Dear Green Gurus: I'm so sorry to have missed seeing many of you at AIA last week. I heard the BG and COTE events were the highlights of the week! Congrats.

I'm sure by now you've heard of the dreadful Supreme Court decision about the EPA. I thought I'd share a helpful, if not sobering, perspective in an Op-Ed today in the Washington... Read more

A brief non-technical rant about OneClick LCA - from someone who is not actually USING the tool, but lobbying for its access.  Wondering if you all have better intel, or if it is just me.

Hi there colleagues!

Out of curiosity, do you plan on attending Greenbuild in person in San Diego in September? My staff asked me if we were going and my answer is partially contingent on the extent to which attending would mean getting to see some of our favorite people (read: all of you). Looking forward to taking the temperature of... Read more

If only a few of the Best Practices will have checklists, which will be included under the "Implementation Toolkit" tab, I'm thinking we can simplify them (compared with LEEDuser).

I've attached a screenshot of a LEEDuser checklist. But I don't think BITuser will need the four types of icons, and the legend will take up more space than... Read more
