  • Build your green building project into the EDGE App to start the certification process.

The free EDGE software offers a measurable way to cut back on the resource intensity of your building design.

The EDGE software can be used for free to design a resource-efficient commercial or residential building in 144 countries. Enter as much of your building information as you can, then choose systems and solutions and watch your savings grow. Discover the advantages of smart building design by pinpointing which options have the best results for the least cost.

The EDGE software calculates the utility savings and reduced carbon footprint of your green building against a base case. Your dashboard shows how much extra it costs to build green – and how short a time it takes to earn back the money through operational savings.

Reach the EDGE standard when your project hits 20 percent less energy, water and embodied energy in materials, and your project is ready for EDGE certification. See how you can model an energy-efficient building when you watch the demo.

As a smarter world plans for zero net carbon buildings, the EDGE software empowers industry leaders to achieve this aspiration.

For those who are highly motivated by environmental stewardship, the EDGE software now recognizes the procurement of offsite renewable energy and carbon offsets. EDGE also now reports the carbon footprint of all projects going forward. A new graph automatically appears in the energy section once a project has achieved 40 percent energy reduction, to estimate the purchase of renewable energy or carbon offsets required for a zero net carbon building. Through adoption of either strategy, an EDGE-certified project will be commended for carbon neutrality on its EDGE certificate.

The initiative is a result of close collaboration with Architecture 2030, the world’s leading think tank for encouraging architects to design climate-smart buildings, who believe that all new buildings and major renovations should be carbon neutral by 2030. The American Institute of ArchitectsWorld Green Building Council and the Global Alliance for Building and Construction have also expressed their support to help influence the adoption of zero net energy buildings wherever possible. In China, more than 50 architectural and planning firms have already pledged to design massive developments to either low-carbon or carbon-neutral standards.

Architecture 2030 references strategies recommended within the EDGE software through swatches in its 2030 Palette, an online resource for the design of zero net carbon buildings.

EDGE Makes it Easy


Beneath the interface is a powerful engine that understands local costs, climatic conditions and occupant behavior.


The ideal bundle of technical solutions can be discovered within minutes.


The EDGE software is free with certification available at a modest cost.


With EDGE, green buildings are suddenly available to all.

When resource efficiency is considered at the start, a metrics-driven approach delivers on the promise of optimized design.

The free EDGE software suggests defaults for your project’s base case. As selections are made, EDGE reveals performance through color-coded graphs.

Rather than suggesting the perfect scenario, EDGE encourages exploration. Receive instant feedback to see what works best for your building’s local climate to anchor your actions going forward.

While the 20 percent goal remains constant, the EDGE standard is contextualized to local regulations, costs and available materials. All of the complexity of the energy simulation analysis is hidden beneath the user interface, making it easy to see how much extra it costs to build green – and how short a time it takes to earn back the investment through operational savings.
