FAÇADE MATERIALS
BARK FAÇADE
The eastern core and façade used the analogy of bark. It was conceived as a
protective layer that filtered light and air into the naturally ventilated wet
area spaces behind. The final solution consists of two overlapping layers
of perforated metal with polycarbonate walling and fixed metal louvres.

A louvers system covering the western façade with timbre
louvers able to move and photovoltaic cell to ‘track’ the sun

An integral part of the larger one-north master plan that is developed by
JTC. Together with the adjacent Biopolis and Mediapolis land parcels,
the three entities within one-north aim to become incubators for biomedical
research, new media production and high-tech software engineering
development in Singapore and in South East Asia.

WIND ANALYSIS
44. Extensive sun-shading louvers
• Limate-responsive façade design responds directly
to local sun-path.
• Singapore is at the equator and the sun-path is
almost exactly east-west.
• Facade studies analyzing the solar-path determined
the shape and depth of the sunshade louvers, which
also double as light-shelves.
• This solar shading strategy further reduces heat
transfer across the building’s low-e double-glazed
perimeter facade, contributing to an extremely low
external thermal transfer value (ettv) of 39 w/m2.
• Assist in establishing comfortable micro-climates in
habitable spaces along the building’s exterior

STRATEGY
LOUVERS
45. Atrium Skylight
• The skylight louvers system at the top of the atrium
for stack effect.
• It is a fail-safe system – upon the detection of fire
within or near its proximity (via the building’s
intelligent management system), the skylight
louvers will automatically open up to disperse potential
smoke or heat build-up due to the fire.
• Still will function even without the building’s main
power supply, in case the latter is damaged by fire.
This strategy eliminates the requirement of costly and
power hungry engineering smoke control
systems, which is commonly used in conventional
atrium design.
• Designed to close during adverse weather to shield the
occupants from rain via an array of rain detection
sensors.

STRATEGY
SKYLIGHT
46. Eco-cell
• Located at the building’s north-east corner where
the spiral ramp meets the ground
• To allows vegetation, daylight and natural
ventilation to extend into the car-park levels
below.
• Lowest level of the eco-cell contains the storage
tank and pump room of the rainwater recycling
system
3
STRATEGY
ECO-CELLS
47. Solar Shaft
• To allows daylight to penetrate deep into the
building’s interior.
• Internal lighting operates on a system of sensors
which reduces energy use by automatically
turning off lights when adequate day lighting is
available.
• Landscaped terraces within the solar shaft bring
added quality to adjacent spaces and enhance
views up into the building from the street below.
• Creation of refreshingly new high-rise office
interiors enhanced by ambient mood lighting
that constantly changes with the play of sunlight
and shadow.
3
STRATEGY
SKYLIGHT
49. Planter box design
• To keep the building facade elegant, the planter
boxes on the spiral ramp are designed to be as
shallow as possible, to reduce the “bulkiness”
they would otherwise create when viewed from
the exterior.
• The lack of deep soil means that the plant
species had to be carefully selected to ensure
that their roots are able to spread horizontally,
instead of digging deep downwards for stability.
Roof top Garden + Sky Terraces
• Acts as a thermal buffer and creates areas for
event spaces, relaxation and spontaneous
social activities.
• These extensive gardens allow for interaction
between the building’s occupants and nature,
offering opportunities to experience the external
environment and enjoy views of the treetops of
adjacent one-north Park.

PLANT SELECTION
Plant Selection
•It allows for fluid movements of
organisms and plant species between
all vegetated areas within the
building
•To enhance biodiversity and
contributing to the overall health of
these ecosystem
•To mimic natural tropical landscape
environment
•Lighting condition on each
building’s façade was consideration
factor, ensuring the chosen species
could strive in specific location

Materials were chosen to reduce the environmental impact of the building both during construction and use; because it combines exceptional transparency and an ultra-neutral aesthetic
Black = ideal glass
Visible light transmittance (VLT) = 71% ; Argon = extremely low thermal conductivity, high density (38% denser than air at 1.784g/l at STP) source: http://www.windowworldrockford.com/
