Hi Nirmal, I have some follow up questions before I can help with your situation: 1. Are you trying to calculation peak heating and cooling loads, annual heating and cooling energy use, or both? 2. When you mention two different systems (cooling and heating), I'm assuming you are referring to air-side systems in TRACE and not plants, is that right? 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. Hopefully this helps you get closer to the solution.

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. Thank You.
