Building Biology

Worried about Sick Building Syndrome and suspect your home or office is making you sick? Unsure where to begin environmental testing or what sort of expert industrial hygienist you need? The Institute for Building Biology and Ecology offers the most comprehensive protocols for building biology assessments and indoor environmental assessments in the United States. There are fewer than 100 practicing Building Biologists providing inspection services in the US.

Healthy Building Science offers unique and comprehensive environmental inspection services that include air testing, mold testingwater testing, and electromagnetic field (EMF) surveys. Building Biologists treat the building as a system and combine expertise from many different disciplines to offer a very thorough environmental assessment. Most Building Biology trainings in the US focus on home inspection techniques, though some US Building Biologists are experienced in all building types.

There are literally thousands of untested chemicals produced in the US everyday. These chemicals infiltrate manufacturing and enter buildings in the form of composite wood, vinyl flooring, adhesive, paints, etc. There are also a number of natural contaminants that can find their way into buildings and negatively affect occupant health. Obvious naturally occurring building pollutants include asbestos and lead, but also bacteria from sewage contamination or mold growth from water damage.

Healthy Building Science is one of the few companies in the US offering Building Biology Surveys as well as Lead Inspections and Asbestos Surveys. The latter both require expert building inspectors to have additional training and certifications.

Building Biology assessments are designed to evaluate more indoor pollutants than any other “healthy building inspection” protocol available in the US. Using this holistic approach, HBS offers a unique glimpse into what exists within the walls of your building, and provides practical suggestions on how to improve your indoor environment. A one-stop-shop for building environmental assessments, HBS targets what counts most.

There are two primary variables in every Building Biology Inspection: Client and Building

After completing a survey about occupants and the building, a Healthy Building Inspector arrives with meters and testing equipment to assess the building. Building upon the pre-inspection survey and a walk-through of the building we make a hypothesis about what pollutants are present and how they may be entering the building.

Environmental testing is sometimes useful to test the hypothesis. Environmental tests performed vary per building, but may include soil testing, air quality testing, water quality testing, and EMF testing.  Your final user-friendly report includes a summary of findings, interpretation of lab results (if any), photos to help illustrate complex building issues, and suggestions for practical steps for mitigation.

Building Biology Case Studies

Success stories from all of our Home Inspection Services can be applied to Building Biology inspections, because Building Biology assessments include almost every measurable indoor pollutant. Using this German-based inspection protocol we have found pollutants, previously unknown to the owner, in every single building we have inspected. When you test for everything you’re bound to find some areas for improvement.

No one rating system can isolate every possible environmental angle, and the International Institute of Building Biology founders were certainly most interested in human health, but it is hard to imagine a more comprehensive healthy building checklist than the Building Biology 25 Principles.

It is quite difficult to incorporate every principle into a single building project, and I would say even more difficult than implementing the Living Building Challenge prerequisites. An astute reader will realize that some Building Biology Principles are the exact opposite of some LEED credits. For instance, LEED promotes developing contaminated sites (aka “brown fields”) in densely populated areas, while Building Biology discourages building on “disturbed” land without “sufficient green space.” To my knowledge, Building Biology has the most human-health focused building design guidelines in the US. The WELL Building Standard is in second place.

For those entrenched green building consultants who only know one rating system… it’s time to branch out and learn about Building Biology Healthy Home Standard, the Green Guide for Health Care (GGHC)GreenPoint Rated, etc.  Each system has its strengths and weaknesses, and a well-rounded consultant should be familiar with all these innovative rating systems. As an industrial hygiene company we are naturally fans of LEED and WELL because they encourage environmental testing to verify performance of indoor environmental quality goals.

The 25 Principles of “Baubiologie” (Building Biology)

  1. Building site without natural and human-made disturbances
  2. Residential homes away from sources of emissions and noise
  3. Low-density housing with sufficient green space
  4. Personalized, natural, human- and family-oriented housing and settlements
  5. Building without causing social burdens
  6. Natural and unadulterated building materials
  7. Natural regulation of indoor air humidity through humidity-buffering materials
  8. Low total moisture content of a new building that dries out quickly
  9. Well-balanced ratio between thermal insulation and heat retention
  10. Optimal air and surface temperatures
  11. Good indoor air quality through natural ventilation
  12. Heating system based on radiant heat
  13. Natural conditions of light, lighting and color
  14. Changing the natural balance of background radiation as little as possible
  15. Without human-made electromagnetic and radio frequency radiation (RFR) exposure
  16. Building materials with low radioactivity levels
  17. Human-oriented noise and vibration protection
  18. With a pleasant or neutral smell and without outgassing toxins
  19. Reduction of fungi, bacteria, dust and allergens as low as possible
  20. Best possible drinking water quality
  21. Causing no environmental problems
  22. Minimizing energy consumption and utilizing as much renewable energy as possible
  23. Building materials preferably from the local region without promoting exploitation of scarce and hazardous resources
  24. Application of physiological and ergonomic findings to interior and furniture design
  25. Consideration of harmonic measures, proportions and shapes

Our Environmental Inspectors Can Check For Most Common Pollutants

Building Biology Assessment

We'll inspect your home or office building and test air, water, soil quality, and electromagnetic frequencies to determine potential safety and environmental issues that may affect occupant health.

Residential inspections start at $595 (Commercial $695) and vary based on the size of the building.

Air Quality & Allergens

Air Quality & Allergens

Visual evaluation of accessible ducts and air filtration, air testing on site (carbon monoxide, combustible gases), and top-to-bottom visual inspection of building for possible sources of indoor air contaminants.

Electromagnetic (EMF) Basic

Electromagnetic (EMF) Basic

Testing for low-frequency electric/magnetic fields and RF radiation on the four corners of the building, plus all sleeping areas. We find all significant sources of EMF exposure and evaluate to determine if utilities are carrying any stray current. Up to 3 hours.

Mold & Moisture

Mold & Moisture

Thorough visual inspection of building from attic to basement, evaluation of site and roof drainage, use of thermal imaging to scan for current moisture issues. Mold lab analysis not included. Confined or contaminated space fee may apply.

Building Biology Environmental Assessment Benefits

Building Biology Environmental Assessments are unlike any other building inspection service found in the United States. If you are uncertain what environmental tests to run, a Building Biology Assessment could be right for you. When a certified Building Biology Environmental Consultant (BBEC) inspects your building you can be confident that they are familiar with indoor pollutants, sampling and testing protocols, and mitigation strategies. Instead of hiring several specialized environmental inspectors, you can rely on a single, highly-qualified, well-trained inspector to evaluate your building from top to bottom.

Common Building Biology testing services include:

  • Air Quality & Allergens
  • Electromagnetic Radiation (EMF, “electro-smog”)
  • Moisture and Mold
  • Soil Testing
  • Water Quality
