Construction Project GreenCard™ Certification Process
Construction Project GreenCard™ Certification Process Overview
The Construction Project GreenCard™ (CPG™) Certification Process is a structured sustainability assessment and verification pathway designed to evaluate construction projects across their lifecycle. The system is built around the Construction Work stages and assesses projects against seven sustainability categories with a total available score of 300 points. Certification is awarded based on verified performance at defined thresholds:
- Bronze: 150 to 199 points,
- Silver: 200 to 249 points, and
- Gold: 250 to 300 points.
CPG™ is designed as a two stage certification pathway. The first stage verifies the sustainability intent and technical readiness of the project at design stage. The second stage verifies actual implementation and as built performance after construction completion. This approach allows projects to demonstrate commitment early while ensuring that final certification is awarded only after evidence based verification.
The CPG™ Assessment Structure
The CPG™ framework assesses projects under seven major categories, totaling 300 points:
- Environmental (Env)
- Socio Economic (SoE)
- Energy Savings (EnS)
- Water Efficiency (WaE)
- Climate Resilience and Innovation (CRI)
- Technical and Performance (TeP)
- Eco Friendly Materials (EfM)
The assessment tool covers the full project lifecycle through the following stages:

Each criterion carries an allotted score, and many require documentary evidence, calculations, specifications, schedules, test reports, or other supporting uploads to validate project claims.
THE TWO STAGE CERTIFICATION PATHWAY
STAGE 1: DESIGN CERTIFICATION
Purpose
The purpose of Stage 1 is to confirm that the proposed design satisfies the CPG™ sustainability criteria and is on track to meet the targeted certification level. This is the design intent verification stage.
Process
- Project Registration
The project team registers through the CPG™ portal and gains access to the CPG™ application and rating tool. At this stage, the project information is entered, including project name, location, floor area, project type, and intended certification target. The project also begins populating the scorecard through the digital form.
- Appointment of a CPG™ Accredited Professional
The project team engages a Construction Project GreenCard™ Accredited Professional (CPG™ AP) to guide the certification process. The CPG™ AP supports the team in understanding the requirements, interpreting credits, preparing technical submissions, and coordinating evidence across the seven categories.
- Design Assessment and Documentation
Working with the CPG™ AP, the project team completes the design stage sections of the application and compiles all required supporting evidence. This may include sustainability strategies, design briefs, drawings, specifications, energy models, water calculations, material schedules, biodiversity studies, environmental assessments, and climate risk documentation depending on the credits pursued.
- Submission for Design Audit
Once the design package is complete, the documentation is submitted through the portal for review by the CPG™ Auditing Body. The submission includes the completed scorecard and uploaded evidence supporting the claimed points.
- Third Party Audit and Review
The CPG™ Auditing Body reviews the submission, verifies the evidence, and may issue clarification requests where additional explanation or documentation is needed. This stage ensures that the targeted points are substantiated and that the design has been assessed with integrity.
- Interim Design Certification
Where the submission satisfies the required threshold, the project is awarded an Interim CPG™ Design Certificate. This confirms that the proposed design has met the relevant sustainability criteria at design stage and allows the project to proceed to implementation with a verified sustainability direction.
STAGE 2: FINAL AS BUILT CERTIFICATION
Purpose
The purpose of Stage 2 is to verify that the constructed project has been delivered in line with the certified design intent and that the final installed measures, materials, systems, and operational readiness satisfy the applicable CPG™ requirements.
Process
- Construction Monitoring and Record Keeping
During construction, the project team maintains the documentation necessary to support final certification. This includes construction photographs, procurement records, commissioning reports, product data, material invoices, site logs, test results, and implementation evidence for the credits claimed. The CPG™ AP supports monitoring and helps keep the documentation aligned with certification requirements.
- Final Performance Verification Submission
After project completion, the team submits the as built documentation pack through the portal. This includes final evidence demonstrating what was actually delivered on site, such as commissioning reports, as built drawings, water and energy related calculations, indoor air quality and CO2 test results where applicable, handover records, and operational documentation.
- Final Audit and Site Verification
The CPG™ Auditing Body reviews the final submission and verifies the as built performance. The uploaded CPG process note states that mandatory site verification visits are undertaken by the auditor for a random sample of projects in order to confirm physical implementation and strengthen the credibility of the certification outcome.
- Final Scoring and Certification Award
Following audit completion, the final verified score is calculated from the approved evidence. Projects are then awarded one of the three certification levels:
- Bronze: 150 to 199 points
- Silver: 200 to 249 points
- Gold: 250 to 300 points
The published review duration for certification review is 28 working days.
Evidence Based Assessment
The CPG™ system is evidence led. Each assessment response must be supported with appropriate proof where required. Depending on the credit, evidence may include:
- Environmental Impact Assessment reports
- Biodiversity assessments
- Sustainability strategy documents
- Design briefs
- Energy models and simulation outputs
- Water efficiency calculations
- Material schedules and embodied carbon studies
- Commissioning plans and TAB records
- As built drawings
- IAQ and CO2 test data
- Stakeholder engagement reports
- Climate resilience documentation
- Handover and O&M manuals
This ensures that scoring is based on verifiable sustainability performance rather than declarations alone.
Key Features of the CPG™ Certification Process
1. Lifecycle Based Assessment
The process follows the project from strategic definition through in use performance, rather than concentrating only on the final building outcome.
2. Two Gate Verification
Projects are assessed first at design stage and then again at final as built stage, creating a robust control mechanism for sustainability delivery.
3. Accredited Professional Support
The process is supported by CPG™ Accredited Professionals, who help projects navigate technical requirements and prepare compliant submissions.
4. Independent Audit Integrity
Submissions are reviewed by a CPG™ Auditing Body, with clarification requests and random sample site verification forming part of the assurance framework.
5. African Context Relevance
The framework is positioned as a sustainability system tailored to local conditions, regulatory gaps, and implementation capacity, while still drawing from international standards and methodologies.
