I´m trying to set how many RECs I must buy to comply with this credit for a project of 59,545sqf. According to Reference Guide I should multiply this area by 8kWh for 2 years (59,545 x 8 x 2), requiring a 952,735kWh purchase. Althought when filling LEED online template it cames as return a information as "Green Power per sf over a two year period" of 839.7kWh/sf. What does that mean? What calculations should we consider. I´m a lot confused.

Thanks,
Juliana Malho
