3. ‘Team Green’

4. GCCAM Web page & summary

5. £500k expenditure to replace rotten sash windows

6. Energy Awareness Campaign • Appointed ‘NIFES’ following their successful campaigns at UHB & N Bristol • £15-£20k fee but expected to save £200k • Formal launch in April with Board backing • Every department will have EARs ! • Significant corporate investment in energy conservation schemes – now need to concentrate on ‘good housekeeping’ efforts • Staff are responsive and recognise need

7. LED lighting

8. Recycling schemes • Since October 2010, all 18 Theatres have increased their recycling output by 200kg/week through waste segregation • Yellow bags replaced with orange – major benefit • NPAG: ‘the RUH are best achievers for recycling in the UK’ • Increased savings £40/tonne cf £89/tonne give annual saving in Theatres alone of £60k. • Black bag waste compactor now emptied 1-2 times /week cf 3 times/week saving £10k pa in haulage fees • Exemplar for other depts across the hospital • Procuring recycling bins for majority of depts – do we need ‘waste paper bins’? • Drink recycling bins installed at refreshment points • Baling and compacting of all black bag waste • Details on ‘Team Green’ website

9. Recycling points at key locations

10. Cardboard baled & recycled

11. Food digester The bio digester synthesises food waste to a liquid which is high in bacteria beneficial to sewerage treatment plants. This liquid is discharged down the waste pipe.  This eliminates food waste being put into food waste macerators which use excessive amounts of water and also prevents food waste being put into black waste bags. Rental cost is £4656 pa Savings (reduced water usage, black bag waste savings, reduced electricity use) £35K per annum"

12. Transport projects • New cycle sheds/cycle paths and shower facilities have resulted in an increase in cycling. • Re-launched cycle users group • £65k contribution to P&R scheme • Talking to council on extending the scope of P&R availability • Launching new staff permit system in this month which will reduce staff cars on site • Half price parking for official car sharers • Discounted bus tickets for staff • Procurement Strategy will reduce deliveries

13. Cycle sheds everywhere!

14. Energy Centre • 4 Robey boilers (age 1978 -1984) 2720, 5440, 6800, 6800 kg/hr • 2 older than the boiler house itself! • 2 with severe cracks necessitated hire of temp boiler • Annual elec consumption: 8,751,623 kWh (60%) • Annual gas consumption: 5,966,940 kWh (40%) • 3 options for evaluation: • New steam plant to replace existing • Integrating a CHP unit but use ‘good’ existing boilers • Integrating a CHP unit with new boiler plant (Also need to replace TDS, bottom blowdown, flues, pumps etc.)

15. Existing Boilers

16. Energy Centre • Preferred option: • CHP sized at 2000 kWe gas fuelled • Heat recovery from jacket and LTHW from jacket cooling • 1 Combination waste heat/fired steam boiler + economisers • 2 x 7,500 kg/h dual fuel steam boilers + economisers • Procurement: NIFES acting as lead consultant recommended 4 separate packages: • Enabling work, to connect temp boilers, etc. • Supply of temporary boilers, to allow strip out of boiler house • M&E installation work of all new plant • Procurement of plant (through OJEU tender)

17. Energy Centre • Capex £4.8M incl VAT & fees • Estimated annual saving of £700k (gross) • Simple payback of 6.8 years • c. £300k nett savings allowing for capital charges • IRR 9.8% • Estimated annual carbon savings of 3,140 tonnes • Maintenance of boilers by in-house staff • Maintenance of CHP manufacturers, tendered and evaluated with the plant • Project completed Nov 2011 • All plant is UK manufactured

18. New Energy Centre

19. Mini CHP’s • 3 to be installed in residential blocks to replace LTHW boilers • 30kW heat & 15kW electrical output • Toyota gas fired engines in acoustic cabinet, guaranteed for 24 million ‘miles’ • Ability to export to the grid, heat dump vessel • Cap ex justified as the units are replacing aged inefficient boilers • c. £80k Cap ex with £4k pa saving in energy but this must be set against a spend of c. £30+k to replace with LPHW boilers.

20. Installed mini CHP

21. Other stuff! • 250mm roof insulation in some blocks • Investment in BMS and other controls • LED lighting across the hospital site: • All external lighting • Corridors • Successful trial in wards • Procurement Strategy • ‘Sustainable’ service/product part of evaluation criteria • Bulking orders to decrease deliveries • Engage supply chain in sustainable initiatives
