Site 

4. The 539 pile foundations - each at an
average depth of 18 metres
3,300 tonnes of steel and
1,948 coffered concrete floor slabs
which make up the structure of the
building.
The building includes 329,218ft² of
office space spread over the basement,
lower ground, ground and 14 upper
floors.
The column-free structure of the
building enables an extensive range of
subdivisions to be made from a full
floorplate down to suites of 3,000ft².
Each floor can be subdivided into six
zones, providing maximum
occupational efficiency and flexibility.
Construction work began in July 2010

STRUCTURAL SYSTEM
Three concrete cores, Steel / Glass frame.

The building's distinctive form was
conceived in a notebook sketch by the lead
architect for the building, Mike
Hitchmough.
TThe building has been nicknamed the 'sliced egg'
because of its distinctive shape
The facade was originally to be powder-coated but
the client decided to spend an additional £120,000
on a bronze anodised finish.

system.

Design
One Angel Square is a three-sided building with
gently curving walls.
The walls are severed from the tenth floor by a
series of stepped terraces, which also function
as the roof of the building.
The main feature of the building is the full-height
atrium, which floods the interiors with natural
light.
Facade
The building features a double skin façade.
Louvres located at the top of the facade help in
minimising heat gain.The louvres can be opened
to allow hot air to enter the building and be
ejected through the top.
The louvres are closed in winter transforming
the facade into an insulated blanket around the
building.

9. The double skin facade and open atrium are the key to
creating natural heating, cooling and lighting.
ONE ANGEL SQUARE
The atrium, floods the interior of the building with light that reflects off
the white painted concrete coffered floors, reducing the amount of
artificial lighting required to illuminate the building from 550 to 300 lux.
Air is cooled or heated in the basement before being delivered to the
atrium through a displacement system. The air moves through various
floors through the atrium and ascends to roof level before being ejected.
Waste air is finally extracted over the
balcony edge using the natural stack
effect of the atrium thus negating the
need for large space-hungry extract
risers within the cores.

11. The Combined Heat and Power Plant
(CHP), powered by pure vegetable oil
produced by the cooperative farms,
provides most of the electrical and
heating requirements for the new
building with surplus energy that is fed
back at the national level. Grid.
Other energy efficiency features
include:
Heat recovery from computer systems
that will also help heat the building.
Low energy LED lighting and computer
equipment and systems.
High efficiency elevators for passengers
and services.
Underground ducts to bring fresh air
through a heat exchanger.
The project used a number of
initiatives to minimize fuel and energy
use during construction. The on-site
cabins were heated from a dedicated
gas supply rather than inefficient
electric heaters. In addition, a rental
store was established on site that
provided materials and tools, saving
time and costs, as well as reducing
fuel and CO2 emissions.

Resource efficiency
.
The trash pallets were recycled to create unique
and stylish furniture for use in the building once
they were vacated. Most of the remaining waste
was recycled through waste separation,
including a can collector and cardboard
compactor on site. Cardboard collected at the
site was recycled at the customer's recycling
facilities that were located adjacent to the site,
helping to further reduce carbon emissions and
transportation costs
.
Precast elements are used, such as cold-formed
beams and bathroom modules, which decreased
the number of material deliveries and reduced
the waste associated with on-site assembly.

The Biodiversity
The site was contaminated with Japanese Fallopia,
a highly invasive species. Working with a
specialized subcontractor, we ensured that the
building's footprint was completely rhizome-free,
ensuring that the spread of Japanese knuckles was
minimized.
Roofing plants and planting in the public realm have
been used to help enhance local biodiversity.
