It is time we move away from ventilation designed for merely acceptable indoor air quality
and move towards design for optimal indoor air quality.
ASHRAE (2013) defines acceptable indoor air quality
as "air in which there are no known contaminants at harmful concentrations as determined by cognizant authorities and with which a substantial majority (80% or more) of the people exposed do not express dissatisfaction".

He concluded, "Utilizing the most suitable and energy efficient units is vital for maintaining and improving acceptable indoor air quality
, heat and cooling conditions while lowering utility expenses for small, medium and large buildings.
In Texas, no designated or funded "Indoor Air Quality Program" exists to encourage the use of ASHRAE guidelines or to provide other direct assistance to schools to ensure acceptable indoor air quality
for their students.
American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE), Ventilation for acceptable indoor air quality
4) The American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) has been the lead professional organization for developing and recommending ventilation standards and guidelines for acceptable indoor air quality
in North America.
With respect to indoor air quality in general, the American Society of Heating, Refrigerating and Air Conditioning Engineers developed standards in 1989 addressing ventilation, resource management and air cleaning that were intended to be used to achieve an acceptable indoor air quality
To ensure acceptable indoor air quality
, the sidestream smoke of one cigarette would have to be diluted by an estimated fresh air volume of 19,000 cubic meters.
Combine these enhancements with great filtration, a custom-formed airflow hood and the unique coanda air flow pattern and you have a unit capable of achieving acceptable indoor air quality
Cumulative test results indicated that no additional means were necessary to tighten the envelope, nor were additional provisions necessary to provide ventilation for acceptable indoor air quality
Ventilation is part of the acceptable indoor air quality
and thermal comfort problem.
