firefox-grayDavid Eyer pofessionally started baubiology in 2002. He graduated at Baubiology institute in Neubeuern (IBN). In 2002 he became partner of akad. arch. Oldrich Hozman in Studio ARC, where he designed construction according to baubiology rules. This experience had enormous influence to his architectural approach. He cooperates with JAMIprojekt on his current projects. He is also project manager in MAITREA a.s., where he is responsible for building Waldorf Kindergarten near Prague, reconstruction of  a 100 year old office building, vegetarian restaurant in Prague centre and building a school for martial arts. Occasionally he publishes and give lectures on baubiology. He is member of Czech association Ecohouse and INTBAU Czechia.

What is Bau-Biologie?

Bau-Biologie is the science of the holistic relationship between life, the living environment and the built environment. Nature is the ultimate guide.

Have you ever spent time in a building that embraced and nurtured you…body and soul, one that awakened and delighted your senses? Imagine being in a forest, near a gently flowing clear mountain stream. The sun is shining and its rays warm your face. A fragrant breeze lightly brushes your skin as your footsteps trod upon the soft loam of the earth beneath your feet. You can experience these sensations once again when you enter your own home, provided your home has been built in accordance with the laws of nature. In order for us to be truly natural and healthy, our homes need to supply us with adequate opportunity to rest and relax, they need to nurture, as it is only through that, that we can truly recuperate at the end of the day and recharge with the strength to deal with the next day’s emotional and physical stresses. Bau-Biologie® is the holistic study of the man-made environment, human health and ecology. The intrinsic aspect of IBE is to hold Nature as the golden principle. Bau-Biologie®, or Building Biology, is not a narrowly specialized subject, but is a living subject that brings together fields of study that are otherwise only taught in isolation. Bau-Biologie was founded in Germany by a group of professionals from a variety of disciplines concerned about the inability of post-war housing to support health and ecology. IBE was started in North America in 1987, with a mission to raise awareness that buildings can abide by the laws of nature.

Materials that are not natural don’t resonate with us, and therefore don’t nourish us – they deplete us. Nature is our ultimate guide.

There is an international movement of individuals who are concerned with the environmental factors of the built environment that affect human health. This group is involved with delivering current information regarding environmentally-friendly building systems and materials. This group is the International Institute for Bau-Biologie® and Ecology (IBE).


Goal of Bau-Biologie

The German term “Bau-Biologie” means “building biology” or “building for life.”

Building Ecology can be defined as the relationship between the building and the environment.

The phrase “Bau-Biologie® and Ecology” specifically refers to the study of

  • the impact of the built environment on human health, and the application of this knowledge to the construction of natural homes and workplaces; and
  • the holistic interaction of human involvement with the environment and the regenerative sustainability of the environment.

The underlying principle is one of “balance.” All materials that come from the natural environment make up the “living structure” and will promote health. When these materials are returned to the natural environment they will cause no harm. Problems occur for people and the environment when synthetic materials and man-made pollutants are introduced.

IBE is in support of “Green Programs” as they promote the removal of all pollutants from the built environment. The IBE Principle sets a new vision of going beyond green by going beyond the standard material, methods and construction practices. The IBE Principle vision integrates ecology and biology with allied health practices. The engineering and energy conservation techniques are combined with the economics of each of these decisions resulting in a sustainability which is healthier for the occupant and the planet.

The IBE mission brings together design methods and technology to provide the information needed to create healthy homes and workplaces. This knowledge will raise awareness, provide tools for solutions, and promote effective ecological practices for our future generations.


Historical Data

While the phrase “Bau-Biologie and Ecology” is relatively new, the science is not. There have been many pioneers – in the United States, Canada, Germany, and throughout the world – who have studied and written about various aspects of building technology and effects on human health. A few of these forerunners include human ecologist Theron G. Randolph, M.D., Wilhem Reich, architect Richard Crowther, and writer Ken Kern (author of The Owner-Built Home) were driving forces in the United States. Hubert Palm, M.D., wood technologist Anton Schneider, Ph.D., and electro biologist Alfred Hornig helped to establish the Bau-Biological movement in Germany. The work of Nikola Tesla, electrical engineer/inventor, was also of significance to the movement.


