This pertains to REC's purchased at the corporate level:
My project is a large office building with multiple tenants. One of the tenants purchases a large share of REC's for their entire corporation every year. These REC's cover multiple offices in several locations. This tenant agreed to apportion some of these REC's to cover the electricity consumption for this project's performance period (7 months). I understand USGBC will require a 2 year contract, but can someone please confirm what other type of documentation is required for submission? Do I just need a letter from the tenant stating they are apportioning so many REC's to this building and these REC's will not be credited to any other LEED project? Also, can the 2 year contact begin before the perfomance period? Thanks!
