Redevelopment of an office and mixed site just off Oxford Circus in the very heart of London’s West End, and directly over the new Crossrail Bond Street station.
This is a substantial mixed use proposal incorporating new build, and facade retention schemes. It stretches from the north side of Hanover Square to Bond Street.
Sturgis Carbon Profiling was appointed by Great Portland Estates to carry out Whole Life Carbon assessment for the scheme and suggest embodied carbon mitigation strategies. The 4 blocks of the Hanover Square development have been analysed individually to provide a clear carbon picture for each one, including options for emissions reduction. The results for each building have also been combined to a total for the scheme depicting the total site wide carbon impact.
A comprehensive Stage 2 carbon baseline has been developed which together with relevant potential carbon reduction options have an overall potential savings of some 5,500 TCO2e. If implemented the recommended options will reduce the embodied carbon footprint of the scheme by 23%.
The high importance of internal finishes in this particular project has been highlighted via the carbon baseline analysis.
The carbon reduction options explored include not only material and product alternatives but also more overarching design decisions like the selection of structural frame systems.
The carbon footprint of this Scheme compares well against similar buildings on a per m2 basis due to its relatively low carbon features e.g. steel frame.