25 Principles of Bau-Biologie

The following list of twenty-five principles were developed by Anton Schneider, Ph.D., founder of the Institut fűr Baubiologie and Oekologie. These principles can be used while planning the construction of a natural and ecologically friendly home, or while remodeling an existing one.


  1. Make sure the building site is geologically undisturbed.
  2. Place dwellings away from industrial centers and major traffic roads.
  3. Place dwellings well apart from each other in spaciously planned developments amidst green areas.
  4. Plan homes and developments individually taking into consideration the human aspect and the needs of family life and nature.
  5. Use natural and unadulterated building materials.
  6. Use wall, floor and ceiling materials, which allow the diffusion of moisture.
  7. Allow natural self-regulation of indoor air humidity using hygroscopic materials.
  8. Consider sorption of building materials and plants (in- and outside), which allow filtration and neutralization of toxic airborne substances.
  9. Design for a balance between heat storage and thermal insulation in living spaces.
  10. Plan for optimal surface and air temperature.
  11. Use thermal radiation for heating buildings employing solar energy as much as possible.
  12. Promote low humidity and rapid desiccation in new buildings.
  13. Utilize building materials, which have neutral or pleasant natural scents and which do not emit toxic vapors.
  14. Provide for natural light and use illumination and color in accordance with nature.
  15. Provide adequate protection from noise and infrasonic vibration or sound conducted through solids.
  16. Use building materials that do not have elevated radioactivity levels.
  17. Preserve the natural (DC) air electrical field and physiologically beneficial ion balance in space.
  18. Preserve the natural (DC) magnetic field.
  19. Minimize technical (AC) electric and (AC) magnetic fields.
  20. Minimize the alteration of vital cosmic and terrestrial radiation.
  21. Utilize physiological knowledge in furniture and space design.
  22. Consider proportion, harmonic orders, and shapes in design.
  23. Use building materials that do not contribute to environmental problems and high energy cost in the production process.
  24. Do not support products or building materials that over-use limited and irreplaceable raw materials.
  25. Support building activities and production of materials which do not have adverse side-effects of any kind and which promote health and social well-being.


Planning and Design Criteria of Bau-Biologie

During the planning and design states of building a biological home, the following eight additional criteria should be considered:

1. Selection of proper site, including the analysis of the soil and geophysical conditions. Consider climatic factors, which would include prevailing winds, temperature, solar orientation, relative humidity and rain fall.

2.Selection of proper building materials, both structural and finishing that enhance the ability of the structure to “breathe.” Select natural building materials that allow for self-regulating interior relative humidity that accomplish this task utilizing hygroscopics. Consider using building and plant materials on both the interior and exterior that exhibit sorption and the filtering and neutralizing of toxic airborne substances.

3. Make careful decisions about energy; consider the use of solar energy, the methods of heat and energy conservation, and the use of thermal insulation. Design for a balance between heat storage and thermal insulation in living spaces that utilize radiant rather than convection heat distribution.

4. Select appropriate ventilation, water and air filtration systems to establish a healthful living environment. An efficient artificial ventilation system can be used to supplement the natural ventilation of a home. Water systems should be ecological and also non harmful to occupants.

5. Take care to select the right illumination (light temperature, spectral range, intensity, etc.) for each room. This factor is as important for your well-being as shielding unwanted noise.

6. Avoid electromagnetic fields, especially in areas of the house where people spend lots of time (bedroom, play and work areas).

7. When doing the interior design, use furniture that is in proper proportion to the residents; use materials that do not outgas and create static electricity.

By applying the twenty-five Bau-Biologie Principles and seven Planning and Design Criteria, not only should the most obvious mistakes in modern building construction be avoided but a home with living qualities far superior to those of the average home today should result. Experience by both architects and laypersons here and abroad, have created a fine variety of healthy, energy-efficient homes.
