UNIVERSITY OF QUEENSLAND GLOBAL CHANGE INSTITUTE
Brisbane, Australia
INTRODUCTION
• The Global Change Institute is designed by HASSELL which
meets the world’s most advanced levels of sustainability. The
building demonstrates sustainable technological research
and pilots innovative sustainable building solutions.

•It also act as a live research site, with the building systems
and occupants used to assess optimal comfort conditions in
low-energy buildings for the sub-tropics.

• Built in 2013

• Architect - Hassell Group

• Area - 3865sqm.

• Location - Brisbane, Australia

• The building has been designed to work with the natural

environment and operates as a zero energy and carbon
neutral workplace.
SOME KEY FEATURES

• External perforated operable screens sit beyond the

operable glazing line to control both solar load and glare
internally. Direct sun and the impacts of wind and rain can
be controlled.

• The air supply system utilizes the thermal mass of the

basement to temper the outside air prior to being
dehumidified and delivered to the upper level
displacement system.

• The Green Wall in the atrium performs a role in the bio-

filtration and re-oxygenation of return air, supplementing
fresh air supply from the basement.

• The building engages the thermal mass of its construction

to moderate internal temperatures. Each floor is
constructed of precast Geopolymer floor beams. These are
exposed at their under surface and temperature controlled
by the use of hydronic coils to keep temperature at a low
range.
DAY LIGHTING

ATRIUM ROOF
Allows natural light into the
interior while insulating from
the sun’s heat

Internal atrium is roofed by

a triple skin operable ETFE
roof.

Pneumatically inflated
pillows reduce solar loads
into the atrium space
during peak solar load
periods.

Light weight material

reduces the Co2 footprint
useful for the building’s
thermal design.
FAÇADE DESIGN

MOTORISED SUNSHADES
The building features an operable sun
shading system that tracks the sun and
protects the glass louvers which encourage
natural ventilation. The air flows across
occupied spaces to the central atrium which
acts as the building’s lungs, discharging
warm air through its thermal chimney.

PERFORATED ALUMINIUM SCREENS

It is environmentally sustainable and recycled
materials along with the ability are to be
recycled after use.

LOUVERS
Louvers operate automatically in response to
humidity and temperature levels inside and
outside the office. Automated louvers system
moves around as the day progresses,
thereby providing maximum sun shading.
NORTH FAÇADE Solar panels arranged in a
group to capture maximum
amount of sun light to
convert it into usable
electricity.

NATURAL VENTILATION
THERMAL CHIMNEY
Draws warm air up and out of the
building and draws cooler air in from
the basement and outside. Way of
improving the natural ventilation.

FAÇADE
Perforated screen and louvers allow
the air to flow into the building and
cool down the spaces.

GREEN WALL
Draws air up to a green wall, filter
and cools down the air. It performs a
role of bio-filtration and re-
oxygenation.

OPEN AND BIG VOLUME SPACES

Openness of the spaces and the
circulation spaces allows air to flow
through the building and natural
ventilation to occur.

- Minimize energy consumption with user-friendly systems.

GREY WATER TREATMENT PLANT

It cleans rainwater for use in showers
and taps. Water is recycled for
comfort cooling and recycled again
for irrigation.

ENERGY SYSTEMS
Solar photovoltaic panels generate
energy in the overall building.
There are 6 Battery towers that get
charged by solar PV panels on the
rooftop which drive the cooling
system.

National Library, Singapore. Daylight Factor: Skylight and light shelves design

The light shelves are paired with external shading device that is placed at the same level of
the internal shelves. The external shading reduces glares from the windows.

The skylight is built in small

proportion to building surface area
due to consideration of solar heat
gain.

The giant blades block direct sunlight while reflecting them deep into interior spaces.

These 20 foot wide super fins protect curtain wall

from glare, yet maximise the daylight in the
building.
Penetration of sunlight into the
building into the atrium, resulting in Laneway sunshades protect the north-western and
the diffusing of light through spaces, south-eastern facades from solar penetration.
reducing the need for artificial
lightings.
National Library, Singapore. Daylight Factor: Skylight and light shelves design

Overhangs are designed to cut sun on altitude angle of 30

deg. Or above.
National Library, Singapore. Daylight Factor: Sky Court

A garden is located at level 10 (A), is opened up untill level 15.

The plethora amounts of sky court shown in (B)(C)(D) able to

lower down ambient temperature to bring energy efficiency to
the interior.

The 2 main gardens, each measuring 40m high, situated at 5th

and 10th floor, contain 12 m high trees that helps the micro
climate and improves productivity of the people working there
by taking care of their psychological health.

Stack effect helps in keeping the building at better

temperature.
National Library, Singapore. Facade design: Light Shelves and Curtain Wall

White polypropylene are used as light shelves to reflect and

redirect sunlight.

These 20 foot wide super fins protect curtain wall from glare, yet
maximise the daylight in the building.

The facade of this building is the most interesting

part of it. It is 80% made of glass and finished with
modular sunshades fabricated and coordinated
with curtain wall system as well as internal
partitions. Double glazing glass prevents energy
transfer from solar radiation and ambient
temperature and reduces air conditioning needs.
Facade treatment is customised for all different directions. Sunrays The U value for the glass is 1.62 W/sqm K. On top

there are still significant temperature differences on the inner and

National Library, Singapore. Facade design: Low-E Double glazed glass and Canopy

Double glazed with high quality low emissivity glass was used
on the building facaed to control the percentatge of
natural light to enter the interior spaces. The hard layer in
double glazed glass can be intermediately efficient and
generally more efficient compared to normal glass.

The glass enclosure and extensively louvered facade

gains warm lighting eperience to provide pleasant reading
environment.

Improved sound insulation by creating a barrier between

the inside and environment outside.

Air tight construction of double glazed windows create

thermal insulation.

Less energy is used to heat up or cool down the space.

Resulting in lower energy bills.
