Introduction Why Energy Benchmarking
Customer needs - DC is Energy Intensive - Keen to save energy cost - Premium customer service
World trend in energy saving - Benchmark with peers - Facilitate ldquoBehavior Changerdquo - Interactive productservice
CLPrsquos commitment in pursuing green - Responsible energy provider - Driving energy efficiency - Benchmarking tools in place
- Eco-Optimizer (Domestic) - Energy Billboard (RetailSMEs)
CLPrsquos unique position - Independent position facilitates data
amp insights collection - Follow up with individual DC by
dedicated account managers

Methodology
Data Collection by Questionnaire bull Respondents were asked to submit data relevant to their
energy consumption and bull Describe their energy management initiatives
Data Analysis Verification and Insight Collection bull Telephone calls and meetings were conducted to verify
reported data bull Following initial analytics top performers were interviewed
to understand their best practices (mainly facility load)
Energy Benchmarking Report for Individual DC Customer bull CLP Account Managers visit individual customer and present
the findings bull CLP can also offer energy audit services
DC energy benchmarking is a complex exercise as there are many factors affecting
DC energy efficiency The service will be developed in stages we start with quick win items (eg PUE comparison) to build the momentum with customers
5
Road Map of New Energy Benchmarking Service
Measurement Base lining
Stage ONE Stage TWO
bull Understand their energy performance amongst peers
bull Learn the best practices
Value to Customers bull Individual report
bull Face to face discussion bull Invite more Data Centres to
join
Result discussion Sharing of best practices in industry Collect more data and enhance the service

Real Life Saving Examples bull Case 1 25 to 29 deg-C 14 saving Practically FREE of cost bull Case 2 20 to 25 deg-C 22 saving Practically FREE of cost
Considerations bull Gradually increase 1 degree at a time bull Risk mitigation measures (1) consult with vendor (2) critical spares stored on-
site amp shortened time for fault handling (3) more temperature sensors bull Hurdle to overcome educate end-use customers change SLA terms bull New trend for Colo DC Market a DC hall as ldquoGreen Zonerdquo with higher
temperature setting in SLA and share the benefits with end-use customers
Industry average = 224 deg-C New equipment can operate at gt35 deg-C
14
Real Life Saving Examples bull Case A Plastic sheets to shield off cold aisle
PUE = 16 payback = 1 year bull Case B To install high grade glass wall expected
saving 8 on chiller payback = 4 years
B) Cold Aisle Containment Before After
Considerations bull Best for high power density zone where cooling demand is
highly concentrated [eg IT density gt 6kWrack] bull Glass wall containment is ideal for new project Can consider
plastic sheet shield-off for retrofitting projects
Short circuit Short circuit
15
Methodology 1 Install sensors for one-off or continuous
monitoring identify hot amp cold spot 2 Optimise flow rate by reducing fan speed
of CRAC OR install boosters amp dampers so that some CRACs can be shutdown
C) Air Flow Balancing Management
Real Life Saving Examples bull Case 1 measure bi-annually 6 saving on reduced CRAC output payback = 8
months bull Case 2 install boosters and dampers shutdown of some CRACs payback = 4
years
Considerations bull Maintenance issues for additional boosters amp dampers bull Rebalancing on regular basis (cater IT load growth) bull New trend dynamic system
16
IT load initiatives bull Server virtualisation and switch off idle servers to reduce peak bull Replace energy efficient IT equipment (difference in consumption 25)
D) Improve Load Factor
Considerations bull Follow regulations from WSD amp EPD (Please approach CLP welcome to
share our experience with you)
Facility load initiatives bull Case 1 Water mist spray to air-cooled evaporators reduce 10 peak load bull Case 2 Optimise chiller sequencing reduce 10 peak load
