Building BIOS Architecture

The Building BIOS boundary defines what the BIOS controls directly, what it coordinates, and what remains under the authority of other systems.

The BIOS controls directly:

its own trusted startup;

its authoritative configuration records;

component enrollment;

access permissions;

configuration validation;

state and event records;

service activation;

API access;

configuration backup and recovery.

The BIOS coordinates but does not automatically replace:

structural safety systems;

electrical protective devices;

mechanical interlocks;

fire-alarm control units;

pressure-relief systems;

certified safety controllers;

Building Management Systems;

home-automation systems;

robotic controllers;

Digital Twin platforms;

AI services.

The BIOS may authorize a higher-level system to issue commands, but the receiving physical controller remains responsible for executing those commands within its certified limits.

The BIOS shall not perform project-specific engineering design simply because it possesses configuration data. Engineering Compiler or AI services may analyze proposed configurations, but final authority shall follow the project’s engineering and regulatory requirements.

The BIOS shall not claim that the Digital Twin is synchronized unless required physical verification has occurred.

Cloud services may extend storage, analytics, remote support, and collaboration, but shall not become the sole holder of essential building identity or recovery information.

Manufacturer services may support their products, but shall not receive unrestricted access to unrelated building systems.
