设计概要

在布罗德盖特5号大楼落成之前，伦敦瑞士联合银行

的员工分散在几处不同的办公点，其中一处是位于布

罗德盖特地产核心区东隅的一座大厦。业主最主要的

需求是建成一座可容纳包括交易、管理和后勤人员在

内的6 000名伦敦瑞士联合银行员工的新办公楼。此

外业主还提出了一些具体要求，例如接待区、用餐会

议设施及办公室须尽可能宽敞，同时要有一个高水准

的开放庭院等。设计的每一个环节都必须将能源消耗

和维护成本降至最低，这些是设计的关键。

recycled materials

Make conducted extensive research into the

recycled content of materials. Starting with a goal

of 20 percent recycled content by material value,

agreed between UBS and British Land, by RIBA

Stage D we were forecasting a value of 33.8 percent.

During procurement we were able to make further

improvements, resulting in a final figure of 38.6

percent recycled content by material value for the

completed building.

embodied carbon tracking

During design stage, we tracked the embodied

carbon of the materials through detailed modelling.

This informed the decision-making process and

mitigation measures decided by the design team,

which ultimately helped us to reduce carbon by 3

300 tonnes, or 8 percent.

100 percent sustainable timber

All timber and timber-based products used in the

construction of the shell, core element and first

phase of the landlord fit-out are guaranteed to come

from well-managed forests. As a result, 5 Broadgate

is one of only 80 buildings worldwide to gain

certification.

natural lighting and ventilation

1.5m-diameter light pipes and curved stainless

steel louvres provide natural lighting and ventilation

in atria spaces. The light pipes have the largest

possible diameter we were able to fabricate. They

vastly reduce artificial lighting and provide diffused

light without the unwanted and reduce heat gains.

waste diversion

Virtually 100 percent (99.6) of waste was diverted

from landfill.

an offiCe for the future

These exceptional outcomes are the result of our

unwavering focus on exceeding sustainability targets,

and our consequently unconventional approach to

sourcing. Engaging with the supply chain allowed

us to optimise materials in a way that the design

stage alone cannot do, ensuring the highest levels of

recycled material and keeping embodied carbon at

a minimum. It is our hope that, along with its unique

and impressive appearance, 5 Broadgate will also

be recognised for its contribution to the future of

sustainable design.
