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 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 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 issues Air monitoring does not always support their existence
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 findings 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 irritation 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
IAQ Ventilation System Heating Ventilation and Air Conditioning (HVAC) Purpose Regulates the temperature and humidity for comfort Supplies general ventilation to decrease indoor pollutants
IAQ Basic Ventilation System
IAQ Complex Ventilation System
IAQ Ventilation 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 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 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 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 System Ducts Move the filtered and conditioned air to occupied areas of the building
IAQ Ventilation System Fans Ensure fan belts are operating properly Rotation
IAQ Ventilation System Local Exhaust System Buildings should remain under slightly positive pressure to avoid bringing in unfiltered air
IAQ Ventilation 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 Basics Building Conditions and Effects Problem: Poorly regulated temperature and humidity levels Effects: Temperature complaints Condensation, microbial contamination Dryness, upper respiratory irritation, nosebleeds Solutions: Check system sizing Adjust dampers Location of controls
IAQ Basics Building Conditions and Effects Problem: Disruption of air circulation Effects: Stagnant air Temperature extremes Solutions: Ensure sizing of HVAC system Balancing Inspect for blocked supply diffusers
IAQ Basics Building Conditions and Effects Problem: Lack of Fresh Air Effects: Stagnant air Odors Increased contaminant concentrations Solutions: Develop and follow preventive maintenance schedule Ensure dampers are open and operational Inspect filters for condition and compatibility
