A simple user-friendly Green Building Rating online software platform.

The EDGE (Excellence in Design for Greater Efficiencies) software is free and offers a measurable way to cut back on the resource intensity of your building.

The online platform quickly allows you to determine the financial viability of including green aspects on your projects. Its fast, affordable and makes sure green building is available for all. 

The EDGE standard is set at a minimum of 20% reduction across the following categories:

  1. Energy Consumption
  2. Water
  3. Embodied Energy

In order for EDGE to accurately calculate your buildings inputs and outputs it uses locally adjusted data across the following sets:

  1. Utility Costs
  2. Climate Data
  3. Building Regulations

How does EDGE work?

The GBCSA has partnered with the IFC and currently facilitates the certification using the EDGE-Homes tool. Simply register to use the EDGE online software for free here

Enter basic project information and the application will reveal how committing to a few practical energy and water saving options improves building performance at little or no cost.

EDGE will help you determine, at a concept level, the financial viability of a project’s green building initiatives early in the design stage.

Qualifying as an EDGE practitioner

Part of the registration process requires you to appoint and contract with an independent EDGE Auditor to compile all the necessary documentation for submission to the GBCSA. 

EDGE certificates are then issued to projects which successfully demonstrate they have met or exceeded the EDGE Standard at oth the Design and As Built stages of the project.
