Embodied carbon refers to the carbon emissions associated with the construction and materials used in buildings. As sustainability becomes a paramount concern, industry stakeholders are increasingly favouring the retention and refurbishment of existing stock over the demolition and redevelopment of structures. This article explores why this trend is gaining traction, the constraints involved, and the wide-ranging benefits of adopting a more sustainable approach.
The environmental imperative
The industrial and logistics sector has long been associated with a significant carbon footprint, and embodied carbon accounts for a substantial portion of this impact. Traditional practices of demolishing and redeveloping buildings contribute to the release of substantial carbon emissions through material disposal, energy-intensive construction processes, and transportation. Focusing on retaining and refurbishing existing stock provides an opportunity to reduce the sector's environmental impact, conserve resources, and promote a circular economy approach.
Constraints to overcome
While the trend toward retaining and refurbishing existing stock is gaining momentum, it is not without its challenges. One of the primary constraints is the need for innovative design and engineering solutions to adapt older structures to meet modern functional and operational requirements. Retrofitting buildings to align with current energy efficiency standards can also present difficulties due to existing building regulations. In some cases, the limited availability of suitable sites for new development, along with high costs associated with land acquisition, further incentivise the reuse of existing structures.
Benefits of retrofitting
Reduced embodied carbon: Refurbishing existing buildings significantly reduces embodied carbon emissions compared to constructing new ones. By reusing materials, retrofitting systems, and upgrading infrastructure, the sector can make substantial progress toward achieving carbon reduction targets and combatting climate change.
Preservation of resources: Retaining and refurbishing existing stock helps conserve valuable resources such as raw materials, water, and energy. It reduces the demand for new construction materials and minimises the environmental impact associated with their extraction, manufacturing, and transportation. By preserving resources, the sector can contribute to a more sustainable and resource-efficient economy.
Cost savings: Refurbishment projects often prove to be more cost-effective than demolishing and constructing from scratch. Retrofitting saves on demolition costs, land acquisition expenses, and infrastructure development. Furthermore, refurbishment initiatives can benefit from various financial incentives, such as tax breaks, grants, and financing options aimed at promoting sustainable development. The potential cost savings associated with refurbishment make it an attractive option for industry stakeholders.
Historic and cultural value: Many industrial and logistics buildings hold historical and cultural significance. Retaining and refurbishing these structures preserves their architectural heritage, contributes to local identity, and fosters a sense of community pride. By maintaining these buildings, the sector can strike a balance between sustainability and conservation.
Improved market competitiveness: Sustainable practices and environmentally responsible operations are becoming increasingly important to stakeholders, including tenants, investors, and customers. Retained and refurbished buildings showcase a commitment to sustainability, attracting eco-conscious tenants and enhancing market competitiveness. By embracing refurbishment, the sector can position itself as a leader in sustainability and meet the evolving demands of a more environmentally conscious market.
Case study - 160 Edinburgh Avenue, Slough Trading Estate
The award-winning project at SEGRO’s development, 160 Edinburgh Avenue, Slough Trading Estate, stands as a testament to prioritising embodied carbon reduction within industrial refurbishments. Following its completion, an embodied carbon report was commissioned, revealing a substantial decrease in total embodied carbon by 318 tonnes CO2e compared to industry benchmarks LETI 2030. This achievement was a direct result of SEGRO's explicit brief to refurbish their existing unit, showcasing a commitment to sustainability by reducing the project's carbon footprint. SEGRO has consistently aimed for innovation and sustainability, contributing to some of the UK's most environmentally friendly industrial structures.
Conclusion
The industrial and logistics sector recognises the imperative to address embodied carbon emissions and adopt sustainable practices. Retaining and refurbishing existing stock offers a practical solution that aligns with environmental goals while addressing resource constraints. Despite challenges related to design adaptations and regulatory compliance, the benefits, including reduced embodied carbon, resource preservation, cost savings, conservation, and improved market competitiveness, make this trend an imperative for the industry. By embracing refurbishment, the sector can reduce its environmental impact and lead the way towards a more sustainable future.
