Mapped to a shared offline runtime family and usable with a recording or compatible ESP32 CSI stream.
Intended capability
Pilot this intended outcome through the shared Breathing rate family, then validate it against site-specific ground truth: Estimates aggregate occupant respiratory load and its spatial distribution — a leading indicator for CO2 buildup and stuffiness — enabling pre-emptive ventilation boosts and wellness-certification analytics (WELL/Fitwel) without wearables.
This describes the intended outcome. Readiness is shared-family mapped, evidence is class C, and a catalog mapping or recording is not proof of this outcome at a real site.

A related Buildings scene
This is one recorded vertical scenario. It is not separate validation of every capability in the catalog.
01 The physics
Each occupant contributes a breathing line at 0.1-0.5Hz whose collective spectral energy scales with the number of respiring people, and elevated ambient CO2/stuffiness measurably raises human respiratory rate — so the population breathing-rate distribution drifting upward is a physiological proxy for deteriorating air quality, sensed before the CO2 sensor at the return duct catches up.
02 Shared processing path
Breathing-band micro-Doppler (0.1-0.5Hz) multi-source spectral decomposition -> RTI localization to assign respiratory load per zone -> adaptive PCA baseline of the zone's normal rate distribution -> CUSUM on upward rate drift triggers ventilation boost via BMS.
This is a capability design path. Components may be shared with other catalog entries; it is not presented as a unique algorithm.
03 Validation plan
OPERAnet respiration ground truth for single/multi-person rate accuracy; own-hardware: meeting room with reference CO2 logger + respiration belts through full-occupancy meetings — test whether RF rate-drift leads CO2 rise by the hypothesized 10-20 min.
04 Commercial hypothesis
For the workplace wellness / ESG lead: 'The building senses when a room starts breathing harder and freshens the air before anyone feels it — wellness-certification evidence generated by the WiFi itself.'
