The project may achieve the maximum number of points for Green Power, and an innovation point by complying with the LEED v4 requirements for Green Power and Carbon Offsets, with the following changes to reflect carbon offsets as an approach:
35% of total annual building energy consumption for a period of two years (or 70% for an innovation point) must be addressed by green power, RECs, and/or carbon offsets to qualify.
If using directed purchase of biogas, documentation must be provided showing that the biogas used for directed purchase is Green-e certified or equivalent, and the building ownership retains the environmental attributes associated with the directed purchase. (Note the v4 requirement is 50% or 100% of the total annual energy consumption for a period of five years).
