I have a project that is a new building located on a previous certified LEED project with PV production. The previous project had >90% offset by energy use and >100% offset by cost from renewable energy. The project was certified under v2009, and both Optimized Energy and Renewable Energy exceeded way above maximum threshold (50% and 15% for EP). Initially, there was no plan for campus approach, therefore no letter was written to allocate % of production to that project.
My question is, can I allocate part of PV production in previous project that exceeds 15% Renewable or 50% Optimized whichever greater, in both renewable energy production and optimized energy for my new project? If so, is it enough to use results from previous energy model to justify, or do I need to obtain utility data the back up the claim?
