Energy Standard for Canada and the United States, Section II (Eligible Sources of Supply).

  • Be from renewable assets that have come online within the last 15 years, or for projects outside the U.S., the eco-label program may instead include provisions ensuring incremental environmental benefits for assets older than 15 years.

  • Have a verifiable chain of custody.

  • Have a mechanism to prevent double counting.

For Tier 3 fuel, the EACs retired on behalf of the LEED Project must have a mechanism to prevent double counting and meet one of the following criteria:

  • Certified under an eco-label or similar program developed by an independent organization with transparent accounting process and standards in place, OR

  • Officially recognized as a renewable fuel source in the country, province, state, or locality in which the project is located.

DISTRICT ENERGY SYSTEMS (DES)

District Energy Systems Fueled by Renewable Energy

For District Energy sources fueled by renewable energy, projects may either allocate this renewable energy towards credit compliance, or exclude the renewable energy proportion from the project’s annual site energy determination:

ALLOCATION OF DES RENEWABLE ENERGY TO THE PROJECT For each district energy source serving the project, assign the project the proportion of DES input energy that meet the LEED requirements for each Tier of renewable energy:

o Tier 1 . On-site renewable electricity generation or solar thermal energy generation at

the District Energy Plant.

o Tier 2 . New off-site renewable electricity.

o Tier 3 . Green-e® or equivalent off-site renewable electricity for DES electricity

inputs, or Green-e® or equivalent fuel for DES fuel inputs.

For example, allocate the project Tier 3 renewable fuel totaling 60% of the project’s annual district heating energy consumption for a district heating system with 60% of annual energy inputs from Green-e ® or equivalent fuel. EACs must be retained by either the DES supplier or the project owner to be eligible for this approach.

In place of documentation showing a 10-year contract for renewable fuels, the project may submit evidence of annual DES renewable percentage achieved for the most recent three years
