Hopewell Holdings Limited
Sustainability Report 2010/11
Enhancing Energy Efficiency in Buildings and
Reducing GHG Emissions
In 2010, we completed carbon audits for our major properties:
Hopewell Centre, KITEC and Panda Place, representing over 80% of
our owned property portfolio GFA. Electricity consumption is our
main source of carbon emissions which accounts for over 78% of
our calculated carbon footprint.
We have set up systems to monitor our consumption through
the implementation of environmental management systems and
conducting annual carbon audits.
The annual energy consumption of our properties (Hopewell Centre,
KITEC, Panda Hotel and Panda Place) was reduced by 18.96% in
2010/11 compared to 2007/08, of which 15.17% of the savings were
due to the replacement of air-cooled chillers with more energy
efficient water-cooled ones in the central air conditioning systems.
This initiative also led to important monetary savings in electricity
costs including 25% in KITEC and 40% in Panda Place. The remaining
energy savings were achieved through the installation of energy
efficient LED lighting and T5 fluorescent tubes. To further reduce
energy consumption in Hopewell Centre, we plan to replace all
old light bulbs with energy efficient ones by 2014. We have also
replaced the refrigerant used in our air-conditioning systems with
refrigerants that have a lower impact on global warming.
Other initiatives are in place to reduce energy consumption
throughout our buildings, such as upgrading passenger lifts and
adjusting the operating hours and modes of lighting and air
conditioning in common areas and offices.
We promote and raise public awareness on carbon reduction through
encouraging tenants to adopt energy saving designs in their fitting-
out works and operational practices.
Renewable Energy
Since 2008/09, we have initiated a research project to develop our
own large-scale vertical axis wind-turbine technology to meet the
global demand for clean, renewable electricity. A small experimental
turbine was built last year in Yangjiang, Guandong Province and a
new version has been refined and now built. The performance of
the new version is being tested and data been collected in order to
pave ways for the construction of a larger prototype in the future.
We also use small-scale renewable power wherever possible. For
instance, the surveillance cameras along the main road of Western Delta
Route are powered by a micro wind and photovoltaic hybrid system
and solar water heaters were adopted in the employee living quarters.
