procured to the building. Use this to calculate the percent of annual site energy use that is allocated to the Interiors project (incremental credit cannot be claimed in the Core and Shell application above the percentage documented).

Incremental to the renewable energy required for the base building for LEED BD+C: Core and Shell EAc3: Renewable Energy If the building owner supplies or procures renewable energy in excess of that used to achieve Core and Shell certification, the owner may assign this excess usage to tenants in the building. For example, the owner may offer an opt-in lease agreement to provide 100% Tier 2 renewable electricity to tenants in excess of the 100% base building site energy use secured for Core and Shell certification.

Project Energy Source

Renewable electric generation from Tier 1, Tier 2, and/or Tier 3 can only be applied to electricity or district thermal energy up to 100% of total combined electricity and district thermal energy. Tier 3 renewable fuels can only be applied to project fuel use or district heat up to 100% of the total combined fuel and district heat.

Therefore, if the project’s systems use any fuel:

  • The qualifying combined Tier 1 and Tier 2 energy use as a percentage of tenant annual site energy will be less than 100%.

  • The project must procure both Tier 3 electricity and Tier 3 renewable fuel to achieve 100% Tier 3 renewable energy required for two points.

Vintage

Renewable energy cannot be generated more than 18 months before the initial submission date for LEED certification.

  • A one-time purchase of EACs or RECs cannot occur more than 18 months before the initial submission date for LEED certification unless the terms of the purchase agreement ensure renewable energy generation occurs no earlier than the referenced date.

  • Allocation of renewable power to the project from a multi-year contract must be limited to power generation beginning 18 months prior to LEED initial submission.

Location For projects in large countries such as the United States, India, and China, the renewable energy must be generated in the same country as the project. For projects in smaller countries
