Sign board at construction site entrance

KC, there are LEED policy documents which address legal and trademark points like this. Without referencing them, I would recommend not using such signage. Although it doesn't say that it is LEED certified, it's not clear what it does intend to say or mean. Someone unfamiliar with LEED (i.e. most of the general public) could easily assume that the site was certified or had some LEED imprimateur, when in fact it is at this point probably no more than registered and pursuing various credits.Again, I didn't review the LEED policies before posting this, but I would think that language such as "XYZ project is attempting LEED Gold certification" or "A LEED-registered project" or "We're going for LEED—we need your help!" would be more accurate and reflective of a message appropriate for this stage in the work.

KC,

See the link below for official policy, page 25 covers registered projects:

You CAN say, for example, "This project is registered under the LEED®
green building certification program." But not "this is a LEED project."
