iaq basics
IAQ Basics
  • Problems occur in many types of buildings
  • Problems reflect both comfort and health related issues
  • Primary sources of IAQ problems include:
    • Ventilation
    • Contaminants generated indoors
    • Infiltration of outdoor contaminants
    • Unidentified sources
iaq basics1
IAQ Basics
  • Types of Air Contaminants
    • Vapors – Solid or liquid converted by heat to a gaseous state (i.e., methylene chloride, mercury)
    • Gases – Formless fluid occupying an enclosure which confines it (i.e., carbon dioxide, oxygen)
    • Fumes – Condensation of gas into particle <1 micrometers (µm) (welding)
    • Dust – Particulate ranging in size from 0.1 to 25µm
    • Fibers – An elongated particle with aspect ratio of greater than 3:1
    • Bioaerosols – Airborne particles that originate from living organisms (i.e., pollen, spores, fragments, waste)
acceptable iaq
Acceptable IAQ

American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE) defines acceptable IAQ as:

“air in which there are no known contaminants at harmful concentrationsas determined by authorities and at which a substantial majority (80% or more) of the people exposed do not express dissatisfaction”

iaq basics2
IAQ Basics
  • Health Effects
    • Varied and non-specific
    • Reports of health related problems and comfort issues
    • Air monitoring does not always support their existence

    • General outdoor sources
iaq ventilation system
IAQVentilation System
  • Heating Ventilation and Air Conditioning (HVAC)
    • Purpose
      • Regulates the temperature and humidity for comfort
      • Supplies general ventilation to decrease indoor pollutants
iaq ventilation system3
IAQVentilation System
  • Air Handling Unit (AHU)
    • Air Filters
      • Air filters should have a dust-spot rating between 35% and 80% or a Minimum Efficiency Rating Value (MERV) of between 8 and 13
      • Some filters are not efficient enough to remove small fungal and bacterial spores
iaq ventilation system5
IAQVentilation System
  • Air Handling Unit (AHU)
    • Humidification and Dehumidification
      • Humidification provides moisture to the air and dehumidification removes the moisture
      • Maintain relative humidity below 60% in all occupied spaces and in low air-velocity plenums
iaq ventilation system6
IAQVentilation System
  • Air Handling Unit (AHU)
    • Coils and Drain Pans
      • Coils dehumidify the air forming condensate water which is released into drain pans and removed from the AHU
iaq ventilation system7
IAQVentilation System
  • Air Handling Unit (AHU)
    • Return Air Plenum - Space above ceiling tiles is often used as return air plenum
      • Maintain all exhaust systems that pass through plenum
      • No exhaust should be released into the plenum
      • Prevent contamination of the area and ensure air flow is not blocked
iaq ventilation system8
IAQVentilation System
  • Ducts
    • Move the filtered and conditioned air to occupied areas of the building
