You can force a constant zone temperature in ResStock v2.2.4 models by using the measure Ideal Air Loads Zone HVAC. There are some additional edits you need to make to the osm in order to implement Ideal Air Loads Zone HVAC, including deleting Energy Management System (EMS) objects and rewriting ResStock's default heating and cooling setpoints. These are legacy objects from the existing HVAC system in the IDF that the Ideal Air Loads Zone HVAC measure removes. If the simulation is run with EMS objects and Ideal Air Loads objects in the same IDF, it will fail.
The Ideal Air Loads Zone HVAC measure "will replace the existing HVAC system with ideal air loads objects for each conditioned zone." It can be found and downloaded here: https://bcl.nrel.gov/node/84744
I created a measure Clean_ResStock_for_Ideal_Air_Loads that, if placed before the Ideal Air Loads Zone HVAC measure in PAT, allows Ideal Air Loads to work with the ResStock workflow. Please contact me at sashadf@postroadfoundation.org if you would like to see it.
