FAQs about EAc2 :

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?

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?

Hi All, We have a campus with a substation on-site (on owner's property) that will be owned by the local utility. The Owner would like to tie in the power generated by an on-site solar energy production system at the transformer yard as the power is coming into the facility. Does anyone have experience with such a strategy? On the face of it, this seems to be unacceptable, but at the same time, it seems to meet the intent and spirit of the requirements and is therefore a candidate for a CIR request. Any thoughts?

Which side of the transformers would it tie into? Which side of the campus meter would it tie into? Who would own the solar system?

The utility side of the transformer upstream from the campus meter but within campus project boundary. Not sure yet who will own the system.

This will probably come down to an issue of ownership of the system and the contractual relationships rather than where it ties into the grid. It is cleaner if the power ties into the owner's side after the meter but it can tie into the grid. If the energy is sold into the grid it is not eligible. If the energy is purchased by the owner, who must also retain or replace the RECs, then it may be eligible. If the system is leased the term must be at least 10 years. Check into the campus guidance and LEED v4 for additional guidance on this kind of situation.
