CERTIFICATION PROCESS

From first assessment to certification review, in 5 steps.

New-building certification progresses alongside design and construction. We align the work with these stages and define each deliverable at the outset.

Certification timeline and proposal scope

Why does certification follow construction?

New-building LEED certification requires evidence of both design and implementation. Construction completion, testing and final documentation determine when the review can proceed. One duration cannot apply to every project.

The proposal states which deliverable is due at each project stage. For existing buildings, we plan around the availability of operational data and required measurements.

Proposal: 2 working days. This is separate from the time required to complete certification.

Questions about green buildings

Before you decide.

Common questions about programme, scope and cost. A preliminary assessment helps us answer them for your project.

Let's evaluate your project together
How long does LEED certification take?

For a new building, LEED progresses alongside design and construction. Construction completion, required testing and documentation, followed by certification-body review, determine the outcome date. A single week or month range would therefore be misleading. Our proposal aligns consultancy deliverables with your project stages; we respond with a proposal within 2 working days.

The 5-step process ↗
What determines the cost of certification?

Consider four cost components: consultancy; certification-body registration and review fees; technical analysis such as energy modelling; and commissioning or performance testing where required. The proposal identifies which items are included. Certification bodies publish their fees on their official websites.

EDGE or LEED: which is right for my project?

Is resource efficiency the main priority, or do you need a broader environmental assessment? Consider the building type, intended scope and systems accepted by the client or finance provider.

Key benefitCompare resource-efficiency measures in one model.Document building performance across a broad set of credit categories.

Official system guidance: EDGE ↗ · LEED ↗

Can an existing building be certified?

Yes. LEED O+M provides a certification pathway for existing, operational buildings. We review the building’s use, operational data and eligibility to define the scope for initial certification or recertification.

How can certification support finance and leasing?

Certification presents building performance through evidence that others can assess. Consider its relevance in three areas:

  • Green finance

    Certification can document a finance product’s building-performance requirements. Confirm the accepted system and level with the finance provider at the outset.

  • Tenant and investor expectations

    It helps present requested environmental criteria, reports and building performance in a common assessment framework.

  • Operating costs

    Energy and water analysis helps identify improvement options. Actual savings depend on implementation, use and operating conditions.
