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, does LEED recognize the biomass from energetic crops such like: -short rotation coppice (Poplar and willow include) -Grasses and non-woody energy crops (Miscanthus and Hemps included) Thanks for help

Eligible biomass includes agricultural crops. This is not very well defined. Sounds like you may be able to make the case that your fuel sources come under this type. It is likely that you would need to own the fuel source in order to claim its use but there are exceptions to the on-site nature of the source. You might also check the LEED Interpretations to see if any of these sources have been formally asked about before.

Marcus you said that I need to own the fuel source, what does it mean ? I know that the CHP operator buys biofuels from the suppliers, is that not recognized by LEED ? Do you know if UGBC published some paper about LEED recognized Biofuels?

I was not aware that you were taking about a CHP situation. Are you using the DES v2 guidance for how to include CHP in your models? If so there is some guidance on how to count renewables. Other than looking through the LEED Interpretations I am not aware of any other source of information.
