  • Transcript

    • 1. Nottingham City, Meadows Ozone Project An area based approach, developing sustainable energy communities
    • 2. Nottingham
      • Population around 280,000
      • East Midlands Region
      • Robin Hood!
      • Twinned with Karlsruhe since 1969
    • 3. What is the Ozone
      • National Lottery Funding bid lead by Nottingham City Council for £38m. Built around regenerating a rundown inner city park and creation of community facilities
      • Headline aims:
      • Lowering the carbon footprint of the Meadows Community
      • Creating training and learning opportunities
      • Revitalising Victoria Embankment Park area as a community resource
      • Health Improvements ( through park sport facilities )
      • Generating low cost heat and power to Meadows Community
    • 4. Our role
      • To assess the possible scope in moving this community towards low carbon - targets
      • To identify opportunities for sustainable energy technologies + their integration into social and economic regeneration.
      • To develop programmes and tools to enable community to reduce its carbon footprint.
    • 5. The Meadows Area 3,800 homes 1,300 energy inefficient, 100 yr old solid wall (mostly privately owned) 2,500 energy efficient 1980’s (mostly social housing) Area of multiple deprivation High (32%) fuel poverty (10%+ household income spent on fuel) Since 1990 significant work already carried out on social housing (boilers/insulation)
    • 6.  
    • 7. Why The Meadows area
      • UK target- 60% CO2 reduction on 1990 by 2050
      • Building regulations and planning- all new housing to Zero Carbon by 2016
      • 60% of current housing stock will still be here in 2050.
      • Mixture of new + old housing, social + private ownership
      • Greater appetite for energy/money saving measures
      • Need to support communities to adapt, especially low income.
      • Global/national issue reduced to a manageable scale.
      • Local social pressure and empowerment, identity + cohesion.
    • 8. Lots of data needed
      • Range/distribution of property types
      • Range/distribution of tenancy types
      • Renewable resource potential in area
      • Renewables supply chain potential
      • Relevant National domestic funding streams
      • Energy assessment of typical property types
      • Suitable domestic carbon saving measures
      • Potential carbon savings from all applicable measures
      • Carbon savings already made since 1990
      • Total potential carbon savings and costs
      • Community consultation/involvement on options
    • 9. Typical ‘Old Meadows’ House
      • Old Meadows-Typical 1900’s end terrace,
      • 8.8 tonnes of CO2 per year
      • 38,000kWh pa gas
      • 3,488kWh pa electricity
      • 65% efficient boiler
      • After modern boiler, grid green electricity, solid wall insulation, roof insulation, low-e lights.
      • 3.8 tonnes CO2
      • 19,500 kWh pa gas use.
      • Costing around € 11,500-13,000
      • Saving up to € 1000 pa
    • 10. Typical ‘New Meadows’ house
      • Local authority owned
      • Already cavity filled walls
      • Already double glazed
      • Already well insulated
      • Boiler upgrades possible,
      • in process by LA
      • 9,500kWh pa gas
      • 1,800 kWh pa electricity
      • Very little left to do except District Heating or biomass boilers

    • 12. The Area Renewables Potential
      • 3,800 domestic rooftops, 900 with SW-SE facing roofs for PV, 1900 E-W for SWH. But low income area .
      • 1 large wind turbine (330kW-150 homes)
      • Large PV array (70kWp-16 homes)
      • Switching to green electricity supplier
      • City District Heating possible (800m), expensive
      • Biomass district heating (small clusters)
      • River not suitable, very low head
      • Small wind not suitable, high density housing.
      • Individual biomass not suitable
    • 13.  
    • 14. Energy efficiency opportunities
      • Boiler and control upgrades covered by building regulations; people just repair though, don’t replace. Access to financing/grants as and when needed.
      • Loft insulation
      • Solid wall insulation, expensive and disruptive, needs to be done as and when possible. Access to financing/grants.
      • Energy efficient appliances-affordable financing needed
      • Education
    • 15. Programmes to suit community
      • Turbine revenue to fund Community Energy Manager, who will work towards setting up a community energy company with energy industry partner.
      • Set up local Energy Learning Centre linked with community training and schools
      • Local refurbished (almost!) Zero Carbon exemplar house.
      • Later turbine subsidises a green electricity switch incentive fund.
      • Green loans programme 0%/low interest finance for renewables and energy efficiency measures. Interest rebated annually.
      • Local energy advisor/visitor
    • 16. Achievable target
      • Realistically (without buying everyone SWH and dry lining) likely to be able to reduce footprint by around 44% on 1990
      • Intensive education maybe a little more
      • District heating could push this further, major investment.
      • Community biomass also with major investment.
    • 17. Energy Learning Centre
    • 18. Energy Pavilion +PV array
    • 19.
      • Tower to showcase renewable and sustainable energy technologies
      • Energy storage, water tower/hydrogen
      • WSHP
      • Vertical/horizontal wind
      • Human power
      • Regenerative breaking
      • Natural ventilation
      • Physical Exercise
      • Community space
      • Visitor attraction
    • 20.  
    • 21. Capital Funding
      • Some revenue, ie trainer and energy manager
    • 22. Revenue funding
      • Seeking partners for IEE bid to establish a Sustainable Energy Community.
      • Fund local energy advisors/champions and volunteer programme.
      • With NEA + local community to develop a Community Energy Company to sell green electricity and manage loans for energy efficiency locally, with energy company partner.
      • Results of capital bid known in November
