  • 5. Improving Energy Efficiency in existing facilities Westmead Hospital Lighting & Controls Upgrade (Contractor – Total Energy Solutions) – Scope • 12,798 light fittings upgraded • Dimmable LED downlights in Lecture Theatres saving up to 80% electricity. • Phillips Dynalite Lighting Control – 4,000 lights controlled by occupancy sensors – savings yet to be verified but estimated at > 25% of consumption of the lights controlled. – Controls mainly Corridor lights • Upgrade of emergency lighting (EXIT lights) – Capital Cost $3,728,765 – Long life lamps (75,000 hours) or 8 years – Completed January 2014 5
  • 6. Improving Energy Efficiency in existing facilities Westmead Hospital Lighting Controls Upgrade • Control of 4000 Corridor lights 3 different schedules identified – Patient care areas – Public areas – Office areas (8am – 6pm) 6
  • 7. Improving Energy Efficiency in existing facilities Westmead Hospital Lighting & Controls Upgrade Outcome • Lighting Upgrade Savings – 3317 megawatt hours saving (calculation using measurement & deemed operating hours – $480,000 p.a. • Lighting controls upgrade – Estimated savings ~ $50,000 p.a. to be verified 7
  • 8. Improving Energy Efficiency in existing facilities Air Conditioning Plant Upgrade Contractor - Dalkia – 2 x 4000kW high efficient TRANE chillers • Supplies 90% of the air conditioning (cooling) for Westmead Hospital • 30% savings on electricity – 10 new energy efficient pumps installed with variable speed drives – 2 new cooling towers installed – Total Capital $2.2 million – Completed November 2012 – Fine tuning of controls ongoing 35 year old CARRIER replaced New variable flow TRANE chillers 8
  • 9. Improving Energy Efficiency in existing facilities Air Conditioning Plant Upgrade Outcome • Chiller Upgrade – verified 2580 megawatt hours p.a. or $375,000 p.a. savings • Automatic controls and pumps upgrade – in process of fine tuned but likely to be > $140,000 p.a. 9
  • 10. Feasibility of Embedded Solar Generation in Hospitals Future Projects Solar Photovoltaic • Pilot Project - 10kW Photovoltaic Installation – to supply Westmead Education Conference Centre ~ saving verified $2,200 p.a. • Today’s cost of 10kW system ~ $18,000 • Payback ~ 9 years 10
  • 11. Feasibility of Embedded Solar Generation in Hospitals Solar Photovoltaics Opportunity for hospitals • Peak output of Solar PV coincident with Peak Demand of Hospitals • Lots of roof space • Can utilise all in house not dependent on feed-in tariff Source: http://reneweconomy.com.au/2014/will-iea-and-governments- be-the-last-to-discover-solar-pv-revolution-80280 11
  • 12. Feasibility of Embedded Solar Generation in Hospitals Solar Photovoltaics Opportunity for hospitals • Ideal of Car Parks and covered walkways. • Can be used to mitigate additional electrical infrastructure costs by reducing maximum demand (e.g. may be able to forego upgrade of substations and cables.)

  • 13. Feasibility of Embedded Solar Generation in Hospitals Business Case for Westmead Hospital 1000 kW Solar PV system • Capital ~ $1.8m • Output ~ 1,300 megawatt hours or 2.7% of site • REC Certificates generated 1200 p.a. • Income • Savings Grid Electricity ~ $195,000 p.a. • Value of RECs @ 30ea = $36,000 • Total $231,000 p.a. • Simple Payback ~ 8 years • 3,800 panels covering 6,100sqm or ~ 10% of gross area of roof space. 13
  • 14. Feasibility of Embedded Solar Generation in Hospitals? Risks Renewable Energy Certificates • Large Generation Certificate (LGCs) price falling due to uncertainty around Liberal Government’s review of the Renewable Energy Target. 14
  • 15. Empowering Staff to Reduce Office Consumption Empowering staff to reduce office consumption •Estimated Office consumption > $1 million per year (20%) •Inspiring staff to save Office Energy – 3 determining factors – Identify Energy Champion in the department to drive efficiency. – Feedback information about how we contribution to consumption • How much do computers, the office fridge, photocopiers, ice machines, Zip urns, and microwaves consume. Do your office lights remain on when unoccupied ? • Contribution of equipment standby power. – Simple Tool(s) to equip staff to make a difference 15 “Everything should be made a simple as possible but no simpler” – Albert Einstein.
  • 16. Empowering Staff to Reduce Office Consumption Empowering staff to reduce office consumption • The “plugwise” solution. – Controls everything in your office at the plug level – Provides daily and hourly consumption information of your site – Enables you to schedule equipment on/off – Lighting can be controlled by sensors. 16
  • 17. Empowering Staff to Reduce Office Consumption Empowering staff to reduce office consumption • The “Plugwise” solution. – Pilot Project – Westmead Hospital Asset Services. Project installed 15 Oct 2013 – 81 modules, on 54 Appliances – Lighting & Appliance Control with wireless intelligent switching, no rewiring – Minimal interruption during installation – Take control of wasted electricity and reduce energy consumption – Increase awareness and change behavior – Full control and Visibility and Easy Self Management – Payback around 3-6 years depending on scale of project and existing tariff rates 17
  • 18. Empowering Staff to Reduce Office Consumption - 2 weeks Lighting WITHOUT appliance control 18 Light being left on, no control
  • 19. Empowering Staff to Reduce Office Consumption - 2 weeks lighting with appliance control Lights OFF when NO occupation turning off more frequently
  • 20. Base Line 220 watts – Can be reduced significantly System left on when people have gone home – Can be reduced significantly Empowering Staff to Reduce Office Consumption - without appliance control - Aircon left on for extended periods
  • 21. Standby power removed, controlled with a Schedule Empowering Staff to Reduce Office Consumption Schedules Implemented to AC units
  • 22. Schedule Implemented Empowering Staff to Reduce Office Consumption -Actual Saving after schedules implemented
  • 23. Baseline as high as 308 watts over a weekend Empowering Staff to Reduce Office Consumption -Copiers always on with very high standby power
  • 24. Empowering Staff to Reduce Office Consumption -Copiers with Actual Schedules
  • 25. Planning Sustainability into New Facilities •How to improve the uptake of Sustainable Initiatives in new facilities – New hospital facilities mandatory 4 star rating • Currently nominal only – no need to undergo independent verification. – Project Management approach ignores legacy issues of existing infrastructure. • Continuing dichotomy between Capital and Recurrent. • Legacy issues of existing infrastructure considered responsibility of LHDs to fund out of recurrent budget. – Decision Makers need to enforce Sustainability into the agenda at very early stage • Increased investment in most energy efficient plant. • Quarantine capital for installing embedded renewable generation. 25
  • 26. Planning Sustainability in New Facilities New Development Case Study – Mt Druitt Hospital • Mt Druitt Hospital – chronic air conditioning shortage in summer months – need to main Chiller plant. • Business case focused on project outcomes, not whole of facility outcomes. • Instead of upgrading central chiller plant, packaged air conditioning units were installed to extensions in lieu of upgrading central plant. • Package units installed immediately above central chiller plant. • Upgrading central plant should have been identified at Project Definition Phase 26
  • 27. Planning Sustainability in New Facilities 27 •Lessons learnt – New Capital Projects offer a one in 40 year opportunity to get the building energy efficient – Retrofitting energy efficiency is both very expensive and logistically far more complex. – Need for holistic approach that uses business case covering long term operational costs of whole building – Need to be more specific in defining the energy efficient technologies to be installed in new projects. – Good space management and operational efficiency have major impact on energy and water efficiency.
