Indoor Air Quality (IAQ) – One-Page Implementation Checklist

 

A practical IAQ checklist for owners, engineers, consultants, and facility managers

​​

Strategy & Objectives

• Define IAQ objectives (health, compliance, ESG, productivity)

• Identify applicable standards (ASHRAE, WELL, LEED, local codes)

• Align IAQ strategy with Net Zero / Vision 2030 / ESG goals

• Establish performance-based targets (not just prescriptive ventilation)

 

Building & Occupancy Assessment

• Building type (healthcare, hospitality, office, education, mixed-use) Occupancy density and peak usage patterns

• Climate factors (heat, humidity, dust, pollution levels)

• Existing HVAC system type and capacity

• Known IAQ risks (PM, VOCs, pathogens, odours)

 

Technology Selection

1. Select active vs passive purification approach

2. Confirm technology effectiveness across:

• Particulates (PM2.5 / PM10)

• VOCs

• Microbial contaminants

• Odours

• Verify third-party testing and validation

• Ensure ozone compliance and safety thresholds

• Confirm compatibility with existing HVAC systems

 

System Design & Engineering

• Integrate IAQ into HVAC design (not as a bolt-on)

• Confirm correct equipment sizing and placement

• Ensure coverage of occupied breathing zones

• Validate ion / treatment levels against design targets

• Coordinate with ventilation and filtration strategy

 

Measurement & Monitoring

Install real-time IAQ sensors (minimum):

• CO₂

• Temperature

• Relative Humidity

• PM2.5

• TVOCs

​

Define alert thresholds and performance benchmarks
Enable trend logging and historical data storage

Ensure data supports compliance and ESG reporting

 

BMS & Controls Integration

• Integrate IAQ systems with Building Management System (BMS)

• Enable automatic output modulation based on conditions

• Coordinate with ventilation and energy optimisation strategies

• Provide centralised dashboard visibility

 

​Commissioning & Validation

• Verify installation against design intent

• Validate IAQ performance post-installation

• Establish baseline IAQ data

• Document commissioning results

 

Operations & Maintenance

• Define inspection and service intervals

• Confirm consumables and replacement schedules

• Train facilities teams on system operation

• Establish revalidation and performance review process

 

Reporting & Continuous Improvement

• Produce IAQ performance reports

• Align reporting with ESG, WELL, and LEED requirements

• Review data to optimise energy and performance

• Update strategy as building use evolves
