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...

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
