1.2 The WELL Certification Journey & Documentation

1.2 The WELL Certification Journey & Documentation

Quick Answer: The WELL certification process follows a structured sequence: Registration on the WELL digital platform, Documentation Submission and Review (Preliminary and Final), on-site Performance Verification, Report Issuance, and Certification Award. Verification relies on four foundational document types—Design Specifications, Operations Schedules, Policy Documents, and professional Letters of Assurance (LOAs)—backed by GBCI oversight and formal curative protocols.

Earning WELL Certification requires more than good intentions; it demands an organized, multidisciplinary workflow that unites architects, mechanical engineers, contractors, facilities directors, human resources executives, and property owners. The certification journey translates health concepts into audited design features, operational practices, and physically verified environmental parameters.

Phase 1: Project Registration

The project team registers on the WELL Digital Platform (projects.wellcertified.com), the official online registration and project-management system. A project is officially registered only once the registration invoice has been cleared. At registration the team may elect either single-cycle certification or activate a three-year or five-year subscription (WELL v2 only); subscriptions include recertification and optional annual mid-cycle reviews for additional features.

• What must be identified at registration: the project boundary and project area, and — for WELL Core projects only — the WELL Core designation itself. All other WELL v2 projects do not register under a specific project type; the platform recommends a scorecard based on the space types present, and the team can add or subtract features up until documentation submission.
• Addenda lock-in: the quarterly addenda version of WELL current at enrollment applies for the life of the project unless the team chooses to update to a newer addenda.
• Registration expiry: WELL v2 projects must undertake performance-testing measurements within five years of registration (or while the subscription is active, whichever is longer), or registration expires. Extension requests must be made at least one year before expiration.

Phase 2: Documentation Preparation & Scorecard Management

The project team selects the target preconditions and optimizations on their digital scorecard. Over several months of design and pre-occupancy planning, the team gathers required drawings, specifications, operations schedules, corporate policies, and signed Letters of Assurance.

Phase 3: Preliminary Documentation Review

Once all documents are uploaded, the Project Administrator submits the package to GBCI for Preliminary Documentation Review.

• Timeline: GBCI completes its technical review within 20 to 25 business days.
• Review Outcome: GBCI returns a preliminary review report indicating which features are verified, which require additional clarification, and which are deemed non-compliant.

Phase 4: Final Documentation Review

The project team responds to GBCI's comments, providing amended drawings, expanded policies, or clarified calculations.

• Timeline: GBCI conducts the Final Documentation Review within 20 to 25 business days.
• Milestone: Approval of the Final Documentation Review establishes that all design, specification, policy, and operations features are formally accepted, clearing the project for on-site testing.

Phase 5: Performance Verification Eligibility

The WELL Certification Guidebook sets four eligibility conditions, and which ones apply depends on the project path — a classic exam distinction:

• For WELL Core, "construction complete" refers to the base building. Interiors need not be complete, though active interior construction will likely degrade test results.
• Coworking spaces may satisfy the occupancy condition either through 50% of total expected occupancy (including tenants or members) or 100% of coworking management staff.
• For WELL Core, at least 2.5% of total building floor area must be available for testing, and it must include all common areas and spaces under building-management control; if that is under 2.5%, the project supplements with tenant space.

Phase 6: Performance Verification (On-Site Testing)

An independent, GBCI-accredited WELL Performance Testing Agent (PTA) arrives on site to execute environmental sampling, acoustical measurements, lighting sweeps, and visual inspections according to rigorous scientific protocols.

Phase 7: The WELL Report

The WELL Performance Testing Agent transmits both analyzed results and raw data to GBCI in the format prescribed by the Performance Verification Guidebook. The WELL Reviewer evaluates the data against WELL thresholds and issues the WELL report — a feature-by-feature assessment of whether each pursued feature was approved. The turnaround depends on who tested:

• 40–45 business days from completion of performance testing when GBCI is the WELL Performance Testing Organization.
• 20–25 business days from submission of results when the project engages a non-GBCI WELL Performance Testing Agent.
• If GBCI needs more information about on-site conditions, that triggers a second round of review requiring a further 20–25 business days.

