EDGE Green Building Certification South Africa

Globalisation and rapid urbanisation are taking over cities across the world, which is resulting in threatened infrastructure, energy shortages, waste accumulation, water insecurity and air pollution to name a few. The need for greener, more sustainable buildings to combat the ill effects of such growth, however, is increasing. Through green building tools such as EDGE, buildings can be transformed into change agents and help combat greenhouse gas emissions, carbon footprints and better the communities around them through greener design considerations.

What is EDGE?

EDGE, which stands for Excellence in Design for Greater Efficiencies, is a Green Building Rating tool that is focused on increasing the resource efficiency for several building types, especially in the context of homes and large-scale residential buildings in South Africa. The certification requires achieving a minimum saving of 20% in the three categories: operational energy, water usage and reduction in embodied energy.


The EDGE certification results in residential developments that are:
