This year, PETRONAS will participate in Earth Hour 2010, an international call for efforts in addressing concerns on global warming and climate change.
Come 27 March, PETRONAS will again be switching off for one hour non-essential lights at its facilities, including the PETRONAS Twin Towers, the Suria KLCC shopping mall, petrol stations and its other premises around the world. The lights at the premises in Malaysia will be turned off from 8.30pm to 9.30pm.
In conjunction with the event, PETROSAINS, a unit of PETRONAS, has partnered with World Wildlife Fund (WWF) on an Earth Hour 2010 awareness campaign. A mini-exhibition by WWF has been set up at the science discovery centre aimed at educating the public on the objectives of this effort to garner their support and pledge to switch off their lights during Earth Hour.
PETRONAS stations, particularly those located in suitable locations around the country, have also been advised to observe Earth Hour 2010 and switch off their non-essential lights during the event.
PETRONAS is also working together with the Federation of Malaysian Consumers Associations (FOMCA) to educate the public in becoming smart consumers through FOMCA’s National Consumer Campaign or Kempen Konsumer Kebangsaan (3K). The campaign seeks to nurture good and responsible consumer behaviours, including with regards to consumption of energy and other resources.
On its own, PETRONAS made a long-term commitment in 2007 through its Energy Loss Management (ELM) framework that sets out medium and long-term targets for reducing energy consumption and improving energy efficiency, including reducing greenhouse gas emissions, across its operations.
Details of the ELM efforts and results are available in PETRONAS’ Sustainability Report 2009

PETRONAS’ ENERGY CONSERVATION INITIATIVES
In support of energy conservation, PETRONAS implements a variety of energy saving initiatives at the PETRONAS Twin Towers and has been doing so since July 2008. These cover air conditioning, lighting, escalator systems and water heating systems.
For instance:
1 The set-point temperature for our air-conditioning system has been increased from 21-22° to a higher temperature of 23-24°C (depending
on headcount density)
2 Lighting is monitored and controlled by the Building Control System. There is an automatic lighting shut-off during lunchtime daily
(1.00-2.00pm on Mondays to Thursdays, 12.30-2.30pm on Fridays) and after 5.30pm
3 External lighting of the towers has been reduced by 50 per cent. Since September 2008, the operational hours for the lighting of the
PETRONAS twin Towers have been rescheduled from 7.30pm to midnight
4 All semi-enclosed and fully-enclosed rooms (e.g. meeting rooms, manager’s offices and pantries) have been fitted with motion sensors that
switch off lights automatically when the rooms are unoccupied
5 Escalators at the Sky Lobby of level s 40 - 43 are operated with Escalator Speed Control motion detectors
6 All hot water heaters are switched off automatically at 8.00pm
Prior to implementing these energy saving measures, the average energy usage for each Tower was approximately 2.6 million kWh per month at PETRONAS occupied floors. Since the introduction of these measures, there has been a seven per cent reduction in energy consumption from August - December 2008, compared to the same period in 2007. The increase in the air conditioning set-point temperature of 1-2°C has produced a monthly savings of six per cent refrigerant tonnes per hour (RTH) for chilled water consumption.
KLCC
KLCC utilises a Gas District Cooling (GDC) system, which supplies chilled water for air-conditioning as well as electricity for the entire KLCC development. Natural gas is the primary energy source, and its efficient use is greatly enhanced by technology that recovers exhaust heat from the gas turbines to produce steam and chilled water.
The system’s utilisation of clean-burning natural gas helps to minimise noxious emissions. In addition, it uses refrigerants that do not cause ozone-depletion. By centralising the chilled water and electricity-generating facilities for a district within one building, the GDC system minimises pollution from the ‘cooling water drift’ of chemically treated water escaping from individual cooling towers
The system also helps to conserve our finite natural gas resources by maximising fuel efficiency and minimising waste.
