Indoor Environmental Quality (IEQ)

Poor Air Quality, Sick Building Syndromes (SBS) and other building related illness are emerging as critical health, environmental and legal issues throughout the world. Maintaining a healthy and comfortable indoor environment in any building requires integrating many components of a complex system. Indoor environment problems are preventable and solvable and practical guidance on how to manage your building for good indoor environmental quality is available.


Long term exposure to indoor air pollution can cause much more serious health problems. The immediate symptoms can develop over time into respiratory diseases, heart disease, or even cancer. While it is known that airborne pollutants can cause these health problems, it is still unknown how long exposure must be and at what concentration level before serious health problems can arise. The best way to reduce these risks is to reduce the level of indoor air pollutants. Much of the airborne pollutants can be removed with a thorough air duct cleaning.
