For a building pursuing LEED Platinum certification, the consultants you’re looking for are typically called LEED certification consultants, LEED coordinators, or sustainability consultants.
Their main job is to manage the LEED scorecard and point documentation, coordinate evidence from the architect, engineers, general contractor and vendors, and prepare the submission to the Green Business Certification Inc. (GBCI). They also help identify achievable credits and keep the team on track toward the Platinum threshold.

What to ask before hiring
For a Platinum project, I would ask each firm to confirm that its proposal includes:
- LEED scorecard management: maintaining a live credit tracker and forecasting whether the project will reach Platinum.
- Documentation ownership: collecting, reviewing and uploading evidence from all disciplines into LEED Online or the applicable certification platform.
- Credit optimization: identifying practical additional points and maintaining a buffer above the minimum certification threshold.
- Submission and review management: preparing the application, submitting it to GBCI and responding to reviewer comments.
- Relevant project experience: completed Platinum projects using your building type and the applicable LEED rating system.
The USGBC recommends assigning clear ownership for each credit and maintaining consistent documentation throughout the certification process.
Let me narrow this to the right consultants
One detail will make a big difference in which firms I recommend: is your building a new construction project or an existing building going through LEED O+M certification?
If you tell me which one, I can narrow the list to the most relevant specialists for managing your Platinum point documentation.

- dgs.dc.govA. It is important that the project team designate a **LEED coordinator**, someone who can manage the process and keep all team members on track throughout the project. Although many project teams elect to hire a third-party sustainable design consultant for this role, it is not always necessary if there is a team member with some LEED experience under their belt. This Guidebook will use the term ‘LEED coordinator’ in reference to either an internal or external (third-party) LEED coordinator or green building consultant.

The professionals who specialize in managing LEED point documentation, coordinating the integrated design/construction team, and steering the submittal through the
Green Business Certification Inc. (GBCI)review process are generally known by the following titles:- LEED Consultant (or Sustainability Consultant / Green Building Consultant ): The primary advisory role hired specifically to oversee the rating strategy, map out achievable credits, manage the online documentation platform (LEED Online), and act as the liaison to GBCI.
- LEED AP (Accredited Professional) with Specialty : This is the formal credential a consultant holds. For a commercial building, they will typically hold a LEED AP BD+C (Building Design and Construction) credential, signifying advanced expertise in the design and construction phases of green buildings.
- Sustainability Project Manager / Coordinator : In larger engineering, architecture, or dedicated commissioning firms, this internal title often belongs to the person doing the day-to-day administrative lifting, chasing down submittal templates, material data sheets, and calculations from subconsultants.
Depending on the specific credits pursued for Platinum, specialized sub-consultants also generate and sign off on technical documentation:
- Commissioning Authority (CxA) : Manages energy and water system verification (prerequisite/credit documentation).
- Energy Modeler : Produces energy performance and optimization documentation.
- Lighting/Daylighting and Acoustics Specialists : Provide technical modeling and calculations.
If you'd like, let me know:
- What phase your building is currently in (Design vs. Construction)
- Whether you are looking to hire an external firm or clarify an internal team member's role
I can help you outline a credit responsibility matrix or typical contract scope for a LEED consultant.

For a building pursuing LEED Platinum certification, the firms you want are typically called LEED consultants, green building consultants, or sustainability and LEED certification consultants. They help manage the documentation, coordinate with the architect and engineering teams, track prerequisites and credits, and prepare and submit the certification package to the U.S. Green Building Council (USGBC) through its LEED Online platform.
The most relevant firms are those that offer end-to-end LEED project management, not just energy modeling or sustainability design advice.
Firms to consider
Here are six firms with published services relevant to managing LEED documentation and certification. I've included Chicago-area options as well as firms serving broader U.S. markets.
1. Candid Sustainability
(Chicago-area option)
Offers full LEED administration and project management from early design through construction and certification. Services include assigning credit responsibilities, maintaining the LEED scorecard, collecting documentation, managing LEED Online submissions, and responding to reviewer comments.
Best for: Outsourcing the overall documentation and coordination process.
2. UL Solutions
Provides turnkey LEED project management from registration through certification, including documentation administration, commissioning, energy modeling, and technical credit support. It also offers construction-only LEED management for general contractors.
Best for: Large or technically complex projects needing documentation and engineering expertise.
3. Two Trails
Manages LEED scorecards, feasibility assessments, documentation, contractor templates, construction schedules, LEED Online, and certification review comments. Its published services cover design, construction, operations, and recertification.
Best for: End-to-end certification administration across different building types.
LEED consulting and administration
4. Green Badger
Specializes in construction-phase LEED documentation, including product submittals, material disclosures, low-emitting materials, waste diversion records, LEED calculators, and uploading supporting documents to LEED Online.
Best for: Reducing the documentation workload on the general contractor and subcontractors.
5. O'Brien360
Provides sustainability certification project management, documentation, and field verification. Its experience includes commercial LEED, residential LEED, and LEED Operations and Maintenance.
Best for: Projects that need documentation combined with on-site verification.
6. Engineering Economics Inc. (EEI)
Offers LEED credit targeting, documentation and submission, energy modeling, commissioning, indoor air quality testing, and life-cycle assessment.
Best for: Projects where the consultant must manage paperwork and provide the technical analyses needed to earn credits.
What should you ask a consultant to manage?
For a Platinum target, I would request a proposal that explicitly covers the following:
Service What the consultant should deliver Certification strategy LEED feasibility assessment and a credit-by-credit scorecard targeting Platinum Documentation management Responsibility matrix, evidence tracking, LEED Online forms and supporting files Design-team coordination Coordination with the architect, MEP engineers, civil engineer and landscape architect Construction documentation Product submittals, waste records, material disclosures, indoor air quality and site documentation Technical credits Coordination of energy modeling, commissioning, water efficiency calculations and other specialist analyses Submission and review Certification submission, reviewer comment responses, and final documentation through award Important: LEED Platinum is not guaranteed by hiring a consultant. Under the standard 110-point LEED framework, Platinum requires at least 80 points, along with all applicable prerequisites. The consultant should establish a realistic target early and track the project's progress against it.
My recommendation
If your building is in the Chicago area, I would start by contacting Candid Sustainability for comprehensive LEED administration. Compare its proposal with UL Solutions if the project requires substantial engineering and commissioning support. If the primary problem is collecting construction records and subcontractor documentation, evaluate Green Badger as well.
Before selecting a firm, verify its experience with projects that achieved LEED Platinum under the same rating system and building category as yours.
