The big picture Ø Income vs energy use Ø How do we compare with other HE Ø What happen if the University grows and we do nothing for energy efficiency 11

University of Warwick Turnover (since foundation in 1964) 12

Turnover projection 13

Energy Use K ey Performance Indicators (main campus + HRI) § Consumption = c. 180 million k. Wh (161 main campus only) § Energy spend = c. £ 8 million § Circa 2% of turnover § Carbon footprint = c. 42, 000 tonnes CO 2 (38, 000 main campus only) § Overall target to reduce CO 2 footprint by - 10% by 2010/11 (Gov. target -20% by 2020) 14

Carbon Emissions 21

What have we achieved Energy Management § Energy audits since the 1980’s § Collaborative work between academia and University administration § HE Carbon Management Programme § Save 10% of our carbon footprint § BREEAM Excellent Target on new builds § Strengthening of energy team 22

What have we achieved Energy Management CHP and District Heating § Electricity generation (4. 7 MWe) § Heating, hot water and chilled water (14. 1 MWth) § Capital costs of circa £ 5 M § Annual savings in the region of £ 1 M pa. § >16 km u/g pipe work 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. 23

24

Food for thought … 2 no. 1 k. W wind turbines 5 tonnes per annum Scheduling 1 no. CHP engine to switch off between midnight and 5 am 25 tonnes per week 25

How CHP works 26

What has been achieved Energy Management § Because CHP are more efficient they attract tax benefits § CCL: Carbon Charge Levy (reduce the costs of the Gas we buy) § CHPQA: Quality assurance for CHP (enhanced capital allowance – for private businesses) 27

What we have achieved Energy Management § BMS: Building Management System § Give remote information and control § Allow to switch On/Off heating and cooling plants according to schedules § Art Centre is flexible for all performances § Allow variable drive to heating and air handling § Cost savings on energy § Monitor presence and comfort (CO²) 28

Future Challenges § Campus development - business as usual: Ø Power : 12 MWe => c. £ 3, 000 Ø Heat : 6 MWth => c. £ 1, 000 Ø Water : 150, 000 m 3 => c. £ 250, 000 § Carbon dioxide emissions => up to c. 50% 29

The Future § Given the projected campus growth and intensification of the research aspects of the University’s operation – it is unlikely that overall energy consumption will fall. § It will however be necessary for the carbon intensity of the University’s energy procurement to fall (partially through mandate). § Local ownership, empowerment and ideas generation will be essential to the reduction of energy consumption per square unit. 30

What is the strategy § Energy providers § requested for extra capacity § CHP + District Heating extension § Biomass CHP to save 3, 500 t CO² § Design Energy lean buildings § Reduce energy use / m 2 for whole life § Passivhaus benchmark ~ 100 vs 387 kwh/m 2/a today § Involve staff and students to gain buy-in and accountability 31

What are the projects § Planned additions to the network § Complete “ring” via Warwickshire land § New energy centre on Warwickshire land (biomass fuelled) § More absorption cooling for summer § Replacement of stand-alone boilers 32

What are the projects § Improve synergies § Utilities part of design team from project kick off § Activate the Energy Champions network § Share best practices and opportunities. § Obtain students and staff buy-in § Reinforce energy audits § Analysis of metering data § Utilities experience and staff feedback § Use of EPC / DEC advisory reports 33

What are the projects § Continue to focus on energy and CO² conservation § Some buildings are heated 24/7 § Some areas do not have thermostatic control § Improve lighting with more efficient fittings § Loft and wall insulation § Install Variable speed drive & Install voltage control 34

What are the projects § Continue to focus on energy and CO² conservation § Adjust lighting control in public areas (Within safety limits) § Install double glazing § Stand by and switch off of PC’s (feasibility pending) § Solar panels applications (thermal and Photovoltaic) § Laundry, HRI glasshouses…. § Natural / reduced air conditioning in IT server rooms 35

How to support the projects? § SALIX revolving green fund § Awaiting final decision after compliance audit § Dedicated to Energy & CO² savings § Combine payback and CO² savings § 5 - 7. 5 years payback and max capital cost £ 50 - 100/t. CO² / LT life § SALIX Transformational fund § Project = Biomass CHP project funding § Extend District heating in south of campus § Increase electricity production by 30%; increase self sufficiency § Save 3, 500 tons CO² additional per year § Increase resources § +2 on Utilities team 36

What can you do? Ø Food for thought Ø What people say Ø Your personal contribution 37
