My client is producing enough energy on-site (solar) to get all the points in EAc1 and EAc2 with a large surplus of renewable energy. They have decied to sell the remaining on-site renewable energy (the energy not being used to satisfy the LEED credit requirements) as SRECs. Can any of the energy produced on site go towards fufilling EAc6 or is this credit only applicable to buying RECs from an outside source (not producing it on site)? Thanks.
