How Hank uses AI[2][5][4]
Hank plugs into a building's existing automation system and builds a cloud digital twin, then uses machine learning to make continuous micro-adjustments to HVAC and equipment in real time. It autonomously controls building systems to cut energy use while holding occupant comfort and air quality.
- • Builds a digital twin of the building from its existing automation system and learns how equipment behaves
- • Applies machine learning and energy modeling to adapt HVAC settings to occupancy, weather, and equipment performance
- • Runs autonomous, remote control of HVAC and related systems rather than fixed schedules
- • Flags equipment inefficiencies and predictive maintenance needs across the portfolio
AI type: Machine learning and energy modeling with autonomous control (digital twin)
Key numbers[2][5]
- • Reports up to roughly 30% reduction in energy consumption, with an average around 20% energy reduction after implementation
- • Plugs into existing building systems and reaches full autonomous control within about 14 days
- • Integrates with ENERGY STAR Portfolio Manager for recognized energy ratings
