Why I Like EDGE Certification a bit more than LEED: The Crucial Difference in Verification

When comparing LEED (Leadership in Energy and Environmental Design) and EDGE (Excellence in Design for Greater Efficiencies), both are highly regarded green building certification systems. However, one of the most significant reasons I prefer EDGE is its approach to documentation and verification. This often-overlooked aspect ensures that sustainability claims are not just made on paper but thoroughly verified and implemented in practice.

1. Verification of Documentation: Where EDGE Excels and LEED Falls Short

A longstanding concern in the sustainability community regarding LEED is its reliance on self-reported documentation. LEED certification is based on a point system, where project teams submit documents proving they have met certain sustainability criteria. However, LEED does not always verify whether these measures have been implemented on-site. This means that buildings may earn points for sustainability features that exist only on paper but are not truly executed.

In fact, studies have shown that 10-20% of LEED-certified buildings might not fully meet the sustainability standards they claim, primarily due to this lack of rigorous verification

This can lead to cases of greenwashing, where buildings are presented as sustainable without fully implementing the required measures.

On the other hand, EDGE's process ensures accountability. Not only must developers submit documentation, but third-party verification is required. Independent auditors visit the project site to confirm that the sustainability measures described in the documentation are actually in place. This includes verifying energy-saving technologies, water-efficiency systems, and the use of sustainable materials.

EDGE’s rigorous verification process significantly reduces the chances of greenwashing and gives confidence to developers, investors, and stakeholders that the building truly meets its sustainability goals.

Why This Verification Process Matters

The difference in documentation approaches is critical, particularly in today's world where transparency and accountability are essential in the fight against climate change. By requiring a third-party auditor to verify that sustainability measures are in place on-site, EDGE guarantees that buildings are not only designed with sustainability in mind but that these designs are realized in practice.

This process is particularly important for:

• Investors, who need assurance that their funds are being used for genuinely sustainable projects.
• Building owners, who want confidence that their buildings operate efficiently and sustainably.
• Governments and regulators, who use green certifications to approve projects or award incentives.

Conclusion: EDGE's Verification Process Makes It a Better Choice

For those of us working in sustainability, ensuring that the promises we make are fulfilled is crucial. EDGE’s third-party verification process offers confidence that what is documented will actually be implemented on-site. While LEED offers a broader certification system, its reliance on self-reported documentation leaves room for potential misrepresentation or incomplete implementation.

In my experience, EDGE’s commitment to accountability through rigorous on-site audits is one of the key reasons I prefer it over LEED. It ensures that sustainability goals are not only promised but also delivered, making it a more reliable and trustworthy choice for projects that aim to genuinely reduce their environmental impact.