Note that performance testing routinely involves third-party laboratory analysis for radon, formaldehyde, VOCs and up to 32 different water contaminants, so lab turnaround, damaged samples or out-of-tolerance results can extend the timeline.

Phase 8 & 9: Accept, Cure or Appeal — then Award

Once the WELL report is issued, the project owner has 180 calendar days to do exactly one of three things: accept the report on the WELL Digital Platform, initiate a curative action, or file an appeal. If none of these happens within 180 calendar days, the project is deemed to have accepted the report as final. A passing report yields the certification level stated in the report; certified projects then move into the annual-submission cycle.

2. The WELL Digital Platform & Key Team Roles

The WELL digital platform is a dynamic cloud-based portal that acts as the single source of truth for every registered project. It hosts the interactive scorecard, coordinates document uploads, logs real-time sensor streams, and facilitates communication with GBCI review staff.

3. The Four Core Documentation Types

To earn feature verification, project teams submit rigorous documentation. WELL v2 groups required documentation into four distinct categories:

+-----------------------------------------------------------------------------------+
|                             THE 4 DOCUMENTATION TYPES                             |
+-----------------------+-----------------------+-------------------+---------------+
| 1. Design Specs &     | 2. Operations &       | 3. Policy &       | 4. Letters of |
|    Drawings           |    Maintenance Logs   |    Programs       |    Assurance  |
+-----------------------+-----------------------+-------------------+---------------+
| • Stamped MEP plans   | • Green cleaning plan | • Employee HR     | • Architect   |
| • Finish schedules    | • Filter replacement  |   handbooks       | • MEP Eng     |
| • Equipment cuts      | • Water flush logs    | • Wellness ben.   | • Contractor  |
| • Architectural plans | • Legionella plan     | • Leave policies  | • Owner       |
+-----------------------+-----------------------+-------------------+---------------+

1. Design Specifications & Architectural Drawings

These documents demonstrate that physical infrastructure, spatial geometry, and technical hardware meet WELL criteria:

• Stamped mechanical engineering floor plans showing ventilation duct routing, outdoor air CFM delivery rates, and thermal zoning boundaries.
• Reflected ceiling plans (RCPs) displaying lighting fixture layouts and emergency exit paths.
• Cut sheets and submittals for air handling units, media filters at the A12 level required by outdoor $PM_{2.5}$ (MERV 12, 14 or 16) and activated carbon filters where A13 is pursued, point-of-use water treatment devices, and height-adjustable workstations.
• Architectural finish schedules verifying low-VOC paints, adhesives, and flooring.

2. Operations Schedules & Maintenance Policies

These documents confirm that ongoing building operations maintain human health over time:

• Standard Operating Procedures (SOPs) for building maintenance and green cleaning protocols adhering to EcoLogo, Green Seal, or EPA Safer Choice standards.
• Preventive maintenance schedules showing filter inspection and change-out cycles.
• The W03 Legionella management plan, with its seven required elements. WELL does not mandate a named external standard here, though most plans are built on ASHRAE Standard 188 and Guideline 12, whose structure maps closely onto W03's elements.
• Cleaning chemical inventories and pest management logs (Integrated Pest Management - IPM).

3. Policy and Program Documents

Many features in the Nourishment, Mind, and Community concepts pertain to organizational behavior and human resource policies:

• Corporate employee handbooks outlining paid parental leave policies against C08's tiers — 12, 18 or 30 weeks paid primary caregiver leave paired with 2, 3 or 4 weeks paid non-primary caregiver leave.
• Health and wellness benefit documentation detailing Employee Assistance Programs (EAP), mental health screening access, and subsidized gym memberships.
• Dietary and catering policies establishing bans on artificial trans fats and limits on sugar-sweetened beverages in cafeterias and meeting rooms.
• Emergency management, crisis communication plans, and occupant emergency response manuals.

