  1. Officers meetingTuesday 16 - 12 - 2008 Environment & Energy At Warwick University The Estates Office

  2. Agenda • Environment & Utilities team Role & Responsibilities • The big picture How do we compare with others • What have we achieved • What are the projects How do we support them • We need your contribution

  3. 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)

  4. Mike Stacey Head of Estates Services Joel Cardinal Energy Manager Nick Hillard Environment Manager Andy Leeson Utilities / Projects Engineer Mark Jarvis Utilities Technical Assistant < vacant > Utilities Technical Assistant The Team Staff Properties Services Building Maintenance Estates Projects Purchasing M & E design Finance Students

  5. The aim • Environment & Energy are working toward same goal • Optimise use of resources • In today’s economy resources are scarce and expensive. • food & drink, supplies and packaging • Energy Gas, Electricity • Water • The aim is to control costs implications • Cost of waste • Cost of Energy procurement • Raise awareness to students and staff

  6. Environment Waste policy Waste control Environment communication Carbon Footprint Support national CO2 target Utilities Procurement Consumption monitoring Invoices - recharges Legal reporting (EUETS, CRC, CHPQA, CCL) Energy & CO² saving projects Area of collaboration Raise awareness Together Change mentalities Gain commitment

  7. Utilities team Role & Responsibilities • Gather utility market information • Purchasing recommendation • Monitoring & Targeting • Design & maintain automatic metering • Report utility consumption across site • Set Targeting

  8. Utilities team Role & Responsibilities • Advise on Energy and CO2 reduction • Conduct buildings energy audit • Manage projects • Report carbon emissions (EUETS, CRC) • Energy advice on buildings • Promote Energy Awareness University

  9. EU ETS Large EU emitters to monitor and report annual CO2 emissions from the use of Gas. Surrender (give back) to the government emission allowances equivalent CO2 emissions In place since 2005 CRC Allemissions not monitored by EU ETS or Climate Change Agreements Includes electrical emissions Cover large businesses and public sector whose annual electricity use >= 6,000,000 kWh Start 1st of Jan 2010 What is it UoW allowances = 25,000 tonnes/pa • Free allocation, so far • Possibility that 2013 allowances must be purchased. • Possible UoW impact ~£534,000 (~£21/Tonne) UoW allowances cost is estimated approx. £115,000 per annum.

  10. EPC Energy Performance Certificates To help improve the energy efficiency of buildings. From October 2008 Mandatory for built, sold or lease Provides 'A' to 'G' ratings for the building 'A' = most energy efficient 'G' being the least Average up to now being 'D'. Accredited energy assessors produce EPC’s Certificate Report suggests energy efficiency improvements DEC Display Energy Certificates Energy usage in operation Help public to see the energy efficiency Consumption records for gas, electricity and other meters. From 1 October 2008. Displayed and visible at all times Mandatory for: buildings >= 1,000m2 Occupied by a public authority and institution providing a public service Valid for one year. The accompanying Advisory Report is valid for seven years. Advisory Report Cost effective measures to improve building rating What is it • “What the car is capable of” • “How the car is driven”

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

  12. University of Warwick Turnover(since foundation in 1964)

  13. Turnover projection

  14. Energy UseKey Performance Indicators (main campus + HRI) • Consumption = c.180 million kWh (161 main campus only) • Energy spend = c.£8 million • Circa 2% of turnover • Carbon footprint = c.42,000 tonnes CO2 (38,000 main campus only) • Overall target to reduce CO2 footprint by • - 10% by 2010/11 (Gov. target -20% by 2020)

  15. How do we compare to others Cost of our properties Total property costs (D26) per student FTE (D4) C1 (All data)

  16. How do we compare to others

  17. How do we compare to others

  18. Energy UseVolume Total energy Use (GWh) Year

  19. Energy Costs As of 1st Oct 2008

  20. Current Density is 387 Kwh/m2/annum If not improvement consumption will increase from 180 to 227 million Kwh/a Cost risk = c.£12.5 million CO2 target is -20% by 2020 Energy density must be improved by 6% year to meet 2020 CO2 target New build / Refurbishment to be exemplar Energy UseDensity (£) (Million Kwh/a) (Kwh/m2/annum)

  21. Carbon Emissions

  22. What have we achievedEnergy 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

  23. What have we achievedEnergy ManagementCHP 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 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.

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

  25. How CHP works

  26. What has been achievedEnergy 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 achievedEnergy 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: • Power : 12MWe => c.£3,000,000 • Heat : 6MWth=> c.£1,000,000 • Water : 150,000m3 => 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 / m2 for whole life • Passivhaus benchmark ~ 100 vs 387 kwh/m2/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/tCO² / 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? • Food for thought • What people say • Your personal contribution

  37. 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 left on standby vs switched off costs up to £10pa.

  38. What people say

  39. Energy Saving Initiatives “7% reduction in electricity use” “45 pledges received” “CIBSE Campaign” “Be an Energy Scrooge this Christmas”

  40. Energy saving initiatives Student-led environmental action week – showcases, seminars, petitions, parties etc • “StudentSwitchOff” • 8.6% average reduction • >500 tonnes CO2 The Carbon Academy is an NUS Services project, supported by NUS, People and Planet and the Environmental Association of Universities and Colleges.

  41. What can you do? • “Free” actions at minimal constraints can save £000’s /annum • Vending machines • 100+ machines to be switched off at night and week end • Can save £6,000 per year • Water dispensers • Can save £6000 Stop chilled water dispensers • 350 on site @ 1 Kwh / 24h each • Can save £14,000 per year • Computers • 7,000 computers. Assume 10% remain on at night and week end • Can save £65,000 per year • This money could be invested in larger Energy & CO² savings projects

  42. What can you do? • 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

  43. Energy Champions Network • Energy consumption is a daily battle • As senior officers you are key enablers • What can you act on from tomorrow in your area • Estates will facilitate the Energy Champions Network • Estates will act on all projects to improve energy and CO2 performance

  44. Thank You • Any comments / suggestions • Joel Cardinal: ext. 50973 • Andy Leeson: ext. 72612 • Mark Jarvis: ext. 74209 • Nick Hillard: ext. 23404 Switch OFF before you leave for holidays
