Alex Stadtner, BBECHealthy Building Science provides Building Biology and green building consulting services for new and existing buildings. We are headquartered in the San Francisco Bay Area and serve clients around the US.

New Construction or Renovation: Our services are for those just starting to go "green," or those teams ready to push the sustainability envelope. Occupant health is our top priority. We add value and implement the principles of Building Biology to projects of every size.


  • Facilitate Eco-Charrette (early design visioning meeting)
  • Site Assessments
  • Design Reviews
  • Specification Reviews & Materials Research
  • Project Management for rating systems (e.g., Building Biology, LEED, Green Guide for Health Care, etc.)
  • Contractor Trainings (e.g., Waste Management Plans, IAQ protocols, etc.)

Existing Building Inspections: We provide Building Biology Inspections for existing residential and commercial buildings. Our healthy building inspections are for renters, managers, owners, and those about to sign a lease or purchase property. Through the use of sensitive meters and careful lab analysis, we find invisible and odorless pollutants and provide user-friendly reports suggesting mitigation strategies.

  • Air Quality (allergens, particulates, gases, VOCs)
  • Moisture and Mold Inspections (viable and non-viable, mold clearance testing)
  • Soil Sampling
  • Water Quality (bacteria, chlorinated compounds, heavy metals, PCBs, etc.)
  • Electromagnetic radiation (extremely low frequency electric & magnetic fields, radio frequency)

Additional services available on request. Contract and hourly services available.
