Indoor Air Pollution

@ About.com |
In the early and mid 1900's, building ventilation standards called for
approximately 15 cubic feet per minute (cfm) of outside air for each building occupant,
primarily to dilute and remove body odors. As a result of the 1973 oil embargo, however,
national energy conservation measures called for a reduction in the amount of outdoor air
provided for ventilation to 5 cfm per occupant. |
