KEY TARGETS - ENVIRONMENT
ENERGY
Environmental Impact
Depletion of fossil fuels, carbon emission to the atmosphere and high oil prices are both global and national concerns with economic and social impact, particularly its effect on climate change.
Performance Status
80% of Singapore’s electricity supply comes from natural gas. SP’s usage is mainly for air-con, lights, computers and teaching equipment. Gas consumption compared with electricity is low and use in food outlets and laboratory operations only. Energy management in the past was focused on upgrading to energy efficient technology, largely by optimising energy performance through redesign, control and automation with substantial investment in the redesigning of plants and control systems. In 2002, SP joined the open market energy procurement and by 2005 had secured lower electricity tariff and enjoyed cost savings through demand-aggregate procurement with other tertiary institution. However in 2006, electricity consumption was raised significantly above our set KPI target, mainly attributed to increased building space and activities and intensive operation of 24-hour clean room and other research facilities.
In 2005, we aimed to promote energy efficiency by encouraging broader participation and ownership. This was achieved through the launch of the 2007 SP ECO Office Challenge Award, designed to promote and reward departments with best green practices in their offices. It noted that the key efforts made by offices were focused on electricity saving through switching off lights, aircons, computers and equipments.
We have also developed SP Neutral Carbon Calculator to calculate our carbon footprint. More
Objectives & Targets - 2007 to 2010
Every effort counts towards conservation and as we continue to work towards maintaining the KPI target, some of our efforts will include:
| • |
Supporting national efforts to promote green electrical appliances and equipment through a systematic replacement programme and energy audit of the older buildings to ensure energy efficiency |
| • |
Investing in energy efficient buildings with BCA Green Mark award in new developments |
| • |
Promoting participation and ownership through SP ECO Office Challenge Award |
| 2005 – 2006 |
Financial Year 1 April 2005 to 31 March 2007 |

| Objectives & Targets |
Performance & Efforts |
| Electricity consumption - Maintain KPI at between 158 & 174 KWH/m2/year or 1974 & 2182 KWH/student/year. |
Met KPI set based on built up area in 2005 |
| Consumption peak in 2006 at 2487 KWH/student/year or 182 KWH/m2/year, and |
| exceeded KPI target by 14% and 4.5% respectively. |
| Awareness efforts made include SP ECO Office Challenge Award promoting conservation. |

| Objectives & Targets |
Performance & Efforts |
| SP SAVE POWER was aimed to establish and maintain an effective Energy Management System through energy efficiency. |
Energy efficiency improved by April 2002 through:
| • |
Stopping 24-hour chiller operation |
| • |
Optimal scheduling of chiller plants |
| • |
Control of lights & fans in foodcourts by sensor |
| • |
Switching to energy efficient lighting. |
About 4% reduction achieved between 2000 & 2002. |
| Implement more energy conservation measures by September 2004. |
More measures were completed by September 2004:
| • |
Reducing pump size for chilled water and |
condensate water
| • |
Installing master switches in media classrooms |
| • |
Control of lights & fans in toilets by sensor |
| • |
‘Switch Off‘ when not required - air-con, lights & computers. |
However, consumption rose by about 2% a year from 2002 to 2004 due to increase in activities. |
| Set benchmark on use of electricity |
Normalisation rate at 2078 KWH/student/year [based on 5-year data per capita of students] or 166 KWH/ m2/year [based on GFA]
KPI set to maintain normalised consumption levels within 5%:
Between 158 & 174 KWH/m2/year or
Between 1974 & 2182 KWH/student/year |
