EDGE - Residential

Use our simple user friendly online platform to rate you residential development.

EDGE-Residential offers developers, financiers, investors and other key collaborators the opportunity to meet the expectations of progressive consumers who want to save money while living in energy and water efficient spaces.

Projects built to the EDGE standard deliver carbon emissions reductions, water savings and a lower cost of living as well as attract new customers, promote brand interest and secure distinction in the marketplace. 

How does this tool work?

EDGE certification involves two key stages. It is recommended that a project go through both preliminary and post construction stages in order to successfully achieve EDGE certification. 

Each stage consists of a 2 round submission process to the GBCSA

1. Preliminary:  At the design stage, enter the project details into the EDGE software and select green options.  The platform will quickly establish the feasibility of the green measures you plan to use on the project. 

Note: In order to comply, the project must reach the EDGE Standard of a minimum of 20% improvement in energy, water, and embodied energy in materials as measured against current standard building regulations.

A preliminary certificate is issued by the GBCSA at this stage.

2. Post Construction: Following construction an EDGE auditor is dispatched to site to verify the projects green credentials. The EDGE auditor will then collate the findings and submit the relevant documentation to the GBCSA. 

The GBCSA will then verify the documentation and issue a final EDGE certification certificate per unit to the project owner.

Taking green measures, EDGE proves that the next generation of buildings can be more affordable to build. Preliminary indications from South African pilot projects targeting EDGE certification point to an additional construction cost of not more than 3% to meet the EDGE Standard, but this will vary for each project depending on the specific design of the project.

An independent EDGE Auditor must be appointed by the project developer at market related rates to collate and submit the documents to GBCSA for review and certification. 

EDGE Auditor are third-party professionals whose fees will be directly negotiated with the project developers and not set by GBCSA.

The correct rating tool needs to selected in order to rate the project. 

To comply, the project must reach the EDGE Standard of a 20% improvement in energy, water, and embodied energy in materials as measured against current standard building regulations.

Find the right EDGE tool

You or your selected EDGE Auditor will enter the project details into the EDGE software and select green options.

Register your project

Project documents are reviewed and submitted by the EDGE Auditor to the GBCSA.

Register your project

The GBCSA reviews and provides feedback on project documentation. If the minimum 20% Standard is achieved on all three categories, the GBCSA will issue a preliminary design certificate (that will expire in two years’ time from this date).

Round 2 allows for EDGE practitioners and building owners to provide more information or make limited amendments to their submission.

A certificate is issued to each certified project for both preliminary and post construction phases in order to publicly display your hard work!
