<div dir="ltr"><div><br></div><div>Hi Alain,</div><div><br></div><div>I guess that you are calculating the heating load with unlimited heating power. If that's the case, you are requesting to type 56 that the building reach the setpoint
temperature
in 1 minute (that might be lot of energy for such a small amount of time) and the sudden peaks in the heating load appear at times where you have a change in the setpoint temperature. I will suggest that you use a limited power for your heating device, or increase your time step to a time that you find reasonable to heat your building. In general, smaller time steps are "better", but if you are just interested in calculating your heating load that's not necessarily true, specially if you are interested in calculating peak power. Hope it helps, best regards</div><div><br></div><div>Angel<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">El mar, 28 sept 2021 a las 10:44, Alain GUIAVARCH via TRNSYS-users (<<a href="mailto:trnsys-users@lists.onebuilding.org">trnsys-users@lists.onebuilding.org</a>>) escribió:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
