4. BIOS Philosophy
Stable section ID: S05-CON-006-SECTION-5 · 24 content blocks
The Building BIOS Philosophy is founded upon the principle that a building shall know its verified configuration before it permits intelligent operation.
The BIOS shall be:
- Local-first: essential functions remain available within the building.
- Vendor-neutral: no single manufacturer controls universal building configuration.
Configuration-authoritative: approved configuration is distinguishable from observed or requested configuration.
- Interface-based: components are coordinated through declared Interfaces and capabilities.
- Deterministic at the core: identical verified inputs and rules produce predictable decisions.
Human-accountable: safety-critical configuration changes remain attributable to authorized persons or institutions.
Machine-readable: robots, software, AI, and engineering tools can interpret configuration without relying on unstructured documents.
- Recoverable: configuration and essential records can be restored after equipment or power failure.
- Traceable: changes, commands, states, faults, and overrides produce persistent records.
Replaceable: the BIOS implementation can migrate to new hardware without losing the building’s identity or history.
Extensible: new component classes and services can be added without redesigning the constitutional architecture.
Fail-safe: uncertainty, inconsistency, or loss of trust results in restricted behavior rather than uncontrolled activation.
The BIOS shall prefer verified evidence over assumption. Physical presence shall not imply compatibility. Network connectivity shall not imply authorization. A command shall not imply successful physical action. A digital model shall not imply that the corresponding physical configuration exists.
The BIOS shall maintain explicit separation among:
what was designed;
what was manufactured;
what was installed;
what was commissioned;
what is currently observed;
what is currently authorized;
what is requested;
what is predicted.
