you impose the loads directly onto the
liquid stream. However, the radiant floor has a lot of thermal
mass of its own. I think the best approach would be to impose
your loads on a lumped capacitance that is tuned to mimic the
zone. Then you can define a radiant floor using Type653 in
order to control the temperature of the lumped capacitance
that has your original building loads imposed upon it.</p>
<p>kind regards,</p>
<p> David</p>
