Building BIOS Architecture

The Building BIOS shall be responsible for maintaining the foundational digital integrity of the building configuration.

Its mandatory responsibilities include:

establishing and preserving the building’s unique identity;

verifying the integrity and authorized version of the BIOS;

initializing essential local services;

discovering connected components, Cartridges, and Interfaces;

authenticating identities where required;

retrieving or storing applicable Interface Descriptors and Digital Passports;

determining whether proposed connections are compatible;

constructing and maintaining the building topology;

recording physical, logical, spatial, and dependency relationships;

validating configuration against approved rules and Engineering Profiles;

authorizing or rejecting component activation;

tracking lifecycle and operational states;

recording configuration changes and significant events;

identifying configuration drift;

supporting diagnostics and fault containment;

controlling access to BIOS data and services;

providing authoritative information to higher-level systems;

preserving backup and recovery data;

supporting controlled replacement and upgrade;

maintaining essential emergency information.

The BIOS shall also identify where responsibility belongs elsewhere. It shall not falsely represent a monitored condition as physically protected if the required independent safety device is absent.

When BIOS responsibility is delegated to another service or controller, the delegation shall specify:

delegated function;

receiving identity;

authority limits;

validity period;

required state;

revocation conditions;

reporting requirements.
