• Vintage : EACs credited to the project must be generated no earlier than 18 months before the LEED project’s initial application submission date.

  • Location : Tier 2 and Tier 3 renewable assets must be in the same country or region where the LEED project is located.

  • Tier 2 bulk purchase : Green-e® Energy certification or equivalent is required for onetime purchase or annual purchase of EACs or renewable power totaling more than 100% of the tenant’s annual electricity use.

Option 2. Renewable Energy Readiness (1 point) — Core and Shell only

Design the project for renewable energy readiness. Document renewable energy readiness features in the project design and provide tenant guidelines indicating how tenants can leverage these features to install renewable energy capacity for their tenant space. Tenant guidelines shall include a copy of the construction documents or a comparable document indicating the information below. Projects shall either document solar readiness in accordance with the criteria below or an equivalent solar readiness standard, or document equivalent on-site renewable energy readiness for another qualifying renewable energy source.

SOLAR READINESS

Solar zone A designated solar zone shall be included in the project design.

• Designate a dedicated solar zone area equal to at least 40% of the gross roof area.

• Conduct an analysis to determine the most appropriate location for optimal location of the solar zone, avoiding shading from trees, buildings, etc., and accounting for future construction that may result in shading.

• Perform a wind and load analysis and confirm that the roof or other structure encompassing the solar zone is designed to accommodate all mounting configurations identified in the tenant guidelines.

• Total area shall be comprised of areas that have no dimension less than five feet and are no less than 160 square feet.

• No obstruction, such as vents, chimneys, or roof-mounted equipment, shall be in the solar zone or planned for future installation in the solar zone.

• Any obstruction located on the roof or other part of the building that projects above a solar zone shall be located at least twice the distance, measured in the horizontal plane, of the height difference between the highest point of the obstruction and the horizontal projection of the nearest point of the solar zone, measured in the vertical plane. (Exceptions: projects located within 10 degrees of the earth’s equatorial plane, or any
