How PassiveLogic uses AI[1][2]
Autonomous building control runs on the edge through PassiveLogic's Hive platform, which uses physics-based 'Quantum' digital twins and a differentiable AI compiler to optimize HVAC and energy in real time.
- • Quantum digital twins model a building's zones, weather, and mechanical physics
- • Hive runs millions of simulations in seconds to pick optimal control paths for the hours ahead
- • Edge hardware (12-core processor plus on-board NVIDIA GPU) keeps decisions local, no cloud required
- • Differentiable Swift compiler trains models at the compiler level; PassiveLogic reports 322x faster than TensorFlow and 238x faster than PyTorch on a building thermal model
AI type: Physics-informed AI, Differentiable Programming, Digital Twins, Predictive Control, Edge AI
