Public Sector Taking the Lead
in Environmental
Sustainability
PSTLES FORUM
Ng Wee Hia, Assistant Director (Climate Change), MEWR
23 April 2010
Rationale
• Why Public Sector should take the lead:
– Carbon and resource constrained economy
– Reap cost savings
– Influence wider action by private and people sector
– Not affected by split incentives and can afford longer
payback periods
– Public expectations for government to demonstrate
leadership on efficiency initiatives
FCM measures
• Environmentally sustainable measures
– Energy efficiency Public Sector Taking The Lead
– Water efficiency Energy Water Waste
Energy Audits
– Waste minimisation

Environmental Scorecard • Electricity consumption - FY06: 2,080 GWh – 5.8% of national electricity consumption - FY07: 2,266 GWh (8.9% increase) - FY08: 2,383 GWh (5.2% increase) – 6.3% of national electricity consumption
Environmental Scorecard • Water consumption - FY06: 15.29 mil m3 - FY07: 15.46 mil m3 (1.1% increase) - FY08: 15.68 mil m3 (1.4% increase)
Energy Efficiency
• To undergo Energy audits
– By FY11: Existing buildings with central air-
conditioning systems and more than 10,000m2 air-
conditioned floor area
– By FY12: Infrastructure facilities
Cost of measures: $130k to $1.4m
>$4.5m
annual savings Average payback: 4.5 years
Savings: 3% to 33%
Energy Efficiency
• Energy audits
– Adoption of the Guaranteed Energy Savings Performance
Contracting Model (GESPCM)
• The Energy Services Company (ESCO) carries out the energy audit
and implements the measures
• ESCO guarantees annual savings that the building will realise over
a 5-year period as well as the Return on Investment (ROI)
• MOM Building and Treasury Building
• Energy monitoring and reporting
- Separate reporting for data centres with more than 1,000 m2 floor
area from FY09 onwards
- Fusionopolis and National Library Building (separate energy
meter)Energy Efficiency
• Air-conditioning
– All buildings with central air-conditioning and more
than 10,000m2 air-conditioned floor area to:
• Install instrumentation to monitor and report the COP of their
air-conditioning plants
• Achieve a COP of at least 4.7
• Achieve a COP of at least 5.4 when retrofitting chiller
systems
Cost of measures: $100k to $2.6m
$88k - $339k (based past projects)
annual savings
Payback: 1 - 8 yearsEnergy Efficiency
• Ambient indoor air temperatures
– All public sector premises to maintain the temperature
at 24°C or higher.
– Increase of 1°C in the air-conditioned indoor room
temperature reduce air-conditioning electricity consumption by
3%
• Energy Smart
– Existing large office buildings with central air-conditioning
and more than 10,000m2 air-conditioned floor area:
within two years of energy audits
– New buildings: within two years of operation
– Environment Building, MFA Building, MOE Building,
DSTA Tower A, National Library Building, Treasury,
Tourism Court, CPF Building (Robinson) and MOM
BuildingEnergy Efficiency
• ICT equipment
– All new office ICT equipment to meet latest ENERGY STAR standards
from FY09 onwards
Expected $30m savings
over a period of 3 years
– Green Procurement extended to include appliances from FY10 onwards
Appliance Lifecycle Costs
0-tick 4-tick
Refrigerator $3,720 $2,299
Air-conditioner $12,276 $6,450
• Energy Management Training
– Energy manager to oversee the management of energy consumption
and develop energy efficiency improvement plansWater Efficiency
• All agencies to participate in the 10% Challenge
• Buildings owned by agencies to be certified as Water
Efficient Buildings by FY10 – 564 buildings certified
Cost of measures: Less than $1k
$5k annual savings (for building with about 50,000m2
GFA, which consumes about
48,000m3 of water annually)Waste Minimisation • All agencies to implement recycling programmes at their premises by FY09 – E.g. paper products, aluminium cans, toner cartridges – 57 agencies have implemented recycling programmes
Other Measures
• Eco-Office
– All agencies to achieve the Eco-Office Green
Office Label by FY11
– MOM, NEA, PUB, NParks, Republic
Polytechnic and MEWR
• Green Mark
– New public sector buildings with more than
5,000m2 air-conditioned floor area: Green
Mark Platinum
– National Library Building, Nanyang
Polytechnic and Republic Polytechnic
– Existing buildings with more than 10,000m2
air-conditioned floor area: Green Mark GoldPlus
by 2020Environmental Scorecard
• Environmental scorecard
– All agencies to provide annual progress updates on
their environmental sustainability efforts by 31 May 11
– Online reporting system for use from FY10
– From FY11 onwards, all ministries and organs of
state to provide an overall energy savings target for
their family of agencies for the period FY11-FY13Energy Savings Target
– All ministries and organs of state to provide an overall
energy savings target for their family of agencies from
FY11
• Target should be able to achieve energy savings that would
keep aggregate energy consumption at FY09 levels, or
better, by FY13.
• MOM Building – 10.2% reduction in energy consumption or
annual cost savings through implementation of energy
efficiency measures identified in energy audit
• Treasury – $260k in annual cost savings through
implementation of energy efficiency measures identified in
energy auditEnergy Savings
