Structural Best Practices for Healthy Home

This blog expands on an early post about the 25 Principles of Building Biology and the Healthy Home Standard Checklist. Here we’ll start diving into the Indoor Air Quality Checklist, and focus on structural best practices for healthy home. Like so many things… a solid foundation is so important… and following these best practices for

Antioch College Internship

Healthy Building Science has officially employed two Antioch College students. I did my first “co-op” in 1996 in a peace camp deep in the heart of Chiapas during the Zapatista uprising. Funny how the circle comes all the way around. Dustin Mapel is an Antioch student currently interning with Healthy Building Science. Antioch has long

Carbon Monoxide Facts - CO Kills

Carbon Monoxide Facts Too often we get calls and hear mistruths about carbon monoxide (CO). Here are some carbon monoxide facts and common myths broken down. Carbon Monoxide Myth I can smell carbon monoxide when the furnace is on. Fact CO is actually colorless, tasteless, AND odorless. Because it cannot be noticed without a detector

Healthy Building Checklists

This is the second in a series of blogs diving deeper into the Healthy Building Rating System’s Healthy Home Standard. There are four healthy building checklists within the Healthy Home Standard: Qualification Checklist, Indoor Air Quality Checklist, Electromagnetic Radiation Checklist, and Water Quality Checklist. This blog reviews the first and perhaps most important  of the






EMF and EMR Conversion Formulas

Minimize EMF exposure

How do you convert microwatts per square meter (uW/m2) into microwatts per square centimeter (uW/cm2)?  How many nanoTesla (nT) are in 2.0 milliGauss (mG)?  We’re asked these questions frequently so we’re providing a few common EMF and EMR conversion formulas and conversion charts for your reference. EMF and EMR Allowable Limits “What level of EMF






Mold Testing Petri Dish Impactor

Mold Testing Air Quality Lab Interpretation People with asthma and mold allergies are the first to ask about mold testing. Since their symptoms are primarily respiratory, it is only logical they ask for “air quality testing.” Other individuals looking for peace of mind or suffering much more severe symptoms sometimes also ask for mold testing air

Healthy Building Rating System

Healthy Building Rating System Is there a “Healthy Building Rating System?”  I asked the same question five years ago, when Healthy Building Science was just getting off the ground. Having been a LEED and “green building” consultant for many years, I knew of several health-related credits in the major green building rating systems. The major






Air Quality and Duct Cleaning

NADCA ACR Duct Cleaning Standard

Air quality and duct cleaning are big concerns for some… and big business for others. It seems like every cheap mailer we receive has a scary picture of a rat infested attic and they’re selling duct cleaning services as a way to improve indoor air quality. Is air quality affected by duct cleaning? The simple

Envelope Commissioning Guidelines

Envelope Commissioning Guidelines and Standards include ASHRAE 202P, NIBS Guideline 3, ASTM E2813, and LEEDv4 Enhanced Commissioning credit requirements. The December 2012 issue of Environmental Building News had a great article, Verifying Performance with Building Enclosure Commissioning, that did a great job outlining the differences between traditional mechanical Commissioning (Cx) (HVAC, lighting controls, plumbing, etc) and Building

Building Biology 25 Principles

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 what’s provided in the Building Biology 25 Principles. It is quite difficult to incorporate every principle into
