Turning Information Into Intelligence
In the 360 Smarter Stack, Layer 5: Data & Context is where the smart office begins to think.
Modern buildings already generate huge volumes of data — from sensors, scheduling platforms, environmental systems, user devices, and digital services. But data alone is not intelligence. Without interpretation, it is noise. Without shared meaning, it is fragmented. Without context, it cannot drive useful action.
Layer 5 focuses on how we structure, tag, relate, and operationalise data, transforming it from raw signals into insight and automation that improve performance, sustainability, and the user experience.
This is where the building stops reacting and starts reasoning.
Building a Contextual Data Model
A contextual data model moves us from disconnected data points to a unified system of meaning. It allows every asset, space, and interaction to be understood not just as data, but as part of a bigger behavioural and operational picture.
At the core of this model are three foundational capabilities:
✅ Data Tagging
✅ Semantic Layers
✅ Interoperability
Together, they define what the data is, how it relates, and where it can be shared to support automation and insight.
Data Tagging — Structuring the Fundamentals
Data tagging is the process of assigning metadata to sensors, devices, equipment and spaces so systems understand what they are interacting with.
For example, a CO₂ sensor could be tagged as:
| Attribute | Value |
|---|---|
| Building | HQ |
| Floor | 3 |
| Zone | West |
| Space Type | Meeting Room |
| Device Type | CO₂ Sensor |
| Function | Air Quality Monitoring |
When every device follows a consistent tagging standard (e.g., Project Haystack), the building becomes easier to navigate, automate, diagnose, and scale.
Tagging enables the system to answer questions like:
- Where is this happening?
- What equipment is involved?
- How should I respond?
It makes automation repeatable, maintainable, and future-proof.
Semantic Layers — Making Meaning Machine-Readable
While tagging identifies what the data represents, a semantic layer defines how different data points relate to each other.
This is what allows systems to reason logically:
- Room A belongs to Floor 2
- Floor 2 has a “Client Meeting Zone”
- The zone is linked to specific comfort rules and service levels
Ontologies like Brick Schema, RealEstateCore, and IFC provide structured ways to model spaces, devices, and relationships.
Semantic models enable smart office use cases such as:
| Scenario | Enabled by Semantic Context |
|---|---|
| Turn HVAC off when booked room becomes unoccupied | Understanding space + purpose + occupancy + controls |
| Correlate productivity and comfort | Linking booking data + CO₂ + temperature + user feedback |
| Personalised environmental preferences | Recognising who is using which space and how |
This is the step where the building understands context, not just conditions.
Interoperability — The Backbone of Integration
Even the best-tagged and modelled data fails if it cannot be used across systems.
Interoperability ensures data is movable, readable, and actionable, regardless of vendor.
This typically involves:
- Common protocols (MQTT, BACnet, KNX, OPC UA, REST APIs)
- Middleware platforms to translate and unify data flows
- Data normalisation to ensure consistent naming and units
Interoperability does three important things:
- Prevents vendor lock-in
- Supports modular scaling
- Enables true automation across building systems
This is how a room booking triggers HVAC, lighting, access permissions and cleaning schedules — automatically and intelligently.
From Data to Insight — Making the Building Adaptive
Once data is tagged, contextualised, and interoperable, it can now be analysed — both in real-time and historically.
Historical Data helps us understand:
- Space utilisation trends
- Seasonal energy loads
- Wellbeing and comfort patterns
- Long-term maintenance behaviour
This informs strategic planning (e.g., downsizing, redesigning work zones, investing in retrofit).
Real-Time Data enables:
- Live occupancy awareness
- CO₂ and air quality balancing
- Predictive maintenance alerts
- Dynamic space allocation
This enhances experience and operational efficiency in the moment.
Together, they enable:
- Predictive intelligence (anticipating needs)
- Prescriptive intelligence (recommending actions)
This is where the workplace evolves from passive to self-optimising.
Data Governance: Trust and Transparency Matter
Smart building data must be:
- Owned responsibly
- Anonymised when appropriate
- Secure by design
- Managed across its lifecycle
Trust is a feature — not an afterthought.
Governance ensures the smart office remains not only intelligent, but ethical, secure and human-centred.
Next in the Series: Layer 6 — Integration Layer
With data now contextualised and ready, Layer 6 focuses on how systems communicate and orchestrate action across the workplace.
