A recent memo hints that the Department of Defense will accept Green Globes certification for buildings—but that was already the case.

It started with a press release from the Green Building Initiative, developer of the online Green Globes tool—“Department of Defense Recognizes Green Globes for Assessing Building Sustainability”—and it spread... Read more

I should have known I was in for something unexpected when I walked into this year’s Greenbuild session on “biophilia”—humans’ love of living things—in a dark, windowless auditorium.

The irony of the setting was not lost on the four presenters of “Biophilia; Moving from Theory to Reality.” Amanda Sturgeon, vice president of the Living... Read more

Bird-safe glass is worthwhile, but keeping cats indoors would prevent far more songbird deaths. A new study finds an estimated 105–348 million birds in Canada each year are killed by domestic cats, making these pets and their feral compatriots the biggest human-related threat to wild birds—more lethal by far than large office buildings and wind...

The new partnership aims to prevent apples-to-oranges product comparisons under the guise of life-cycle assessment and environmental product declarations.

“We’re working on filling in some of the gaps” with the underlying data that informs LCA, Firth told EBN. Although there are rules specifying how to conduct an assessment (see “The Product... Read more

Calling stone “natural” doesn’t cut it anymore: NSC 373 sets a new standard for quarrying, processing, and transporting dimension stone. Although stone has inherently green properties, its life cycle includes many environmental stumbling blocks (see “Stone, the Original Green Building Material”). A new NSF International standard developed by the... Read more

The new tool aims to help architects with whole-building LCA calculations for LEED v4 right along with their BIM process.
