<p class="MsoPlainText"> <o:p></o:p></p>
<p class="MsoPlainText">You won’t see heating and cooling energy unless you create plants and assign the heating and cooling coils to the respective plants. You can have one system in TRACE that provides both heating and cooling (fan coil units, heat pumps,
VAV systems, etc.) and assign your rooms to that system so that you don’t have to choose between either heating or cooling for each room.<o:p></o:p></p>

<p class="MsoPlainText"> <o:p></o:p></p>
<p class="MsoPlainText">I have created rooms within Trace 700 and then I created two different systems (cooling and heating). I can add my rooms only to either cooling or heating. How can I add rooms to both heating and cooling? Previously I had only cooling
system yet the report showed both heating and cooling loads. However I did not give me energy results which is why I created a separate heating system hoping it would give me energy results as well since one of my past projects had only heating system and
it did give me energy results.<o:p></o:p></p>
