Question: Jim asks: Is LEED certification for construction companies or for each individual construction project? Is there any type of “expiration date” associated with LEED or a LEED recertification? Thanks!

Answer: Hi Jim, Thank you for your question. LEED certification can be performed on a single building project, multiple buildings within the same project, or for qualified prototype buildings. LEED projects utilize the Green Business Certification Inc.’s LEED Online website,, in order to organize all credits and project team assignments. This makes coordination less complicated between the construction company, architect, and others associate with the project.

Within a construction company, individuals may choose to become LEED accredited, which will give them a greater understanding of the LEED process. Not to mention, having a LEED AP on the project will add one point to any LEED projects of which they are a member of the project team.

Information on how to become a LEED AP (Accredited Professional) is located on this website. There is no formal process for an entire company to become certified, only individuals within the company.

mark-morgan-LEED-platinum150As for your second question, there is no expiration date for most LEED certifications, per say, but there is a LEED recertification required for LEED EBOM (see below).

For LEED certification under any system, a project must first be registered with the GBCI (Green Business Certification Inc.) under the current rating system version. It may remain registered for as long as necessary in order to undergo the certification process. However, LEED is updated every few years and new versions are then created. If a project is registered during a time in which a new LEED version is released, it must either become certified within a given window of time or roll over into the new version. If it is not, it will be required to register the project again.

LEED EBOM (O+M) Recertification:

The LEED EBOM rating system addresses the building project’s “operations, processes, system upgrades, minor space use-changes, and minor facility alterations or additions”.

This rating system addresses building operations and maintenance issues such as cleaning, recycling, exterior maintenance and building systems. It applies to existing commercial, institutional and high-rise residential buildings of any size, public or private. Plus, buildings that have already achieved LEED certification can re-apply for EB:O+M certification.

It is important to note that EB:O+M is the only rating system that requires re-certification every 5 years.

This is to ensure that the certified building is actually performing according to LEED standards. If the building does not perform to these standards, certification may be revoked.

Good luck,
