New build vs. refurbishment: The role of carbon assessments in data-driven decision making

About this webinar:

What if building green didn’t just save the planet—but made you money?

As the construction industry accelerates toward net-zero targets, understanding the carbon impact of design choices has never been more critical. Whether you're planning a new development or considering refurbishment, making the right decision starts with a robust carbon assessment.

In this expert-led session, Cudd Bentley Consulting joins forces with One Click LCA to explore how life-cycle carbon assessments (LCAs) can guide strategic decisions between new-build and refurbishment. Using real-world insights and practical examples, the session will unpack how carbon data can reveal the true environmental cost of each approach.

Whether you’re navigating a complex retrofit or debating demolition and rebuild, this session will help you understand how carbon modelling informs smarter, more sustainable choices.

What will you learn?

The role of carbon assessments in evaluating refurbishment vs new-build scenarios
How to use whole life-cycle carbon (WLC) assessments to support low-carbon decision-making
Real project examples where carbon assessments have changed the course of design
Why new build isn’t always the lower-carbon option — and why
How Cudd Bentley integrates carbon modelling into building services engineering
Tips for making carbon data meaningful to clients and design teams
