  1. Practical Measures to Tackle Climate Chaos David Somervell, Energy & Sustainability Manager University of Edinburgh – Estates & Buildings Department13 Infirmary Street, Edinburgh EH1 1LT Tel 0131 650 2073 http://www.eso.ed.ac.ukDavid.Somervell@ed.ac.uk

  2. Universities and Colleges • Crisis? What Crisis? [It is for real] • How will this affect our institution? • Developing a Strategic Approach • Invest now in Utilities Infrastructure • Decentralised Energy on Campus

  3. Facts & Trends IPCC Scenarios 1000 ppm °C 16 14 6 - Further rises to 2300 2050 6-7 GtC reduction 12 5 - 550 ppm 10 4 - Facts & Trends 9 GtC world 450 ppm 8 3 - 2100 range WRE 1000 (IPCC) WRE 550 (IPCC) WRE 450 (IPCC) 6 2 - 4 13 2 1 - 2025 1.3 GtC reduction 11 Global Carbon Emissions, GtC 2000 2010 2020 2030 2040 2050 9 BAU Pathways to 2050 7 2000 2010 2020 2030 2040 2050 Projections & Required Reductions By 2050 we must cut CO2 emissions by 7 GtC with a 1.3 GtC cut by 2025, against projected ‘Business as Usual’. Global Carbon Emissions, GtC 1990

  5. What’s needed? • Interested, Enthusiastic People • Senior Management Support • Allocation of Resources (Money) PLUS … Some Measure of Luck / Timing!

  6. Edinburgh:“University in the City”… invested £12million in Decentralised Energy / CHP 2002-2005  George Sq 1.6MWe CHP  Pollock Halls 526kWe CHP King’s Bldgs 2.7MWe CHP 

  7. Edinburgh’s 3 CHP Projects • Pollock Halls: 526kWe engine serving student residences as lead boiler – 2003 • The King’s Buildings: 2.7MWe engine displaced old steam system + 2 new 7.5MW LTHW boilers serving high base load – 2004 • George Square: 1.6MWe engine again replaced steam system – plus 75 tonne Heat Store and 600kW Absorption Chiller to even out load – 2005

  8. UK Energy Flows – 50% wasted

  9. Combined Heat and Power

  10. George Sq: Trigeneration

  11. George Square Energy Centre

  12. George Sq buildings now linked:

  13. First remove old steam boilers…

  14. 1.6MWe Alternator bolts on

  15. High Efficiency, Low NOx Boiler

  16. 75 cubic metre Thermal Store

  17. 12 cylinder Jenbacher Engine • GE Jenbacher 612 Engine

  18. 600kWAbsorption Chiller

  19. Thanks to our CHP Partners • Energy Saving Trust – for funding support • PB Power – for Scheme Design • Crown House Technologies – Main Contractor • Estates & Bldgs Works Div’n – implementation • Clarke Energy – Jenbacher Maintenance www.eso.ed.ac.uk

  20. Rankine Engineering Building

  21. Building Integrated PhotoVoltaics

  22. Why we have done this …? • Save money long-term • Invest in infrastructure • Annual Carbon savings • Leadership role

  23. …because there is only 1 planet
