I have been trying to setup the OpenStudio residential workflow and am getting stuck on the final measure - HVAC Sizing. I setup the workflow as defined here: https://github.com/NREL/OpenStudio-BE... in PAT. The error I am getting states that:

"undefined method -' for nil:NilClass\n\tC:/AWS/Residential WorkFlow/temp_data/analysis_bfc74e65-b296-449b-9651-c706bc039376/measures/ResidentialHVACSizing/resources/geometry.rb:362:inget_height_of_spaces'

I dug deeper into it and it appears that none of the spaces are showing up as conditioned, so no height is populated meaning the system can't be properly sized. Has anyone run into this issue before or had issues with the HVAC sizing measure when trying to run the whole residential workflow?

Did you create your own building geometry or did you use the geometry measure?

I used the one that could be synced directly off of the BCL from PAT. It is the same measure as that but from a different location.

Can you zip up your PAT project and upload it or email it to me?

I realized yesterday that I had gotten all my measures from the BCL except the HVAC sizing measure which I got from the Github page. I then recreated a project just using the Github project measures only and it works!

For what it's worth, I think the HVAC sizing measure on the BCL got corrupted or something. I re-uploaded it to the BCL, so the measures there should work again. You can continue using the measures on the GitHub repo, which are more up to date, but be aware that they have been tested less rigorously.
