Horizzontally attached bldg addition to Non Certified building

I don' think there are any area restrictions for horizontally attached additions.

They do not need to be physically separated. A door is fine.

Sounds like the right system to me.

Hi Marcus, I have the very same situation with him. A new building addition horizontally attached to a non-LEED existing building. We have submitted for Preliminary review and here is the comment from the reviewer (I put numbering to separate each sentences):

1.0 If the existing buildings to which a LEED project is attached are not LEED certified, then the project name must include a word such as "addition" or "wing" or otherwise identify itself as separate from the other buildings to which it is attached.

2.0 And signage must be installed to mark the distinction between the LEED project and the existing non-LEED buildings to which it is attached.

3.0 Provide documentation confirming that the LEED project building is separated from the attached buildings by both ownership and management or space usage type.

4.0 If the existing buildings are not LEED certified, revise or clarify the LEED project title and provide documentation (example signage or narrative) that demonstrates how the LEED project will be distinguished from the existing non-LEED buildings.

5.0 Examples of acceptable signage include providing the identifying project name and/or key plan adjacent to the LEED plaque display.

My inquiries for now:

Item No. 1: Can I rename the project title from originally "ROHQ Building" to "ROHQ New Building Addition", as stated in comment no. 1?

Item No. 3: Is a documented letter signed by the owner/management confirming that the new addition building is separated from the existing non-LEED building - acceptable for this situation? If it is acceptable, Where can I upload the signed letter and supporting documents required by PIf1?

Sorry for the double posts.

Addendum:
Item No. 2: What if we mark the project as private - do we need to post the required signage for distinction?

1. Yes you can rename the project.
2. I think you probably still need the signs.
3. I don't think it has to be completely separate. A letter might help clarify the situation. I'd also provide drawings, etc. to show the situation clearly to the reviewer.

If you have not done so read through this document for more guidance - http://www.usgbc.org/resources/leed-2009-mpr-supplemental-guidance-revis...

And to upload documentation to PIf1, just click the Special Circumstances box. On all forms, this will open up a text field and an upload section allowing you to add more clarifying information.

Thanks a lot Marcus and Kristina!
