Universities and Colleges
1. Crisis? What Crisis? [It is for real]
2. How will this affect our institution?
3. Developing a Strategic Approach
4. Invest now in Utilities Infrastructure
5. Decentralised Energy on Campus
By 2050 we must cut CO2 emissions by 7 GtC with a 1.3 GtC cut by 2025, against projected ‘Business as Usual’.

What’s needed?
1. Interested, Enthusiastic People2. Senior Management Support 3. Allocation of Resources (Money)
PLUS … Some Measure of Luck / Timing!

2002-2005

King’s Bldgs 2.7MWe CHP
George Sq 1.6MWe CHP
Edinburgh’s 3 CHP Projects
1. Pollock Halls: 526kWe engine serving student residences as lead boiler – 2003
2. The King’s Buildings: 2.7MWe engine displaced old steam system + 2 new 7.5MW LTHW boilers serving high base load – 2004
3. George Square: 1.6MWe engine again replaced steam system – plus 75 tonne Heat Store and 600kW Absorption Chiller to even out load – 2005
UK Energy Flows – 50% wasted
Combined Heat and Power
George Sq: Trigeneration
