Hi @Shanice,
Honestly I’m finding it a little tricky to follow without being able to dive in and interrogate results myself - I’d be happy to have a quick look at your script and IES model if you’d like (I’ve been doing my own tests recently to understand differences between HB and IES results so it’s useful learning for me). You’re welcome to send them to me in a private message if you’d prefer not to post them completely publicly.
If the U-values are the same in both it might be worth trying to copy the construction build ups as closely as possible between the software to reflect where the thermal mass and insulation lies within the construction. That may have some effect. Also checking the external solar reflectance / absorption properties in both might help align them.
From what you’ve posted it looks like there’s more loss at night from the Rhino model, so agree it’s strange to see the temperatures increase overnight rather than decrease.
The behaviour in the evening suggests that the heating set point in your IES model drops at 5pm, whereas it looks like it might stay the same in you Rhino model as it is during the day. Although worth noting that Chris has just changed how external conduction gain is being reported in HB to align with IES, perhaps you don’t have the latest version that includes that change?
Details of that here:
The energy model provided by Chris makes sense to me. I’m guessing that there’s a set back temperature of ~15C in that model, but I’ll have to check in GH when I’m at my laptop tomorrow.
Sorry this doesn’t really get to your problem, but hopefully the discussion helps the process of finding the difference.
Cheers,
Charlie
