Zero Carbon London
→ Targeting BREEAM Excellent (Offices)
→ Urban Greening Factor 0.3 over 5.4 hectare site (masterplan)
→ At lest 55% reduction of operational energy against Part L
→ An embodied carbon aspiration of 300kg/CO2e/m2 is targeted for Building F
A central component in the Bermondsey Project masterplan, Building F is a former biscuit warehouse, constructed in the 1970s. This is being reimagined to create a mixed-use hub; adding 177 residential units above the existing roof line; creating retail and employment space on the lower floors; and extending the public realm.
The Biscuit Factory will be a hybrid building, combining reuse with new build. Grosvenor are exploring lower carbon alternatives to traditional concrete frames. While changes to regulations have made using CLT more challenging, Grosvenor and the design team are pioneering work with consultants and the wider industry to develop a solution compliant with the latest regulations.
As part of delivering Grosvenor’s Sustainability Development Framework the project team is being challenged to provide innovative design solutions to minimise embodied carbon through the building’s lifecycle. A cradle to practical completion target of 500kg/CO2e/m2 and 300kg/CO2e/m2 is targeted for non-domestic and residential elements respectively to deliver performance aligned with Grosvenor’s 2030 carbon objectives and long-term sustainability vision.
The masterplan is connected to a district heating scheme with local energy generation, from SELCHP, an advanced Energy Recovery Facility that uses non-recyclable waste to generate electricity, providing low-carbon energy and reducing the pressure on landfill sites.
Embodied carbon emissions are reduced by 16 per cent over the initial baseline model by retaining the existing warehouse. Other measures include the use of CLT hybrid solution for constructions of the upper floors, and the reuse of demolition material where possible, such as for landscaping components.
It is a zero private car scheme, and encourages sustainable travel. Green roofs contribute to SUDS and improve air quality and wellbeing. Passive ventilation, combined with MVHR, reduces energy use.
