the most sustainable office building in the world. one of the most high-tech architectures around the world

1. The Most
Sustainable Office
Building in the
World
The Bloomberg's
European HQ

2. • an office building in London
opened in 2017
• owned by Bloomberg L.P. and
functions as their European
headquarters.
• It is at 3 Queen Victoria Street, to
the west of Walbrook, on the site
previously occupied by
Bucklersbury House.
• according to the BREEAM rating
system It has an outstanding
score of 98.5%, surpassing any
other large-scale office
development.

3. • The building incorporates innovative
features that reduce its environmental
impact, such as
• natural ventilation
• integrated ceiling panels,
• water conservation systems
• smart lighting
• a bronze facade that reduces solar gain.
• it is respectful of its historical and cultural
context, incorporating the remains of an
ancient Roman temple and a public arcade
that reconnects two historic streets.

4. • The building was conceived together
by Mike Bloomberg and Lord Norman
Foster of Foster + Partners and
delivered by Sir Robert McAlpine and
Stanhope plc.
• at 3.2-acre(102190 m²) it occupies a
full city block
• The façade is defined by 9,600
Tonnes of Derbyshire sandstone
structural frame, with a series of
large-scale bronze fins that shade the
floor-to-ceiling glazing.
• The fins give the building a visual
hierarchy and rhythm as they vary in
scale,

5. • Inside, the floors are linked by custom glass lifts
and a 210m helical bronze "ramp", which
dominates the interior of the building.
• Express lifts take visitors from the lobby, a self-
supporting "vortex" of three curved timber
shells, to the double-height pantry on the sixth
floor, with view of St Paul's Cathedral.

6. Sustainable
design features
• Integrated Petal-design Ceiling
• Natural Ventilation
• Smart Airflow
• Water Conservation
• Green ‘Living Wall’
• Connected Building
• Money Saving

7. Integrated Petal-
design Ceiling
• featuring 2.5 million individual aluminum “petals”, inspired
by the pressed metal ceilings of New York.
• The ceiling petals provide a range of services – lighting,
cooling, acoustic
• “combining various elements of a typical office ceiling into an
energy-saving integrated system”
• 500,000 LED lights, which cut energy use by 40 percent
compared with a standard system.
• Its unique petal design also helps with the aesthetic
appearance

8. Natural Ventilation
• larger, northern building’s expansive, deep-plan floor
plates can be ventilated and cooled using natural
ventilation.
• Outside air will enter the floor plates through the
purpose-designed, vertical bronze fins that line the
building’s façade and frame the glazing.
• The fins incorporate acoustically treated vents that
open and close to control airflow.
• From the floor plates, the air will rise up and out of
the central atrium. It is only the northern building
that incorporates natural ventilation;
• the smaller, southern building does not have an
atrium and, as a consequence, is mechanically
ventilated.

9. Smart Airflow
• The integrated ceiling panel consists of cooling pipes in a helix shape
used to cool the space.
• The 50% ratio between solid and void, combined with the helical
shape, enhances air flow around it, allowing fresh air to be supplied
via diffusers from above.
• The flexibility offered by elevated chilled water temperatures
provides future proofing against expected climatic temperature rises
and future tenant requirements

10. Water Conservation
• The building is 70% more water-efficient than a typical office building.
• An on-site water treatment plant allows to collect and reuse
rainwater from the roof, as well as “grey water” from sinks, saving 25
million liters of water a year.
• Recycled water feeds airline-style vacuum-flush toilets, which use net
zero mains water.
• vacuum drainage, a technology usually associated with boats and/or
trains, which had the potential to significantly reduce the water
demand of the building.

11. Green ‘Living Wall’
• The high-ceiling pantry is a great space
for meetings with colleagues and clients.
It overlooks St. Paul’s Cathedral and is
flooded with natural light from the
atrium above — making it a perfect
space for a “living wall.”

12. Connected Building
• ‘Connected Building’ system which
integrated and connected disparate systems
(including BMS/HVAC, Access Control, CCTV,
Lighting, power management, EMS, Fire
Alarm, AV/Room Booking, Lifts, Natural
Ventilation, Air Quality, Water Dispensing) to
a Tridium based ‘Middleware’ platform.
• The system provided Bloomberg with a
single connected environment, managed
from a ‘single pane of glass’ (SPOG).
• Systems were integrated utilising open
standard protocols where available and APIs
(application programming interface) to
integrate proprietary/closed systems.

13. Money Saving
• Bloomberg says its sustainability commitments have helped the
company save $95 million in operating costs since 2008.
• The company has eliminated nearly 700,000 metric tons of CO2 and,
with the addition of the new London building, now has 34 LEED or
BREEAM-certified projects globally.
• By the end of 2017, nearly 70% of the company’s 19,000
employees occupy a sustainable office building.
• Bloomberg has been a zero-landfill operation in London since 2010;
waste is recycled, composted or converted to energy.

15. Conclusion
• The Bloomberg Office building in London is a
remarkable example of sustainable and high-tech
architecture that has set a new standard for modern
office buildings.
• The building's innovative design, energy-efficient
features, and state-of-the-art technology have made it a
model for sustainability and environmental
responsibility.
• The building's focus on sustainability is evident in its use
of renewable energy sources such as solar panels and
ground source heat pumps.
• These features not only reduce the building's carbon
footprint but also enhance the well-being and
productivity of its occupants.
• The building's unique design also contributes to its
sustainability by maximizing natural light and ventilation
while minimizing energy consumption.
