Our water consumption is measured in terms of kilolitres per internal square metre and considers the use of water by both occupants and equipment in a building. The intensity based water target was selected to match performance indicators used conventionally to benchmark water consumption in buildings. Table 3 sets out our future targets on water use.
|Target Year||Applicability||Target Water Consumption (kilolitres per sq metre per year)|
|2014||All buildings where Standard Chartered has control of water facilities||1.125|
In 2010, we achieved a 34 per cent reduction in water use in our GEMS buildings from 1.52 to 1.00 kilolitres per net internal area. This was equivalent to reducing water use per FTE by 21 per cent from 19 to 15m3/year.
This was achieved through a variety of new measures and water efficiency fixtures including:
We have ensured that environmental efficiency was incorporated not only when designing new offices, but is fully integrated in refurbishing existing buildings. For example, our branch in Bukit Timah, Singapore, occupied by Standard Chartered since the 1960s, was upgraded in 2010 and achieved a Watermark award for running a water efficient building.
In 2010, our Haddows Road, Chennai, complex in India achieved a LEED Gold Certification – an internationally recognised green building certification – and a 20 per cent saving in energy and water, leading to an annual cost saving of USD179,111.
To improve the building’s energy management, lighting was improved by replacing some of the older fluorescent tube lighting and metal halides with thinner, more efficient, T5 and Compact Fluorescent bulbs. To improve the efficiency of personal IT equipment, cathode ray tube monitors were replaced with Energy-Star related flat screens.
The complex now sources 85 per cent of its power consumption from Wind Energy through an external supplier. Using a renewable source of energy has contributed to an annual saving of 11,000 tonnes of carbon emissions and an energy cost saving of about USD600,000.
Meanwhile, a reduction of 20 per cent in water consumption was achieved through the adoption of measures such as rainwater harvesting, aerators in taps, drip-irrigation for landscaping, plus the re-commissioning of a sewage treatment plant to recycle water for use in landscaping and cooling towers. Waste reduction strategies included waste segregation at source, distribution of ceramic mugs to employees to reduce usage of paper cups, and e-waste recycling. We also increased the number of green spaces in the Haddows Road complex and introduced recycled paper cards and letterheads.
