Frequently Asked Questions​

Most frequent questions and answers


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. If you selected EDGE Expert support, that is also included in the proposal.

You cannot choose your auditor. Sintali works exclusively with SGS. We offer a one-stop shop approach, so you get one contract that includes the certification and auditing, without having to negotiate or tender your auditing fees separately. SGS is one of the largest global auditing firms in the world and has auditors around the world. Having worked on hundreds of EDGE projects, they bring high quality, rigor and expertise to our clients.

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.

EDGE Certification

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. From the point that an audit is submitted to the certifier for review, it takes approximately 4 weeks. We do offer an expedited review service for an additional cost. 

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.

To achieve EDGE Zero Carbon Certification, a project must reach a minimum of 20 percent savings in water and embodied energy, and a minimum of 40 percent energy savings on-site. 100 percent energy savings can then be achieved either through renewables or carbon offsets. For more information, read the IFC guidance.

EDGE certificates do not need renewals as they certify that the asset is built to be resource-efficient.

Projects that undergo the EDGE Zero Carbon certification require renewal every 2-4 years as the certification is based on operational data.

Version 3.0

One of the key updates in EDGE version 3.0 is an updating of all the baselines around the world. As building codes become more rigorous, the baselines in EDGE become more rigorous as they are an aggregation of building codes and industry practices. That means that countries where the building regulations have become more stringent will see that a 20% improvement over the baseline is harder to achieve than it used to be.

The EDGE App is owned and managed by IFC. As certifiers, we can submit errors to IFC to be resolved, but we do not have direct control over the EDGE App. Please submit the error to with screenshots and we will work with IFC to resolve the issue.
