Our porject is a manufacturing facility that produces generators and converters for wind turbines. A component of the manufacturing process is the balancing of the generator rotors. A simplified explaination is that grid energy is used to spin the rotors, however, at the end of the rotor balancing process, the rotors are slowed down by a generator (dynamo effect) which is projected to produce 25,600 kwh per year and will be recycled back inot the building's energy system to power the lights and HVAC. The energy savings per balancing cycle is about 1.6 kwh. Would process qualify for the Onsite Renewable Energy credit.

Hi Ken,
Eligible on-site renewable energy systems include photovoltaic, wind, solar, biofuel-based electrical, geothermal (some restrictions) low-impact hydro and wave / tidal systems. The energy is originally generated from a non-renewable source therefore I doubt a LEED project reviewer would allow this process to qualify for EA Credit #2.
You could have the energy modeler deduct the 25,600 kwh/yr from the proposed annual energy consumption to help improve the point total of EA Credit #1.
