This is answered by the readme.md at https://github.com/NREL/OpenStudio-BuildStock:
- Versions 2.2.5 and prior support the use of the publicly available OpenStudio-PAT software as an interface for deploying simulations on cloud computing. Read the documentation for v2.2.5.
- Versions 2.3.0 and later only support the use of buildstockbatch, which is not yet publicly available, for deploying simulations on high-performance or cloud computing.
