Going the extra mile in learning how to produce sustainable buildings

Zenon Group (before Superstructures) is driving a proactive approach to reducing embodied carbon, placing sustainability at the heart of structural design.

The built environment is responsible for a significant proportion of carbon emissions and waste in the UK, making sustainability a critical priority for the construction industry. While much attention has traditionally been given to reducing operational carbon — such as energy used in heating and lighting, there is now growing emphasis on embodied carbon, which includes emissions generated through the manufacture, transport, construction, and eventual deconstruction of building materials.

Understanding embodied carbon allows engineers to assess and reduce environmental impact at the design stage, where the greatest influence can be achieved. Material selection plays a crucial role, as some materials such as concrete may have relatively low carbon intensity per unit but are used in such large volumes that their overall impact becomes significant.

Zenon Group (before Superstructures) is taking a forward-thinking approach by developing strategies to quantify and reduce embodied carbon across projects. This includes reviewing past designs, applying more sustainable alternatives, and measuring the impact of design changes. For example, a recent review of a small building project demonstrated how design adjustments could reduce embodied carbon by several tonnes highlighting the potential for even greater savings on larger developments.

Achieving these improvements requires early collaboration with clients and design teams. By engaging at the concept stage, structural engineers can influence key decisions around materials, structural systems, and construction methods, ensuring that sustainability is embedded from the outset.

However, barriers remain, including industry norms, limited demand, lack of established standards, and the perception of increased upfront costs. While sustainable design may require greater initial investment in consultancy and design time, it often leads to more efficient use of materials and long-term environmental and economic benefits.

Zenon Group (before Superstructures) is committed to overcoming these challenges by developing internal expertise, promoting collaboration, and continuously improving its processes. By adopting a data-driven approach and encouraging innovation, the company aims to support the transition towards net zero carbon construction.

Ultimately, sustainable design is not a one-time solution but an ongoing process of learning, adaptation, and collaboration. By integrating these principles into every project, Zenon Group (before Superstructures) is helping to shape a more sustainable future for the built environment.
