I designed a plant loop for a small house with radiant heating and cooling equipment for a single zone as shown in Figure 1 (district heating/cooling + low-temp radiant variable).

Open studio simulation worked, but the result showed no heating and cooling load for the zone (figure 3). I struggled for fixing this trouble, but no answer for now. I guess my problem is involved with setting up schedules for the radiant system and the plant loop. Can you suggest any insightful idea for me?? Thanks very much!

@Jlove (love the handle), no need to preface question with [openstudio] if it is one of the tags. :)

Figure 3 shows just electric and gas consumption. With district heating and cooling you don't know the fuel so it doesn't show up in either of those graphs. If you scroll further down in your results you will see tables for both district heating and cooling. In the future we do plan to have graphs for them, but for now they just have tables.

Note: The same thing happens if you you using ideal air loads in early design.
