<p>Ilyas,</p>
<p> I generally use a value that is 5 times the default. As Toni
correctly pointed out the default accounts only for the thermal
capacitance of the air contained in the thermal zone.</p>

<div>Hello.</div>
<div>I have a question about the capacitance of TRNSYS zones.</div>
<div>I see in the TRNBUILD that the value by default to
calculate the capacitance (volume of the pieces * 1.2). it's
logic ?. thank you.</div>
