Learn the differences between EDGE, EDGE Advanced, and EDGE Zero Carbon, discover when each certification applies, and see how they can improve efficiency, reduce carbon emissions, and increase the value of real estate developments.
Sustainable construction is evolving rapidly. A few years ago, the main goal was to reduce energy and water consumption in buildings. Today, the market increasingly expects projects to significantly lower their carbon footprint and align with global decarbonization commitments.
In this context, EDGE certification has expanded its scope through two higher performance levels that respond to the sector’s new demands: EDGE Advanced and EDGE Zero Carbon.
These certifications allow developers, investors, and property owners to demonstrate stronger environmental performance, access better financing opportunities, and increase the value of their real estate assets.
But what exactly do these certifications mean, and when does it make sense to pursue each one?
In this article, we explain the differences between EDGE, EDGE Advanced, and EDGE Zero Carbon, their requirements, benefits, and how to choose the most appropriate option for a project.
EDGE certification (Excellence in Design for Greater Efficiencies) was developed by the International Finance Corporation (IFC), a member of the World Bank Group, to make sustainable construction more accessible through a simple and measurable methodology.
To obtain EDGE certification, a project must demonstrate at least:
These three indicators have made EDGE one of the most widely used sustainable building certifications in emerging markets, especially across Latin America.
EDGE Advanced represents a higher level within the EDGE certification system.
It was created to recognize projects that achieve substantially better energy performance than the standard EDGE requirements.
To obtain EDGE Advanced certification, a building must demonstrate:
This level responds to the growing demand for high-performance, energy-efficient buildings.
EDGE Zero Carbon represents the highest level within the EDGE system.
In addition to meeting EDGE Advanced requirements, the project must offset or eliminate its operational carbon emissions through renewable energy or other equivalent mechanisms recognized by the program.
The objective is for the building to operate with net operational carbon emissions close to zero.
EDGE Zero Carbon responds to the need to accelerate the transition toward decarbonized buildings that align with international climate goals.
Although all three certifications belong to the same system, each one addresses a different level of ambition.
EDGE is designed for projects seeking a significant improvement in efficiency through minimum reductions of 20% in energy, water, and embodied energy in materials.
It is an excellent option for developments beginning their sustainable construction strategy.
EDGE Advanced is designed for buildings seeking superior energy performance.
It requires at least 40% energy savings, representing a more ambitious level of efficiency.
EDGE Zero Carbon is the most advanced level of the system.
In addition to high energy performance, it requires the building to operate with net operational carbon emissions close to zero through renewable energy or recognized offsets.
EDGE Advanced is often the most suitable option for projects that:
It can be especially relevant for corporate offices, hotels, hospitals, and large-scale developments.
EDGE Zero Carbon is particularly relevant for organizations with clear decarbonization targets.
It may be appropriate for:
An increasing number of investors view this type of certification as an indicator of resilience and long-term competitiveness.
Moving toward these higher certification levels provides benefits that go beyond resource savings.
Key advantages include:
These benefits can support both financial performance and long-term market positioning.
EDGE Advanced and EDGE Zero Carbon can apply to multiple building typologies, including:
Eligibility depends on the project design, the efficiency strategies implemented, and the ability to meet the technical requirements.
Energy efficiency is the main differentiator among the EDGE certification levels.
Projects pursuing EDGE Advanced and EDGE Zero Carbon often incorporate strategies such as:
These measures reduce both operational energy consumption and the carbon emissions associated with building use.
More organizations are incorporating ESG objectives into their corporate strategies.
EDGE certifications provide a way to demonstrate measurable environmental results through verified indicators related to:
This can strengthen relationships with investors, financial institutions, and other stakeholders.
The right decision depends on factors such as:
Conducting a technical assessment during the early stages of the project makes it possible to identify which certification level offers the best balance between performance, investment, and return.
At Leaf Global, we support developers, investors, architects, and companies throughout the EDGE certification process.
Our team helps clients:
Our objective is to help each project achieve the certification level that best aligns with its business, sustainability, and profitability goals.
Sustainability is no longer only about consuming fewer resources. Today, the market expects buildings to reduce emissions, improve efficiency, and respond to the challenges of climate change.
EDGE Advanced and EDGE Zero Carbon represent the natural evolution of EDGE certification for projects that want to go beyond minimum requirements and position themselves as leaders in sustainable construction.
The right level will depend on each project’s strategy, but in every case it represents an opportunity to increase asset value, strengthen ESG credentials, and respond to the expectations of investors, users, and financial institutions in an increasingly competitive real estate market.
