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?

Hi to target this credit for a new project do you need an energy model to predict what 1% energy cost of is there an alternative approach ? We currently don't have an energy model for this project.

It depends on the method you are using for EAp2 compliance. If you are using Option 1 there you need to use the energy model to determine EAc2 compliance. If you are using Option 2 or 3 for EAp2 then you can use the CBECS method for EAc2.

Is the CBECS still relevant of projects outside the US?

In addition to my query below can we not use the excel calculator that is in the documentation toolkit under this credit above.

Yes international project can use the CBECS option. I have never seen that calculator used in a LEED submission. Use the credit form to document this credit.
