IntroductIon 1.2 THE WESTPAC GROUP ENERGY USE from 1 JuLy 2011 to 30 June 2012, the WestpAc Group used 799,412 GJ of energy WhIch Is 7.5% below our energy use (figure 2). this reduction is attributed to the sale of subsidiaries, energy efficiency works, relocation to more energy efficient tenancies and a reduction in fleet numbers. figure 2: WestpAc Group energy use figure 3: WestpAc Group energy split for 1/7/ /6/12 Energy Use (GJ) 900, , , , , , , , , Electricity Unleaded Petrol LPG (Transport) Diesel (Stationary) LPG (Stationary) Diesel (Transport) Natural Gas Commerical 36% Retail 34% Data Centres 17% Fleet 10% Off-site ATMs 2% Other 1% (RAMS, Hastings, Qvalent, BTIM) the majority of energy consumed by the Westpac Group is electricity (86% of the total energy use). unleaded petrol is the second largest energy source consumed (10% of the total energy use). this energy is used predominantly by our commercial offices and retail network as shown in figure 3. full details of the Westpac Group s environmental performance, including our carbon emissions, are included in the Annual review and sustainability report which is available on our website: 4

7 2. energy Assessments And opportunities 2.1 ABOUT THE ENERGY EFFICIENCY OPPORTUNITY PROGRAM the energy efficiency opportunities Act 2006 (eeo Act) Is A national LAW that requires AustrALIAn corporations Who use more than 500,000 GJ of energy per year to Assess their energy use And ImproVe energy efficiency over A five year period. It does this by requiring businesses to undertake energy assessments, identify and evaluate energy efficiency opportunities and publicly report findings each year. eeo assessments must address six key elements: 1. Leadership; 2. people; 3. Information, data and Analysis; 4. opportunity Identification and evaluation; 5. decision making; and 6. communicating outcomes. the eeo program is administered by the department of resources, energy and tourism (dret). for more information on the eeo program, refer to au/energy/efficiency/eeo. All ideas 1 identified through the energy assessment process, along with the business decision, costs and savings are recorded and tracked. Where feasible, ideas are subjected to additional technical review or additional information is sought, turning the idea into a costed opportunity 2. All opportunities are submitted to management for review and approval. opportunities are evaluated in terms of energy and maintenance savings, lease conditions, business benefits such as staff comfort, productivity and occupational health and safety and alignment of the opportunity with the Westpac Group business, sustainability, property and technology strategies. opportunities identified as not to be implemented are reviewed from time to time as energy prices, business priorities and change in the economic climate occur. regular reporting of the outcomes of energy assessments, energy performance, savings achieved from energy efficiency works and business decisions is provided to the board, senior management, operational staff and other key stakeholders on a monthly, quarterly, annual and ad hoc basis. full details of how and when we will carry out assessments are contained in our Assessment and reporting schedule. the Westpac Group has allocated personnel and budget to improve the energy efficiency of our facilities. the Group undertakes comprehensive energy assessments for all energy uses within the facility, including analysis on how and where energy is used, energy trends over time, performance indicators, influences on energy use, assessment of major energy using equipment and processes and identification of cost effective energy efficiency opportunities. A range of people are involved in the energy assessment process, including internal subject matter experts, branch managers, our sustainability champions, service providers, facility managers, consultants, contractors, and other personnel who influence energy use. 1. An idea is a potential change to a system, process, activity, technology or piece of equipment that is intended to improve energy performance, and has not yet undergone technical or whole-of-business evaluation. 2. An opportunity is a potential change to a system, process, activity, technology or piece of equipment that may result in improvements in energy performance with a payback period of 4 years or less. It is generally supported by more detailed information such as quotes or proposals. 5

8 2. energy Assessments And opportunities 2.2 WESTPAC GROUP ENERGY ASSESSMENTS the WestpAc Group Is In Its first 5 year program cycle And must Assess 80% of the Group s total energy use. to meet the 80% energy assessment requirement, the Westpac Group will assess: commercial offices to a Level 2 energy Audit standard (as per As3598:2000). the rams head office to a Level 2 energy Audit standard (as per As3598:2000). data centres to a Level 2 energy Audit standard (as per As3598:2000); and retail network using representative assessments: sixty branches will be assessed to a Level 3 energy Audit standard (as per As3598:2000); seven business banking centres will be assessed to a Level 2 energy Audit standard (as per As3598:2000). combined, these facilities represent 87% of the Westpac Group s total energy use from 1 July 2011 to 30 June due to the large number of branches and business banking centres, the Westpac Group uses representative assessments. representative assessments analyse energy consumption and identify energy efficiency opportunities for a small population of facilities which are representative of the whole group. the findings can then be extrapolated across the broader group. the use of representative assessments has reduced the number of retail assessments from over 1,160 to 67 resulting in cost and time savings for the Westpac Group. much of the activity in the past 12 months has focused on commercial office and data centre energy assessments as shown in table 1. the next twelve months will see the completion of commercial office assessments, ongoing assessment of retail sites, evaluation of energy efficiency ideas and opportunities and implementation of approved energy efficiency initiatives. the Westpac Group has completed 26 energy assessments over the last two years, covering 380,974 GJ of energy or 48% of the Westpac Group s total energy consumption (table 1). these assessments have identified 506 energy efficiency ideas, 288 of which have been developed into energy efficiency opportunities with potential energy savings of 90,778 GJ (table 2). of the identified opportunities: 91 have or will be implemented saving 61,306 GJ of energy per annum; 140 require further information before a decision is made; and 57 opportunities will not be implemented as they do not meet eeo and/or Westpac Group business requirements. 6

