Inquiry
Is it acceptable to use a mix of 10% biofuel and 90% natural gas to meet the requirements of EAc2, and is there a minimum time period for which the biofuel must be purchased from the utility company?
Ruling
For biofuels to qualify, the bio-gas system must meet the requirements as per table 3 of EAc2 as per the LEED-NC v2.2 Reference Guide and a signed declaration from the provider that clearly shows the source must be provided. The intent is for a portion of the building\'s energy to come from biofuel for the duration of its existence. Applicable internationally.
