Why certify your building?

Better health & well-being

Green certified projects must be designed to be healthy and comfortable spaces, aware of the community in and around them, and promote the wellbeing and productivity of their users.

Better resilience

Certified green projects use less vital resources like electricity and water, resulting in lower operating costs, and contributing their part to climate change mitigation in South Africa.
