Ventilation strategies to
improve IAQ in commercial
buildings:
• Increase Ventilation Rates,
based on occupancy or as
prescribed in ASHRAE
Standard 62.1-2022
• Conduct regular inspections,
cleaning, and maintenance
of HVAC systems to ensure
they function efficiently
and deliver clean air. This
includes routine checking
and replacing air filters
when required
• Use mechanical filters such
as ePM2.5 / ePM1 as per
ISO 16890:2016 standards
to capture smaller particles,
including allergens and fine
particulate matter occupancy of different areas • Use commercial-grade air purifiers
• Use occupancy sensors within the building with high-efficiency filters and
to adjust ventilation • Identify and control sources carbon filters to remove airborne
rates based on the actual of indoor pollutants particles and gaseous pollutants
• Maintain optimal indoor humidity
levels (30-50%) to prevent the
growth of mold and dust mites
• Educate building occupants about the
importance of IAQ and encourage
practices that contribute to a healthier
indoor environment, such as proper
waste disposal and not blocking vents
• Conduct regular IAQ assessments,
including real-time monitoring
of pollutant levels and gathering
feedback from occupants
This helps identify areas for
improvement and ensures ongoing IAQ
maintenance
• Implement strict no-smoking policies
within the building to prevent
exposure to second hand smoke, a
significant indoor air pollutant

Tailor the above strategies to suit
the specific characteristics of each
commercial building, including its size,
occupancy, and existing HVAC systems.
Consulting with HVAC professionals and
conducting regular assessments will help
validate the chosen ventilation strategies
in the maintenance of high IAQ. CIJ
