Insight; Considering the Structure
In our latest collaboration we spoke with Liam Bryant from Webb Yates on the early role of structural engineering in developing energy efficient and low carbon buildings with sustainable structures. Considering carbon in early on in a project is key as 80% of carbon is determined by the time a building is operational.
The compelling session on sustainable engineering spotlighted the need to rethink how structures play a part in how we build sustainably. With buildings and construction responsible for 40% of the UK’s carbon emissions, the discussion emphasized that the path to net zero starts with smarter design.
Championing early engineer involvement and efficient structural forms, He advocates that ‘We need to be paying labour not materials’. He sees that we are currently facing the challenge of cheap materials.
From vaulted concrete roofs to fire-tested timber frames and load-bearing stone facades, the presentation showcased real-world examples of innovation in action using low-carbon materials like timber and stone.
Comparative analysis of structural materials revealed stark contrasts—timber offers low embodied carbon and sequesters CO₂, while steel and concrete remain carbon-intensive despite structural efficiency. Hybrid systems combining timber, stone, and minimal concrete emerged as a viable path forward.
Despite market claims, no truly “green” concrete exists. Supplementary cementitious materials like GGBS and PFA are limited in supply and may introduce environmental trade-offs. Liam urged caution against superficial sustainability claims. Debunking the myth of “green concrete,”.
Caution was urged around greenwashing with the takeaway being that sustainable design isn’t just possible—it’s essential with sustainable structures and engineer collaboration.
We consciously explore materials we use in every project. What is there impact on the environment, both locally in the structure they are used and in their wider context. Following on from our recent project we are looking at lower-carbon alternatives alongside stone for low rise buildings such as a no bake brick and straw bricks.
