    Study Notes

    Environmental Protection Agency (EPA)

    • Established in December 1970 by Richard Nixon.
    • Oversees indoor air quality.

    Legionnaire's Disease

    • Serious pneumonia caused by Legionella bacteria.
    • Transmitted by inhaling contaminated water droplets/aerosols.
    • Example: Spread from cooling towers in a hotel.
    • Legionella found in water systems, hot tubs, etc.

    ASHRAE Standard 62.1

    • Covers indoor air quality in all occupied spaces (except low-rise residential).
    • Sets ventilation rates based on space type, occupancy, and activities.
    • Doesn't specify all contaminant limits; references EPA and OSHA standards.
    • Addresses VOCs via relevant health guidelines.
    • No direct ACH (air changes per hour) prescription; ventilation rates are translated to ACH.
    • Recommended relative humidity (RH): 30-60%.
    • Minimum MERV for filters: 6-8.
    • Natural ventilation: Openable areas (windows) should be at least 4% of net floor area.

    ASHRAE Standard 62.2

    • Focuses on low-rise residential buildings (single-family, duplexes, up to 3 stories).
    • Defines minimum ventilation rates for acceptable indoor air quality.
    • Example calculation: Qtotal = 0.03 × Afloor + 7.5 × (Nbr + 1).
    • Qtotal = total ventilation rate (CFM)
    • Afloor = floor area (sq ft)
    • Nbr = number of bedrooms
    • Minimum kitchen exhaust: 100 CFM intermittent or 5 ACH continuous.
    • Minimum bathroom exhaust: 50 CFM intermittent or 20 CFM continuous.
    • Minimum MERV for filters: 6 or higher.
    • Discourages unvented combustion appliances (must meet strict emissions).

    Indoor Air Quality (IAQ) Investigations

    • Office Conditions: Housekeeping practices, vacuuming frequency, carpeting/drape cleaning, waxing, dust levels, pesticides, moisture intrusion.
    • Air Quality Characteristics: Odor, dryness, humidity, dust, temperature fluctuations (between offices, floors).
    • Recent Changes: Workspace alterations, office changes, building changes.
