PLENARY SESSION 2 Making Energy Efficiency Sustainable

Speakers: Peter Halliday (Siemens), Harsh Choudhary (McKinsey), Vinod Kesava (TGAG)

Moderator: Mr Nilesh Jadhav (ERI@N)

• To sustain momentum of change, organization needs to be committed towards

sustainability with staff involved from all levels of the organization.

• Energy KPIs need to be closely monitored and further translated into one that staff

can comprehend to align movement on EE transformation.

• Integrative design process (IDP) is the key to designing sustainable EE solutions. As

compared to traditional piecemeal approach, such whole system approach

maximizes energy savings.

• Opportunities for IDP are the highest at the early design stage. Cost of change

increases as the project moves towards the later development stages.

BREAKOUT TRACK 1A Case Studies in Energy Management

Excellence Part 1

Speakers: Mr Muthusamy Ravichandran (Nestlé), Mr Andre Van Schuijlenburg (APB)

Moderator: Mr Ken Hickson (SASA)

• Top management support required and clear vision and roadmap for the energy

management system to drive EE efforts

• Establishment of a cross-functional energy management team to identify energy

saving opportunities across the organisation

• Establishment of a energy savings culture amongst the employees by changing

the employees’ mindset and behaviour through training and communication

efforts

• Regular employee discussions to generate energy saving ideas and rewards for

recognition of employees’ EE efforts

7

PLENARY SESSION 3 Energy Management Information Systems

Speaker: Ms Malavika Bambawale (Accenture), Ms Li Huishi (KBC)

Moderator: Prof Toh Kok Chuan (NTU)

• Energy Management Information System (EMIS) is essential in helping organisations

visualise and track their energy usage, monitor performances and seek out

opportunities to improve EE

• It transforms data captured in physical devices into useful information, and facilitates

plant information flow to the appropriate end-users, which includes the operators and

management of the company

• In order to implement EMIS, companies need to understand their objectives, the type

of information, functionality of the system required and the users of the systems

8

PLENARY SESSION 4 Energy Efficiency Financing

Speakers: Mr Glen Plumbridge (SDCL), Mr Harvey Koenig & Mr Rahul Kar (KPMG), Ms Kavita Gandhi (SEAS)

Moderator: Mr Shiva Susarla (ESI)

• Incentives are available to help companies – e.g. Productivity & Innovation Credit

(PIC) scheme offers support for a wide range of R&D efforts in design and testing of

technological and engineering projects.

• EE financing looks to address many of the barriers, e.g. information, expertise,

performance risk and capital. However, the corporate commitment to act remains as

the key barrier.

• Suitability of financing model for Singapore will be dependant on the risk sharing

appetite of the stakeholders.

• 3 top considerations for financing EE projects – credit risk, quality of technology

provider, and structure of cooperation. For SMEs and smaller ESCOs, project

structure and transaction needs to be simplified. Credit risks can also be reduced

through bundling of projects.

BREAKOUT TRACK 3A Setting up a Sustainable Energy

Management System

Speakers: Prof Toh Kok Chuan (NTU), Mr Thomas Tan & Mr Joseph Mok (Kim Heng Offshore & Marine)

Moderator: Mr Kamal Soundararajan (ESI)

Global Momentum of Energy Management System

• ISO 50001 is adopted by most industrialized countries

• A suite of ISO standards is being developed to complement ISO50001; provides

guidance for organizations to implement Energy Management System

• ISO standards are complementary with the requirement of the Energy Conservation

Act (ECA) and provide guidance for ECA compliance

10

BREAKOUT TRACK 3A Setting up a Sustainable Energy

Management System

Speakers: Prof Toh Kok Chuan (NTU), Mr Thomas Tan & Mr Joseph Mok (Kim Heng Offshore & Marine)

Moderator: Mr Kamal Soundararajan (ESI)

Implementation of ISO 50001 by industry

• KHMO has demonstrated that industries can benefit from the implementation of ISO

50001- better energy use management, improve profit margin etc.

