I am working on a project that will have two wind turbines. Does anyone know what is a LEED acceptable means for calculating the wind energy (kWh) generated from them? The manufacturer has given us a value for the annual energy production that is a product of the rated power, a derate factor (efficiency losses), and the average wind number of hours per day the wind is at the required speed for full power. Is that sufficient? Is there a tool similar to PV Watts that is required/suggested for wind?

Thanks,
