Applying Carbon Values to BIM Objects

ON DEMAND

Join NBS and Circular Ecology for an essential webinar designed for built environment professionals looking to enhance the accuracy and transparency of embodied carbon modelling within BIM workflows.

This session introduces practical methodology for applying A1–A3 cradle to gate carbon values to BIM objects of all types - including simple materials, layered assemblies, manufactured components, and complex composite systems.

Attendees will discover how to source and apply emissions factors, material densities, and integrate data from trusted datasets such as the ICE Database, EPDs, and more. The webinar also walks through example calculations for A4 transport and A5 installation impacts, demonstrating how to model these stages with clarity and consistency.

What you’ll learn

• How to apply A1–A3 embodied carbon factors accurately across different BIM object types.
• How density, declared units, and geometry influence carbon values and why they matter.
• Where to find reliable emissions factors and how to use them.
• How to calculate A4 transport and A5 installation emissions using industry aligned methods.
• How to structure BIM object properties for consistent and auditable carbon reporting.

Who should watch?

Architects, engineers, specifiers, sustainability leads, product manufacturers, BIM authors, and anyone responsible for whole life or early stage carbon assessments.
