19 Edinburgh: University in the City … invested £12million in Decentralised Energy / CHP Pollock Halls 526kWe CHP Kings Bldgs 2.7MWe CHP George Sq 1.6MWe CHP

20 Edinburghs 3 CHP Projects 1.Pollock Halls: 526kWe engine serving student residences as lead boiler – The Kings Buildings: 2.7MWe engine displaced old steam system + 2 new 7.5MW LTHW boilers serving high base load – George Square: 1.6MWe engine again replaced steam system – plus 75 tonne Heat Store and 600kW Absorption Chiller to even out load – 2005

21 UK Energy Flows – 50% wasted

22 Combined Heat and Power

23 George Sq: Trigeneration

24 George Square Energy Centre

25 George Sq buildings now linked:

26 First remove old steam boilers…

27 1.6MWe Alternator bolts on

28 High Efficiency, Low NOx Boiler

29 75 cubic metre Thermal Store

30 GE Jenbacher 612 Engine 12 cylinder Jenbacher Engine

31 600kW Absorption Chiller

32 Thanks to our CHP Partners Energy Saving Trust – for funding support PB Power – for Scheme Design Crown House Technologies – Main Contractor Estates & Bldgs Works Divn – implementation Clarke Energy – Jenbacher Maintenance

33 Rankine Engineering Building

34 Building Integrated PhotoVoltaics

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

36 …because there is only 1 planet
