How to Maintain Proper Indoor Air Quality
With the continuing effort to clean up oue environment, there is a growing concern with such things as global warming, the ozone hole, the greenhouse effect and Indoor Air Quality (IAQ).

Indoor air pollution is ranked as the highest risk to human health among all types of environmental problems.

While AP has made significant strides to improve IAQ, building occupants still complain of such symptoms as eye irritation, fattigue, headaches and dizzines.

What is indoor air pollution
Acceptable IAQ is "... air in which there are no known contiminants at harmful concentrations as determined by cognizaqnt authorities and with which a substantial majority (80 percent or more) of the people exposed do not express dissatisfaction."

In other words, building owners who monitor the indoor air and remove harmful pollutants will provide a healthy environment for tenants.

Sources contributing to indoor air contimation include ventilation and air conditioning systems, building materials, furnishings, combustion of gases for heating and cooking, smoking cleaning agens and humans.


 

Controlling pollutants with a well ventilated air system.
The most effective method of maintaining the air quality at an acceptable level for optimum human comfort and health is to provide adequate air ventilation throughout the building.

The problem is how to avoid-wasting energy by unnecessarily overventilating a building.

The solution to this problem is found in methods used to control ventilation, such as time-based ventilation or demand-based ventilation with combined CO₂ sensors and mixed gas sensors.
