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

District cooling PV array

If the project is district cooled with option 1 where the cooling energy consumption is determined by adding chilled water meter in the energy model for EAc1, in calculating the capacity of the PV array, is it right to convert then add the BTU reading from the chilled water meter to the total annual energy use to show compliance?

The EAc2 calculation is based on energy cost. Energy cost includes the cost of all energy end uses.

Thanks Marcus! We've just learned from "Treatment of District or Campus Thermal Energy in LEED V2 & 2009" reference page 15, that our project cannot earn EAc2 points using option 1 but option 2 could. Can someone enlighten us why is that? Is there a CIR that we should be aware about?

Option 2 accounts for the effect of the DES and any connected renewables. Option 1 does not. So if you are not going to account for the DES effects then the renewables connected to the DES don't count either.

Even if the renewable energy supplies energy only for the project?

If the renewables feed into the building and not the DES then it can count.

Dear all, we are working on a industrial + offices building and the thermal Energy is producted by renewable biomass. I would ask if the biomass energy should be based on local gas cost or local biomass cost to obtain the percentage of the building's annual energy cost. Thanks in advance Gabriele

Use the local biomass cost identically in both models. Then subtract the cost of the biomass fuel as a renewable under Section 1.8 in the form.
