<div><span style="color: rgb(33, 33, 33); font-family: "Times New Roman", Times, serif; font-size: 16px; white-space: pre-wrap;">I too had the same problem on TRNSYS. You have heavy walls and you find a weak inertia. so you have to change the default capacitance
of TRNSYS which is (r * c * v air and it does not consider the furniture) thereafter it is necessary to multiply this capacitance by 5 until by 10. and you can see the difference.</span></div>

<div dir="ltr">Hi,
<div>I'm running some simulations for a single-family house with TRNSYS and one of my purposes is showing that the program takes into consideration the effect of thermal inertia into its calculations. I have two building models, "light" and "heavy" (the first
one modelled through massless layers) with more or less the same characteristics as concerns trasmittance. If I force a sinusoidal temperature profile for outdoor temperature, I can appreciate the delay and damping effects looking at the temperature profile
of the heavy building internal wall surface. However if I plot the heating demand as well (given by the heating type set in TRNBuild) for the heavy building I see that power is not in synch with wall internal temperature. At first I thought that it was due
to the storage effect of walls, but the heating type is modelled as 100% convection, so the walls shouldn't influence the phenomenon dynamics this time. Am I missing or neglecting something? Thanks in advance for your answer.</div>
