Here is a review of key LEED 2009 addenda to date. The following covers BD&C systems: NC, CS, and Schools.

Update! See our ongoing coverage of LEED Interpretations and addenda here.

Last month USGBC issued a memo opening a new path to LEED points for professionals with green building credentials other than the LEED AP (LEED Accredited Professional) credential.

Last month USGBC issued IDc2 (IOc2 in EBOM), the new path is part of IDc1: Innovation in Design.

Filed February 7th, 2011, the amended complaint has been boiled down to a claim of false advertising, and is no longer a class-action suit.

From LEEDuser's sister publication Environmental Building News:

USGBC has launched a new program aimed at larger LEED customers—building owners and property managers certifying 25 or more LEED projects within a three-year window.

The LEED Volume Program, launched at Greenbuild 2010, is designed for government, education, real estate organizations, retailers, and the hospitality industry. The fledgling program has already engaged eight organizations, according to USGBC.

“LEED Automation,” the beginning of a new model for LEED documentation and reporting

With a new initiative called “LEED Automation,” the U.S. Green Building Council has announced the beginning of a new model for LEED documentation and reporting. Currently, teams submit LEED project data for review by entering it into the LEED Online website. LEED Automation makes it possible to collect that data in third-party applications and upload it for review without going through the LEED Online interface. “The world of LEED execution just got faster, better, and cheaper,” promised Mike Opitz, USGBC’s vice president for LEED, at a Greenbuild 2010 session.

I spoke with USGBC's Corey Enck to understand the proposal a bit better.

Among the key changes coming down the road for LEED, as I recently wrote about (Your Guide to the New Draft of LEED), is a change to the LEED AP credit, formerly IDc2, now dubbed IPc2 (that's "Integrated Process" credit 2).

USGBC staff will be monitoring this forum, and we will submit all comments on the new LEED draft as public comments, on your behalf.

Update: Learn about the LEED 2012 3rd public comment period, March 1–20, 2012.


USGBC has released complete revisions of its LEED rating systems, and has opened a first public comment period, going from Nov. 8 to Jan. 14, 2011 (extended from Dec. 31, 2010).

A process for precedent-setting rulings for project teams using the LEED rating system is under development at the U.S. Green Building Council (USGBC). The resulting “LEED Interpretations” process is to be unveiled in the Fall of 2010.

We'd been expecting something like this for a while—it's great to see that it's on the way.

Parking Generation is a compilation of parking capacity data collected by volunteers through surveys.

by Emily Catacchio

Pursuing SSc4.4: Alternative Transportation—Parking Capacity in the LEED 2009 NC, CS, and Schools rating systems just got a little more expensive for some projects—$118.75 more to be exact.

It's trivia Friday at LEEDuser.

See the answer to last week's question about MR credits here. This week:

Which of the folllowing is NOT a true statement about the history of LEED?

A) Rob Watson, a senior scientist with the Natural Resources Defense Council (NRDC), took over as chair of the USGBC's rating system committee in 1995, with LEED being conceived under his chairmanship—earning him the "father of LEED" nickname.

Be aware of the following update to the submittal documentation for LEED-CS v2.0 EAc1.

The following email from USGBC was just forwarded to me by a LEED-CS project team administator. I thought it was worth sharing for anyone who might not have seen it.

TO:  All Registered non-certified LEED-CS v2.0 projects 

Be aware of the following update to the submittal documentation for LEED-CS v2.0 EAc1.

Attending my first presentation on Green Globes, I was suspicious, but interested to get the low-down on how it works.

by Joshua Radoff

Last month, I heard my first presentation on the Green Globes rating system. I felt like the Bishop of Canterbury hearing Henry the VIII tell me about this new "Church of England" he was planning to roll out. That is, I was suspicious, but interested to get the low-down on how it works with a real open mind, so that I might know what the future may or may not hold. I have to say, I find some of the innovations to be really good.

The second public comment period is open from April 19th to May 18.

It's been a long time coming (since November 2007), but USGBC today opened a second public comment period for LEED for Healthcare!

Sixty-two credits and prerequisites, and almost all have changes, though most are minor and are about aligning LEED for Healthcare with the LEED 2009 rating systems. Some of the more significant ones are:

And Tips to Avoid Them

Snafu #10: Being threatened to be hung from the construction crane if the project doesn’t earn LEED Gold.

LEEDuser tip: Create a detailed checklist with tasks delegated to individual team members, allowing each member to focus on assigned tasks. The checklist can function as a status tracking document and, finally, the deliverable for LEED Online.
