Another Greenbuild conference has come and gone, with its frenetic activity, informative educational sessions, many meetings, and all-important networking.

This year I focused much of my time and attention on the Product Expo—and it took a lot of both! At the U.S. Green Building Council’s first Greenbuild conference in Austin, Texas, eight years ago, there were just 250 exhibitors; in Phoenix there were 1,100 spread over 11.5 acres (4.7 ha) in two exhibit halls at the Phoenix Convention Center. I scrambled to walk all those aisles and stopped at a good many—though certainly not all—of the booths. On the following pages are some brief snippets of what I found most exciting, covering almost 40 products and services. I feel very good about most of these products, though a few raise some doubts. This is by no means a comprehensive list of what was there; I may well have missed some particularly exciting new products. But for those who weren’t able to get to Phoenix in November or didn’t have time to make it through the expo, this survey offers a glimpse of some companies and products that stood out from the rest. I invite you to share your comments with your own observations—products I missed or misunderstood, or anything else noteworthy. READ MORE AT BUILDING GREEN
