Saving Electricity
We strive to implement measures to improve our
premises’ energy efficiencies. Our headquarters
in Hong Kong is classified as an Energy-efficient
Building under Hong Kong’s Energy-efficiency
Registration Scheme. In 2010, the building gained
its BEAM (Building Environmental Assessment
Method) certification, Platinum Grade (version
5/04) and more recently, we have been working
to achieve BEAM Plus certification. BEAM is Hong
Kong’s top tool for the assessment of a building’s
environmental performance from a full life-cycle
perspective.
We make every effort to reduce our consumption
of electricity. The large-scale introduction of LED
lighting in our customer centres, which resulted
in a two-thirds saving in electricity costs, is now
complete. In view of these positive results, LED
lighting is increasingly being introduced into
other areas of our operations, and we are currently
conducting a programme to install LED lighting in
carparks. Together with the ongoing replacement
of T8 lighting with T5 lighting, we saw an additional
saving of some 476,226 kWh of electricity at our
headquarters building during the year, lowering
our CO
2
emissions by a further 333,358 tonnes.
The use of high-efficiency induction lamps in our
warehouses has also brought in annual savings
of over HK$100,000 in electricity costs and
the reduction of 60 tonnes of greenhouse gas
emissions.
