Have questions about LEED v4? We have answers.

Published on Written by Posted in LEED

Are you an energy technical solution provider wondering how you can help LEED projects achieve the new Demand Response credit?  Are you a practitioner who wants to know why air testing is valued at two points when the flush-out is valued at 1 point for the EQ: Indoor Air Quality Assessment credit? Or perhaps you're a building owner who wants to know overall how the changes in the water credit category of LEED v4 will effect your existing building's pursuit of LEED.

Whatever your question, log onto Twitter May 22 from noon to 1 p.m. to get answers from USGBC's very own VP of LEED Technical Development, Brendan Owens, who will be tweeting from our @usgbc handle. To join the conversation, make sure you are following @usgbc and use #LEEDv4 when asking a question. He'll be ready to answer a wide-range of LEED questions, from the super-technical questions to the more general.

And don't forget – the LEED ballot opens June 1, 2013, for all those who have registered.

Has the date to register a new project under LEED 2009 vs LEED V4 been extended beyond June 1, 2015? In association with the registration deadline, is there a project completion/occupancy date to qualify under LEED 2009? (mid 2020?)

Hi, I am working on a commercial interior design project. The client owns the entire building but currently wants to redesign one wing which will be their test pilot. The wing is oven to the rest of the building. They want the wing to be LEED certified. Is LEED ID+C the best option even though the client owns the entire building and is not "leasing" a separate space? They do want to renovte the entire building eventually. Thank you!

Hi Maxine, That sounds reasonable if each phase of renovation is being treated as a separate construction project and affects a physically discrete portion of the building. I'd recommend that you first have a look at the Rating System Selection Guidance for v4 ( to be sure you select the appropriate adaptation of the Interior Design + Construction (ID+C) rating system. Then, you should also verify that the project can comply with all three Minimum Program Requirements (MPRs), before you actually register it. The certifying space of an ID+C project can belong to the building owner rather than a separate 'tenant', per se, but as explained under the heading "Interiors" in the Additional Guidance for MPR 2 (, "The LEED project should be defined by a clear boundary such that the LEED project is physically distinct from other interior spaces within the building." It sounds like your proposed project may be able to comply with this stipulation, but if you have any concern about that or other issues please use the Contact link at the bottom of this webpage to reach out to us with more information for additional feedback.

What determines whether a remodeling project is a "Major Renovation" vs. an "Operations & Maintenance" repair project? I am involved with a roof repair project for an 8,000 sf office bldg with a leaky roof that may involve: replacement of the entire roof; conversion of 75% of the roof to an ecoroof system; a new Mechanical & HVAC system; replacement of all windows; and some reconfiguration of the interior partition walls; all aimed at LEED Silver certification. The building footprint and exterior walls will remain the same, aside from the new low-energy windows.

LEED v4 question as to which rating to use. I have a 75,000 SF academic building, 3 floors with various multipurpose class labs supporting art, music and theater as well as faculty offices, art, English, communications & learning support classrooms. Is it better to use LEED v4 for BD+C: Schools OR LEED v4 for BD+C: New Construction? Thank you, Katy Sheesley

Hi Katherine – great question. Have you looked at the updated Rating System Selection for LEED v4? That's the best place to start. If the academic building will be used for k-12 students, I believe BD+C: Schools is the rating system for you but would need more details to make a formal recommendation. Feel free to email me at
Hello, When do I have to take the LEED AP test by before the testing will be switching over to LEED v4? Thank you

The last day to take the credential exams with LEED v2009 content will be June 15, 2014. The first day to take the exams with the new LEED v4 content will be June 30, 2014. No tests will be administered in between these dates.

After v4 launches in November, will the cost to register under LEED 2009 increase? What will be fees be for 2009 registration vs. v4 registration?
