Green Star SA Rating System

Agreed standards and benchmarks for green building allow us to objectively assess just how “green” a building is. Rating systems provide a menu of green measures that can be used in the design, construction and management of a building to make it more sustainable.

There are several rating systems, including LEED from the US, BREEAM from the UK and Green Star from Australia. The Green Building Council SA uses the Green Star South Africa rating system, based on the Australian system and customised for the South African context.

Building owners submit documentation to the Green Building Council SA to achieve a Green Star SA rating. We employ independent assessors to evaluate submissions and allocate points based on the green measures that have been implemented. Certification is awarded for 4-Star, 5-Star or 6-Star Green Star SA ratings.

Green Star SA

The Green Building Council SA develops the Green Star SA rating tools to provide an objective measurement for green buildings in South Africa and to recognise and reward environmental leadership in the property industry.

Each Green Star SA rating tool reflects a different market sector including office, retail, multi-unit residential, public and education buildings, as well as others that are in development like interiors and existing buildings performance.

The objectives of Green Star SA tools are to:
• Establish a common language and standard of measurement for green buildings
• Promote integrated, whole-building design
• Raise awareness of the benefits of green building
• Recognise environmental leadership
• Reduce the environmental impact of development

You can be part of the development of Green Star SA rating tools by joining a technical working group or sponsoring a rating tool. Contact Tyrel Momberg ( to find out more regarding the New Build Rating tool V2



The GBCSA Net Zero/Net Positive Certification scheme will award projects which go beyond the partial reductions recognised in the current GBCSA tools, and have taken the initiative to reach the endpoint of completely neutralising or positively redressing their carbon emissions; water consumption; solid waste to landfill and their negative ecological impacts. The Scoping report is available here.
