Nanotechnology and Coatings
Wednesday, 27 November 2013
In helping our clients choose healthy building materials, I tend to be weary of coatings in general, but nanocoatings are of particular concern. In building materials, manufacturers advertise nanocoatings on carpets, upholstery, photovoltaics, and even toilets. I’ve seen these coatings used as stain repellants, waterproofing coatings or as finishes that create a smooth and easily

Does Stainless Steel Leach Chemicals? There is a lot of information in the blogosphere about health and safety in cookware, but when a client asked whether stainless steel leached dangerous chemicals, I was unable to find a quick answer to her question.

Magnetic Fields – EMF Consulting
Wednesday, 23 October 2013
When performing EMF surveys many “EMF consultants” only evaluate low-frequency magnetic fields. When folks call and say they “have an EMF meter” and are measuring “high emf,” they generally have a Gauss meter and are measuring magnetic field field strength or magnetic flux. Most Building Biologists focus on Alternating Current (AC) electromagnetic fields, and in addition

When most people build or remodel their homes, they pay close attention to indoor air quality, comfort and aesthetics. The task of building to survive natural disasters like earthquakes (as the San Francisco Bay region is prone to) is left to building codes and local code enforcement. And the task of ensuring the home maintains livable

EMI and LEDs – Not all LEDs are the same!
Tuesday, 10 September 2013
EMI and LEDs – Not all LEDs are the same! Electromagnetic Interference (EMI, aka: “Dirty Electricity,” or “High Voltage Transients”) is a term coined for quick transient pulses, harmonics, spikes and dips in the electrical power in a home’s wiring that deviates from a purely 60Hz sine wave. These often occur due to computers, other
Blown-in-Cellulose Insulation
Wednesday, 21 August 2013
Blown-in-Cellulose Insulation Test Results On a recent project, we recommended a homeowner try Blown-in-Cellulose insulation as a healthy alternative to other insulation choices. Blown-in-cellulose is known in the healthy materials world as a pretty safe insulation choice. But just to be sure the product was safe, we sent a wet sample to a lab for
EMF at High Performance Schools
Monday, 05 August 2013
Do you want to send your kids to an EMF hot-spot with unknown health ramifications? Are some existing symptoms a result of EMF? Reducing exposure to Electromagnetic Fields or Radiation (EMF or EMR) is a contentious debate in public health and green building circles across the United States. OSHA does provide rather liberal exposure limits for
