Hi,
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.
