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?

NC-2009 EAc2:On-Site Renewable Energy

Biomass Boiler

Our project, a small non-profit farm house renovation, is using a wood fired biomass boiler. Wood for the boiler is timber blow-down from the 917 acre largely wooded property contiguous to the project site and owned by the same owner. EAc2 allows for "untreated wood waste", but states that "forestry biomass waste" is ineligible. I am making the assumption that blow-down is untreated wood waste and that forestry biomass waste is a by-product of timber management practices. Does anyone want to weigh in????

With "untreated wood waste" I think we're talking about lumber waste from the construction industry."Mill residue" is sell-explanatory and clearly doesn't apply here.The question is whether this is "forestry biomass waste" or "agricultural crops," which I would strongly consider. I think that if you have a forest management plan that calls for certain management practices, including harvesting of blow-down, then it should qualify under this credit. In the absence of a forest management plan I would not try to argue for this, however. Harvesting blow-down may seem benign but could really do damage to an ecosystem if not done properly. A management plan provides assurance to LEED that you are doing the right thing.I don't have experience with this but that's my analysis. Anyone else have thoughts?
