Hi,
we are working in a project pursuing LEED certification (NC v2009).
The owner wants to achieve the Platinum Level and that implies an area of PVs larger than the area available at the rooftop of the building.
This new building will be built in a site that belongs to the same owner. This site comprises several existing buildings (not included in the new building LEED boundary). Two questions:
- Is it possible to use the roof top of one of these existing building to install some of the PV’s needed for the LEED platinum of the new building ?
- Local legislation allows the connection of PV panels to the national electricity grid. Thus, if PV panels production is higher than the building demand (e.g, during Sundays), the production of the PV panels is not wasted (it is sold to the grid). Can this revenue be accounted in energy performance credit (subtracted to annual energy cost of the proposed building) ?

1. Yes. PV on a campus can be allocated to a specific LEED project. The owner needs to provide an allocation letter.
2. You count the full output of the PV for a year. You are required to use the virtual electric rate from the Proposed model for the revenue. This revenue is subtracted from the proposed building's energy cost.

Hi Marcus,
Can PV from the adjacent building be allocated to a specific LEED Project even though the adjacent building or the campus is not registered with LEED?

Probably. Sounds like the adjacent building is on the same campus so it should be a matter of allocation. Look to the Campus Application guide for details.
