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.
