7 months ago Agreed. I have updated the timestep in all global.pxv files to align with EnergyPlus recommendations. Additionally, I have added it locally to gitignore to prevent it from being pushed to the remote repository when we use an hourly timestep to expedite model reviews.
While testing the commercial models, I observed that the general.pxt file includes a parameter for timestep, with a default value of 4. While this is consistent with commercial CBECC and is sometimes recommended if timestep outputs need to align with 15-minute utility meter data, the EnergyPlus I/O Reference recommends 6 timesteps/hr minimum for HVAC simulations (See EnergyPlus V22.2 Input-Output Reference Manual, page number 45). Notwithstanding this distinction, it currently appears that any timestep defined in the global.pxt is being overridden by the "TIMESTEP=1" entry in the global.pxv file for commercial models. If I comment out the timestep in global.pxv, the "TIMESTEP=4" value from global.pxt is successfully used. I'd suggest that the global.pxv be modified to remove or comment out the TIMESTEP variable, unless these models are still being debugged.
