Using Real-World HVAC Simulation in Godot for Smart Building & Climate Control Projects

Hey everyone,

I’ve been exploring ways to integrate real-world HVAC (Heating, Ventilation, and Air Conditioning) concepts into Godot-based 3D simulations for smart building projects. The idea is to visualize airflow, temperature zones, and energy efficiency in a virtual environment before applying them in real-world designs.
Has anyone here experimented with environmental or temperature-based simulations in Godot?
I’d love to learn how others handle:

Simulating airflow or temperature variation inside rooms
Managing CPU/GPU load for continuous environment updates
Integrating IoT data (e.g., from smart thermostats or AC units) into Godot scenes

I highly doubt that a game engine can be used in this way.

  • Imitation for visualization (representation) is entirely possible.
  • Simulation for modeling (calculations) is unlikely.

The physics engine here is very tentative and is not suitable for accurate modeling.

Godot supports compute shaders for hardware acceleration of things such as fluid simulations. You will probably have to roll a lot of your own implementations if you cant find one out there. I see a lot of 2d examples of fluid simulations for godot. I dont think 3d is that more complex, but you are also probably looking for heat transfer within the air, walls, and sunshine through windows?
