EDGE Certification

EDGE is a measurable way for builders to optimize their designs, leading to a more investment-worthy and marketable product. By keeping certification fast and inexpensive, EDGE keeps pace with the momentum that developers need to stay at the forefront of the green building trend.

Edge keeps it simple. Simple, inexpensive, and effective.

EDGE was developed by the International Finance Corporation (IFC) in collaboration with the World Green Building Council to rapidly scale up the construction of green buildings. The certification provides a simple framework for building design and construction assessment. It asses buildings on three categories; energy use, water use, and embodied energy of materials. In South Africa the tool is currently only available for multi-unit residential developments.

Energy

The project building must use 20% less energy than the baseline using features throughout the thermal envelop, electrical, mechanical and water systems. This is calculated on an annual basis and compared in kWh/m2/year. .

Water

The project building must use 20% less water than the baseline using both supply side and demand side measures. This is calculated on an annual basis and compared in kL/m2/year.

Materials

This category assesses the embodied energy of the materials used in construction. Embodied energy accounts for the energy use in raw material extraction, processing, and transport. Again the project building must generate 20% less embodied energy of the materials than the baseline.

We encourage all projects considering EDGE certification to try out the online app. It is free to use, and it functions as a great design tool, accessible here: Edge Buildings.

If you are ready to certify your project and are looking for an auditor, or if you simply have more questions about the Edge process, please give us a call, or use the contact form.
