What actually is the standard of building biology measurement technology (SBM 2015)?

We refer again and again - also on our website - to the standard of building biology measurement technology and point out recommendations and guide values. But what exactly is this standard?  
"The Standard of Building Biology Measurement Technology is a red thread, orientation guide and evaluation basis for independent investigations in buildings and on properties." (Institute for Building Biology + Sustainability IBN).  
Building biology has made it its task to recognize biologically critical environmental influences in indoor spaces and, in addition, to minimize and avoid them within the respective individually feasible framework. Thereby, under a holistic consideration of all points from the SBM, a living environment as healthy and unencumbered as possible is to be created. The building biology looks back on a history of 30 years. The first standard was published in 1992 and is now available in its 8th revised version.  

Which risk influences are considered in the SBM? 

The Standard of Building Biology Measurement is divided into three parts and provides an overview of the physical, chemical, biological, indoor climatic and other risk factors.  
The aim is to measure precise and reproducible values with measurements based on natural science and to identify possible risk factors in the living and working environment on this basis.  
After all, people spend 90% of their lives indoors - so it is all the more important to ensure that the environment in these rooms is as healthy as possible. The SBM places a special focus on the sleeping area. In the sleep the body is to regenerate, therefore is here as unloaded an surrounding field as possible completely particularly important. However, all other living areas are also considered holistically and can be evaluated accordingly according to the SBM in its current version.  

The SBM covers the following areas:  

  1. Fields, waves, radiation 
  2. residential toxins, pollutants, indoor climate 
  3. Fungi, bacteria, allergens 

Each sub-area is comprehensively divided into sub-areas and comprehensive guideline values are provided for each area. Thus, under fields, waves, radiation, the following risk factors are considered in detail:  

  • Alternating electric fields (low frequency). 
  • Alternating magnetic fields (low frequency) 
  • Electromagnetic waves (high frequency) 
  • Electric direct fields 
  • Magnetic direct fields 
  • Radioactivity 
  • Geological disturbances 
  • Sound waves 
  • Light 

All other sub-areas are covered just as comprehensively and possible risk factors are illuminated and revealed in detail.

What are the guideline values for high and low frequency electric and magnetic pollution according to SBM?

The SBM provides building biology guide values for sleeping areas according to SBM-2015. These guide values also apply as an extension to sensitive areas such as children's rooms, and to all areas in which a person is exposed to potential harmful influences for more than 4 hours a day.  

The guide values are divided into 4 ranges, which classify the measured values according to their conspicuousness into "none", "weak", "strong" and "extreme" conspicuousness (exact values according to figure).

For all building biology guideline values, the precautionary principle applies first and foremost. As modern people, we live in a modern, highly technical world. "No" abnormality according to SBM is nowadays a practically unattainable condition. At the same time, of course, it is true that every reduction of the existing burden is a step in the right direction. The ideal should always be to aim for the weakest possible exposure - but depending on what steps and measures are individually possible, ANY reduction is worth striving for!  


Building biology, especially building biology measurement technology, has gathered experience in over 30 years with a wide variety of risk factors in the home environment as well as in the workplace. The collected knowledge and measurement results form the basis for the standard of the building biology measurement technique, which serves as a red thread and orientation and, by providing appropriate guide values, makes it possible to find abnormalities in the individual environment and minimize them as far as possible.
