Indoor Air Quality

Indoor air quality (IAQ) is a term which refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants.

IAQ can be affected by gases (including carbon monoxide, radon, volatile organic compounds), particulates, microbial contaminants (mould, bacteria) or any mass or energy stressor that can induce adverse health conditions. Source control, filtration and the use of ventilation to dilute contaminants are the primary methods for improving indoor air quality in most buildings.

Determination of IAQ involves the collection of air samples, monitoring human exposure to pollutants, collection of samples on building surfaces and computer modelling of air flow inside buildings.

Famous quotes containing the words indoor, air and/or quality:

    As a man grows older, his ability to sit still and follow indoor occupations increases. He grows vespertinal in his habits as the evening of life approaches, till at last he comes forth only just before sundown, and gets all the walk that he requires in half an hour.
    Henry David Thoreau (1817–1862)

    To be worst,
    The lowest and most dejected thing of fortune,
    Stands still in esperance, lives not in fear.
    The lamentable change is from the best;
    The worst returns to laughter. Welcome, then,
    Thou unsubstantial air that I embrace!
    The wretch that thou hast blown unto the worst
    Owes nothing to thy blasts.
    William Shakespeare (1564–1616)

    The quality of the will to power is, precisely, growth. Achievement is its cancellation. To be, the will to power must increase with each fulfillment, making the fulfillment only a step to a further one. The vaster the power gained the vaster the appetite for more.
    Ursula K. Le Guin (b. 1929)
