30 The Bond is an A Grade office
building located in Millers Point,
Sydney and is currently the
headquarters for Lend Lease. The
building is part of a complex on
Hickson Road which also includes
heritage buildings, a residential
building and a public plaza. “The
Bond” committed to a 5 star energy
rating (AGBR
), resulting in 30% lower
greenhouse emissions than a typical
office building.

KEY AREAS OF ACHIEVEMENT
• The building features a 5 star ABGR
energy rating, the first office building
in Australia to sign a commitment
agreement.
• Features the first use of chilled
beams.
• Plants used as a natural air filtration
system.
• High amount of recycled timber
used in the fitout.
PROJECT BACKGROUND
The site of the building is within the
former Australian Gas Light (AGL)
gasworks plant established in 1871
to provide lighting to the surrounding
area. A four storey sandstone wall,
originally hewn by convicts, remains
as a main feature of the atrium.
Lend Lease staff gave a large amount
of input into the design and fitout of
the building. Staff identified three key
issues to address in the design of the
building: greenhouse gas emissions,
indoor environment quality and social
aspects.
ESD CONSIDERATIONS
MANAGEMENT
The management have taken
thorough steps to ensure the ESD
initiatives incorporated into the design
have been maintained during the
crucial stage of the building’s life
cycle: operation.
Before moving into the premises,
the staff were given presentations
about the sustainability initiatives
incorporated in the building, how the
building works and ways to maintain
the sustainability of the building.
They have also conducted half-yearly
presentations to staff regarding
the results of their pre and postoccupancy
evaluations of the building.
An internal website is updated
each month with waste, water and
energy results so staff can track their
progress. Another website available
is an A-Z users’ guide, so staff have
detailed information on a variety of
topics from the chilled beams to
wintergardens, at their fingertips.
ENERGY
A chilled beam air conditioning
system is the major contributor to the
reduction in energy consumption.
Chilled beams operate by pumping
chilled water through cooling elements
in the ceiling. Hot air created by
occupants and equipment (such as
computers and lights) is cooled by
the chilled beams and falls, creating a
natural convection process of hot air
rising and cold air falling. Additional
radiant cooling from the chilled beams
supports the convection process.
In addition to the chilled beams,
fresh air is continually provided to the
workplace and exhausted out of the
building without being recirculated.
This significantly increases the air
quality within the office space and
considerably reduces the risk of sick
building syndrome.
