INDUSTRY ARCHITECTURE / Real estate & facilities

Real estate & facilities architecture

A connected reference design spanning domain information, data engineering, AI services, agent execution, and governance.

DOMAIN DESIGN DECISION

The business context
shapes the architecture.

A maintenance request may use a room name rather than an asset identifier, while energy comparisons depend on occupancy and operating schedules.

Resolve building and asset hierarchy, standardize meter units and intervals, and retain occupancy and schedule assumptions.

Start with facilities service intake rather than attempting to automate the whole industry at once. Define a bounded request, the evidence required to answer it, and the person accountable for accepting the result.

DATA → AI → AGENTIC AIDOMAIN CONTEXT: Building / Asset / Service request / Meter reading

Data architecture

01
Domain sources
Building manuals, asset registers, service tickets, energy readings. Identify the system of record, owner, refresh rate, and approved purpose for each source.
02
Ingestion & contracts
Batch, change-data capture, events, and document intake as appropriate. Validate schema, identity keys, event time, and rejected records.
03
Storage & transformation
Separate raw evidence, validated records, and curated domain products. Preserve version history and reconciliation results.
04
Semantic serving
Building · Asset · Service request · Meter reading. Publish agreed definitions, access rules, and reusable interfaces for analytics and AI.

AI architecture

01
Approved information
Use curated domain products and approved documents. Preserve metadata, effective dates, and access scope.
02
Retrieval & features
Build permission-aware retrieval indexes or model features for the specific task. Test relevance and freshness independently.
03
Model & evaluation
Evaluate candidate methods on representative domain examples. Check groundedness, completeness, uncertainty, cost, and failure behavior.
04
Experience & feedback
Serve sourced drafts or scored signals through a review experience. Capture feedback without silently retraining or widening data access.

Agentic AI architecture

01
Task & identity
Record the initiating user, allowed purpose, task boundary, and completion criteria.
02
Reasoning & state
Facilities service agent and Energy insight agent. Keep task state, retrieved evidence, and unresolved questions traceable.
03
Scoped enterprise tools
Expose typed, permission-checked search, lookup, and draft tools. Validate arguments and handle retry or timeout safely.
04
Approval & audit
Building controls, contractor commitments, and safety actions require operator approval. Record tool calls, reviewer decisions, and the accepted result under an agreed retention policy.

Implementation decisions
to resolve before build.

Data lifecycle

Identify authoritative records, history requirements, update frequency, retention, and the consequences of stale information. Preserve source event time and ingestion time where ordering matters.

Serving & integration

Choose batch, event, API, or document access based on workload needs. Separate read-only retrieval from tools that alter enterprise records. Define timeouts, retries, and recovery ownership.

Operational evidence

Measure asset resolution accuracy, request completeness, anomaly review usefulness, and approved work-order quality. Keep versioned evaluation cases, end-to-end traces, and reviewer feedback so changes can be assessed against an agreed baseline.
