@ejhw @afontani @aspeake

This is the first item from https://trello.com/c/0lwzEytE/76-port-os-hpxml-fixes-over-to-develop. So for example do we want to go ahead and merge this? Or do we first want to compare each of these items to resstock-hpxml?

[ejhw]

@joseph-robertson I don't see any benefit to comparing to resstock-hpxml before we merge. Probably want to do a separate EULP run for this change. cc @afontani

There's a bit more to do on this one.

The CI only shows simulation results changing for samples w/ room ACs, and they change in the expected way. I also compared the performance curves and coil COP in a single ResStock IDF to an OS-HPXML IDF and they match. This looks good to me.

[joseph-robertson]

We should go ahead and merge this into develop, and then @afontani can do his EULP runs.
