SUSTAINABILITY REPORT
CASE STUDY
OUR
GREEN MARK-
CERTIFIED
BUILDINGS
We constantly explore ways to minimise
the carbon footprint arising from our
operations and have a total of seven
buildings that have been accorded
Green Mark status by the Building and
Construction Authority (BCA) in Singapore.
These include our headquarters,
OCBC Centre (pictured to the left), which
is the oldest historic site in Singapore to
achieve the Green Mark Gold certification.
OCBC Centre was completed in 1976 but
extensively retrofitted in 2011, which
reduced its annual consumption of
electricity by about 2.7 million kWh and
of water by 17,000m 3 . We also successfully
renewed the Green Mark certifications
for OCBC Tampines Centre One and
OCBC Tampines Centre Two in 2017.
GREEN MARK PLATINUM STATUS AWARDED TO OUR DATA CENTRE
In 2017, we completed the construction of a data centre that was certified with the BCA-IMDA Green Mark Platinum
Award – the highest standard achievable in Singapore. Utilising water-based cooling systems and cold-aisle containment
technology that significantly reduce the energy required for cooling, as well as a diesel rotary uninterruptible power
supply system (pictured below) that ensures efficient power usage, the data centre is 30% more energy efficient than
other standard data centres in Singapore and the rest of the region. The amount of energy saved will result in about
S$500,000 in cost savings per year.
