Building BIOS Architecture

The Capability Registry records what building entities can provide, require, receive, control, measure, or tolerate.

Capabilities may relate to:

structural resistance;

mechanical movement;

electrical power;

fluid supply or discharge;

thermal performance;

sensing;

communication;

control;

computation;

robotic handling;

safety and emergency functions;

environmental resistance;

human accessibility.

Each capability record shall include:

Capability ID;

capability type;

providing or requiring entity;

Interface through which it is available;

direction;

unit;

nominal value;

minimum and maximum values;

accuracy or uncertainty;

operating conditions;

capacity duration;

dependencies;

safety classification;

evidence reference;

current availability;

applicable configuration version.

The Registry shall distinguish among:

declared capability;

certified capability;

design-required capability;

negotiated capability;

measured capability;

degraded capability;

unavailable capability.

A manufacturer-declared maximum shall not automatically become the building’s authorized operating limit. The active limit shall be the lowest applicable verified restriction from the component, Interface, project design, Engineering Profile, host system, current condition, and policy.

Capabilities may be aggregated only through approved rules. Capacities of parallel components shall not be added if common dependencies, flow limits, control conflicts, or failure modes prevent simultaneous delivery.

When a component degrades, the Registry shall update its currently available capability without altering its historical certified capability.
