Bentley Systems announce integration of EC3 with Bentley iTwin platform at COP27


Expanded integrated workflows for embodied carbon computation in the Bentley iTwin platform have been announced by Bentley Systems. With the help of the Embodied Carbon in Construction Calculator, the new integration enables carbon assessment in digital twin solutions for infrastructure (EC3).


Building Transparency offers the knowledge, materials, and techniques - such as EC3 - to address the role of embodied carbon in climate change. Construction material suppliers and manufacturers are being encouraged to invest in disclosure, transparency, and material innovations that lower the carbon emissions of their products as a result of the EC3 tool and its subsequent impact on the industry. These actions are driving demand for low-carbon solutions.


EC3, a free, open-access tool created by the nonprofit Building Transparency, enables benchmarking, assessment, and embodied carbon reductions with a focus on the initial supply chain emissions of construction materials.

Construction material suppliers and manufacturers are being encouraged to invest in disclosure, transparency, and material innovations that lower the carbon emissions of their products as a result of the EC3 tool and its subsequent impact on the industry. These actions are driving demand for low-carbon solutions.


The EC3 integration enables the free, open-source EC3 carbon database and calculator, Bentley's infrastructure digital twin solutions powered by iTwin, and third-party applications built on the Bentley iTwin platform, to simplify and accelerate the generation of carbon reporting and insights. The Bentley iTwin platform is an open, scalable platform-as-a-service that gives developers the tools they need to build and market products that use digital twins to address actual infrastructure issues.


Designers and sustainability engineers in the architectural, engineering, and construction sectors devote a significant amount of time to manually exporting and compiling data from quantity counts and bills of materials in order to evaluate or report on the environmental impact of infrastructure projects. It may also be prone to errors, necessitating further assurance of successful carbon tool intake. Additionally, AEC professionals don't want to be restricted to using a single carbon calculator because different calculators may produce different results (for example, due to uncertainties in environmental product declarations), and the requirements for carbon reporting and certification vary depending on the project, the country, or the owner of the infrastructure.

Due to Building Transparency's open-source/open-access approach, the additional integration with EC3 not only improves accuracy while reducing time, but also offers uncertainty assessments of the EPD data and raises carbon transparency. Using the Bentley iTwin platform, users may combine engineering data produced by diverse design programs into a single perspective, produce a uniform report of materials and quantities, and share it via cloud synchronization with various carbon analysis systems, including now EC3.


WSP, which uses both the Bentley iTwin platform and the EC3 database on infrastructure projects like as the Interstate Bridge Replacement program, is one of the shared users with an interest in this new connection. According to Thomas Coleman, vice president of WSP USA, "for WSP, carbon footprint analysis and reduction are crucial in planning, designing, building, and running an infrastructure project from beginning to end." Better iTwin interaction with EC3 is a game-changer for us on a number of infrastructure projects, according to the author. The time and money required to provide detailed embodied carbon analyses and reports along the design and construction stages will be greatly decreased by implementing this relationship. In the long run, we see this collaboration as another step toward open, always-updatable digital twins of infrastructure, where carbon calculation and optimization are inherent and transparent in all phases of the infrastructure lifecycle across the entire value chain.
