leed certification process
LEED Certification Process
  • Register Project: The project team registers with USGBC.
  • Application Submittal: The project team submits two copies of the project application and the corresponding fee to the LEED Certification Manager.
  • Administrative Review: An administrative compliance review is completed within one week from the USGBC's receipt of the application. Each credit is reviewed for compliance and completeness. The technical review begins when the issues raised by the administrative review are resolved.
  • Technical Review: Within two weeks of administrative approval, the USGBC issues a Preliminary LEED Review document noting points earned, pending and rejected. The project team has 30 days from the receipt of the preliminary review to provide corrections and/or additions as a supplementary submittal to the application. The USGBC conducts a Final LEED Review of the application within 30 days of receiving the resubmittal and recommends a final application score to the LEED Steering Committee. The LEED Steering Committee accepts or rejects the recommended final application score within two weeks of receipt and notifies the project contact of the LEED Certification.
  • Award: Upon notification of the LEED Certification, the project team has 30 days to accept or appeal the awarded certification.. The USGBC presents the project team with a certificate and a metal LEED plaque indicating the certification level.
