It's Tuesday afternoon and I'm sitting in a seminar on smart building technology (yes, I came willingly) at BuildBoston, the Boston Society of Architects' annual conference.

There are a lot of people in here who clearly know what they're talking about — far more than me, certainly — but I just heard one of them refer to "the LEEDS." This is not uncommon, either. I hear it not seldomly, and among people, like these, who work in the building industries.

People, it's L-E-E-D but no S. It stands for Leadership in Energy and Environmental Design. Yes, there are a number of strains of LEED — for existing buildings, and new construction, and homes, and a bunch of others — but so far as I know, they're all called LEED.

My expectation is that, beginning tomorrow, across the way at the Boston Convention and Exposition Center, they'll at least be saying it right. LEED has built that show, the US Green Building Council's national GreenBuild trade show.

[An update, five minutes later] Maybe this is piling on; you decide. A presenter is making an analogy about security systems, and compares it to LEED. You know, "bronze, silver, gold, platinum, whatever." Sorry, but there's no bronze!]
