  • Nottingham City, Meadows Ozone Project An area based approach, developing sustainable energy communities
  • Nottingham
    • Population around 280,000
    • East Midlands Region
    • Robin Hood!
    • Twinned with Karlsruhe since 1969
  • 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
  • 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.
  • 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)
  • 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.
  • 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
  • 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
  • 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

  • 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
  • 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
  • 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
  • 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.
  • Energy Learning Centre
  • Energy Pavilion +PV array
    • 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
  • Capital Funding
    • Some revenue, ie trainer and energy manager
  • 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
