Our proposals are all-inclusive. That means they cover everything related to your EDGE certification journey, including registration, preliminary and final certification costs, design audit fees (if applicable), and site audit fees. We also include a standard scope of EDGE Expert support at no additional cost to help you get started with your EDGE journey.

The first step to getting your project registered is to ensure your registration invoice has been paid. Once payment has been received, your auditor will contact you and ask you to submit the project on the EDGE App for registration. Make sure you select “Sintali-SGS” as the certifier.

Registration, certification and design audit fees need to be paid upfront before any work starts, to avoid any conflict of interest. As soon as payment is received, the project is registered on the EDGE App. For portfolio projects, payment plans are arranged accordingly.

The time needed for EDGE certification depends largely on the availability of documentation and the client’s familiarity with the EDGE App and the process. Typically, EDGE certification and audit can take a matter of weeks. If you are working towards a specific deadline, for example accessing financing or a live event, please let us know as early as possible so we can help you meet your deadline.


We currently only offer live stream EDGE Expert Training in English, but we are working on offering courses in other languages soon

Head to the EDGE app and create the first use of your subproject. Using the same project name, create another subproject with the second use and save it. You can do this for as many uses as you have in your project. Make sure to be signed in to be able to save or the save function won’t work.

  1. Measure entire “exterior” wall length – the line that separates “interior” from “exterior” (red line)
  2. Ignore small details: ducts, notches
  3. Multiply by floor height =Wall Area
  4. Sum the area of all glazed windows and doors = Window Area
  5. Divide Window Area by Wall Area = WWR


Tip: Include walls with windows into unconditioned enclosed space.

If you have two cooling systems, select the measure representing the system with the biggest capacity and model the remaining systems in the calculations of this measure. For example, a project has:

  1. 200 Refrigeration Tons (RT) air-cooled chiller
  2. 50 RT water-cooled chiller
  3. 48000 BTU/h VRF system

Select “Air Conditioning with Air Cooled Chiller” in this case and include all the systems in the calculations of that measure (preferably using the EDGE calculator of that measure). Make sure to convert all cooling capacities to the same unit when comparing system capacity.

Yes, as long as the efficacy of the lighting is above 90 Lumens/Watts. At least 90 percent of all the fixtures must meet the EDGE requirements. You can still pursue the lighting measures even if not 100 percent of your lighting fixtures are EDGE compliant.

Please refer to the Materials User Guide and select a material that has similar/comparable embodied energy on the EDGE app.
