FAQs about EAc2 :

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

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?

PV as a source of energy for ground heat exchange

A project I'm working on is considering a combination of PV and ground source heat pump. The PV will generate approx. 30 kW of energy and this energy will be fed into the heat pump that will use this energy to provide approx. 120 kW (COP of 4). PV is considered a renewable source of energy, while heat pump is not. I'm not sure if I we can consider the 120 kW renewable or only the original 30 kW. How would you assess this case? Thanks.

Only the PV counts as a renewable. It is energy production, the heat pumps are energy consumption.
