Smart building monitoring — connected sensors that make a building legible
A smart building is one whose operators see how it is actually performing — environmental conditions, occupancy patterns, ventilation effectiveness — and act on that data. Monitoring is the layer that makes it possible.
Data layers
What a smart building monitoring system measures
The most useful systems combine environmental, occupancy and performance data so each stream gives the others meaning.
LAYER 01
Environmental conditions
CO₂, PM2.5, TVOC, temperature and humidity per zone — the basis of indoor environmental quality.
LAYER 02
Occupancy & utilisation
Anonymous people-counting and presence sensing to relate environmental data to actual use.
LAYER 03
Ventilation performance
Supply-air flow, filter pressure, damper position and outside-air fraction — turning HVAC into observable data.
LAYER 04
Integration & analytics
BMS write-back, energy correlation and trend analytics to inform setpoints, maintenance and capital decisions.
Operations
Why smart building monitoring earns its keep
Demand-controlled ventilation. Real-time CO₂ and occupancy data let the system raise outside-air supply only when needed — improving environmental quality and reducing energy consumption.
Targeted maintenance. Pressure-drop trends across filters and supply-air temperatures flag developing issues before they become complaints, allowing planned interventions instead of reactive callouts.
Evidence for capital decisions. Year-on-year monitoring data supports the business case for ventilation upgrades, filtration improvements and certifications such as WELL or BREEAM In-Use.
Deployment
A practical retrofit pathway
- 1
Phase 01
Baseline survey
Two- to four-week temporary deployment to map current performance and identify priority zones.
- 2
Phase 02
Permanent sensor network
Wireless sensors installed in critical spaces, with secure gateway connectivity.
- 3
Phase 03
BMS integration
Data shared with the BMS via BACnet, Modbus or REST API; demand-controlled ventilation enabled where appropriate.
- 4
Phase 04
Operational review
Quarterly performance review using trend data, calibration cycle and continuous improvement actions.
