FAQs about EAc2 :

We have a PV array installed on our campus, under the same ownership, but not on the building or within the LEED project boundary. Can we count that toward EAc2?

Because of how our onsite PV system was financed through the utility, the project is selling the RECs associated with its solar energy production, even though we own the PV array and its power. Is there any way we can earn EAc2?

Can I pursue this credit if I am using one of the prescriptive compliance paths for EAp2/EAc1?

Can I really double-count onsite renewable energy in both EAc2 and EAc1?

Our PV system is being installed after the building is occupied. Is that okay?

Our project will have a PV system onsite, but it will be installed, operated, and owned by a separate entity that is paying for the system through a premium price per kWh paid by the utility, per state regulations. Is there any way to count this toward th

A biofuel-based cogenerator is being used to produce both electricity and heat (CHP). Can I consider all the energy produced, or just the electricity?

Can a backup generator qualify, if it runs on biofuels?

NC-2009 EAc2:On-Site Renewable Energy

EAC2 in a Positive Energy Building

We are certifying a Positive Energy Building, that will produce 130% of its energy consumption with solar PV. All the energy produced with the PV will be sold to the grid. I was wondering if we could get any credit for the PV, considering that the building produces 30% more energy than it consumes, and, thus, this "extra" 30% needs to be sold to the grid, since the building cannot consume it. Does anybody know how to treat cases like this? Thank you Milena

Check the interpretations on this issue. I recall that the PV power must be fed into the building, not the grid, in order to count at all. It is possible that has changed. If my recollection is correct the fact that it produces 30% is moot. IMO if the PV is just feeding to the grid then your building is just a big PV rack not a net positive building.
