13.1 Contracts Between the Client, Certifier, Expert & Auditor
Key Takeaways
- The owner accepts, or authorises acceptance of, the certification agreement with the certifier; GBCI issues the registration invoice only after billing information is confirmed and a signed certification agreement is provided.
- The client contracts the EDGE Auditor directly and negotiates the Auditor’s fees and terms; those fees are independent of the registration and certification fees paid to GBCI.
- The contract with the EDGE Auditor must be in place before applying for certification, and only an Auditor listed by GBCI may be used.
- Engaging an EDGE Expert is highly recommended but is not required for a project to pursue EDGE certification.
- Where a firm offers both consultancy and audit services, the Auditor scope and fees must be listed separately from all other services on the proposal and contract, and the Auditor may provide no other services to a project they audit.
13.1 Contracts Between the Client, Certifier, Expert & Auditor
Exam Focus: Sub-topic 5.7 "Contracts EDGE client and EDGE certifier" sits in Domain 5.0, which carries 20% of the exam. Contract questions test whether you understand the independence architecture, not commercial law.
EDGE's integrity depends on who contracts with whom. Map it once and the ethics rules in Chapter 8 stop being a list to memorise and become an obvious consequence.
The Four Contractual Relationships
| Contract | Between | Purpose |
|---|---|---|
| Certification agreement | Project owner (or authorised agent) and the certifier (e.g. GBCI) | Establishes the certification relationship; must be signed before registration completes |
| Auditor engagement | Project client and the EDGE Auditor, directly | Commissions the Design Audit and Site Audit |
| Auditor Agreement | EDGE Auditor and GBCI | Licenses the individual to provide EDGE Auditor services |
| Expert engagement | Project client and the EDGE Expert | Commissions advisory and application-preparation services (optional) |
A fifth appears only at the top tier: a signed EDGE Zero Carbon Certification Agreement with GBCI is required to pursue Zero Carbon.
The Certification Agreement and Registration
Registration signifies intent to pursue certification, and the sequence is specific:
- The team creates the project in the EDGE App and clicks Apply for Certification, selecting a certifier.
- GBCI follows up by email, typically within two business days, requesting confirmation of billing information and a signed certification agreement.
- GBCI issues the registration invoice only once both are provided.
- The project is not considered registered until the registration invoice is paid.
The practical trap is treating "we applied" as "we are registered". A team that has applied but not paid is not registered, and deadlines that depend on registration have not started.
Who may sign
- The Owner is the person or entity with authority to hold and control the property, and who accepts or authorises acceptance of the certification agreement.
- An Agent is granted actual authority by the owner to register the project and accept the certification agreement.
- Where a project has multiple owners, GBCI asks that a single individual be identified to administer the certification process, supported by a Confirmation of Primary Owner's Authority Form.
In many cases the EDGE Expert serves as both Agent and Project Administrator — an expressly contemplated arrangement. What the Expert may never be is the Auditor or the Certifier on the same project.
The Auditor Engagement: Four Rules
This is the contract with the most examinable constraints.
- The client contracts the Auditor directly. GBCI states that you negotiate EDGE Auditor fees and contract terms directly with your chosen Auditor.
- Auditor fees are independent of GBCI fees. They are not part of the registration or certification fee and are not paid to GBCI. This is deliberate: paying the Auditor in local currency with minimal travel keeps audit costs proportionate to local markets.
- Only a listed Auditor may be used. GBCI states plainly that you may only use an EDGE Auditor listed on its published page.
- The contract must be in place before applying for certification. The Auditor engagement precedes the certification application, not the other way round.
Why the client pays the party auditing them
Candidates sometimes see a conflict here. The safeguard is not who pays but what the Auditor is contractually permitted to do:
- The Auditor must be independent of the developer, owner and project team.
- The Auditor does not influence project design or make recommendations, and becomes involved only once the project submission is received.
- The Auditor is prohibited from providing design or consulting services for the project they audit, and GBCI states the Auditor should not be viewed as a consultant.
- The Auditor recommends certification; the certifier decides, after its own quality review.
That last separation is the structural safeguard. An Auditor cannot issue a certificate, so a captured Auditor still cannot deliver one.
Firms Offering Both Services
A firm may hold both consultancy and audit capability — GBCI even operates an EDGE One-Stop Shop partner model. Two conditions apply, and both are contractual:
- The EDGE Auditor cannot provide any other services to a project they audit.
- The EDGE Auditor scope of work and associated fees must be listed separately from any other services provided by the firm — including EDGE Expert consultancy — on the proposal and on the contract.
A bundled line item reading "green building services — lump sum" breaches the second condition even if the individuals are genuinely different people. The separation must be visible on the paper the client signs.
The individual-level rule is absolute: a single individual may never hold more than one of the roles EDGE Expert, EDGE Auditor or EDGE Certifier in the context of a particular project.
The Expert Engagement
Engaging an EDGE Expert is highly recommended but not required. GBCI's reasoning is commercial rather than procedural: an experienced green building consultant quickly identifies the project's best path to meeting or exceeding the EDGE Standard, speeds up certification, and improves long-term return on investment by choosing strategies that perform without heavy maintenance.
Because the engagement is optional and unregulated as to fee, the Expert's own contract should state scope precisely — how many modelling iterations are included, who assembles evidence, who responds to audit queries, and what happens if value engineering forces re-modelling. Section 13.3 covers pricing; Section 14.3 covers why iteration count is the variable that most often blows an Expert's fee.
One Contract That Is Not the Project's
A point of confusion worth clearing: passing the EDGE Exam is not the end of becoming credentialed. Prometric's candidate bulletin notes that you provide your exam result to your EDGE local or global certifier in order to process your EDGE licensing agreement, and that the exam results without the EDGE licensing agreement do not qualify you for EDGE certification. The exam demonstrates competence; the licensing agreement makes you a credentialed professional in the system.
At what point in the process must a project have a contract in place with its EDGE Auditor?
A consultancy proposes to a client: "EDGE services — design advice, modelling and independent audit — one lump sum fee." What is wrong with this proposal?
A project team has clicked "Apply for Certification" in the EDGE App and selected GBCI as certifier, but has not yet returned the signed certification agreement or paid the invoice. What is the project’s status?
Is a project required to engage an EDGE Expert in order to pursue EDGE certification?
