Public garden and urban greening Public garden terrace 55 Gracechurch Street
Accessed via two dedicated public lifts through a secure lobby at ground floor. Supported by CoL Police.
Lobby accessed from the public realm within the building and via St Benet’s Place.
The public garden terrace, walkway and ancillary space have a combined capacity of around 150 people.
Based on a dwell time of 20-30 minutes, an arrival and departure rate of between 450 and 300 people per hour has been assumed.
These rates would result in a maximum queue length of 12 people. The 30m² lobby provides twice the space required for a queue of this size.
Should a longer queue form this would be managed inside the building to ensure St Benet’s Place is kept clear and in a manner which prevents any public routes being blocked.
A system to manage access at full capacity will be developed prior to occupation utilising the latest technology.

Committing to a target BREEAM Score of 88.2%(Outstanding).
Using steel with a 40% recycled content and concrete with Granulated Blast-furnace Slag (GGBS) willsignificantly reduce the embodied carbon of the building.
Proposing the leasing of some M&E equipment for improved maintenance, repair and end of serviceable lifereuse & recycling.
Committing to a 98% waste diversion from landfill rate target duringconstruction.
Committing to a construction waste generation amount of 6.5 tonnes per 100m2 of gross internal area.
Creating flexible spaces for future adaptability to reduce future waste generation.
Recycling stonework from the original structure.
Encouraging future tenants to reuse parts of the speculative showfloor.
Circular economy & embodied carbon 55 Gracechurch Street
Life Cycle Assessment performed that included embodied and operational carbon emissions.
The graph compares the results with the carbon emissions of the existing building.
With the embodied carbon of the new development included, the breakeven point for carbon emissions is 2034.
Cradle to practical completion embodied carbon emissions are 891kg/CO2e/m² and meet the GLA’s benchmark target 1000kg/CO2e/m².
Life cycle (cradle to grave) carbon intensity is 1,241kg/CO2e/m² and sits within the GLA’s benchmark emissions target 1,500kg/CO2e/m².
Life Cycle Assessment 55 Gracechurch Street
All electric building.
Utilising 100% outside air through floor-by-floor air handling units to provide free cooling 92% of theyear. A high efficiency facade with dynamic automated blinds to limit solargains.
Rainwater harvesting for irrigation with attenuation to limit runoff rates easing pressure on local drainagesystems.
Greywater will be recovered and re-used.
Chilled water, heating and hot water from a sustainable source. Flow restricted taps for each hand basin with infraredcontrol.
A consolidated out-of-hours servicing strategy will reduce congestion, improve air quality and pedestrian andcyclist safety within the City. Cargo bikes will be used to make deliveriesduring the day.
The thermal mass of exposed concrete soffits reduce temperature fluctuations and reduce energyconsumption.
Further sustainability features 55 Gracechurch Street
Passive infra-red (PIR) lighting controls will reduce energy usage and light spill.
High quality low energy lighting and controls will be utilised throughout.
Garden lighting will be carefully designed to minimise light spill.
Lighting control systems will dynamicallyadjust lighting levels to minimise energy use.
The levels of illuminance for proposed routes and open spaces will enhance the pedestrian experience, creating a safe and welcoming public realm.
The final lighting strategy will be developed in line with the City of London’s External LightingStrategy.
Lighting strategy 55 Gracechurch Street
Moderate adverse (significant) daylight impact to 9B Eastcheap, recorded used as serviced apartments but with a consent that would allowresidential use. 23 windows serving 19 rooms are assessed. 19 of these windowswould experience a reduction beyond BRE Guidelines recommendations in daylight when recorded using VSC criteria (20%+). 11 of these windows servebedrooms (less important in BRE Guidance terms) and eight serve living room-diners, of which five already have very low light levels and therefore variance would be negligible and three would potentially have a noticeablealteration.
Minor adverse (not significant) daylight effects to The Ship Public House (residential element) and St Margaret Pattens Church. Negligible daylight effects to all other receptors.
Negligible sunlight effects to all receptors identified includingsensitive buildings and open spaces.
Negligible light pollution effects to all receptors.
No significant (negligible to minor adverse) solar glare effects to road viewpoints.
