Why Green Mark for Interiors Version 1.2 matters now

The Singapore Green Building Council (SGBC) announced Green Mark for Interiors (GMI) Criteria Version 1.2 on 27 August 2026. The updated version applies to new applications from 2 September 2026, with supporting resources expected to be published around that date.

For building owners, tenants, fit-out teams and facility managers, the practical challenge is not only understanding the updated criteria. It is being able to produce reliable, traceable and clearly organised evidence when it is needed.

The circular highlights clarified documentation requirements, updated references to Singapore Standards including SS 553:2026 and SS 554:2026, revised energy-efficiency information, and expanded low-carbon scoring for existing mechanical and electrical systems and electrical appliances. These changes make evidence management an important part of Green Mark readiness.

AI does not replace the assessor, engineer, facilities team or responsible person. Used properly, it can help teams organise information, identify gaps and reduce avoidable submission errors.

What “audit-ready” evidence means

An audit-ready submission should allow a reviewer to understand:

  • What asset, space, system or activity the evidence relates to;
  • When the evidence was created, measured, inspected or approved;
  • Who provided or verified the information;
  • Which Green Mark requirement or supporting document it addresses;
  • Whether the document is current and complete; and
  • How the evidence can be traced back to the relevant site condition, drawing, record or measurement.

A folder containing hundreds of files is not necessarily a controlled evidence system. A better approach is to create a structured evidence register that connects each requirement to an owner, status, source document, review date and verification note.

A practical digital workflow for GMI Version 1.2

1. Start with an evidence and responsibility matrix

Translate the applicable GMI requirements into a working matrix before collecting documents. Depending on the project, the matrix may include interior materials, energy-related information, indoor environmental quality, low-carbon equipment, operational records, drawings, photographs, testing results and declarations.

Each line should have a clear evidence owner. For example, the fit-out contractor may provide product information, the M&E consultant may provide system details, the supplier may provide technical declarations, and the FM team may provide operating or maintenance records.

Useful fields include:

  • Requirement or evidence category;
  • Applicable space, asset or system;
  • Required document or data type;
  • Responsible person or organisation;
  • Submission status;
  • Document version and date;
  • Verification status;
  • Open issue or missing information; and
  • Final approval or sign-off record.

2. Build an interior asset register

Evidence becomes easier to manage when assets are consistently identified. Create a register for relevant interior and building-service assets, such as lighting, air-conditioning equipment, controls, electrical appliances, water fittings, finishes and other equipment relevant to the project scope.

Depending on the asset, useful fields may include location, equipment type, manufacturer, model, capacity, installation date, operating status, efficiency information, maintenance responsibility and supporting documents.

For existing M&E systems and electrical appliances, a structured register can help the project team distinguish between proposed upgrades, retained equipment and equipment that requires additional verification. This is particularly useful when low-carbon evidence depends on what is already installed and operating.

3. Connect documents to assets and locations

Do not rely on file names alone. A document management workflow should link each file to a project, floor, room, asset or evidence category. Drawings, photographs, invoices, product data sheets, commissioning records and maintenance documents should have consistent naming and version controls.

At a minimum, establish:

  • A standard naming convention;
  • One controlled location for current evidence;
  • Version and approval fields;
  • Document owners and review dates;
  • Rules for superseded documents; and
  • Access permissions for contractors, consultants, FM personnel and management.

This reduces the risk of submitting an old product sheet, an unapproved drawing or a document that cannot be matched to the installed condition.

4. Use sensors and operational data carefully

Where relevant, sensor and building-management-system data can support operational evidence. Examples may include temperature, humidity, carbon dioxide, equipment run status, energy-related readings or other indoor-environment and system-performance information.

However, data is only useful when its source and quality are understood. Record the sensor or meter identity, measurement period, location, unit, sampling frequency and any known data gaps. Establish who reviews abnormal values and how corrections are documented.

For smaller sites and SMEs, a full building-wide platform may not be necessary. A well-maintained spreadsheet, shared evidence register and controlled document repository can provide a practical starting point. The priority is traceability, not technology for its own sake.

5. Apply AI to review and workflow tasks

BCA identifies built-environment AI use cases such as knowledge management, AI-enhanced BIM, inspections, reporting and workflow automation. These applications can be adapted to Green Mark evidence preparation.

For example, an AI-assisted workflow may:

  • Read approved documents and extract model numbers, locations, dates and key technical fields;
  • Match documents to asset-register records;
  • Identify missing fields or inconsistent descriptions;
  • Compare a submission checklist against the evidence register;
  • Flag expired, duplicate or superseded documents;
  • Summarise inspection notes and identify unresolved actions; and
  • Prepare a draft evidence index for human review.

AI output should remain a review aid. A responsible person should confirm the extracted information, check that the evidence relates to the actual project and approve the final submission package. Sensitive drawings, contracts and operational data should also be managed with suitable access controls and retention policies.

How to reduce common submission problems

Many evidence issues are workflow problems rather than engineering problems. Typical examples include:

  • A product document that does not identify the installed model;
  • Photographs without location, date or asset references;
  • Energy or environmental data without a clear measurement period;
  • Conflicting equipment descriptions across drawings and schedules;
  • Incomplete records for retained or refurbished M&E systems;
  • Unclear ownership of missing documents; and
  • Last-minute collection of records from multiple contractors.

A monthly or milestone-based evidence review can expose these gaps earlier. Use a simple status such as not started, in progress, received, under verification, accepted or action required. Escalate missing evidence before handover, not just before submission.

Preparing for 2 September 2026

Teams preparing new applications should monitor SGBC’s official circulars and supporting resources as they are published. The final interpretation of any requirement should be based on the current official criteria, guidance and project-specific advice from the appointed professionals.

In the meantime, building owners and SMEs can take practical preparatory steps:

  1. Nominate a Green Mark evidence coordinator;
  2. List the project spaces, interior assets and retained systems within scope;
  3. Create an evidence matrix and document naming standard;
  4. Collect current drawings, schedules, product information and operating records;
  5. Check whether sensor, meter and inspection data can be traced to locations and assets;
  6. Run an AI-assisted completeness review on non-sensitive working documents; and
  7. Arrange an engineering or FM review of evidence before formal submission.

Where ISS can help

ISS supports businesses exploring engineering, facility management and AI automation requirements. A digital evidence workflow can be designed around the systems a site already uses, then improved through structured registers, document control, data extraction, checklists and human verification.

The objective is straightforward: make the right information easier to find, easier to validate and easier to explain. For Green Mark for Interiors Version 1.2, that discipline can help teams approach the 2 September 2026 transition with greater visibility and fewer avoidable evidence gaps.

Contact ISS to discuss your engineering, facility management or AI automation requirements.

Note: Green Mark requirements and supporting resources should be checked against the latest official SGBC and BCA publications and the requirements applicable to your project.