• To establish an energy management system, it is important that the entire

organisation support the notion and works together in establishing it.

• As more players in the same industry implement ISO 50001, everyone can benefit

from the lessons and experiences shared.

11

BREAKOUT TRACK 4A Energy Management in Organisations

Speakers: Mr Yee Chow (Accenture), Mr Yap Chee Peng (3M)

Moderator: Mr Chong Teng Sheng (NEA)

• Determine energy management interventions going forward by understanding where

you are now

• Drive energy management in structured and holistic manner- from strategy to

execution

• Comprehensive measurement through information systems underpins Enterprise

Energy Management

• Important for corporate values to form foundation for sustainability efforts

12

BREAKOUT TRACK 1B Best Practices in Energy Efficiency

(Optimisation projects)

Speakers: Mr Kaisar Hassan (EXXON), Mr Jacky Chaberty (SOXAL)

Moderator: Ms Tan Li Yen (NEA)

Optimisation projects can be simple and require little capital expenditure, but result in

significant energy savings

Plants that were designed efficiently can become inefficient due to changes in

customer demands and product line changes

Such opportunities can be uncovered by system – level energy metering and

benchmarking by company or by system

EE should be incorporated in piping design to reduce pumping energy (e.g. no sharp

bends, wider pipes).

13

BREAKOUT TRACK 1C Energy Efficiency in High Technology

Facilities – Laboratories and Cleanrooms

Speakers: Mr Gordon Sharp (Aircuity, Inc.), Ms Danielle Marie Griego (ERI@N), Bharath Seshadri (ERI@N)

Moderator: Ms Melissa Low (ESI)

• Laboratories have the potential to reduce air change per hour (ACH) by utilizing

demand-based control for lab HVAC and enthalpy wheel for room exhaust.

• Laboratories and high technology facilities are unique building type with specialized

indoor requirements. Legislation and incentive schemes currently do not cover these

unique facilities.

• The ability to analyze data from a sea of information is critical for EE improvement.

• Working with contractors without relevant experience and knowledge in EE is seen as

a barrier, which will need to be addressed.

• I2SL was discussed as a knowledge platform, from which stricter standards on EE in

laboratories can be derived.

14

BREAKOUT TRACK 2B Best Practices in Energy Efficiency

(Installation of tri-gen & waste heat recovery)

Speakers: Mr Chew Siou Ping (GSK Vaccines), Mr Ang Kwok Lek (APB)

Moderator: Mr Kwong Kok Chan (Senoko)

• To maintain a load factor of 90% during day and night, the tri-generation system

should not be sized to the peak demand

• Projects were supported by top management and implemented by the operation team

• System and product reliability issues have to be addressed

15

BREAKOUT TRACK 2C Energy Efficiency in High Technology

Facilities – Data Centres

Speakers: Mr Ed Ansett (i3 Solutions), Mr Ryan Ngei (3M)

Moderator: Mr Arvind Verma (IDA)

The Datacentre Waterfall

• There is need for datacentre metrics for facility and technology infrastructure as well

as software.

• Energy losses cascade over various datacentre sub-systems (e.g. software, physical

IT, logical IT and facilities).

• Facility losses comprises non IT equipment such as power and cooling systems. IT

equipment losses comprise storage, network, compute equipment and software use.

• Examples of likely technology successes in Singapore include fuel cells, low power

servers, immersive cooling, refrigerant cooling and multiple tier datacentres.

