Building Biology Advocate™ (BBA)

Nature is the Gold Standard

Designed for environmentally conscious people from all walks of life, Building Biology Advocate (BBA) certification will give you the knowledge and skills with which to improve the health-supporting essence of your own dwellings and workplaces, and educate others in this increasingly vital area of public health and well-being. BBA certification is also ideal for students and industry professionals who are seeking to complement their credentials in such fields as architecture, city planning, green building, interior and landscape design, Feng Shui, natural health, and the practice of medicine.

Please note that Building Biology Advocates (BBAs) are certified in Building Biology theory, but are not certified to assess, identify, and/or mitigate indoor environmental hazards to human health. Prior alumni of this program are Building Biology Practitioners (BBP), and they are subject to the same limitations stated as our BBAs are, here above.
