Management of IAQA Coordinated Effort
IAQ Basics
  • Problems occur in many types of buildings
  • Problems reflect both comfort and health related
  • Primary sources of IAQ problems include
  • Ventilation
  • Contaminants generated indoors
  • Infiltration of outdoor contaminants
  • Unidentified sources

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 lt1
    micrometers (µm) (welding)
  • Dust Particulate ranging in size from 0.1 to
  • Fibers An elongated particle with aspect ratio
    of greater than 31
  • Bioaerosols Airborne particles that originate
    from living organisms (i.e., pollen, spores,
    fragments, waste)

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 concentrations as determined by
    authorities and at which a substantial majority
    (80 or more) of the people exposed do not
    express dissatisfaction

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

Sick Building Syndrome (SBS) vs.
Building-Related Illness (BRI)
  • SBS
  • Symptoms
  • Do not fit the pattern of any particular illness
  • Difficult to trace to a specific source
  • Relief occurs upon leaving the building
  • BRI
  • Symptoms
  • Are often accompanied by physical signs
    identified by a physician and/or laboratory
  • Relief from illness may not occur upon leaving
    the building

Sick Building Syndrome (SBS) vs. Building-Related
Illness (BRI)
  • SBS
  • Symptoms
  • Headaches
  • Eye, nose, throat irritation
  • Dry or itchy skin
  • Fatigue
  • Dizziness
  • Nausea
  • Loss of concentration
  • BRI
  • Symptoms
  • Eye, nose, throat, and upper respiratory tract
  • Skin irritation or rashes
  • Chills, fever, cough, chest tightness,
    congestion, sneezing, runny nose
  • Muscle aches

Building-Related Illnesses
  • Hypersensitivity Pneumonitis
  • Asthma
  • Chemical Sensitivity
  • Legionnaires Disease

IAQ Basics
  • Factors Affecting IAQ
  • Building occupant activities
  • Design and condition of HVAC
  • Construction and renovation activities
  • General outdoor sources

IAQVentilation System
  • Heating Ventilation and Air Conditioning (HVAC)
  • Purpose
  • Regulates the temperature and humidity for
  • Supplies general ventilation to decrease indoor

IAQBasic Ventilation System
IAQComplex Ventilation System
IAQVentilation System
IAQVentilation System
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

IAQVentilation System
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

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

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
  • No exhaust should be released into the plenum
  • Prevent contamination of the area and ensure air
    flow is not blocked

IAQVentilation System
  • Ducts
  • Move the filtered and conditioned air to occupied
    areas of the building

IAQVentilation System
  • Fans
  • Ensure fan belts are operating properly
  • Rotation

IAQVentilation System
  • Local Exhaust System
  • Buildings should remain under slightly positive
    pressure to avoid bringing in unfiltered air

IAQVentilation System
  • Dampers
  • Check condition of dampers and controls
  • Ensure dampers are operable and meet the design
    specifications for bringing in outdoor air
  • Clean screens and grilles and prevent
    obstructions in this area

IAQ BasicsBuilding Conditions and Effects
  • Problem Poorly regulated temperature and
    humidity levels
  • Effects

  • Temperature extremes
  • Solutions
  • Ensure sizing of HVAC system
  • Balancing
  • Inspect for blocked supply diffusers

IAQ BasicsBuilding Conditions and Effects
  • Problem Lack of Fresh Air
  • Effects
