i Light Marina Bay 2012 will once again be conducting the “Switch Off, Turn Up” Campaign, where stakeholders in and around Marina Bay are invited to switch off non-essential lighting whenever possible and turn up air conditioning temperatures to a comfortable 24 to 25 degrees during office hours. The energy efficiency campaign is designed to more than offset all the energy used by the 31 art light installations and associated power use in Asia’s first and only sustainable art light festival which runs from 9 March to 1 April.

The first edition in 2010 attracted 16 properties and saw collective savings of more than 41,000 kWh (kilowatt hours) of electricity over the three week event period, translating into saving 22 tonnes of CO2 equivalent. With 47 properties participating in this year’s campaign, energy savings of at least 200,000 kWh or 100 tonnes of CO2 equivalent are expected. This works out to more than four times the amount saved in 2010. To put it simply, the energy saved is enough to provide electricity for 762 4-room HDB flats for the same period.

The Singapore landmarks which are committed to reduce their energy use include very large properties like the prominent Marina Bay Sands – Prime Sponsor of i Light Marina Bay and the largest building to receive the Green Mark Gold award for its sustainability efforts – Marina Bay Financial Centre, The Esplanade, as well as properties under The Fullerton Heritage.

The campaign has also successfully extended its reach well beyond the Marina Bay precinct, with buildings across the island pledging their support. In addition, some buildings, which took part last time, have agreed to undertake additional energy efficiency measures and would encourage their tenants to do likewise.

For the 2010 lighting festival, City Developments Limited (CDL) involved four of its properties. It has taken the initiative this year to step up its commitment to introduce a total of 16 of its Singapore buildings into the “Switch Off, Turn Up” Campaign. Already a sustainability leader at home, CDL has made it for the third successive year onto the Global 100 Most Sustainable Corporations Listing, ranking at 62nd for 2012.
