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’.

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
