These are now widely accepted. S. heating, ventilation, and air-conditioning design firms now use these standards for minimum air design requirements for commercial buildings. Many building codes, such as those designed by municipalities, have officially incorporated ASHRAE 62-1989 into their design standards, thereby making these ventilation standards an enforceable minimum requirement. The ASHRAE design engineers recognize the importance of ventilation control for two reasons: Ventilating air is a means of controlling indoor air contamination through the amount of admission of fresh outdoor air, and control of ventilation has an impact on the energy consumption in the building (see Table 1).
A study by Lippmann (1989) indicates that chronic exposure to ozone may result in accelerated aging of humans. Carbon Dioxide Carbon dioxide is a colorless, odorless gas. It exists in minute quantities in normal air. Indoors it accumulates as humans continuously emit CO2 while breathing. Carbon dioxide is the principal combustion product when burning fuels. Gas, kerosene, and wood-fueled appliances are major sources of CO2. The amount of CO2 accumulating indoors varies considerably. The amount of CO2 normally exhaled by an adult in a room is about 200 milliliters per minute (ml/mn).
Health Effects of Air Pollutants The major reason to measure and control indoor air pollutants is to determine their effect on human health. To acquire this information, it is necessary to measure not only the ambient air concentration of pollutants but also how long the individual has been breathing the pollutant. In addition, how an air pollutant interacts with the human body provides the most useful information about the dose to a target organ or bodily system. The human body has a tremendous capacity to absorb all types of chemicals and either utilize them to support some bodily function or eliminate them, but when the pollutant achieves a level in the body beyond the capacity to remove, then it becomes toxic.
