Building BIOS Architecture

10. Universal Building BIOS Model

The Universal Building BIOS Model consists of five principal entities:

Physical Building The structural, mechanical, electrical, fluid, environmental, and spatial systems.

Registered Engineering Assets Nodes, Interfaces, Cartridges, equipment, sensors, controllers, and passive components represented within the BIOS.

BIOS Core Services Identity, configuration, state, event, policy, security, storage, and recovery services.

Higher-Level Systems Building Management Systems, home automation, Digital Twins, AI agents, engineering applications, and robotic systems.

Human Authorities Owners, occupants, engineers, installers, inspectors, maintainers, emergency responders, manufacturers, and administrators.

The BIOS receives:

identity records;

Digital Interface Descriptors;

Cartridge Digital Passports;

physical observations;

commissioning evidence;

sensor states;

configuration requests;

Engineering Profiles;

user and service commands;

higher-level system requests.

The BIOS produces:

verified topology;

approved configuration;

compatibility decisions;

authorized service access;

state and event records;

configuration-change records;

diagnostic information;

fault and restriction status;

recovery data;

controlled APIs.

The authoritative BIOS configuration shall be represented as a versioned graph of entities and relationships rather than merely as a list of devices.

Each registered entity shall have:

identity;

type;

version;

location;

interfaces;

capabilities;

requirements;

state;

dependencies;

permissions;

evidence;

lifecycle status.

Each relationship shall identify:

participating entities;

relationship type;

direction;

Interface IDs;

current status;

effective configuration version;

applicable evidence.
