Authors

Created by University of Hawaii at Manoa students: Elijah Saloma and Jake Dickinson, advised by Samir Boussarhane.

In collaboration with MITRE Caldera™ for OT (ot@mitre.org).

HVACSim is intended to grow open source collaboration in OT. We encourage forks and pull requests with improvements, new features, deployment notes, documentation, and tests.

The students’ original version is preserved in the v1.0.0 release.
