Hi Mohammad,
Yes, the ZONE:AUX-HEAT-RATIO was on my list and I use a custom default expression for that.
What is the issue with occupancy keywords?
Thanks,
~Bill

Hi Bill,
I’m not aware of a specific tool that can handle that conversion automatically, but the following approach should save you some headaches.
You’ll likely encounter errors when converting from version 2.2 to 2.3 due to differences in occupancy keywords and the addition of auxiliary heating ratio for baseboards. To minimize those issues, try this:
1. Remove the occupancy schedules and their associated sensible and latent values (leave those fields empty).
2. Open the model in version 2.3 (build 7175) and set the auxiliary heating ratio value to 0 (I had models with errors when set to 1)
3. Once the file opens properly, re-enter your occupancy schedules and values.
Hopefully this helps smooth the process a bit.
Kind regards,
Mohammad

Does anyone have a handy how-to or cheat sheet (or tool!) for converting DOE2.2 models to DOE2.3? It’s been a few years since I’ve done the exercise. Happy to share my old notes on the subject.
