When green power is not Green-e certified, the project team can still pursue the Energy and Atmosphere Credit for Green Power by demonstrating that the purchased green power meets equivalent standards. This involves providing documentation that verifies the green power's quality and production process align with the criteria set by Green-e certification.
References: The LEED v4 Reference Guide for Interior Design and Construction includes provisions for using green power that is not Green-e certified, as long as the project teamcan substantiate its equivalence. This can be done through third-party verification and ensuring that the energy source meets the requirements for renewable resources detailed in the current version of the Green-e standard123.
