Building biology

Building biology (or Baubiologie) is a field of building science investigating the indoor living environment for a variety of irritants. Practitioners study how the environment of residential, commercial and public buildings can affect the health of the occupants, producing a restful or stressful environment. Important areas of building biology are building materials and processes, electromagnetic fields (EMFs) and radiation (EMR) and indoor air quality (IAQ).^[1]

There are 25 principles of building biology,^[2] which govern the decision making of building biologists.

Effects of poor building

After World War II, new houses were rapidly built in Germany to accommodate the growing population. Studies^[3] of these new houses found an unusual patterns of illnesses. It was concluded that these patterns could be attributed to the rapid construction of the buildings. The rapid construction had given materials insufficient time to outgas various volatile organic compounds (VOCs), and these VOCs instead harmed the occupants. The illness is also attributable to problems with the electrical systems of the homes.

From these discoveries a study^[3][4] began in earnest among a few individuals to catalog and characterize these VOCs. What emerged was a Standard of Baubiologie Method of Testing,^[3] with recommended threshold guidelines for sleeping areas, where one is most susceptible and spends a large amount of time. A small cadre of individuals was formed, and Anton Schneider, Wolfgang Maes and the Institut für Baubiologie und Nachhaltigkeit IBN started a training system in Building Biology. The 'Building-biological Measuring Standard'(see above) relies on physiological impact on biological systems, when determining threshold values. This is in difference to most government standards that use thermal impact (for microwaves) and other quantifiable measures, as advised by the relevant industries. This explains, why the recommended threshold values of the Building-biological Measuring standard are considerably lower than the values advised by government standards.

Helmut Ziehe, Graduate of the original Baubiologie training and Architect, introduced Building Biology to the United States. In 1987, he founded the International Institute of Building Biologie and Ecology (IBE) (http://buildingbiology.net) which presently offers seminars in building biology. Two certification streams are available, the Building Biology and Environmental Consultant (BBEC) and the Building Biology Practitioner (BBP).

Another Graduate of the original Baubiologie training and also Architect, Reinhard Kanuka-Fuchs, introduced Building Biology to New Zealand. In 1990, he founded the Building Biology and Ecology Institute of New Zealand. During the 1990s The New Zealand Institute continued to deliver the original Baubiologie training. In the year 2000, Reinhard passed the directorship of the New Zealand Institute to Alexander Greig. The original training then slowly evolved into an on-line course "Certificate in Ecological Building and Design" This new course was edited and compiled mainly by Jenny Rattenbury.

The three groups of most sensitive individuals that reap the greatest benefits are: Infants, the elderly, and the immuno-compromised.^[1] Some people become environmentally hypersensitive, and although conventional medicine suggests that the problem(s) may be psychological, there is growing acceptance that there is an environmental cause. One aspect of this problem is known as multiple chemical sensitivity (MCS).^[5][6][7]

Criticism

Some practices of building biology conflict with the International Building Code, which is enforced by various government agencies. Some practitioners of building biology argue that lobbying by the insurance, building material and chemical industries keeps unhealthy building practices in legal building.
