One Island East is the latest development in TaiKoo Place, Hong Kong’s
largest, single-owned business district. This 70-storey, triple Grade-A
office building commands superlative views of the harbour and is within
the immediate proximity of both Taikoo and Quarry Bay MTR Stations.
The design and construction planning of One Island East is rooted in
concerns for the environment. Developed on a site of approximately
10,200 sq m, the building footprint only occupies less than 50% of the
site area, leaving ample ground floor space for landscaping for the
enjoyment of the tenants and the public. In the landscape garden, which
comprises about 75 % of the total development area, water features,
green parterre and canopy trees have been introduced to create a green
island for the neighbourhood. All the plants in the previous landscape
area have been retained for on and off site transplantation. About 10%
of the trees were either retained or transplanted on site. To echo this
green carpet, the main roof of One Island East is also designed as a roof
garden to provide an alternative amenity for the tenants. Moreover, all
the timber used in the project came from sustainable sources.
The envelope of the building is designed to allow maximum amount of
natural lighting while minimizing heat transmission so as to minimize
the use of mechanical ventilation. Like 83% of SPL developments,
One Island East has taken a further environmentally friendly solution
in mechanical ventilation by using central seawater cooling which is
more energy efficient than air cool systems and has no loss of seawater
by spray dispersion. The MVAC system is also equipped with energy
recovery from cool exhaust air by heat wheel to pre-treat incoming hot
fresh air, and energy-efficient chillers to minimize energy consumption.
Energy efficient LED light fittings are also substantially used for more
than 85% of decorative lightings.
Other than seawater cooling, One Island East is also provided with
rainwater recycling for flushing purpose and dual flush mechanism for
water closets to minimize foul water disposal. With the adoption of these
systems, we predicted a saving of a minimum 15% in use of fresh water.
Not only is the design heedful of the environment, the implementation
of the construction works has also been planned to reduce impact on
the environment. Innovative demolition method was employed to
