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

Form

The EAC2 Form asks for "Annual Renewable Energy Cost". You said in a post that is "It is the avoided energy cost associated with the renewables at the virtual rate from the Proposed model. So it is the savings." So, if my system generates 49,725 Kwh/year and the Average energy rate is R$ 0,32 the annual renewable energy cost is 49,725 x 0,322 = R$ 15,912 Is that correct???

Sounds right. Just make sure the "average" rate is the virtual rate. The virtual rate is the total kWh consumed in the model divided by the total electric cost. The rate in the model can be entered as a simple rate $/kWh or as a complex rate with tiers, demand charges, rachets, etc. In the case of a simple rate it is the same as the virtual rate.

Marcus, good morning. you said that the virtual rate is the total kwh consumed in the model, divided by the total eletric cost. would not the opposite? the cost divided by the consumed?

Another question: In Brazil we have different rates of values according to the consumption of time. for example: in schedules where energy consumption is considered high the rate is R$ 1.95 and the times of small consumption rate is R$ 0.32. Do I have to consider the average? can I include in this value the taxes?

Yes reverse it. $/kWh is what you want.. You can use some type of average - this is the simple rate I mentioned above. You can enter the rate schedule in the model and it will apply it to your consumption - this is the complex rate I mention above. We will generally use the actual rate in our models as this would produce a more accurate result.
