Saudi Carbon Monitoring provides IAQ and BMS data assessment across Saudi Arabia, helping building operators keep interpretation of indoor air-quality sensors, ventilation trends and building-management data within the evidence. A sensor measures selected parameters at one place, and a BMS records configured points and commands. Neither automatically proves ventilation compliance, occupant health or energy savings.

Interpretation of ventilation, exposure or health questions is confirmed with a qualified MEP or IAQ specialist; our role is to scope the assessment and organise the data and evidence.
What IAQ sensors can support
Depending on the device, monitored parameters may include carbon dioxide, temperature, relative humidity, particulate matter or a TVOC signal. Trends can identify periods, zones and events for investigation. CO2 can be an indicator related to occupancy and ventilation when outdoor conditions, mixing and generation are considered.
Sensor selection, range, accuracy, response and maintenance matter. Placement near doors, supply diffusers, printers or local sources may bias the result. A measurement plan should record zone, height, nearby influences and occupied periods.
What IAQ sensors cannot prove alone
A normal reading for selected parameters does not prove the absence of all contaminants. A high TVOC signal does not identify individual compounds or establish health risk. A CO2 reading does not directly measure every outdoor-air flow. Medical and exposure conclusions require suitable methods and separate expert review.
What BMS trends can support
BMS data can show schedules, setpoints, temperatures, damper or valve commands, fan status and selected meter readings. When point identity and units are verified, trends help investigate schedule drift, control sequences and interaction with occupancy or weather.
However, a command does not prove physical position, and a displayed value does not prove sensor accuracy. Trend intervals may miss short events. Point names may be wrong after modifications. Commissioning and field checks remain important.
What energy data add
Meters and bills show energy use, while BMS and occupancy data help explain it. To evaluate a change, establish a baseline and account for weather, occupancy, schedules and equipment changes. A reduction during lower occupancy is not automatically an efficiency gain.
The ventilation, IAQ and BMS performance service defines MEP review and data controls.
IAQ and BMS data assessment: a disciplined sequence
Work through the assessment in order:
- Confirm the building question and select representative zones.
- Verify device and BMS point locations in the field.
- Trend occupied and unoccupied periods, and align indoor data with outdoor conditions, occupancy, equipment schedules and control states.
- Record special events and maintenance.
When a pattern appears, test alternative explanations. A temperature excursion may reflect a schedule, sensor location, load or equipment issue. A CO2 rise may align with occupancy but still require ventilation and mixing review. A TVOC event may be local and temporary. The MEP or IAQ reviewer determines the next check.
Evidence after a control change
Document the approved sequence, responsible engineer, commissioning checks and effective date. Compare pre- and post-change data under similar conditions or an agreed adjustment. Watch both indoor conditions and energy; do not optimise one by ignoring the other. If the evidence is inconclusive, report that result and improve measurement rather than creating a success claim. This approach makes IAQ and BMS data useful for operations while respecting their limits.
Procurement and handover
Ask bidders to state parameters, device models, ranges, installation, point mapping, trend intervals, checks, interpretation and exclusions. Confirm whether BMS work is read-only monitoring, integration or control engineering. Request original exports, location records, quality findings and analysis—not only screenshots.
At handover, the building operator should know which points are trusted, which need maintenance and which questions require further engineering. This makes the campaign useful after the consultant leaves and prevents a one-time dashboard from being mistaken for a managed IAQ programme.
For multi-building portfolios, pilot the assessment in representative assets before standardising thresholds. Climate, design, occupancy and system type affect interpretation. A common data model can improve comparison, but each building still needs its own review of ventilation and operational context.
Frequently asked questions
Who provides IAQ and BMS data assessment in Saudi Arabia?
Saudi Carbon Monitoring provides the assessment scope, data checks and handover of IAQ and BMS evidence. Engineering interpretation of ventilation and exposure questions is confirmed with the appropriate specialist.
Does low indoor CO2 or a BMS damper command prove enough ventilation?
Not by itself. Occupancy, outdoor CO2, mixing, sensor quality and system design all affect CO2 interpretation, and a damper command may not confirm physical position or delivered flow; field or engineering verification may be needed.
Can TVOC sensors identify a chemical?
Typically they provide a broad response, not compound-specific laboratory identification. Confirm the device specification.
Can sensor data certify indoor air quality, and is an IAQ monitor a purifier?
No to both. Certification and health assessment require separate criteria and expert review, and a monitor measures selected parameters while filtration or purification is a different system and engineering scope.
How should I use IAQ and BMS data assessment for a sustainability KPI?
Define the purpose, boundary and quality controls first, and state the limits of interpretation. Used that way, these data can support a sustainability KPI.
What affects the cost of IAQ and BMS data assessment?
Cost depends on the number of buildings and zones, the devices and BMS points involved, access to trend data and the depth of analysis and reporting. Your quotation sets out the scope and price.
How long does an IAQ and BMS data assessment take?
Timing depends on building size, the number of zones and points, data availability and the monitoring period needed. The schedule is set out in your quotation.
