EDGE is a tool to estimate the resource use of buildings already during the planning phase and awards projects that save resources. The cloud-based platform has a sophisticated set of city-based climate and cost data, consumption patterns and algorithms for predicting the most accurate performance results. On this basis, the tool calculates additional costs to build green and how long it takes to earn back the money through operational savings. With EDGE, the IFC aims to deliver a solution to prove the business case for building green and unlock financial investment. Based on the performance, buildings can receive a certification.

Tool Outcome

Depending on the resource savings, EDGE offers three different certification levels:
– EDGE Certified (savings of at least 20 % across all three resource categories)
– EDGE Advanced (on-site energy savings of at least 40 %)
– Zero Carbon (buildings based on 100 % renewable energy or purchased carbon offsets to top off at 100 %)

Sustainability Criteria

The tool measures resource savings in three areas:
– Water
– Energy
– Energy embodied in materials
