Bentley Systems announces integration of EC3 with the Bentley iTwin Infrastructure Carbon Calculation Platform

Ability to calculate, report and analyze embedded carbon in infrastructure digital twins at no additional cost

Bentley Systems, Incorporated (Nasdaq: BSY), the infrastructure engineering software company, announced comprehensive integrated workflows for embedded carbon calculations in the Bentley iTwin platform at COP27. The new integration enables CO2 assessment in Digital Twin infrastructure solutions, supported by the Embodied Carbon in Construction Calculator (EC3). EC3, developed by the non-profit Building Transparency, is a free and freely available embedded carbon benchmarking, assessment and reduction tool targeting building material emissions in the supply chain. Building Transparency provides knowledge, resources and tools – including EC3 – to address the role of embedded carbon in climate change. The EC3 tool and its impact on industry is driving demand for low-carbon solutions and encouraging building material manufacturers and suppliers to invest in disclosure, transparency and material innovations that reduce the carbon emissions of their products.

Rodrigo Fernandes, Bentley’s director of ES(D)G – Empowering Sustainable Development Goals – said: “This new integration into Bentley’s infrastructure digital twin platform exemplifies our strategy to empower our users to achieve sustainable development goals. EC3 from Building Transparency is a perfect example of targeted open collaboration in the ecosystem, where the private sector can come together to support and accelerate climate action.”

Stacy Smedley, Managing Director of Building Transparency, said: “We are delighted to now be part of the Bentley iTwin platform ecosystem. It is fantastic that the integration is built on an open source framework – which is the foundation of both EC3 and iTwin platform, we see this integrated workflow as an important opportunity for AEC companies, ISVs and digital integrators to connect carbon analytics to digital twins to infrastructure while ensuring full control over their data, applications and intellectual property.”

The EC3 integration enables Bentley’s digital twin infrastructure solutions, powered by iTwin, and third-party applications built on the Bentley iTwin platform to generate CO2 reports and insights based on the free open source EC3, which simplifies and accelerates CO2 database and calculation. The Bentley iTwin platform is an open, scalable platform-as-a-service offering that enables developers to create and market solutions that solve real-world infrastructure problems by leveraging digital twins.

Kaustubh Page, director of product management, iTwin platform for Bentley Systems, said: “We see the EC3 integration as an essential feature of the Bentley iTwin platform, moving us further towards the sustainability vision of the platform. We are pleased that our users are leveraging our Carbon Calculation Service on the Bentley iTwin platform to realize carbon workflows such as reporting, project selection and material selection optimization. We are pleased to integrate an additional life cycle assessment tool to unlock decarbonisation workflows.”

“Microsoft was the first major enterprise user of the Embodied Carbon in Construction Calculator and is testing the tool (hosted in Microsoft Azure) on its 17-building remodeling project at its headquarters in Redmond, Washington, with the goal of a 30% embedded carbon reduction. proud to be a of the early adopters of EC3 while being strategic partners for Bentley Systems,” said Katie Ross, Global Sustainability Lead, Real Estate and Facilities at Microsoft. “The convergence of the EC3 tool and the Bentley iTwin platform is a great example of how we want to accelerate sustainability through collaboration and demonstrates the power of data democratization.”

Designers and sustainability engineers in the architecture, engineering and construction (AEC) industry spend a significant amount of time assessing or reporting on the environmental footprint of infrastructure projects, primarily when manually exporting and collating data from counts and BOMs. It may also be prone to error and requires further verification of successful incorporation with carbon tools. In addition, AEC professionals do not want to be stuck with a single carbon calculator, as different calculators can produce different results (e.g. due to uncertainties in environmental product declarations (EPDs)) and CO2 reporting and certification requirements vary by of project, country or owner of the infrastructure.

The added integration with EC3 not only saves time with greater accuracy, but also provides uncertainty estimates of the EPD data and increases CO2 transparency thanks to Building Transparency’s open-source/open-access strategy. Users can integrate technical data created by different design tools in a single view using the Bentley iTwin platform, generate a unified report of materials and quantities and share it with different carbon analysis tools, now also with EC3, via cloud synchronization.

One of the joint users interested in this new integration is WSP, which uses both the EC3 database and the Bentley iTwin platform for infrastructure projects such as the Interstate Bridge Replacement program. “For WSP, the analysis and reduction of the carbon footprint is critical when planning, designing, building and operating an infrastructure project from start to finish,” said Thomas Coleman, vice president of WSP USA. Enabling better iTwin integration with EC3 is of great importance to us across multiple infrastructure projects. Implementing this link will reduce the time and cost of generating EC3-based detailed analyzes and reports on the carbon embedded in the design. Ultimately, we see this long-term collaboration as another step towards open, always relevant and up-to-date digital twins for infrastructure, where carbon calculation and optimization is inherent and transparent at all stages of the infrastructure life cycle throughout the value chain.”
