Building Biology Standard (SBM)
The first ever precautionary exposure guideline for sleeping areas has been developed by Baubiologie Maes with the support of the Institute of Building Biology + Sustainability IBN and in cooperation with many medical doctors, scientists, and environmental experts. With its holistic approach, the Building Biology Standard (SBM) covers physical, chemical, and biological pollutants, ranging from electromagnetic fields, radiation, noise, and light to toxic chemicals, gases, molds, yeasts, and allergens.
Unlike regulatory exposure limits, which are designed to protect against harmful short-term effects, the SBM guidelines are specifically designed to help measure, assess, and remediate long-term exposure in the sleep environment. The precautionary guideline values are based on scientific evidence, empirical observations, and building biology knowledge to promote healthy sleep. The first Building Biology Standard (SBM) was published in 1992 after thousands of building biology assessments of bedrooms were completed.

“Any risk reduction is worth it.
Guideline values are meant as a guide.
Nature is the ultimate standard.”

SBM exposure guideline values
for sleeping areas
The SBM exposure guidelines have
four categories for evaluation.
No anomaly
No action required.
Slight anomaly
Take preventive action.
People with sensitivities and chronic conditions are well advised to take extra care and precautions.
This range reflects natural conditions or the unavoidable modern background level.
Severe anomaly
Take action.
Case histories and scientific studies indicate biological effects and health problems.
Extreme anomaly
Take immediate action.
International guidelines and recommendations may be reached or even exceeded.
