Case study of Energizing Kowloon
East Office:
Use of Second-hand Freight Container
Low embodied energy and sustainable materials were adopted
in the construction. The use of second-hand freight containers as
the main building structure minimised the energy consumed and
environmental impacts during the extraction of virgin materials and
the manufacturing process. Similarly, the embodied energy and
environmental impact caused by transportation of construction
materials were reduced by choosing manufacturers in the region
within 800 km of the site.
Recycled Paving Blocks
In addition, the paving blocks for the site were manufactured from
recycled aggregates, recycled glass, fly ash, coated with titanium
dioxide (TiO
2
), which help abate nitrogen oxide (NOx) from road
vehicles. This purifies the ambient air and benefits the health of the
building users and pedestrians.

Reused Glass Wall
Two tempered glass panes originally
installed at the entrance of the
atrium staircase were reutilised to
build a conference room, serving
as a good example of reducing
construction waste. It also reduced
material costs in the fitting-out
works.

Hong Kong – Green Sky:
Planning Ahead
87% of Green Sky can be easily relocated to a
future office space. The Genius Wall, an eco-
friendly moveable glass wall partitioning system
takes just a few days to install or disassemble. As
smaller tenants in Hong Kong are often restricted
to only two or three years leases, planning ahead
to reuse building materials saves money and
reduces construction waste.
Second Hand Furniture
Reuse and Save: 100% of the loose office furniture
is second-hand, purchased at only 60% of the
cost of new furniture. This freed up funds to
invest in other green features such as a real-time
energy monitoring display and carbon offsets from
Conservation International’s Carbon Fund, which
offsets Green Sky’s carbon emissions by protecting
Amazon forests in Peru.
