Greenwich Council has approved residential tower scheme by Jo Cowen Architects next to O2 arena on Greenwich Peninsula.
JCA was appointed by Knight Dragon Developments Ltd to design 266 apartments (20-storey block) of a mixed-use residential scheme with amenities and dedicated Cycle Hub (multi-story hub) at the heart of Peninsula Quays.
Separately, JCA was appointed to develop Plot 1.03 to RIBA Work Stage 3, previously developed to RIBA Stage 2 by Pilbrow and Partners, with 600 apartments (35-storey East Tower, 29-storey West Tower) including swimming pool, gym, retail and associated green amenities to meet the new Building Safety Act 2022 and the Building Safety Regulator’s (BSR’s) Gateway 2 requirements for Higher-Risk Buildings.
As both Plots (1.02 and 1.03) had a common link element the design process required unified approach to fire safety with careful consideration of fire compliance against BS 9991 and 9999.
At the same time the mixed-use nature of the entire development combined with two completely different façade systems required separate energy strategies. The Plot 1.02 was designed to use precast concrete panels with brick finish and the Plot 1.03 adopted unitised façade system.
Both systems present different challenges to achieve the same compliance requirements especially in relation to AD Part E (noise), AD Part F (ventilation and heat recovery), AD Part L (carbon emission) and AD Part O (cooling and overheating).
The unitised façade system required frequent assessment of ‘solid to glazed elements ratio’ to mitigate overheating and achieve the high level of façade performance required. As the number of elements to be monitored was large, the only way to achieve the desired outcome was to come with a simple but innovative solution.
JCA’s BIM team developed specific Revit Script and Revit Families which allowed for the unitised elevations to be parametrically adjusted and provide instant and accurate reporting on ‘solid to glazed’ ratio.
We have to mention, that the project utilised Revit as the main modelling software and was used by each discipline. Additional clash detection and tracking via Navisworks and BIMcollab was deployed to provide fully coordinated design.
