81-103 King’s Road is a proposed 17,000m2 mixed-use development located in the Royal Borough of Kensington and Chelsea, London. KJ Tait Engineers calculated the Whole Life-Cycle Carbon (WLC) of the proposed building that conforms with the London Plan 2021 requirements for referable buildings.
In line with BS EN 15978, the following modules must be assessed:
Using OneClick LCA software, a baseline model was created from the RIBA Stage 2 Cost Plan and material benchmark data from RICS Whole Life Carbon Assessment for the Built Environment. Options to reduce the life-cycle carbon emissions were assessed with the Design Team and the associated carbon savings were calculated.
The following measures were agreed by the Design Team:
Together with the above measures, the upper floors will benefit from mixed-mode ventilation. This is expected to save 134kgCO2e/m2 in use, using today’s carbon factor.
The resultant scheme is one that betters the Greater London Authorities’ aspirational benchmark for offices for modules A, B and C.
|Aspirational Benchmark (kgCO2e/m2)
|Building Benchmark (kgCO2/m2)
|550 - 600
|B & C
|250 - 300