4. Letters of Assurance (LOAs)

Letters of Assurance are legally binding, signed declarations provided by licensed project professionals confirming compliance with technical features that cannot be easily verified through visual plans alone:

• Licensed Architect: Confirms spatial layouts, ceiling heights, biophilic design elements, and active staircase visibility.
• Mechanical / Professional Engineer (PE): Verifies outdoor ventilation air delivery per ASHRAE 62.1, filtration bypass prevention, acoustic mechanical noise isolation, and thermal comfort setpoints.
• General Contractor (GC): Confirms that A04 construction pollution management was executed — ducts sealed or cleaned before registers were installed, MERV 8 return-air filters used if the permanent system ran and replaced before occupancy, absorptive materials stored separately and protected from moisture, work areas isolated, walk-off mats in use and dust guards on saws — and that specified low-chemical materials were installed without unauthorized substitutions.
• Project Owner: Attests to organizational commitments, non-retaliation policies, and operational maintenance funding.

4. Clarifications, Curative Actions & Appeals

During the review process, projects may encounter non-compliance findings or ambiguous evidence. WELL provides clear administrative mechanisms to resolve these issues:

Mid Review Clarifications (MRCs)

If, during a round of review, the WELL Reviewer finds a submission inaccurate or needs clarification, they issue a Mid Review Clarification (MRC). The WELL team has a 30-business-day window to amend existing documents or submit additional materials in response. Supplying supplementary evidence, revised calculations or explanatory narratives at this stage costs the project nothing and forfeits no features.

Alternative Adherence Paths (AAPs) in the review workflow

An AAP proposes an alternative strategy for meeting the intent of an existing feature, and its administrative rules are heavily tested:

• Each AAP pertains to one feature, and only one AAP per feature part may be under review at a time. There is no cap on the total number submitted.
• AAPs must be submitted as part of or prior to final documentation submission. An AAP submitted after the final documentation report is returned is treated as an appeal.
• Free allowance: three free AAPs for WELL v1 and WELL v2 projects; ten free AAPs for WELL v1 pilots, WELL v2 pilot and all WELL subscribers. Additional AAPs cost a fee.
• Up to three AAPs may be submitted before registration, and those rulings may be used after registration (they still count against the project's free allowance).
• The ruling is posted to the WELL Digital Platform within 10–15 business days; an MRC pauses the clock and the ruling then follows within ten business days of the response.
• A project may retract an AAP without it counting against the free allowance if the request reaches the WELL coaching contact within 48 hours of submission.

Curative Action Plans

If a project fails an on-site environmental test during Performance Verification (for instance, if ambient $PM_{2.5}$ exceeds $15\ \mu\text{g/m}^3$ or coliforms are detected in a water sample), certification is withheld until the failure is cured.

• A curative action plan must be submitted within 180 calendar days after issuance of the WELL report, outlining the steps to address each unmet feature.
• The WELL Reviewer evaluates the plan and returns results within 20–25 business days. Only after the plan is accepted does the project enact the fix and schedule re-testing.
• Watch for cross-feature side effects: the guidebook's own example is a project that fixes a microorganism failure by adding chlorine and thereby risks exceeding the chlorine limit in another feature.
• Re-testing may be performed by the original WELL PTA or a different one, and may be repeated for additional fees if the first round of re-testing still fails.

The Formal Appeal Process

If a project team disagrees with a finding in the Documentation Review or Performance Review, it may file an appeal (for a fee) — and appeals may also be used to submit new features for review:

• Scope: each appeal applies to one feature; a separate appeal is required per contested feature.
• Timeline: all appeals must be submitted within 180 calendar days after the date the WELL report is issued.
• Response: GBCI returns an appeal review report within 20–25 business days. While an appeal is open, the project is considered to be in the Documentation Review stage for purposes of scheduling Performance Verification.
• One more bite: a project is limited to one subsequent appeal per feature, which must be submitted within 90 calendar days of the issuance of the appeal review report.
