SITES Rating System
SITES is a sustainability-focused framework that ushers landscape architects, engineers and others toward practices that protect ecosystems and enhance the mosaic of benefits they continuously provide our communities, such as climate regulation, carbon storage and flood mitigation. SITES is the culmination of years of research and development by leading professionals in the fields of soil, water, vegetation, materials and human health.
By providing performance measures rather than prescribing practices, SITES supports the unique conditions of each site, encouraging project teams to be flexible and creative as they develop beautiful, functional and regenerative landscapes.
SITES-certified landscapes help reduce water demand, filter and reduce stormwater runoff, provide wildlife habitat, reduce energy consumption, improve air quality, improve human health and increase outdoor recreation opportunities.
SITES certification is based on a point system: the number of points that a project earns determines the certification level it receives. The SITES certification process allows projects to benchmark against performance criteria. The process is performed through SITES Online, which is a simplified tool designed to collect documentation and track projects from start to finish.
|SITES Certified||70-84 points earned|
|SITES Silver||85-99 points earned|
|SITES Gold||100-134 points earned|
|SITES Platinum||135+ points earned|
Eligibility and Fees
SITES certification applies to new construction projects as well as existing sites that include major renovations. The site must have been constructed within the last two years. There is no maximum size for a SITES project, but the minimum is set at 2,000 square feet. SITES can be applied worldwide to a variety of projects types (with or without buildings), including:
Local, state and national parks; botanic gardens; arboretums
Streetscapes and plazas
Retail and office areas; corporate campuses
Neighborhoods or individual yards
Public and private campuses; museums; hospitals
|USGBC and ASLA Members||Non-Members|
|Early Adopter Registration
(Available March 1 - May 31)
|Early Adopter Combined
(Registration + Certification)
|Combined (Registration + Certification)||$8,000||$9,500|
The registration fee is calculated on a per-project basis and must be paid at the time of registration. The fee is discounted for ASLA members and USGBC members at the Silver level and above.
The certification fee is charged on a per-project basis. It’s due before submitting a project’s application for a certification review. A discount is offered if certification and registration fees are paid together at the time of a project’s registration.
Guide to SITES Certification
A SITES certification marks a project’s commitment to sustainability. This guide covers the process, which involves four main steps. You also can download our free SITES Rating System for more information about prerequisites and credits for SITES certification.
Register your project by completing key forms and submitting payment to receive access to SITES worksheets.
SITES Online is a web portal that you’ll use to complete registration information related to your project; submit payments; sign the GBCI certification agreement; and access a variety of tools and resources.
At this stage, you’ll also assemble your project team, which includes at a minimum the owner (or owner’s agent) and the project administrator.
The owner is the person (or entity) who has the authority to hold and control the real and personal property associated with the project and accepts the certification agreement. If desired, the owner can grant authority to an agent to act on his or her behalf. The project administrator acts as a project manager, overseeing the SITES project as well as which team members are responsible for certain tasks, credits and prerequisites.
Collect and submit the necessary documentation to enable a GBCI review of your project.
Working with your project team, you should identify which SITES credits to pursue and assign them to members. Your team then should collect information, perform calculations and analysis, and prepare documentation demonstrating your achievement of the prerequisites and your selected credits. Documentation requirements are outlined in detail with examples and calculations in the SITES v2 Reference Guide (PDF, print). If you have technical questions during this process, you can send them directly to GBCI.
Before you complete the application and submit your project for review, you have the opportunity to request a conference call directly with your reviewer.
GBCI will conduct a thorough examination of your project.
GBCI offers two review paths for SITES projects: standard and split.
The standard review path is where you’ll submit your entire application. The split review — designed to let you know if your project is on the right path — allows you to submit part of your application at the end of your project’s design phase and the rest at the end of construction.
Once you select your overall path, there are several general stages of review:
Preliminary Review (20-25 business days)
Here, GBCI will determine if your project complies with prerequisites and attempted credits. You can accept the results from GBCI, or submit new or revised documentation for another review. If you have questions about the review comments you received, you have the opportunity to schedule another conference call with your reviewer prior to submitting for a final review.
Final Review (20-25 business days)
GBCI will review the resubmitted documentation (if any) for compliance. Just like in the preliminary review stage, you can either accept the results from GBCI, or resubmit your application as an appeal if necessary.
Appeal Review (20-25 business days, fees apply)
At this stage, you can submit additional information, modify your application, or add new credits previously not attempted. You can accept the results from GBCI as final, or submit a further appeal. There’s no cap on the number of appeals you can submit.
Sign off on your project’s final review.
Accepting GBCI’s final review is the last step in the SITES certification process. At this point you can no longer appeal the certification level or review decisions for specific credits or prerequisites. If you’ve earned certification, congratulations! You will receive a formal certificate of recognition, and you can begin to promote this achievement.
Revocation of SITES certification
In rare situations, a SITES certification may be revoked. We’ve created the Certification Challenge Policy to ensure that all SITES project proposals and subsequent reviews by GBCI team members are done so with integrity, accuracy and truthfulness. A certification challenge may be initiated by GBCI or by any third party within 18 months of a project’s certification. We recommend that you retain all project documentation related to your certification for two years in case of a challenge.
