4 Ventilation Quotes That Will Rock Your IAQ World
I've been writing some articles on ventilation for the Journal of Light Construction lately and have come across some great material. The first quote here makes the point about indoor air quality with a graphic underwear metaphor. It's from an 1893 book whose author was a medical doctor interested in ventilation to prevent diseases like phthisis (what we now call tuberculosis).
Most civilized men and women are unwilling to put on underclothing that has just been taken off by another person or to put into their mouths articles of food or drink that have recently been in other peoples mouths but they take without hesitation into their lungs air that has just come from other people's mouths and lungs or from close contact with their soiled clothing or bodies.
~ John Shaw Billings, Ventilation and Heating, 1893
The second is from a great article called The History of Ventilation and Temperature Control (pdf) that appeared in the ASHRAE Journal in 1999. The author was discussing some of the mid-twentieth century research on odor and ventilation rates by Harvard scientist C.P. Yaglou. If you're worried about the water-energy connection, you'll be happy to know that:
Only a 33% increase in ventilation was required for adults a week after a bath.
~ John Janssen, in The History of Ventilation and Temperature Control, ASHRAE Journal, 1999
Naturally, ventilation cannot solve all IAQ problems. Sometimes source control is the best method.
If there is a pile of manure in a space, do not try to remove the odor by ventilation.
Remove the pile of manure.
~Max von Pettenkofer, 1858
And finally, no list of ventilation quotes is complete without one that illustrates the immense power of fresh air.
There is nothing like the cure of fresh air for cases of bladder infection, paranoia, and Cartesian thinking.
~ Rawi Hage
