47. Building Topology Graph
Stable section ID: S05-CON-006-SECTION-48 · 46 content blocks
The Building Topology Graph is the authoritative graph representation of the building’s entities and engineering relationships.
Graph nodes may represent:
buildings and spatial zones;
structural components;
Nodes;
Cartridges;
Interfaces;
equipment;
sensors;
controllers;
services;
users or authorities;
external infrastructure.
Graph edges may represent:
physically connected to;
structurally supported by;
supplies;
drains to;
communicates with;
controls;
monitors;
located in;
hosted by;
depends upon;
protects;
isolates;
replaces;
derived from.
Every graph node and edge shall have:
unique identity;
type;
current state;
effective configuration version;
provenance;
verification status.
The topology graph shall support multiple coordinated engineering views rather than forcing all relationships into a single undifferentiated network.
The structural view shall show load-path relationships. The utility view shall show service distribution. The communication view shall show data paths. The control view shall show authority. The dependency view shall show operational reliance.
The graph shall enable queries such as:
- Which components depend upon this Cartridge?
- Which shutoff isolates this water branch?
- Which structural members transfer load through this Node?
- Which sensors inform this controller?
- Which Interfaces will be affected by removing this wall panel?
- Which systems lose operation if this BIOS node fails?
- Which emergency devices protect this zone?
Graph modifications shall occur through Configuration Change Management rather than uncontrolled direct editing.
