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

Solar PV System Degradation

Our Solar PV system supplier provided us a calculation of how much solar energy is generated per annum. It is projected that there will be a solar degradation factor of 1% each year. The calculation is projected up to 25 years. Since there is a decrease of energy generated each year, is it advisable to use the generated power on 1st year of operation when claiming savings on EAp2/EAc1?

I would not use the first year (best case). I would use an average year in the middle of the projected life for the output. This is a conservative approach.
