Westminster City Council’s bold “retrofit-first” policy, part of its updated City Plan, marks a significant step towards making London a more sustainable city. Aiming for net-zero emissions by 2040, this policy prioritises upgrading and reusing existing buildings rather than demolition and new construction. The shift is designed to reduce the city’s carbon footprint, with structural engineers playing a pivotal role in bringing these projects to life. Here’s how structural engineering is essential to the success of this new approach.
The Benefits of Retrofit
Retrofit focuses on preserving at least 50% of a building's original structure, including key elements like the foundations and floors, while upgrading its energy performance and structural resilience. This not only reduces the embodied carbon emissions associated with new construction but also extends the life of older buildings, making them more sustainable in the long term.
Experienced London Structural Engineers, like JMS Engineers, ensure that retrofitting is done safely and efficiently. Our team can assess existing buildings, determine which elements can be retained, and design upgrades that improve energy efficiency, all while ensuring the structure meets modern standards.
Whole-Lifetime Carbon and Embodied Carbon Targets
One of the most important elements of the retrofit-first policy is the focus on whole-lifetime carbon assessments. These assessments measure the carbon emissions over a building's entire life, from construction through operation and eventual demolition. By working with structural engineers, developers can identify ways to extend the life of buildings and reduce their overall carbon impact.
Westminster’s plan also introduces strict embodied carbon targets, aiming to save 480,000 tonnes of carbon by 2040. Structural engineers are key to meeting these targets. At JMS Engineers, we design projects that minimise the carbon footprint of materials and optimise structural designs for energy efficiency.
Supporting Affordable Housing and Sustainable Development
The updated City Plan also places emphasis on affordable housing, even for small-scale residential developments. This presents a challenge, as developers need to balance cost-effective solutions with sustainability goals. Structural engineers provide innovative designs that are both economical and environmentally responsible, helping developers meet affordability targets without compromising on sustainability.
