I think group certification would be a good option for my two identical (mirrored) buildings on the same property with the same owner. Can I register one now, then wait till group registration is available on LEED Online, and then add the other building in a few months time? Or get a voucher to reregister? I can’t find the difference in cost to register and certify as two individual projects or as a group including two buildings. Where do I find that information? (Customer wants to know). Thank you!
