<p>Maurice,</p>
<p> I'd recommend doing some tests to confirm to yourself that
capacitance is indeed having an impact. Start the building (or
zone) with a high temperature and just let it cool down in a
constant temperature, no solar environment. Now change the
capacitance by an order of magnitude then do the test again. The
zone should cool down either more slowly or more quickly depending
on whether you multiplied or divided the capacitance by 10. I
usually use a value of the volume*1.2*1.007*f where f is a
multiplier that ranges between about 5 and 10.</p>
<p>kind regards,</p>
<p> David</p>

When I change the volume that provides different results. By
default capacitance is 1.2*volume. But when I change, manually,
the capacitance value that gives no change. It seems that the
capacitance has no effect, whereas in the documentation it is
written</div>

<i>In order to simplify the input, default values for all
parameters except the volume are provided. The capacitance
will be automatically set to a default value of 1.2*volume.
However, it is recommended to check the default values
carefully and to adjust them if necessary.</i><br>