16

BREAKOUT TRACK 2C Energy Efficiency in High Technology

Facilities – Data Centres

Speakers: Mr Ed Ansett (i3 Solutions), Mr Ryan Ngei (3M)

Moderator: Mr Arvind Verma (IDA)

3M’s Liquid Immersion Cooling reduces 45% of Electrical Bills Data Centres

• The liquid immersion cooling method is more efficient (energy and capital) than

traditional cooling methods as volumetric heat capacity of liquid is higher than gas

• Cooling occurs when 3M’s engineered fluid (Novec) absorbs heat from the CPU and is

converted from liquid to gas

• Advantage of 2 phase liquid immersion cooling include high efficiency (high cooling

capacity due to latent heat of vaporization), high density (ability to stack IT equipment)

and simplicity

• Power usage effectiveness of 1.05 (from 2.0) is achievable

17

BREAKOUT TRACK 3B Best Practices in Energy Efficiency

(Heat Recovery/ Heat Recovery)

Speakers: Mr Norman Lee (Actsys), Mr Lee Thompson & Mr Peter Stulen (Hertel)

Moderator: Mr Kwek Chin Hin (NEA)

• When implementing an energy recovery system, it is always better and cheaper to

include it right from the beginning in the design stage.

• Retrofitting carries greater risks – components have to be installed very close to the

existing plant, some potential measures things could be omitted because of

constraints from existing system.

• To assess the economic feasibility of implementing an energy recovery system, one

needs to know the expected efficiency of the recovery system and note the operating

conditions which are dynamic and fluctuating (e.g. the ORC system which converts

waste heat to power in a steel mill).

18

BREAKOUT TRACK 3C Energy Auditing Case Studies Part 1

Speakers: Mr Norman Lee (Actsys), Mr Lee Thompson & Mr Peter Stulen (Hertel)

Moderator: Mr Kwek Chin Hin (NEA)

Troubleshooting Excessive Energy Consumption of a Poorly Performing Process

• Energy audits should identify poorly performing process equipment

• Replacement of expensive process equipment is not viable before full depreciation –

need to improve their performance by corrective maintenance

• Companies can identify energy losses as a result of degradation, and re-instate them

to new and clean performance

• Analytical techniques, such as heat and mass balance, can be useful in determining

the true sources of energy losses

• Degradation of equipment can cause significant loss in energy efficiency

19

BREAKOUT TRACK 3C Energy Auditing Case Studies Part 1

Speakers: Mr Norman Lee (Actsys), Mr Lee Thompson & Mr Peter Stulen (Hertel)

Moderator: Mr Kwek Chin Hin (NEA)

Climate Protection and Rapid Payback

•Significant savings can be achieved through improvement and installation of thermal

insulation.

•A study conducted by McKinsey & Vattenfall found that the average payback period for

thermal insulation improvement projects in Europe was expected to be 3 months.

•Thermographic inspection and analysis can help in early detection of energy losses as

a result of poor or lack of insulation.

20

BREAKOUT TRACK 4B Best Practices in Energy Efficiency

(Process Chillers & Chilled Water System)

- Energy and cost saving

- Reduction of Global Impact (No refrigerants, reduce Brine)

- Process Advantage (Dynamic, quick response)

- Small equipment footprint

• Limitation

- Applicable to small capacity usage

Greening the Concrete Jungle

• Replacement of air-cooled chiller to water-cooled chiller at Acer Building

• Substantial annual energy saving of 1.8 mil kWh with payback period of 4 years (6-7

years without Greet Fund by NEA)

• Lifecycle cost saving are much higher due to reduction in maintenance cost

21

BREAKOUT TRACK 4C Energy Auditing Case Studies Part 2

Speakers: Mr Chee Chi Keong (G-Energy Global), Mr Lim Say Leong (ABB)

Moderator: Mr Roland Tan (NEA)

• Energy cost constitutes the greatest stake in the overall life cycle cost of

industrial equipment/systems.

• It is important to understand the energy profile and the operational behaviour of

the systems before recommending any potential EE improvements

• In project implementation, one of the common challenges is to identify a suitable

measuring point so that energy savings can be accurately calculated and

validated from the projected energy savings

• Common EE solutions such as VSD can achieve greater energy savings with

the advancement of technology in terms of its hardware and software
