Indoor Air Quality and Sick Buildings


The building of man-made structures, from small homes to office towers, projects an appearance of permanence and stability. It indicates a prosperous present, and a commitment to the future. While such structures often appear self-contained and self-sufficient, the reality is far different.

From the day the foundation is laid, the forces of man and nature begin to work on the structure, to adapt to its presence and, ultimately, to tear it down. Wind, rain and sun weaken the materials used to build the structure. Mechanical, electrical, and plumbing systems begin to wear out. Various forms of life, from microbes to small animals, find or create niches in which to live. Dusts, spores, and pollen enter the building through open doors, windows, and building ventilation systems. Coping with these forces requires an extended commitment in terms of building construction and maintenance.

It is well known that any building will begin to decay, if not properly maintained. What is not widely appreciated is the fact that the building will become an unhealthy place in which to live or work, long before the physical signs of wear appear. The process can start with apparently trivial annoyances, as simple as a flickering fluorescent light, or a noisy ventilation system. Other problems may begin to manifest:

These are just a few of the problems that may crop up, and the list is by no means exhaustive. For these reasons, and many others, building occupants may suddenly start to become sick or irritable, for no apparent reason. Sometimes the symptoms become severe, resulting in serious and permanent health effects. Often in such cases, the affected individuals may never safely enter the building again, no matter what remedial measures are taken.

A good building maintenance program can go a long way toward preventing many of these problems. The solution to these problems, once they occur, requires a structured, multi-disciplinary approach. If this is not done, the result can be a scatter-shot attempt at remediation that has no real probability of success.
