2 brainstorming exercises to capture your ideas

Brainstorm 1 Working in pairs

Discuss your domestic energy situation:

Energy provider

Annual costs / recent increases

Energy conservation measures

Be prepared to share the findings with the group

Energy Management

“..I would particularly urge everyone to reflect on energy use and make special effort to turn off PCs and lights when not in use”

Prof. Nigel Thrift, Vice-Chancellor (14th October 2008)

Consumption = c.180 million kWh

Energy spend = c.£8 million

Circa 2% of turnover

Carbon footprint = c.42,000 tonnes CO2

Overall target to reduce CO2 footprint by

- 10% by 2010/11

Energy Management

Energy audits since the 1980’s

Collaborative work between academia and University administration

HE Carbon Management Programme

BREEAM Excellent Target on new builds

Strengthening of energy team

CHP and District Heating Electricity generation (4.7MWe), heating, hot water

and chilled water (14.1MWth)

Capital costs of circa £5M (annual savings in the region of £1M pa.)

>16km u/g pipework covering c.60%

Maintenance costs less cf. stand alone plant

Optimisation of system includes thermal storage, increasing of summer heat load and ongoing system balancing.

Food for thought …5no. 1kW wind turbines

Scheduling 1no. CHP engine to switch offbetween midnight and 5am

5 tonnes per annum

25 tonnes per week

Food for thought … 2kW fan heater is equivalent to running more

than 100 compact fluorescent lights

The standby cost of a vending machine can be £255pa (cf. an overall energy cost of £268)

500W halogen flood lights can be replaced by 60W low energy alternatives

A computer monitor left on standby cf switched off costs up to £10pa.

Campus development - business as usual:

Power : 12MWe => c.

£3,000,000

Heat : 6MWth => c.£1,000,000

Water : 150,000m3 => c.£250,000

Carbon dioxide emissions => c.50%

Future Challenges

The Future Planned additions to the network

Complete “ring” through Warwickshire land

New energy centre on Warwickshire land (biomass fuelled)

More absorption cooling for summer

Replacement of stand-alone boilers

Continue to focus on energy conservation

“45 pledges received”

“7% reduction in electricity use”

“Be an Energy Scroogethis Christmas”

“CIBSE Campaign”

Energy Saving Initiatives

Energy saving initiatives

“StudentSwitchOff”- 8.6% average reduction ->500 tonnes CO2

Student-led environmental action week – showcases, seminars, petitions, parties etc

The Carbon Academy is an NUS Services project, supported by NUS, People and Planet and the Environmental

Association of Universities and Colleges.

Brainstorm 2 Working in pairs/threes

Consider your own work area / general university operation

Identify potential projects in the following areas:

One quick-win electricity saving projects

A high profile renewable energy “showpiece”

One “Off the wall” initiative
