Hi all - I wanted to see if anyone will be in the Chicago area for the upcoming ASHRAE conference (21-23rd) and is interested in an informal meet-up? Or if you aren't going but are already in the Chicago area? Let me know and I'll see if we can organize meet-up!

Hi everyone,

It was so wonderful to meet some of you last month and experience the whirlwind of a summit! I hope you've enjoyed looking over the Summit Report and the flip chart notes, and they've helped bring some order to the vast amount of material we covered. Here's one more piece for you - slides from the 5-minute presentations.... Read more

Greetings, Green Gurus:

As unbelievable as it sounds, the Environmental PROTECTION Agency has launched a PR blitz in support of their "new use rule" on asbestos. So the BuildingGreen community needs to push back harder.
