Option 2. Renewable Energy

This option establishes a three-tier hierarchy for renewable energy, preferentially rewarding renewable energy supply and procurement that has the most direct and long-term impacts on building decarbonization:

  • Tier 1 . On-site renewable energy generation or social impact project

  • Tier 2 . New off-site renewable electricity

  • Tier 3 . Off-site renewable energy

For all three tiers of renewable energy, it is recommended that the project team first confirm that the project will comply with the credit requirements for renewable energy environmental attributes and renewable contract length before proceeding with procurement and/or installation of the renewable energy.

Annual electric use calculations For each Tier, credit is awarded based on the percentage of annual renewable supply or procurement compared to total annual electric use for the building, as reported in EAp3: Minimum Energy Performance .

If the project claims credit for Tier 3 renewable fuels, the numerator includes all annual Tier 3 fuel and electricity procurement, and the denominator includes only project annual electricity use.

RENEWABLE ENERGY CLASSIFICATIONS

Tier 1. On-site Renewable Energy Generation or Social Impact Project

To qualify as a Tier 1 renewable system, the renewable energy must be produced and generated on the project site, on the site of the contiguous campus where the project is located, or on the site of a social impact project.

Eligible Tier 1 renewable resource types Eligible Tier 1 renewable energy resources include:

  • Solar electric (photovoltaic)

  • Solar thermal (i.e., for service water heating or hot water heating)

  • Wind

  • Recovered heat from municipal wastewater

Only usable energy generated from the renewable system shall be considered toward the Tier 1 renewable energy contribution. Usable energy is defined as the output energy from the system
