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.
