Designed for emerging markets, EDGE offers a faster, easier, and more affordable approach to certification than was previously available. It consists of free design software, a streamlined online certification system, and the world’s
largest network of certifiers.
EDGE’s software allows a user to apply different systems, solutions, and design techniques to discover the most cost-effective way to design and build green. These include energy-efficient lighting and cooling, shading, natural ventilation, and low-flow water fixtures, which help optimize building performance. Incremental capital costs are indicated with the payback period, as well as the value that is transferred to future owners of the property. The software is calibrated to take local conditions into account, including climate and local industry costs and practice. EDGE is available in over 150 countries for residential, public, and commercial projects.
In September 2019, EDGE launched two new certification products to recognize highperforming projects:
• EDGE Advanced: Awarded to projects that improve energy efficiency by 40 percent or more, in addition to at least 20 percent savings in water and materials as per EDGE certification requirements.
• EDGE Zero Carbon: EDGE Advanced projects that achieve 100 percent carbon neutrality through renewables or carbon offsets at the operational stage receive further distinction.
EDGE is the only system that requires efficiency in embodied energy in materials as a certification parameter. To better address the issue of embodied carbon in construction materials, IFC is exploring moving from requiring a minimum of 20 percent efficiency in embodied energy in materials to embodied carbon in materials.
