TOWARDS DIGITAL SHARING OF VERIFIED GLOBAL WARMING POTENTIAL DATA IN CONCRETE REINFORCING BAR
Construction industry professionals’ expectations of the quality and accessibility of Carbon Dioxide equivalent (CO2e) emissions data with concrete structures have increased considerably because of Net-Zero declarations, the widespread adoption of reduction targets and transition pathways towards these goals.
We have outlined how Life-Cycle emissions data is accurately calculated for specific steel producers, reinforcing products and fabrication, how 3rd party verification provides confidence in it and how an innovative collaboration is developing a solution that aims to digitise the steel reinforcing steel supply chain so this information can be used by design engineers and other construction stakeholders to help drive down emissions.
This is laying the foundation to create a digital twin of the built assets with accurate reinforcing steel information being traced from as-designed 3D Building Information Management models (BIM) through manufacturing, robotic-driven fabrication and installation, to as-built BIM models for handover.
Upfront ‘embodied’ carbon emissions – measured as its Global Warming Potential (in CO2e per tonne of reinforcing product) - and other environmental data, held within a fully verified Environmental Product Declaration (EPD) will flow through this system enabling the easier identification and selection of lower emission concrete reinforcement and the accurate calculation of asset level embodied emissions. This in turn can increase the credits achievable within ‘Green’ building and infrastructure rating systems and can support sound decision making in the race to Net-Zero.
