Today we are exposed to a cocktail of toxic chemicals—not only at home. To build, renovate, and live in a healthy manner, sound knowledge is essential. And to avoid adverse health effects and environmental destruction from air pollutants, they must be identified, verified, and properly removed or at least reduced to a tolerable level. The Building Biology Testing Methods provide the necessary know-how.

Again and again some building biology professionals and articles in the literature seem to convey the impression that building biology would be exclusively about avoiding electromagnetic pollution as well as air pollutants harmful to health and the environment. As important as these subject areas are, healthy and sustainable building, renovating, and living clearly involves many more subject areas—see all other course modules as well as The 25 Principles of Building Biology.
