Hotel Twin · Lighting, HVAC & BMS
A fictional five-star harbourside hotel, B3 to roof, where guest-room lighting, curtains and HVAC follow check-in, occupancy and daylight. A simulated Casambi lighting network sits behind a connector that shares one device model with a future live connector; BACnet devices, a physics model and a repeatable seven-step storyline with an audit trail run in the browser.

The challenge
Hotels run lighting, HVAC and the BMS as separate systems, so an empty room is still lit and cooled. Owners want to see the integrated behaviour — and prove the lighting integration will work with the real network — before touching 277 rooms.
What we built
- Event-sourced engine with seek and clone: the same storyline replays identically every time
- Simulation / Hybrid / Live connector modes on one device model; compatibility tested separately from simulation
- Physics with provenance PHYS / EST / DEMO on every value, comfort checked room by room
- Curtains as BACnet devices and a smart-room panel; baked guest-room interiors for walkthroughs
Outcome in the twin
The storyline walks from check-in to vacant-room dimming, AI optimisation and a fault, with comfort held and a simulated saving shown as a demo figure, not a commitment.
Path to production
Run the conformance suite against a live Casambi network, connect the BMS over BACnet/IP and calibrate against metered data.
