I’ve worked the last 25 years on developing parts of what is now called “Eco-design,” under the belief that healthier buildings, lower energy use, and less ecological impact were important. This was only to discover recently that all this time I was still looking at things in isolation rather in their ecological interconnectedness!

A one-square-foot sample of low-e glazing, representing the one billionth square foot produced, was recently presented to Christine Ervin, Assistant Secretary of the U.S. Department of Energy by Mike Koenig of Andersen Windows and Jim Larsen of Cardinal IG. The presentation was in recognition of ongoing support provided by DOE of window... Read more

Schuller Corporation, a publicly traded manufacturer of fiberglass insulation based in Denver, Colorado, announced on May 17 that it is acquiring NRG Barriers of Portland, Maine, one of the nation’s leading producers of polyisocyanurate foam insulation. Both Schuller and NRG have been leaders in improving the environmental characteristics of... Read more

Nuclear proponents have often pointed to the low electricity prices in France as evidence that high reliance on nuclear power keeps electricity prices low. But by comparing

pre-tax electricity rates, that claim is dispelled. According to the May/June issue of

World Watch Magazine, the three European countries with the lowest pre... Read more

Expanded polystyrene (EPS) manufacturers representing 70% of the EPS industry recently joined together in April 1995 to form a trade organization, the EPS Molders Association, to more effectively promote their products. According to the May 1996 issue of

Energy Design Update, this development should help solve one of the biggest... Read more

The pilot lights on gas-fired fireplaces waste a lot of energy. That’s one conclusion of a recent study by Skip Hayden of the Combustion Gas Research Laboratory of CANMET and Consumers Gas, a major Canadian gas utility. Fifty-two homes with significant use of gas fireplaces were surveyed; 38 of these had continuous pilots. In the homes with... Read more

A newly formed organization is now developing standardized testing protocols for indoor air quality related products and materials. The Product Emissions Testing Lab (PETL) Network is bringing together representatives of academia, government, and industry to achieve consensus-based procedures and to certify laboratories to test products...

Congratulations on an excellent May/June 1996 issue! Very seldom do I read any magazine and find fewer things to pick at than this particular issue of

EBN. But I do have two. As we have discussed in the past, the name of CMHC, the Canada Mortgage and Housing Corporation, would seem to make more sense as the Canadian Mortgage and Housing... Read more

Scientists at the National Renewable Energy Laboratory (NREL) in Golden, Colorado, have achieved a new world record in thin-film photovoltaic cell efficiency. A record 17.7% “sunlight-to-electricity” efficiency was achieved with a compound semiconductor called copper indium gallium diselenide. While this efficiency is 60% higher than the... Read more

With great interest, I read your well-researched article on cork flooring in the January/February issue (Vol. 5, No. 1). As you concluded in the article, the harvest of commercial cork from the cork oak (

Quercus suber) tree is a relatively benign extraction that is one of nature’s best examples of a renewable, non-timber forest resource... Read more

The world’s first independently certified, “well-managed” redwood lumber is now available from the Big Creek Lumber Company of Davenport, California in the Santa Cruz Mountains. Big Creek sells redwood, Monterrey pine, and Douglas fir from its 6,800 acres (2,750 ha) of forestland. The Scientific Certification Systems evaluation team called Big... Read more

U.S. greenhouse gas emissions continued to rise in 1994, totaling 1,666 million metric tonnes carbon equivalent according to the report

Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-1994 published by the U.S. Environmental Protection Agency, November 1995 (this figure does not include the net effect of carbon “sinks” in... Read more

When homebuilder Barbara Harwood stumbled across the quote for a new mechanical system for a grocery store owned by her husband, she knew that the loads were out of line. The quote called for a system... Read more

Using the natural cycles of plant and animal life instead of chemicals and mechanical systems to process wastewater holds a great deal of attraction. Conventional sewage treatment systems already rely on bacteria to do much of the work, but these organisms perform very restricted functions within a system that is generally mechanistic....

A plethora of stay-in-place insulating concrete form building systems have been introduced in the last decade. Among these is the Rastra system—a European technology that is now getting established in the western United States.

The Rastra system uses 100% recycled expanded polystyrene (EPS) foam, ground into small beads and mixed with... Read more

The March 1996 issue of

Energy Design Update reports that fire tests at a laboratory in California have demonstrated that spray-applied cellulose insulation can be a more effective fire stop than conventional wood firestops in a 2x4 wall. The testing was done as part of an effort to gain Uniform Building Code (UBC) approval for the... Read more

We were pleased

Environmental Building News (EBN) gave a positive review to the American Forest & Paper Association’s (AF&PA)

National Wood Recycling Directory but somewhat disappointed with your opinion of our industry’s recycling efforts.
