Building Biology Evaluation Guidelines.
The Institute of Building Biology and Sustainability (IBN) offers evaluation and testing guidelines for a comprehensive list of indoor environment criteria.
The following areas of consideration are considered:
Fields, waves, and radiation Includes guidelines for AC electric fields, AC magnetic fields, radio-frequency radiation, static electric fields, static magnetic fields, radioactivity, geological disturbances, sound waves, and light.
Indoor toxins, pollutants, and indoor climate Includes guidelines for formaldehyde, solvents, pesticides, heavy metals, particles and fibers, and indoor climate (temperature, humidity, CO2, air ions, air changes, and odors).
Fungi, bacteria, and allergens Includes guidelines for molds, yeasts, bacteria, dust mites, and other allergens.

The evaluation is not rated by points or pass/ fail, but uses four categories to characterize each individual criteria examined:
No anomaly Reflects natural conditions.
Slight anomaly Precautionary remediation recommended.
Severe anomaly Conditions not acceptable by Building Biology standards; biological and health problems are likely if not remediated.
Extreme anomaly International guidelines are exceeded; biological and health problems are very likely if not remediated.
