Pensive About Process

Posted on March 4, 2009 by Ann Edminster, GBA Advisor in Building Science

In the green-building community, we talk a lot about how essential an integrated design process is to achieving a really green project. I’ve been thinking about that more and more over the last two years, ever since after I retired from chairing the USGBC’s LEED for Homes development effort.

Scammers continue to use exaggerated R-valueMeasure of resistance to heat flow; the higher the R-value, the lower the heat loss. The inverse of U-factor. claims to peddle inferior insulation products, in spite of the existence of strong consumer protection laws. Year after year, naïve builders fall prey to Web-based marketing pitches for “miracle” products like “insulating” paint and 1-inch-thick R-10 foam.

Cleaner and More Efficient Wood Burning

Posted on March 3, 2009 by Alex Wilson in Energy Solutions

Wood is a renewable fuel and, assuming that new trees grow up to replace those cut for firewood, it is carbon-neutral, meaning that it doesn’t have a net contribution to global warming. That said, wood burning also churns out a lot of air pollutants, some of which are highly visible as smoke. Fortunately, there’s a lot we can do to reduce the pollution generated by wood burning—and boost the efficiency.

Tools of the Trade: Moisture Meters

Posted on March 2, 2009 by Peter Yost in Building Science

A moisture meter is a simple, easy-to-use tool for evaluating moisture and mold problems

Moisture meters help you figure out whether your building materials are too wet. They typically use electrical conductivity between a couple of metal pins to assess moisture content; the more moisture in the material, the greater the electrical conductivity. The moisture content is measured as a percentage of total weight.

When You Come to a Fork in the Code, Take It

Posted on March 2, 2009 by Lynn Underwood, GBA Advisor in Code Green

Building codes are ambitious documents that do a lot while offering flexibility in how they’re satisfied.

“The purpose of this code is to provide minimum requirements to safeguard the public safety, health and general welfare through affordability, structural strength, means of egress facilities, stability, sanitation, light and ventilation, energy conservation and safety to life and property from fire and other hazards attributed to the built environment.”

E-Myth Revisited cover

A book every green builder needs to have on the shelf

Posted on March 2, 2009 by Michael Chandler, GBA Advisor in Business Advisor

It took me 20 years to get my business running smoothly. Books like this have helped a lot.

There are a small number of books that have been so important to me that I buy them in quantity to give to friends. To new parents I give Kids Are Worth It by Barbara Coloroso, and to new employess, How to Win Friends and Influence People by Dale Carnegie. Among the books I give to my fellow green builders is The E-Myth Revisited by Michael Gerber.
