<p>You can set the value to whatever you like; the field is in the
information window for each airnode of the building in TRNBuild.
The default value (1.2* volume) accounts only for the thermal
capacitance of the air in the airnode. Typically the default value
is multiplied by some factor between 5 and 10 to account for the
thermal capacitance of all the furnishings in the zone.</p>

<div style="margin:0;"> In the 05-MultizoneBuilding
document, The capacitance will be automatically set to a
default value of 1.2*volume. Can the capacitance value be
changed to 0.5*volume or 0.8*volume？</div>
