Indoor Air Quality Monitoring for Offices | 6 Key IAQ Parameters

Indoor air quality monitoring for offices — continuous, real-time tracking of CO₂, PM2.5, TVOC, HCHO, temperature, and humidity with the CU-606 IAQ sensor.

Why Indoor Air Quality Monitoring for Offices

Even in well-ventilated buildings, indoor air quality issues often go unnoticed until discomfort or complaints arise, productivity drops, or compliance questions appear.

Studies conducted in Singapore show that:

• IAQ performance varies across buildings and requires measured data across multiple factors, not assumptions based on ventilation design (PubMed)
• Air-conditioned spaces can experience significant fluctuations in CO₂ and VOC levels depending on usage and occupancy (ScienceDirect)
• Indoor pollutants such as VOCs originate from materials, ventilation systems, and occupant activities (ScienceDirect)

This means that even well-designed buildings do not guarantee consistent air quality.

Without continuous monitoring, these variations remain invisible.

One platform. Six critical IAQ parameters.

The CU-606 monitors the environmental signals that matter most in office spaces:

• CO₂ for ventilation effectiveness and occupancy impact
• PM2.5 for fine particulate exposure
• TVOC for emissions from materials and cleaning agents
• HCHO for formaldehyde monitoring (critical for certifications)
• Temperature for thermal comfort
• Humidity for environmental balance

Singapore standards already define thresholds—for example, CO₂ levels should typically remain below ~1100 ppm for acceptable indoor conditions (National Environment Agency).

The challenge is not defining limits.
The challenge is knowing when and where they are exceeded.

Built for offices and WELL-focused projects

Effective indoor air quality monitoring for offices requires continuous, multi-parameter data rather than periodic checks.

Modern IAQ management requires:

• Continuous monitoring (not periodic checks)
• Multi-parameter visibility (not single sensors)
• Evidence-based reporting (not assumptions)

This solution is designed to support:

• WELL certification strategies
• Office workplace optimisation
• Facilities and operations teams
• ESG and sustainability reporting

What the web portal helps you do

Real-time dashboard visibility

See current IAQ conditions across rooms and zones instantly. Identify issues before they escalate.

Threshold-based alerts

Respond early when CO₂, PM2.5, VOCs, or temperature move outside acceptable ranges.

Historical trends and analytics

Track patterns over time and support audits, reporting, and operational improvements.

Multi-site management

Monitor multiple offices from a single platform and standardise IAQ visibility.

Actionable reporting

Convert sensor data into clear insights for both technical teams and management.

Why monitoring is needed — even in good buildings

Singapore-based studies consistently show a clear pattern:

1. Average conditions may look acceptable

Many buildings meet general IAQ guidelines most of the time (A comparative study of VOCs in Singapore and European office buildings from ScienceDirect)

2. But fluctuations are common

CO₂ and VOC levels can spike significantly in enclosed or occupied spaces (Assessment of indoor air quality in air-conditioned small business units with no mechanical ventilation from ScienceDirect)

3. Sources are dynamic

Pollutants come from real-world usage:

• Occupancy density
• Materials and furnishings
• Cleaning and daily operations (ScienceDirect)

4. Impact is measurable

Local studies show improving IAQ (e.g. reducing VOCs) can improve cognitive performance by ~12% (Corporate NTU)

The implication

The risk is not “bad buildings.”

The real issue is:

Invisible variation in air quality that is not actively monitored or managed.

Why customers choose this solution

1. Clear visibility, not assumptions

Replace periodic checks with continuous monitoring.

2. Multi-parameter coverage

CO₂ alone is not enough—real IAQ requires multiple data points.

3. Designed for real operations

Dashboards, alerts, and trends support daily facility management. Other benefits include energy consumption reduction.

4. Scalable deployment

LoRaWAN connectivity enables cost-effective monitoring across multiple zones and sites.

5. Evidence for compliance and reporting

Supports WELL-related documentation and internal reporting needs.

Ideal applications

• Corporate offices
• Meeting rooms and enclosed spaces
• Open-plan workplaces
• Renovation and fit-out monitoring
• Schools, clinics, shared facilities
• WELL and green building projects

How it works

Step 1: Deploy CU-606 sensors

Install in key indoor zones.

Step 2: Connect to the platform

Data is transmitted for centralised monitoring.

Step 3: Monitor, alert, improve

Identify issues early and respond with confidence.

Use cases that matter

Meeting rooms with rising CO₂

Occupancy-driven spikes can occur quickly—even in well-ventilated buildings.

Fit-outs and renovations

VOC and formaldehyde emissions can increase after new materials are introduced.

Multi-zone offices

Different areas behave differently—averages hide real issues.

WELL-related monitoring

Continuous data supports certification and reporting requirements.
