GBCSA is the leading EDGE certifier in South Africa

GBCSA proudly offers EDGE (Excellence in Design for Greater Efficiencies) certification, a green building design tool, a certification system, and a global standard developed by the International Finance Corporation (IFC), a World Bank Group member. EDGE-certified projects reduce carbon emissions, save water, and lower living costs for occupants.

We certify EDGE projects throughout Africa.

What does it mean to be EDGE certified?​

To achieve an EDGE rating, a minimum saving of 20% in energy, water and embodied carbon in materials must be proven through initiatives implemented in the design phase and confirmed during construction.

When to Use EDGE Certification

EDGE Certification is ideal for various building typologies. Whether it's residential, commercial, hospitality, or retail, EDGE helps optimise your building's resource efficiency.

The Certification Process

The Certification Process

Appoint Your EDGE Professional Team

It's recommended to engage an EDGE Expert to guide your project from inception to completion, including document collation and submission for audit. An independent EDGE Auditor, separate from GBCSA, is required for the review of project documentation and verification of compliance with EDGE requirements before recommending the project for certification to GBCSA. Find qualified EDGE professionals in our GBCSA AP Directory.

Select the Appropriate EDGE Tool

Guided by your EDGE Expert, choose the EDGE Building Typology and Strategy that best aligns with your project. 

Register Your Project with GBCSA

When you have completed the self-assessment on the EDGE App to confirm that the minimum savings are achieved, you can begin the certification process by registering your project for EDGE certification with GBCSA via our website.

Project Documentation and Submission

Your EDGE Expert will manage project documentation and submit it to the EDGE Auditor, who in turn recommends the project for certification to GBCSA. The standard review and feedback process involves Round 1 (4 weeks) and Round 2 (3 weeks) at both the Preliminary and Post construction stages of the project.