11 figure 4: potential savings And payback Potential Energy Savings (GJ) 70,000 60,000 50,000 the majority of energy efficiency opportunities (approximately 65%) have a simple payback of less than 2 years as shown in figure 4 and most of these opportunities have or will be implemented. the Westpac Group may implement an opportunity with a simple payback of more than 4 years based on a whole of business analysis, eg occupational health and safety requirements, testing new technology, opportunity aligned with business requirements, energy efficiency is a side benefit of a broader project or the project is bundled with a series of other projects which have a shorter payback. Likewise, the Group may decide to not implement an opportunity with a payback of less than 4 years where the opportunity does not meet business requirements. figure 5 shows the types of energy efficiencies identified: It works include decommissioning servers, activating energy saving settings on computers and printers and implementing an automatic shut down program for computers. these works account for 30% of potential savings. heating, ventilation and air conditioning (hvac) works including upgrading or replacing air conditioning plant, installing variable speed drivers, modifying set points, using economy cycle and demand based ventilation. these works account for 25% of potential savings. Lighting projects including energy efficient lights, timers and sensors and account for 21% of potential savings. management / behaviour opportunities include behaviour change programs, energy efficiency requirements in procurement policies, benchmarking, monitoring and verification, reporting and aligning procedures with international and Australian standards. these opportunities account for 18% of potential savings. 40,000 30,000 20,000 10, YEARS Implementation Under Investigation Not to be Implemented Potential Energy Savings (GJ) 30,000 25,000 20,000 15,000 10,000 5, YEARS figure 5: types of opportunities IdentIfIed 4+ YEARS IT HVAC Initiative Type Lighting Management/ Behaviour Other Implementation Under Investigation Not to be Implemented 9

With consideration of maintenance savings, the works will achieve a payback within 2 years. figure 6: energy savings from A LIGhtInG upgrade At 35 pitt st sydney ELECTRICITY USEAGE (MWh) JUL AUG SEP OCT NOV DEC JAN FEB MAR APR MAY JUN 2010/ /

13 3.2 BUILDING TUNING PROGRAM equipment type Business response energy saved (GJ) Greenhouse gas abated (co2-e) Dollars saved payback period building management system (bms) Implemented 576 GJ 109 tonnes $25,000 per year Immediate As part of the eeo assessment process and a broader collaboration between facility managers (fms) and sustainability managers, fms are encouraged to monitor the environmental performance of their sites and identify opportunities for improvement. In november 2011 the on-site fm at 7 Laffer drive bedford park undertook a building tuning program which involved modifying the operating hours of the air-conditioning system to better align with the hours staff worked and adjusting temperature set points and unit control to ensure consistent heating and cooling through the facility, preventing units from fighting each other in different modes or at different times. these adjustments have resulted in a 5% reduction in electricity per annum at the site with no capital cost to the Westpac Group. figure 7: energy savings from A building tuning program At 7 LAffer drive bedford park ELECTRICITY USEAGE (MWh) JUL AUG SEP OCT NOV DEC JAN FEB MAR APR MAY JUN 2010/ /

14 3. case studies 3.3 LIGHTING UPGRADE 360 COLLINS ST MELBOURNE equipment type Business response energy saved (GJ) Greenhouse gas abated (co2-e) Dollars saved payback period Lighting not to be Implemented 659 GJ 221 tonnes $22,000 per year 3.6 years An eeo Assessment at 360 collins st melbourne identified a number of energy efficient lighting opportunities, including installing occupancy sensors in open plan office space. Lighting in the Westpac Group tenancy at 360 collins st is divided into eight zones per floor. Installation of occupancy sensors in each zone would allow lights to automatically switch off when the space is not being used. this initiative could save approximately 659 GJ of energy and $22,000 in energy costs per year. however this project will not be implemented due to the payback exceeding lease tenure.
